Dualism is a coherent theory of mind and the only tenable one in light of our current scientific knowledge.
6
Which dualism?
5
Do you mean that, without strong evidence that we don't have, we should assume dualism, or that we have strong evidence for dualism?
If it's the second one, can you give me an example of such a piece of evidence?
0
The second position.
An example of the evidence is the two-way causal connection between your inner subjective experiences and the external universe.
5
Indeed. Two way interaction uis as well or better explained by physicalism.
5
I upvoted because I disagree (strongly) with the second conjunct, but I do agree that certain varieties of dualism are coherent, and even attractive, theories of mind.

Wouldn't cognitive science or neuroscience be sufficient to falsify such a theory? All we really have to do is show that "good life", as seen from the inside, does not correspond to maximized happy-juice or dopamine-reward.

The most that would show is what humans tend to prefer, not what they should prefer.

You're going to have to explain what meta-ethical view you hold such that "prefer on reflection given full knowledge and rationality" and "should prefer" are different.

Sufficiently advanced cognitive science definitely will, though.

I can think of something I prefer, on reflection, against wireheading. Now what?
-1
There's a lot of things that people are capable of preferring that's not pleasure, the question is whether it's what they should prefer.
2
Awfully presumptuous of you to tell people what they should prefer.
-1
Why? We do this all the time, when we advise people to do something different from what they're currently doing.
3
No, we don't. That's making recommendations as to how they can attain their preferences. That you don't seem to understand this distinction is concerning. Instrumental and terminal values are different.
-3
My position is in line with that - people are wrong about what their terminal values are, and they should realize that their actual terminal value is pleasure.
1
Why is my terminal value pleasure? Why should I want it to be?
0
Fundamentally, because pleasure feels good and preferable, and it doesn't need anything additional (such as conditioning through social norms) to make it desirable.
-1
Why should I desire what you describe? What's wrong with values more complex than a single transistor?
Also, naturalistic fallacy.
0
It's not a matter of what you should desire, it's a matter of what you'd desire if you were internally consistent. Theoretically, you could have values that weren't pleasure, such as if you couldn't experience pleasure.
Also, the naturalistic fallacy isn't a fallacy, because "is" and "ought" are bound together.
0
Why is the internal consistency of my preferences desirable, particularly if it would lead me to prefer something I am rather emphatically against?
Why should the way things are be the way things are?
0
(Note: Being continuously downvoted is making me reluctant to continue this discussion.)
One reason to be internally consistent is that it prevents you from being Dutch booked. Another reason is that it enables you to coherently be able to get the most of what you want, without your preferences contradicting each other.
As far as preferences and motivation are concerned, however things should be must appeal to them as they are, or at least as they would be if they were internally consistent.
0
Retracted: Dutch booking has nothing to do with preferences; it refers entirely to doxastic probabilities.
I very much disagree. I think you're couching this deontological moral stance as something more than the subjective position that it is. I find your morals abhorrent, and your normative statements regarding others' preferences to be alarming and dangerous.
1
You can be Dutch booked with preferences too. If you prefer A to B, B to C, and C to A, I can make money off of you by offering a circular trade to you.
1
And if I'm unaware that such a strategy is taking place. Even if I was aware, I am a dynamic system evolving in time, and I might be perfectly happy with the expenditure per utility shift.
Unless I was opposed to that sort of arrangement, I find nothing wrong with that. It is my prerogative to spend resources to satisfy my preferences.
0
That's exactly the problem - you'd be happy with the expenditure per shift, but every time a fill cycle would be made, you'd be worse off. If you start out with A and $10, pay me a dollar to switch to B, another dollar to switch to C, and a third dollar to switch to A, you'd end up with A and $7, worse off than you started, despite being satisfied with each transaction. That's the cost of inconsistency.
0
And 3 utilons. I see no cost there.
0
But presumably you don't get utility from switching as such, you get utility from having A, B, or C, so if you complete a cycle for free (without me charging you), you have exactly the same utility as when you started, and if I charge you, then when you're back to A, you have lower utility.
0
If I have utility in the state of the world, as opposed to the transitions between A, B, and C, I don't see how it's possible for me to have cyclic preferences, unless you're claiming that my utility doesn't have ordinality for some reason. If that's the sort of inconsistency in preferences you're referring to, then yes, it's bad, but I don't see how ordinal utility necessitates wireheading.
0
Regarding inconsistent preferences, yes, that is what I'm referring to.
Ordinal utility doesn't by itself necessitate wireheading, such as if you are incapable of experiencing pleasure, but if you can experience it, then you should wirehead, because pleasure has the quale of desirability (pleasure feels desirable).
0
And you think that "desirability" in that statement refers to the utility-maximizing path?
0
I mean that pleasure, by its nature, feels utility-satisfying. I don't know what you mean by "path" in "utility-maximizing path".
-2
Can you define 'terminal values', in the context of human beings?
0
Terminal values are what are sought for their own sake, as opposed to instrumental values, which are sought because they ultimately produce terminal values.
0
I know what terminal values are and I apologize if the intent behind my question was unclear. To clarify, my request was specifically for a definition in the context of human beings - that is, entities with cognitive architectures with no explicitly defined utility functions and with multiple interacting subsystems which may value different things (ie. emotional vs deliberative systems). I'm well aware of the huge impact my emotional subsystem has on my decision making. However, I don't consider it 'me' - rather, I consider it an external black box which interacts very closely with that which I do identify as me (mostly my deliberative system). I can acknowledge the strong influence it has on my motivations whilst explicitly holding a desire that this not be so, a desire which would in certain contexts lead me to knowingly make decisions that would irreversibly sacrifice a significant portion of my expected future pleasure.
To follow up on my initial question, it had been intended to lay the groundwork for this followup: What empirical claims do you consider yourself to be making about the jumble of interacting systems that is the human cognitive architecture when you say that the sole 'actual' terminal value of a human is pleasure?
0
That upon ideal rational deliberation and when having all the relevant information, a person will choose to pursue pleasure as a terminal value.
-3
I've got to give it to you, the human value is not complex point is frankly aging very well with the rise of LLMs, and one of the miracles is that you can get a reasonably good human value function without very large hacks or complicated code, it's just learned from the data.
To put it another way, I think that this contrarian opinion has been receiving Bayes points compared to a lot of other theories on how complicated are human values.
the human value is not complex point is frankly aging very well with the rise of LLMs
You just pointed out that what a LLM learned for even a very simple game with extensive clean data turned out to be "a bag of heuristics": https://www.lesswrong.com/posts/LNA8mubrByG7SFacm/against-almost-every-theory-of-impact-of-interpretability-1?commentId=ykmKgL8GofebKfkCv
2
Alright, I have a few responses to this:
1. Contra OthelloGPT, in the case of GPT-4, and the new o1-preview model, I believe that the neural networks we are focusing on are deep and sort of wide, which I suspect prevents a lot of the "just find heuristic" behavior, and I believe Chain-Of-Thought scaling is there to make the model be biased more towards algorithmic solutions and sequential computation over heuristics and parallel computation.
You even mentioned that possibility here too:
https://www.lesswrong.com/posts/gcpNuEZnxAPayaKBY/othellogpt-learned-a-bag-of-heuristics-1#5K5wDoMD2YtSJvfw9
Well, it would certainly be nice if that were true, but all the interpretability research thus far has pointed out the opposite of what you seem to be taking it to. The only cases where the neural nets turn out to learn a crisp, clear, extrapolable-out-many-orders-of-magnitude-correctly algorithm, verified by interpretability or formal methods to date, are not deep nets. They are tiny, tiny nets either constructed by hand or trained by grokking (which appears to not describe at all any GPT-4 model, and it's not looking good for their successors either). The bigger deeper nets certainly get much more powerful and more intelligent, but they appear to be doing so by, well, slapping on ever more bags of heuristics at scale. Which is all well and good if you simply want raw intelligence and capability, but not good if anything morally important hinges on them reasoning correctly for the right reasons, rather than heuristics which can be broken when extrapolated far enough or manipulated by adversarial processes.
12
We actually have a resolution for the thread on whether LLMs naturally learn algorithmic reasoning as they scale up with COT vs just reasoning with memorized bags of heuristics, and the answer is that we have both real reasoning, which is indicative of LLMs actually using somewhat clean algorithms, but there are also a lot of heuristic reasoning involved.
So we both got some things wrong, but also got some things right.
The main thing I got wrong was in underestimating how much COT for current models still involves pretty significant memorization/bag of heuristics to get correct answers, which means I have to raise the complexity of human values, given that LLMs didn't compress as well as I thought, and the thing I got right was that sequential computation like COT does incentive actual noisy reasoning/algorithms to appear, but I was wrong about the strength of the effect, though I was still right to be concerned about the fact that the OthelloGPT network was very wide and skinny, rather than deep and wide, which makes it harder to learn the correct algorithm.
The thread is below:
https://x.com/aksh_555/status/1843326181950828753
I wish someone is willing to do this for the o1 series of models as well.
One other relevant comment is here:
https://www.lesswrong.com/posts/gcpNuEZnxAPayaKBY/othellogpt-learned-a-bag-of-heuristics-1#HqDWs9NHmYivyeBGk
0
A key crux is that I think those heuristics actually go quite far, because it's much, much easier to learn a quite close to correct model of human values with simple heuristics and internalize the values from it's training data as it's own than it is to learn useful capabilities, and more generally it's easier to learn and internalize human values as it's own than it is to learn useful new capabilities, so even under a heuristic view of LLMs where LLMs are basically always learning a bag of heuristics and don't have actual algorithms, the heuristics for internalizing human values is always simpler than heuristics for learning capabilities, because it's easier to generate training data for human values than it is to generate any other capability.
See below for relevant points:
https://www.beren.io/2024-05-15-Alignment-Likely-Generalizes-Further-Than-Capabilities/
Good point though that the claim that current LLMs are definitely learning algorithms rather than just heuristics was definitely not supported very well by the current interpretability results/evidence, though I'd argue that o1-preview is mild evidence we will start seeing more algorithmic/search parts will be used for AIs in the future (though to be clear I believe a majority of the success comes from it's data being higher quality, and only fairly little to it's runtime search.)

The replication initiative (the push to replicate the majority of scientific studies) is reasonably likely to do more harm than good. Most of the points raised by Jason Mitchell in The Emptiness of Failed Replications are correct.
Imagine a physicist arguing that replication has no place in physics, because it can damage the careers of physicists whose experiments failed to replicate! Yet that's precisely the argument that the article makes about social psychology.
8
I read this trying to keep as open a mind as possible, and I think there is SOME value to SOME of what he said (ie no two experiments are totally the same and replicators often are motivated to prove the first study wrong)... But one thing that really set me off is that he genuinely considers a study that doesn't prove its hypothesis as a failure, not even acknowledging that IN PRINCIPLE, this study has proven the hypothesis wrong, which is valuable knowledge all the same.
Which is so jarring with what I consider the very basis of science that I find difficult to take Mitchell seriously.
Open borders is a terrible idea and could possibly lead to the collapse of civilization as we know it.
EDIT: I should clarify:
Whether you want open borders and whether you want the immigration status quo are different questions. I happen to be against both, but it is perfectly consistent for somebody to be against open borders but be in favor of the current level of immigration. The claim is specifically about completely unrestricted migration as advocated by folks like Bryan Caplan. Please direct your upvotes/downvotes to the former claim, rather than the latter.
[Please read the OP before voting. Special voting rules apply.]
Current levels of immigration are also terrible, and will significantly speed up the collapse of the Western world.

I'm not clear on whether it's actually a good idea, but if Bryan Caplan's arguments are the best available, it's definitely a horrible idea. He sidesteps all the potential problems without addressing them, or in some cases draws analogies that, when actually considered properly, indicate that it would be a bad idea.
7
I particularly like how he manages to switch between deontology and consequentialism in the same argument.
3
Actually here I disagree. There are many counterarguments listed on the Open Borders site, and for that I give him credit. Especially as he actually attempts to engage with racialist arguments, rather than dismissing them.
6
I remember at one point encountering the Open Borders site, considering that it sounded like a pretty good idea, then reading through much of the site and becoming decreasingly convinced as I read the specific arguments, which consisted of more holes than solid points.
Recently, it's come up again, specifically in an interview with Caplan which was going around (I saw it via Kaj). Again, I was initially intrigued by the idea, but the more I saw of the actual arguments, the weaker they seemed. He seems to routinely deflect the significant concerns with non-denials and never actually address the pragmatic reasoning against it.
0
I'm not sure if it's a technique worth crediting. There are voting trend issues with Hispanic immigrants that do not boil down to paranoid delusions about the Reconquista, and there are arguments regarding crime and immigration that are strongly and obviously distinguishable from sending every African-American person -- including those innocent of any crime -- out of the country. I'm hard-pressed to believe those arguments were selected for any reason but their weakness and unpalatability.
I personally favor reduced barriers to immigration (outside of a criminal background check and unique person identification, the modern limits are counterproductive at best), but writing up the worst arguments against that belief doesn't really strengthen them.
1
Hey, it's a step up from denying outright that certain types of immigrants will commit more crimes. A lot of people have drank that Kool-Aid.
2
Why do you believe this? Countries with the most liberal immigration policies today don't seem to be on the verge of collapse.
3
Ebola?
4
Ebola is more an argument for colonialism than against open borders but let's not be picky.
9
Ebola is an example of a locally-originated virulent existential threat open borders fail to contain, biological, social or otherwise. Controlled borders, despite all the issues, at least can act as an immune system of sorts.
3
Define "controlled borders"? In the "open borders" context the debate is usually about residency and citizenship restrictions, but in the context of ebola those don't matter; tourists and airline workers and cargo ship crews and so on all carry diseases too.

You should visit Bradford someday.
6
I'm sure Bradford isn't the greatest place to live, but (1) it's better than many US inner cities, (2) the UK seems quite far from collapse, and generally (3) "such-and-such a country allows quite a lot of immigration, and there is one city there that has a lot of immigrants and isn't a very nice place" seems a very very very weak argument against liberal immigration policies.
8
On the other hand, "such-and-such a country allows quite a lot of immigration, and the niceness of a city inversely correlates with the number of immigrants there" is a stronger argument. Especially if I can get an even stronger correlation by conditioning on types of immigrants.
7
Stronger, yes. But ...
* It's far from clear that the central premise is correct. (Cambridge has a lot of immigrants and I think it's very nice. I'm told Stoke-on-Trent is pretty rubbish but it has few immigrants. Two cherry-picked cases don't tell you much about correlation but, hey, that's one more case than bramflakes offered.)
* The differential effects of immigration within a country might look different from the overall effects on the country as a whole. (Toy model, not intended to be a description of how things actually are: suppose some immigrant group produces disproportionate numbers of petty criminals and brilliant business executives; then maybe areas with more of that group will have more crime but by the magic of income tax the high earnings of the geniuses will make everyone better off.)
* For some people -- I am not claiming you are one -- the very fact that a place has more immigrants (or more of particular "types of immigrants", nudge nudge wink wink) makes it less nice. Those who happen not to feel that way may have a different view of the correlation between niceness and immigration from those who do. To take a special case, the immigrants themselves probably don't feel that way, and for some who favour liberal immigration policies the benefit to the immigrants is actually an important part of the point.
3
Actually they probably do. That's why they immigrated in the first place.
Well it's remarkable how strong a correlation there is between one's support for immigration and how strong a bubble one has around oneself to protect oneself from them. Look how many of the most prominent immigration advocates live in gated communities.
5
I can think of reasons why someone might migrate from country A to country B other than preferring country B's people to country A's.
[EDITED to add: Maybe I should give some examples, in case they really aren't obvious. Country B might have: a better political system, less war, more money, better treatment for some group one's part of (women, gay people, intellectuals, Sikhs, ...), less disease, nicer climate, lower taxes, better public services, better jobs, better educational opportunities. Some of those might in some cases be because country A's people are somehow better, but they needn't be, and even if in fact Uzbekistan has lower taxes because it has fewer Swedes and Swedes have a genetic predisposition to raise taxes, someone migrating from Sweden to Uzbekistan for lower taxes needn't be aware of that and needn't have any preference for not being around Swedes.]
I am interested: How strong, and how many? Do you have figures?
(And how does it compare with how many of the most prominent advocates of anything you care to mention live in gated communities? The most prominent people in any given group are more likely to be rich, and richer people more often live in gated communities.)
In any case, assuming for the sake of argument that there is indeed a positive correlation between being "protected" from immigrants and supporting letting more of them in: I don't understand how your reply is responsive to what I wrote. It seems exactly parallel to this: "Many people advocate prison reform for the sake of the prisoners." "Oh year? Well, a lot of those people prefer to live in places with lower crime rates." Which is true enough, but hardly relevant. There's no inconsistency between wanting some group of people to be better off, and having a personal preference for not living near a lot of them.
5
Rich people are more likely to advocate open boarders.
As for prominent people: Mark Zuckerberg bought the four houses surrounding his own "because he wanted more privacy". Bryan Caplan prides himself on the bubble he's constructed around himself.
3
Again, I'd be interested in the statistics. (That isn't a coded way of saying I think you're wrong, by the way. But I'd be interested to know how big the differences are, whether it depends on what you mean by "rich", etc.)
I'm not sure why this is relevant. I'm guessing that both of those people advocate open borders, but surely the absolute most any observation of this form could show is that there are at least two people in the world who advocate open borders for bad reasons, or advocate open borders but are terrible people, or something. How can that possibly matter?
4
Of course, one consequence of this is that if enough Swedes migrate they'll destroy the aspect of Uzbekistan that attracted them in the first place.
It is hypocritical in the original sense of the term, the one from which the word's negative connotations derive, i.e., a leader who insists that the group make sacrifices for the "greater good" without participating in those sacrifices himself.
1
Until the number of Swedes in Uzbekistan is extremely large, it'll presumably still be better than Sweden in that respect.
That doesn't actually seem to be the original sense of the term, at least according to my reading of the OED, but I don't think it matters. Anyway, let's suppose you're right and some advocates of liberal immigration policies are hypocrites in that sense. I don't see how that's evidence that the policies are bad, nor do I see how it's responsive to what your comment was a reply to (namely, a claim that many people advocate liberal immigration policies for the benefit of the immigrants).
I'm still curious about "how strong, and how many", by the way. I assume, from what you said on this point, that you have figures; I'd love to see them.
0[anonymous]
Other than climate and to some extent money and war and disease, these mainly depend on which kind of people Country B has.

I'm being flippant of course. I didn't intend it as a serious argument.
Quick response:
1) You cannot compare the UK's cities to the US' cities because the US has a 14% black population and the UK does not. "Inner city" is a codeword for the kind of black dysfunction that thankfully the UK does not possess.
2) The UK is not close to collapse because we don't have fully Open Borders yet. For all its faults, the EU's migration framework isn't quite letting in millions of third-worlders yet.
3) Of course.
If you don't mind, I don't want to get into a lengthy debate on the subject.

The difference is only apparent; both societies have treated their nonwhites like trash. The British Empire merely avoided its "dysfunction" problem at home by outsourcing it to India.

Then why, despite the xenophobic laws of the 19th and early 20th centuries, are East Asians a dominant minority in the US? Why, despite a millenium of antisemitism, are Ashkenazim getting 27% of Nobels and making up about quarter [edit: not sure of exact number] of US billionaires?
White people have treated all nonwhites like trash at some point or another, yet there's a giant variation in outcomes. Racism as an all-powerful explanation of black dysfunction is untenable.

"The territory" is just whatever exists. It may well be an infinite series of entities, each more refined than the last. It's still a territory.
If there is no territory, what is a map?
5
I don't normally call it a map, I call it a model, but whatever the name, it's something that turns observations into predictions of future observations, without claiming that the source of these observations is something called "reality". This can go as much meta as you like. The map-territory model is one such useful model, except when it's not.
1
Are you saying that the universe is built like Solomonoff induction? It randomly produces observations and eliminates possibilities that don't follow them? I'd still consider that as having a territory, but it's certainly contrarian.
At the very least, your model if the universe implies the existence of a series of maps along a timeline.
5
I think this post should win the thread for blowing the most minds. (I'll upvote even though I think your position is tenable, since I only assign it 20% probability or so.)
1
I think the whole point is that there's no fact of the matter. "There are only maps" is a map, and on its own logic it's only as true as it is useful. I'm not sure how I would assign a probability to it.

I'm lost at "socially agreed". I define models as useful if they make good predictions. This definition does not rely on some social agreement, only on the ability to replicate the tests of said predictions.

Can you unpack this? At the moment it seems nonsensical, in a "throwing together random words and hoping people read profound insights into it" way.
7
Sure. Have you actually seen "the territory"? Of course not. There are plenty of unexplained observations out there. We assume that these come from some underlying "reality" which generates them. And it's a fair assumption. It works well in many cases. But it is still an assumption, a model. To quote Brienne Strohl on noticing:
To most people the map/territory observation is such a "one and the same". I'm suggesting that it's only a hypothesis. It gives way when making a map changes the territory (hello, QM). It is also unnecessary, because the useful essence of the map/territory model is that "future is partially predictable", in a sense that it is possible to take our past experiences, meditate on it for a while, figure out what to expect in the future and see our expectations at least partially confirmed. There is no need to attach the notion of some objective reality causing this predictability, though admittedly it does feel good to pretend that we stand on a solid ground, and not on some nebulous figment of imagination.
If you extract this essence, that future experiences are predictable from the past ones, and that we can shape our future experiences based on the knowledge of the past, it is enough to do science (which is, unsurprisingly, designing, testing and refining models). There is no indication that this model building will one day be exhausted. In fact, there is plenty of evidence to the contrary. It has happened many times throughout human history that we thought that our knowledge was nearly complete, there was nothing more to discover, except for one or two small things here and there. And then those small things became gateways to more surprising observations.
Yet we persist in thinking that there are ultimate laws of the universe, and that some day we might discover them all. I posit that there are no such laws, and we will continue digging deeper and deeper, without ever reaching the bottom... because there is no bottom.
3
Thanks for explaining, upvoted. But I still don't see how this could possibly make sense.
But our models have become more accurate over time. We've become, if you will, "less wrong". If there's no territory, what have we been converging to?
...Yes? I see it all the time.
I seem to recall someone (EY?) defining "reality" as "that which generates our observations". Which seems like a fairly natural definition to me. If it's just maps generating our observations, I'd call the maps part of the territory. (Like a map with a picture of the map itself on the territory. Except, in your world, I guess, there's no territory to chart so the map is a map of itself.) This feels like arguing about definitions.
I see how this might sorta make sense if we postulate that the Simulator Gods are trying really hard to fuck with us. Though still, in that case, I think the simulating world can be called a territory.
3
Indeed they have. We can predict the outcome of future experiments better and better.
We've become, if you will, "less wrong".
Yep.
If there's no territory, what have we been converging to?
Why do you think we have been converging to something? Every new model asks generates more questions than it answers. Sure, we know now why emitted light is quantized, but we have no idea how to deal, for example, with the predicted infinite vacuum energy.
No, you really don't. What you think you see is a result of multiple layers of processing. What you get is observations, not the unfettered access to this territory thing.
It is not a definition, it's a hypothesis. At least in the way Eliezer uses it. I make no assumptions about the source of observations, if any.
First, I made no claims that maps generate anything. maps are what we use to make sense of observations. Second, If you define the territory the usual way, as "reality", then of course maps are part of the territory, everything is.
Not quite. You construct progressively more accurate models to explain past and predict future inputs. In the process, you gain access to new and more elaborate inputs. This does not have to end.
I realize that is how you feel. The difference is that if the assumption of the territory implies that we have a chance to learn everything there is to learn some day, construct the absolutely accurate map of the territory (possibly at the price of duplicating the territory and calling it a map). I am not convinced that it is a good assumption. Quite the opposite, our experience shows that it is a bad one, it has been falsified time and again. And bad models should be discarded, no matter how comforting they may be.
0
You could argue that sensing is part of the territory while any thing that is sensed is part of the map, I think.
0
You could, but you should be very careful, since most of sensing is multiple levels of maps. Suppose you see a cat. So, presumably the cat is part of the territory, right? Well, let's see:
* what you perceive as a cat is constructed in your brain from genetics, postnatal development, education, previous experiences and nerve impulses reaching your visual cortex. There are multiple levels of processing: light entering through your eye, being focused, absorbed by light-sensitive cells, going through 3 or 4 levels of other cells before triggering spikes in the afferent fibers reaching deep into your visual cortex. The work done inside it to trigger "this is a cat" subroutine in a totally different part of the brain is much much more complex.
* Any of these levels can be disrupted, so that when you see a cat others don't agree (maybe someone drew a "realistic" picture to fool you, or maybe your brain constructed a cat image where that of a different but unfamiliar animal (say, raccoon) would be more accurate). Multiple observations are required to validate that what you perceive as a cat behaves the way your internal model of the cat predicts.
* Even the light rays which eventually resulted in you being aware of the cat are simplified maps of propagating excitation of the EM field interacted with atoms in what could reasonably be modeled as cat's fur. Unless it is better modeled as lines on paper.
* This stack of models currently ends somewhere in the Standard Model of Particle physics. Not because it's the "ultimate reality", but because we don't have a good handle on how to continue building the stack.
* You could argue that all the things I have described are "real" and part of the territory. Absolutely you can. But then why stop there? If light rays are real and not just abstractions, then so are images of cats in your brain.
* Thus any model is as "real" as any other, though one can argue that accurate (better at anticipating future experiences) model a

By "sensing" I was referring to the end result of all those nerves firing and processes processing when awareness meets the result of all that stuff. I suppose I could have more accurately stated that awareness is a part of the territory as awareness arises directly from some part of your circuitry. Everything about the cat in your example may happen in the brain or not and so you can't really be sure that there's an underlying reality behind it, but awareness itself is a direct consequence of the configuration of the processing equipment.
0
So what is a map and not the territory in your example? The cat identification process? The "I see a cat" quale? I am confused.
0
Yes, the cat quale is map.
0
I'd argue that it is as real as any other brain process.
0
It's real, but the thing that's being experienced isn't the real thing. The cat quale is a real process, but it's not a real cat (probably). The part of processing the quale that is the awareness (not the object of awareness) is itself the real awareness and holds the distinction of actually being in the territory rather than in the map.

What is the point of science, otherwise? Better prediction of observations? But you can't explain what an observantion is.
If the territory theory is able to explain the purpose of science, and the no-territory theory is not , the territory theory is better.
..according to a map which has "inputs from the territory" marked on it.
Well, you need to. If the territory theory can explain the very existence of observations, and the no-territory theory cannot, the territory theory is better,
Inputs from where?
No it doesn't. "The territory exists, but is not perfectly mappable" is a coherent assumption, particularly in view if the definition of the territory as the source of observations.

That depends on exactly what itis supposed to mean. Some people se it to mean that reality is not accessible outside an interpretational framework - that's a Bailey version.

I didn't interpret shminux's statement as being about realism.

Every computation requires something that instatiates it, ie a abstract or concrete machine to run on. In a very extreme case you might come up with a very abstract idea. However then the instation provider is the imaginer. Every bit of information requires a transfer of energy. Instation is transitive relation. If there is simulation of me it neccesarily instanties my thoughts too.

As a first approximation, people get what they deserve in life. Then add the random effects of luck.
Max L.
Why do Africans deserve so much less than Americans? Why did people in the past deserve so much less than current people? Why do people with poor parents deserve less than people with rich parents?
5
I count "the circumstances into which you are born" as luck. I'd guess it is the biggest component of luck, along with being struck by a disabling genetic condition or exposed to pandemic. So, the first observation has more salience in similar groups of people. So, for example, the group of people that I hang out with or work with are roughly similar enough for desert to have more salience than luck.
But perhaps that means that birth-luck should be the first approximation, then desert, then additional luck.
Max L.
6
Can you give me an example of something that is neither desert nor luck?
3
Very nice question; better, in fact than the statement to which you responded.. Examples I have in mind:
* Personal level injustice.
* Social injustice.
* How other people treat you.
But my primary point was whether things for which we are personally responsible is a bigger or lesser influence than luck. That is, if I am guessing with little knowledge, I am going to guess desert before luck for most groups with which I'd be interacting.
(Also, I am thinking that variation in luck, when the fact of variation if predictable and bad luck can be insured or mitigated, is desert, not luck.)
Particular applications might make it more clear. If you don't have a job in America, and you appear physically able to work, my first guess is that you are the biggest contributor to your unemployment. If you are unhealthy in America, and weren't born with it, my first approximation will be that you contributed mightily to your poor health. And so on.

If you fail to buy car insurance, you deserve the expected cost?
I was thinking deserving something bad meant you did something bad, not that you did something stupid.
When you say "deserve," do you mean to imply that it is terminally better for people who deserve more to get more, and people who deserve less to get less?
4
If you fail to buy auto liability insurance and cause an accident (which is entirely predictable over long periods), then my first guess is that you deserve the impoverishment that comes from the situation.
If you fail to buy uninsured motorist insurance and are in an accident that you don't cause (which is entirely predictable) and faulty driver has no insurance and can't pay (which is also entirely predictable), then my first approximation is still pretty good. It is a little off because you could be beset with e string of bad luck.
I think of it the other way around. If I see someone happy and reasonably well off, I am first going to say that they had a hand in it. If I see someone continually unhappy or impoverished (setting aside birth luck), my first guess is also going to be that they are mainly responsible for their own outcomes. Turning it round, they are usually getting what they deserve.
Whether that is better or not depends on more than individual morality, so no, I'm not saying it is better.
Also, the examples seem to have focused on material outcomes, since they are easier to talk about, but I'm also thinking of non-material things. Relationships, self-esteem, etc.
Max L.

What ethical theory are you using for your definition of "deserve"?
1
It is a fine question, since the word "deserve" is the link between an observation and a judgment about the person. I don't think I need an answer to it to make the observation that most people here don't hold that view. Which is a good thing, because I don't think I have a satisfactory answer beyond rough moral intuition.

Feminism is a good thing. Privilege is real. Scott Alexander is extremely uncharitable towards feminism over at SSC.
Yes, Yes, No. Still upvoting, because "Scott Alexander" and "uncharitable" in the same sentence does not compute.
9
I consider him a modern G.K. Chesterton. He's eloquent, intelligent, and wrong.
Do you mind telling me how you think he's being uncharitable? I agree mostly with your first two statements. (If you don't want to put it on this public forum because hot debated topic etc I'd appreciate it if you could PM; I won't take you down the 'let's argue feminism' rabbit-hole.)
(I've always wondered if there was a way to rebut him, but I don't know enough of the relevant sciences to try and construct an argument myself, except in syllogistic form. And even then, it seems his statements on feminists are correct.)
7
For a very quick example, see this Tumblr post. Mr. Alexander finds an example of a neoreactionary leader trying to be mean to a transgender woman inside the NRx sphere, and then shows the vast majority response of (non-vile) neoreactionaries to at least be less exclusionary than that, even though they have ideological issues with the diagnosis or treatment of gender dysphoria. Then he describes a feminist tumblr which develops increasingly misgendering and rude ways to describe disagreeing transgender men.
I don't know that this is actually /wrong/. All the actual facts are true, and if anything understate their relevant aspects -- if anything, I expect Ozy's understated the level of anti-transmale bigotry floating around the 'enlightened' side of Tumblr. I don't find NRx very persuasive, but there are certainly worse things that could be done than using it as a blunt "you must behave at least this well to ride" test. I don't know that feminism really needs external heroes: it's certainly a large enough group that it should be able to present internal speakers with strong and well-grounded beliefs. And I can certainly empathize with holding feminists to a higher standard than neoreactionaries hold themselves.
The problem is that it's not very charitable. Scott's the person that's /come up/ with the term "Lizardman's Constant" to describe how a certain percentage of any population will give terrible answers to really obvious questions. He's a strong advocate of steelmanning opposing viewpoints, and he's written an article about the dangers of only looking at the .
But he's looking at a viewpoint shown primarily in the <5% margin feminist tumblr, and comparing them to a circle of the more polite neoreactionaries (damning with faint praise as that might be, still significant), and, uh, I'm not sure that we should be surprised if the worst of the best said meaner things than the best of the worst.
I'm not sure he /needs/ to be charitable, again -- feminism should h

Being 5% of the group doesn't mean they are 5% of the influence. The loudest 5% may get to set the agenda of the remaining 95% if the remaining ones are willing to go along with things they don't particularly care about, but don't oppose enough to make these things deal-breakers either.

It also helps if the 5% have arguments for their positions.

According to the 2013 LW survey, the when asked their opinion of feminism, on a scale from 1 (low) to 5 (high), the mean response was 3.8 , and social justice got a 3.6. So it seems that "feminism is a good thing" is actually not a contrarian view.
If I might speculate for a moment, it might be that LW is less feminist that most places, while still having an overall pro-feminist bias.
0
If by most places you're talking about the world (or Western/American world) in general, that's pretty clearly false. The considerable majority of Americans reject the feminist label, for example. If you're talking about internet communities with well-educated members, then it probably is true.

How would you define "privilege"?
Easier difficulty setting for your life in some context through no fault or merit of your own.
7
So would you describe someone tall as having "height privilege" because they're better at basketball?
I'd argue that height privilege (up to a point, typically around 6'6") is a real thing, having nothing to do with being good at sports. There is a noted experiment, which my google-fu is currently failing to turn up, in which participants were shown a video of an interview between a man and a woman. In one group, the man was standing on a footstool behind his podium, so that he appeared markedly taller than the woman. In the other group, the man was standing in a depression behind his podium, so t that he appeared shorter. The content of the interview was identical.
Participants rated the man in the "taller" condition as more intelligent and more mature than the same man in the "shorter" condition. That's height privilege.
9
There's also a large established correlation between height and income, though not enough to completely rule out a potential common cause like "good genes" or childhood nutrition.

You really need riders to the effect that privilege of an objectionable kind is unrelated to achievement or intrinsic abilities,

This is a good definition. In particular, "Anti-oppressionists use "privilege" to describe a set of advantages (or lack of disadvantages) enjoyed by a majority group, who are usually unaware of the privilege they possess. ... A privileged person is not necessarily prejudiced (sexist, racist, etc) as an individual, but may be part of a broader pattern of *-ism even though unaware of it."
No, this is not a motte.
Why the "majority group" qualifier? Privilege has been historically associated with minorities, like aristocracy.
7
Does it have to be a majority group? For example, does this compared with this count as an example of "black privilege"? Would you describe the fact that some people are smarter (or stronger) than others as "intelligence privilege" (or "strength privilege")?
5
That's in the bailey, because of "enjoyed by a majority group."
4
Why focus only specific majority groups and thereby ignore things like men in domestic violence issues getting a lot less help from society than women?
Nearly everyone has some advantages and disadvantages. It's often not helpful to conflate that huge back of advantages and disadvantages into a single variable.
4
Like a few others, I agree with the first two but emphatically disagree with the last. And if you were right about it, I'd expect Ozy to have taken Scott to task about it, and him to have admitted to being somewhat wrong and updated on it.
EDIT: This has, in fact, happened.
6
See this tumblr post for an example of Ozy expressing dissatisfaction with Scott's lack of charity in his analysis of SJ (specifically in the "Words, Words, Words" post). My impression is that this is a fairly regular occurrence.
You might be right about him not having updated. If anything it seems that his updates on the earlier superweapons discussion have been reverted. I'm not sure I've seen anything comparably charitable from him on the subject since. I don't follow his thoughts on feminism particularly closely, so I could easily be wrong (and would be glad to find I'm wrong here).
5
OK, those things have indeed happened, to some degree. Above comment corrected.
I still don't understand what is uncharitable about the Wordsx3 post specifically. It accurately describes the behavior of a number of people I know (as in, have met, in person, and interacted with socially, in several cases extensively in a friendly manner), and I have no reason to consider them weak examples of feminist advocacy and every reason to consider typical (their demographics match the stereotype). I have carefully avoided catching the receiving end of it, because friends of mine have honestly challenged aspects of this kind of thing and been ostracized for their trouble.

Imo this quote from her response is a pretty weak argument:
"The concept of female privilege is, AFAICT, looking at the disadvantages gender-non-conforming men face, noticing that women with similar traits don’t face those disadvantages, and concluding that this is because women are advantaged in society. "
In order for this to be a sensible counterpoint you would need to either say "gender conforming male privilege" or you would need to show that there are few men who mind conforming to gender roles. I don't really see why anyone believes most men are fine with living out standard gender norms and I certainly don't see how anyone has evidence for this.
If a high percentage fo men are gender non-conforming and such men are at a disdadvantage in society then the concept of male privilege is seriously weakened. And using it is dangerous as it might harm those men to here that they are "privileged" when this is not the case (at least in terms of gender, maybe they are rich etc).

Buying a lottery ticket every now and then is not irrational. Unless you have thoroughly optimized the conversion of every dollar you own into utility-yielding investments and expenses, the exposure to large positive tail risk netted by spending a few dollars on lottery tickets can still be rational.
Phrased another way, when you buy a lottery ticket you aren't buying an investment, you're buying a possibility that is not available otherwise.
2
disagree because the cost of the possibility is too high.
1
If one lottery ticket is worth while, why not two? Are you assigning a nonlinear value to the probability of winning the lottery? That causes a number of problems.
6
At the risk of looking even more like an idiot: Buying one $1 lottery ticket earns you a tiny chance - 1 in 175,000,000 for the Powerball - of becoming absurdly wealthy. The Powerball gets as high as $590,500,000 pretax. NOT buying that one ticket gives you a chance of zero. So buying one ticket is "infinitely" better than buying no tickets. Buying more than one ticket, comparably, doesn't make a difference.
I like to play with the following scenario. A LessWrong reader buys a lottery ticket. They almost certainly don't win. They have one dollar less to donate to MIRI and because they're not wealthy they may not have enough wealth to psychologically justify donating anything to MIRI anyway. However, in at least one worldline, somewhere, they win a half a billion dollars and maybe donate $100,000,000 to MIRI. So from a global humanity perspective, buying that lottery ticket made the difference between getting FAI built and not getting it built. The one dollar spent on the ticket, in comparison, would have had a totally negligible impact.
I fully realize that the number of universes (or whatever) where the LessWrong reader wins the lottery is so small that they would be "better off" keeping their dollar according to basic economics, but the marginal utility of one extra dollar is basically zero.
edit: Digging myself in even deeper, let me attempt to simplify the argument.
You want to buy a Widget. The difference in net utility, to you, between owning a Widget and not owning a Widget is 3^3^3^3 utilons. Widgets cost $100,000,000. You have no realistic means of getting $100,000,000 through your own efforts because you are stuck in a corporate drone job and you have lots of bills and a family relying on you. So the only way you have of ever getting a Widget is by spending negligible amounts of money buying "bad" investments like lottery tickets. It is trivial to show that buying a lottery ticket is rational in this scenario: (Tiny chance) x (Absurdly, unquantifiably
4
So your utility function is nonlinear with respect to probability. You don't use expected utility. It results in certain inconsistencies. This is discussed in the article the allais paradox, but I'll give a lottery example here.
Suppose I offer you a choice between paying one dollar and getting a one in a million chance of winning $500,000, and paying two dollars and getting a one in one million chance of winning $500,000 and a one in two million chance of winning $500,001. You figure that what's basically a 0.00015% chance of winning vs. a 0.0001% chance isn't worth paying another dollar for, so you just pay the one dollar.
On the other hand, suppose I only offer you the first option, but, once you see if you've won, you get another chance. If you win, you don't really want another lottery ticket, since it's not a big deal anymore. So you buy a ticket, and if you lose, you buy another ticket. This results in a 0.0001% chance of ending up with $499,999, a 0.00005% chance of ending up with $499,998, and a 99.99985% chance of ending up with -2$. This is exactly the same set of probabilities as you had for the second option before.
No it would not. Or at least, it's highly unlikely for you to know that.
Suppose MIRI has their probability of success increased by 50 percentage points if they get a 100 million dollar donation. This means that, if 100 million people all donate a dollar, their probability of success goes up by 50 percentage points. Each successive one will change the probability by a different amount, but on average, each donation will increase the chance of success by one in 200 million. Furthermore, it's expected that the earlier donations would make a bigger difference, due to the law if diminishing returns. This means that donating one dollar improves MIRI's probability of success by more than one in 200 million, and is therefore better than getting a one in 100 million chance of donating 100 million dollars.
Even if MIRI does end up needing a mini
3
You're looking at the (potential) benefits and ignoring the costs. The costs are not negligible: "Thirteen percent of US citizens play the lottery every week. The average household spends around $540 annually on lotteries and poor households spend considerably more than the average." (source).
Buying a second ticket doubles your chances, obviously.
For each timeline where you buy a lottery ticket there is one where you don't. Under MWI you don't make any choices -- you choose everything, always.
You've never been poor, have you? :-/
It is just as trivial to show that you should spend all your disposable income and maybe more on lottery tickets in this scenario.
2
I'm only commenting to the rationality of one individual buying one ticket, not the ethics of the existence of lotteries.
Buying one ticket takes you from zero to one, buying two tickets takes you from one to two. 1/0 = infinity, 2/1 = 2. Buying anything more than 1 ticket has sharply diminishing utility. I realize this is a somewhat silly line of argument, so I'm not going to sink any more energy defending it.
I don't think we understand each other on this point. I was referring not to choosing, just winning. And the measure of the winning universes is a tiny fraction of all universes. But that doesn't matter when the utility of winning is sufficiently large. And the chance of a given individual buying a ticket isn't 50% in any meaningful quantum-mechanical sense, so "For each timeline where you buy a lottery ticket there is one where you don't" isn't true.
No, and I wouldn't recommend that a poor person buy lottery tickets. My original claim was that buying lottery tickets can be rational, not that it is rational in the general case.
That's true. People also say that you should donate all your disposable income to MIRI, or to efficient charities, for exactly the same reasons, and I don't do those things for the same reason that I don't spend all my money on lottery tickets - I'm a human. My line of argument only applies when you want a Widget and have no other way of affording it.
I don't really feel strongly enough about this to continue defending it, it's just that I'm quite sure I'm right in the details of my argument and would welcome an argument that actually changes my mind / convinces me I'm wrong.
3
I treat buying lottery tickets as buying a license to daydream. Once you realize you don't need a license for that... :-)
2
There are ways to win a lottery without buying a ticket. For example, someone may buy you a ticket as a present, without your knowledge, which then wins.
No, it is much more likely that you'll win the lottery by buying tickets than by not buying tickets (assuming it's unlikely to be gifted a ticket), but the cost of being gifted a ticket is zero, which makes not buying tickets an "infinitely" better return on investment.
1
I agree with the first sentence, but I'm not sure if our reasoning is the same. Here's mine: If humans were perfectly rational overall, buying a lottery ticket would never make sense. But we aren't. I think it's rational to buy a lottery ticket say, every six months, and then not check if it's a winner for the six months. Just as humans seems to enjoy the anticipation of an upcoming vacation more than the actual vacation, the human brain can get utility from the hope that ticket might be a winner, and 6 months of an (irrational, but so what?) hope far outweigh the one day of disappointment and one dollar lost when you check the ticket and it hasn't won.

I totally agree with this reasoning, but I don't think "fun" is the only good reason to buy a ticket.

I'd agree that if a lottery ticket and a chocolate bar give you the same hedons and no other options are available, you are better off buying a piece of paper than an unhealthy snack.
0
I'll put this here because I wish to provide a different perspective without getting bogged down in probabilistic thinking. To say buying a lottery ticket is irrational might be correct if you consider winning the lottery or not to be the only real outcome of such a purchase. The fact is, however, that buying a lottery ticket provides entertainment. You pay a relatively small sum of money to play, until results day, with the fantasy of receiving an enormous amount of money. Entertainment is utility, as far as I'm concerned. Obviously the more money you spend on the lottery, the less justifiable this entertainment is, because as others have pointed out, buying a small number of more tickets doesn't appreciably change the probability of winning. Just one ticket, however, and you're one stroke of luck away from enormous wealth; the enjoyment of knowing that alone can be worth a dollar.

Exactly what is repugnant about utilitarianism?
It's inhuman, totalitarian slavery.
Islam and Christianity are big on slavery, but it's mainly a finite list of do's and don'ts from a Celestial Psychopath. Obey those, and you can go to a movie. Take a nap. The subjugation is grotesque, but it has an end, at least in this life.
Not so with utilitarianism. The world is a big machine that produces utility, and your job is to be a cog in that machine. Your utility is 1 seven billionth of the equation - which rounds to zero. It is your duty in life to chug and chug and chug like a good little cog without any preferential treatment from you, for you or anyone else you actually care about, all through your days without let.
And that's only if you don't better serve the Great Utilonizer ground into a human paste to fuel the machine.
A cog, or fuel. Toil without relent, or harvest my organs? Which is less of a horror?

Many moral systems take one of these as fundamental (#1 for consequentialist systems, #2 for deontological systems, #3 for virtue ethics) but in practice you are going to be interested in answers to all of them, and the actual choices you need to make are between actions, not between possible worlds or characters.
Suppose you have a system for answering question 1, and on a given occasion you need to decide what to do. One way to do this is by choosing the action that produces the best possible world (making whatever assumptions about the future you need to), but it isn't the only way. There is no inconsistency in saying "Doing X will lead to a better world, but I care about my own happiness as well as about optimizing the world so I'm going to do Y instead"; that just means that you care about other things besides morality. Which pr...
Lots to comment on here. That last paragraph certainly merits some comment.
Yes, most people are almost entirely inconsistent about the morality they profess to believe. At least in the "civilized world". I get the impression of more widespread fervent and sincere beliefs in the less civilized world.
Do Christians in the US really believe all their rather wacky professions of faith? Or even the most tame, basic professions of faith? Very very few, I think. There are Christians who really believe, and I tend to like them, despite the wackiness. Honest, consistent, earnest people appeal to me.
For the great mass, I increasingly think they just make talking noises appropriate to their tribe. It's not that they lie, it's more that correspondence to reality is so far down the list of motivations, or even evaluations, that it's not relevant to the noises that come from their mouths.
It's the great mass of people who seem to instinctively say whatever is socially advantageous in their tribe that give be the heebie jeebies. They are completely alien - which, given the relative numbers, means I am totally alien. A stranger in a strange land.

I'm repeating myself here, but: I think you are mixing up two things: utilitarianism versus other systems, and singleminded caring about nothing but morality versus not. It is the latter that generates attitudes and behaviour and outcomes that you find so horrible, not the former.
You are of course at liberty to say that the term "utilitarian" should only be applied to a person who not only holds that the way to answer moral questions is by something like comparison of net utility, but also acts consistently and singlemindedly to maximize net utility as they conceive it. The consequence, of course, will be that in your view there are no utilitarians and that anyone who identifies as a utilitarian is a hypocrite. Personally, I find that just as unhelpful a use of language as some theists' insistence that "atheist" can only mean someone who is absolutely 100% certain, without the tiniest room for doubt, that there is no god. It feels like a tactical definition whose main purpose is to put other people in the wrong even before any substantive discussion of their opinions and actions begins.
It's both. (Just as a literal purchase may be both at great cost, and of great benefit.) Which is one reason why, if this person -- or someone who feels and acts similarly on the basis of utilitarian rather than religious ethics -- acts in this way because they genuinely think it's the best thing to do, then I don't think it's appropriate to complain about how grotesquely subjugated they are.
What do you believe my code to be, and why?

Under utilitarianism, human farming for research purposes and organ harvesting would be justified if it benefited enough future persons.
Under utilitarianism the ideal life is one spent barely subsisting while giving away all material wealth to effective altruism/charity. (reason being - unless you are barely subsisting, there is someone who would benefit from your wealth more than you).
Also there is no way to compare interpersonal utility. There is a sense in which I might prefer A to B, but there is no sense in which I can prefer A more than you prefer B. We could vote, or bid money but neither of these results in a satisfactory ethical theory.
0
Perhaps not with utility theory's usual definition of "prefer", but in practice there is a commonsense way in which I can prefer A more than you prefer B, since we're both humans with almost identical brain architecture.
0
Interesting, so your utilitarianism depends on agents having similar minds, it doesn't try to a be a universal ethical theory for sapient beings.
What exactly is that way in which you can prefer something more than I can? It is not common sense to me, unless you are talking about hedonic utilitarianism. Are you using intensity of desire or intensity of satisfaction as a criteria? Neither one seems satisfactory. People's preferences do not always (or even mostly) align with either. I suppose what I'm asking is for you to provide a systematic way of comparing interpersonal utility.
1
If I say "I prefer not to be tortured more than you prefer a popsicle", any sane human would agree. This is the commonsense way in which utility can be compared between humans. Of course, it isn't perfect, but we could easily imagine ways to make it better, say by running some regression algorithms on brain-scans of humans desiring popsicles and humans desiring not-to-be-tortured, and extrapolating to other human minds. (That would still be imperfect, but we can make it arbitrarily good.)
This isn't just necessary if you're a utilitarian, it's necessary if your moral system in any way involves tradeoffs between humans' preferences, i.e. it's necessary for pretty much every human who's ever lived.
0
So you are a hedonic utilitarian? You think that morality can be reduced to intensity of desire? I already pointed out that human preferences do not reduce to intensity of desire.
0
I'm not any sort of utilitarian, and that has nothing to do with my point, which is that there obviously is a sense in which I can prefer A more than you prefer B.

that's more like being conditional that we cooperate. If my enemy would say that I could find it offensive and it doesn'ty compel me to change my actions. If you try to use utlitarian theory to (en)force a cooperation the argument doesn't go throught.
AI boxing will work.
EDIT: Used to be "AI boxing can work." My intent was to contradict the common LW positions that AI boxing is either (1) a logical impossibility, or (2) more difficult or more likely to fail than FAI.
8
"Can" is a very weak claim. With what probability will it work?
1
It seems unlikely that the first people to build fooming AGI will box it sufficiently thoughtfully.
I think it's likely to work if implemented very carefully by the first people to build AGI. For instance, if they were careful, a team of 100 people could manually watch everything the AI thinks, stopping its execution after every step and spending a year poring over its thoughts. With lots of fail-safes, with people assigned to watch researchers in case they try anything, with several nested layers of people watching so that if the AI infects an inner layer of people, an outer layer can just pull a lever and kill them all, etc. And with the AI inside several layers of simulated realities, so that if it does bad things in an inner layer we just kill it, and so on. Plus a thousand other precautions that we can think up if we have a couple centuries. Basically, there are asymmetries such that a little bit of human effort can make it astronomically more difficult for an AI to escape. But it seems likely that we won't take advantage of all these asymmetries, especially if e.g. there's something like an arms race.
(See also this, which details several ways to box AIs.)

Seems like an ad hominum attack. Why wouldn't the people working on this be aware of the issues? My contrarian point is that people concerned about FAI should be working on AI boxing instead.

It would be of significant advantage to the world if most people started living on houseboats.

Is there even enough coast for that?
If people didn't live in cities, they'd have to commute more. There would be a large increase in transportation costs.
0
Where I live there is an abundance of canals. "Most people" is perhaps an exaggeration, but the main points in defence of increased houseboating would be:
(1) a house is a large, expensive, immobile and illiquid asset. A houseboat is rather less expensive, which frees up capital for other purposes.
(2) the internet makes it less necessary for most people to live in cities.
(3) there would be less costs associated with moving between different areas.
6
I find it difficult to believe that houseboats are inherently less expensive. It seems more likely that there's some reason house boats cannot be made as large and expensive as regular houses, so the average houseboat is much cheaper than the average house, even if it's more expensive than a house of the same quality.
The internet gets much more difficult if you don't live in cities. While it mitigates the costs of people not living near each other, it does not remove them. There are still lots of people putting large amounts of time into physically commuting.
Why not use mobile homes? They can't be stacked in three dimensions like apartments, but at least you can put them in two-dimensional grids.

There certainly are houseboats much larger and more expensive than regular houses.

Your link is broken. I'm not sure the proper way to fix it, but it's hard to have links to pages with end parentheses in them.

Whoops. Fixed.

Motor homes might well make more sense for this. The reason I came to this view is that I like canals and so houseboating seemed like a pleasant idea; at around the same time, I read this NY Times piece suggesting that home ownership is not necessarily a good thing. Houseboating seemed like a way of dealing with that; motorhomes simply didn't occur to me as a (probably better) alternative.
2
Your mileage may vary. Getting internet made me yearn to move to a larger city where I could meet more interesting people and do more interesting stuff---which in the end I did.

If you don't want much cost of moving you can simply rent a flat.

I am pretty sure that out of two equivalent houses the one which floats would be noticeably more expensive, and more expensive to maintain, too. Houseboats are typically less expensive than houses because they are smaller and less convenient.

Indeed. I would in principle be willing to apply a similar argument to RVs, but (since living in an RV holds no aesthetic appeal for me, whereas houseboating does) I am rather less aware of what the logistics would be like.

Having political beliefs is silly. Movements like neoreaction or libertarianism or whatever will succeed or fail mostly independently of whether their claims are true. Lies aren't threatened by the truth per se, they're threatened by more virulent lies and more virulent truths. Various political beliefs, while fascinating and perhaps true, are unimportant and worthless.
Arguing for or against various political beliefs functions mostly (1) to signal intelligence or allegiance or whatever, and (2) as mental masturbation, like playing Scrabble. "I want to improve politics" is just a thin veil that system 2 throws over system 1's urges to achieve (1) and (2).
If you actually think that improving politics is a productive thing to do, your best bet is probably something like "ensure more salt gets iodized so people will be smarter", or "build an FAI to govern us". But those options don't sound nearly as fun as writing political screeds.
(While "politics is the mind-killer" is LW canon, "believing political things is stupid" seems less widely-held.)
6
While I mostly agree, trying to devise political systems that would encourage a smarter populace (ex. SSC's Graduation Speech with the guaranteed universal income and abolishing public schools) seems like a potentially worthwhile enterprise.

I agree that forming political beliefs is not a productive use of my time in the same way that earning a salary to donate to SCI to cure people of parasites is. I disagree that this makes it silly. The reasons you gave may not be the most noble of reasons, but they are still perfectly valid.

Fossil fuels will remain the dominant source of energy until we build something much smarter than ourselves. Efforts spent on alternative energy sources are enormously inefficient and mostly pointless.
Related claim: the average STEM-type person has no gut-level grasp of the quantity of energy consumed by the economy and this leads to popular utopian claims about alternative energy.

It isn't very hard to do a little digging here. http://en.wikipedia.org/wiki/Electricity_generation#mediaviewer/File:Annual_electricity_net_generation_in_the_world.svg
China's aggressive nuclear strategy seems reasonable.
7
Not exactly sure what you mean by "digging." I already comprehend the quantities of energy being consumed because of my education and experience in related fields, it's the average person who I think does not, since I hear them saying things about how a small increase in solar panel efficiency is going to completely and rapidly "cure us of our fossil fuel addiction."
Also, your figure only reflects electricity generation, not total energy consumption which is a much higher figure. Currently non-hydrocarbon fuel sources for transportation is very fringe.
The truth is that the price of fossil fuels has always and will continue to fluctuate in accord with simple supply-demand economics for a long time to come; the cheaper it gets to make energy via alternative methods, the cheaper fossil fuels will become to undercut those alternative sources.

I looked through the numbers and the trend line. I updated in your direction. Even nuclear can't make a big dent without true mass production of reactors, which almost certainly will not happen.
2
I give it well over 70 percent chance of happening. Mostly because I am expecting coal and gas to get really unpleasantly expensive in the next two decades. The remaining 30 percent is mostly taken up by "Technological surprise rendering all extant generation tech obsolete. One of the small-scale fusion plants working out very well, for example.
-1
The only reason they have been getting expensive at all is that governments have been over-regulating them.
5
If you don't regulate them you don't pay directly but pay in medical cost for conditions such as asthma. You also get lower children IQ which is worth something. According to the EPA calculations the children IQ is worth more than the increased monetary cost of coal plants due to mercury regulation.
5
Ehrr.. Just No. Nuclear might be able to make that case, tough mostly the problem there is sticking with over-grown submarine reactors (pwr's are an asinine choice for use on land) but coal and gas? Those are, if anything underregulated due to excessive political clout. Fossil fuels will get more costly for straightforward reasons of supply and demand. The third world is industrializing, and the first world is going to use ever more electricity due to very predictable changes like the coming switch to all-electric motoring (Which, again, will not be driven by government policy, but by better batteries making the combustion engine a strictly inferior technology for cars) Thus, world wide electricity demand is going to go up. By a lot. That, in turn is going to bid up sea-borne coal and liquified natural gas to ridiculous heights because there just isn't any way to increase the supply to match. Very shortly after that, Resistance to more reactors is going to keel over and die - high electricity costs to industry being entirely unacceptable to people with lots of political clout and lots of media ownership, and suddenly mass-production is going to be on the menu. Hopefully of more sensible designs. Molten salt, molten lead, even sodium. Any design that doesn't require the power to be on for shut-down cooling to work, basically.

Unfortunately it is not quite this simple. The current oil price is on the order of $100 per barrel, but it never broke $40 per barrel prior to 1998. See figure. Also see this figure which is in terms of inflation-adjusted dollars, and shows another huge spike around 1980. The reason for these tremendous spike in price isn't simple supply-demand - complex nonlinear political factors are almost certainly to blame, and price stickiness is partially why oil remains as expensive as it is. It doesn't cost even in the ballpark of $100 per barrel to get oil out of the ground and it won't for a very very long time. The upshot is that the price of oil will continue to beat out other sources of energy by just enough to keep those sources of energy at a marginal level of profitability, because oil (and other fossil fuels) can remain profitable at much lower prices.
I would also point out that the scenario you have just described is highly complex and conjunctive, while "oil continues to do what it has been doing" is an intrinsically simple hypothesis.
3[anonymous]
Price is set on the margins. The marginal barrels of oil coming out of the ground are certainly in the ballpark of $100, from various shale and tight deposits.
1
The oil prices do not play by the economics textbook rules because most of the world's oil production is controlled by governments and governments have a variety of interests and incentives beyond what a profit-maximizing purely economic agent might have.
1
Oil is nearly utterly irrelevant to electricity, however. Nobody sane produces electricity on anything but the most minor of scales using it, and given mass-market electric cars, it is never going to be able to compete on price with electricity. charging a 100 kwh battery pack from bone dry to full would cost an average of 12 dollars and change in the US. That is the equivalent of a gas price of <60 cents per gallon, and electric cars are a better driving experience. (well, a car with a 100 kwh battery back certainly will be. That's a lot of oomp.) The sauds aren't going to be able to beat this transition just by dropping the price of oil for a year or two, nor are price hikes on the electric side going to do it - most of the cost of electricity to private consumers is taxes, so even quite large rises in the cost of coal and gas will not translate one-to-one as end-customer pain, and the differential in price is simply to large. More importantly, the electrification of the world continues apace, and most of the places joining the age of the electron do not have vast coal reserves of their own. The secular pressure to go nuclear is only going to rise, and most of the world is well beyond the reach of the various groups dedicated to the defense of helpless Actinides.
1
At the moment. But your scenario assumes that most of transportation switches its energy source from petrol/diesel to electricity. That implies that the demand for oil will drop through the floor. And that implies that oil will become very cheap. Which in turn implies that it will again start to make sense to burn it to make electricity to recharge the car batteries.
Remember that electricity is not a source of energy. To support your case for nuclear you need to show that coal and hydrocarbons will be unable to support the energy needs of the humanity in the near future. Whether cars run directly on hydrocarbons or whether there is the intermediate stage of electricity involved does not matter much for this issue.
1
Oil has uses other than automotive fuel - way before it reaches the point where it becomes competitive with coal or uranium for stationary power plants, demand from the plastics, avionics and the petrochemicals industry is going to put a floor on the price. I don't expect the saudi oil to stay under the sand, but as an energy player, the global oil industry is doomed. Coal is going to be raking in money hand over fist for a while as prices spike, but once a transition to fission starts, - and high coal prices will get that started - they are done for too. King coal only still reigns at all because the world has been collectively insane about fission due to living in the shadow of the atomic bomb.
1
Certainly true and yes, that will put a floor under the price.
That's good, isn't it? People have been pointing out for quite a while that just burning something as useful as oil is pretty silly. It also means that the world is not going to run out of oil in the foreseeable future, right?
I don't know about that -- there is an awful lot of gas around.
Do you happen to have some sort of a timetable for your predictions?
While that may be true, I don't see any signs of the world becoming more sane.

tesla says the model e is going live 2017. Average fleet turnover is 7 years and with affordable EV's on the market (I am sort of assuming at least some competition from other manufacturers here..) combustion cars become roughly as marketable as a buggy and horse, so near-total conversion to electric cars 80+ %) by 2027 - the knockon effects of that on the grid are very predictable, so a sudden dire interest in more baseload during that time period.

You DO realize that even if Tesla's wildest dreams are realized and they double the world production of lithium ion batteries, they can sell at most a few hundred thousand cars a year...

Yhea. Musk isn't breaking ground on big enough factories. That is why I am saying ten years for the switchover rather than much less than that.

Increasing the amount of lithium that get's mined each year isn't as easy of just retasking a factory to another task.

You are making a rather huge assumption that the electric battery energy density will drastically improve. Without that electric cars will still be limited to cities and commuting.
California had some significant electric shortages recently and that did NOT make them fans of building more power plants, never mind nuclear ones. If the demand spikes, high (electricity) prices will downregulate it at which point, given the cheap oil, the ICE (internal combustion engine) cars could turn out to be a sensible option :-)
2
No I'm not. I am assuming the exact batteries that are going to be coming out of the factories currently being built. Because when it comes to it, nobody is going to give a half a damn that they have to take a mid day break of thirty minutes the one time a year they visit aunt Greta three states over. Tesla is aiming at 200 mile range. At legal speeds, that is just under four hours of driving on the highway. Try and recall the last time you did more than that in one day? Now, for that trip, would a 30 minute lunch break have ruined your life?
The actual pattern of use for everyone in their day to day lives is going to be "jack the car in when you come home for the day, unplug in the morning". Total time spent; 22 seconds. This is more convenient than a weekly stop at the gas station, and vastly cheaper. At this point everyone I discuss with will bring up road trips. Except. People plan those. Including a stop at a super charger station is not a hardship. It is certainly not a hardship severe enough to justify paying 6 to ten times as much to keep your car running on a day to day basis. Is avoiding those semiannual 30 minute pitstops really worth 4 and a half thousand dollars to you? Assuming gas drops in price by half, is it worth 2250 dollars? I guarantee that avoiding them is not worth it to the average consumer. And given a sane discount rate, that difference in fuel costs means nobody is going to buy a gasoline car. You would have to give them away for free! average car turnover; 7 years. 7 x 4.5 = 31.5 thousand. The tesla E is aiming at price point of 35k. So, basically, the fuel savings are going to pay for the car. The only flaw in Elon Musks design I can spot here is that I think his planned production facilities are way to small. That provides an opening for panicked retooling for the production of "Me Too" cars from the traditional car makers. This is the main reason I said ten years for full switchover rather than 7 - most car manufacturers are currently

Y'know, that number bothered me so I decided to check. Are the annual gas expenses really $4,500?
Let's see. An average American car drives somewhere around 12,000 miles per year. A contemporary sedan running on gas goes for around 30 miles per gallon (EPA combined numbers). This means that a car burns about 400 gallons of gas per year. I filled up yesterday for $3.15 per gallon, but let's say the average current price is $3.25. 400 * $3.25 = $1,300 per year. This is the average annual gas expense.
And if you buy a small (still ICE) car, you can get gas mileage up to about 40 mpg, I think. For such a car the annual costs of gas would be below a thousand dollars.
Where does your $4,500 number come from?
0
Uhm.. That looks a heck of a lot like the reasoning I used, except I did something stupid with imperial/metric conversion, and then it didn't trigger any "That must be a mistake" bells because gas in these parts is 2 dollars.. per liter. Why can't you use metric like everyone else? ;)

No need to try, I drive long distances on a fairly regular basis.
Your estimate of half an hour for a full recharge also seems to have nothing to do with the current reality.
I trust you've heard of the typical mind fallacy? People are different. Trying to pretend everyone does the same thing isn't particularly useful.
And assuming electricity costs go up by how much? One reason gas costs so much is because it's a source of revenue for the government. Do you think the government will just forget about this revenue or maybe electric won't be so cheap after all? You are predicting a huge spike in demand, right?
LOL. OK, then, it's a simple way to become rich. Short the stocks of everyone who depends on ICE engines -- engine manufacturers, most obviously, but there's a large ecosystem around that -- and go long Tesla and its ecosystem. In ten years you should be swimming in money.
On a bit more serious note, clearly electric cars make sense for some people and some uses. They also clearly do NOT make sense for other people and other uses. Of course there will be more electric cars on the road in ten years. But there will be ICE cars as well.
0
In ten? sure. As I said, 80% penetration. It might be higher, but that /does/ depend on better batteries than conservative forward extrapolation of trends predict. Most of them will be used, because you will be able to get a used ice car for junk value and a dollar, and then junk them the first time they have any kind of major problem.
And the government wont be able to tax the electricity to the extent they do gas - no good way to do that without being lynched because electrons are electrons. Most likely, we will wind up with.. I dunno, ridiculously high taxes on tyres?
0
So, to take the used cars out of the equation, you're saying that in 10 years no one will be producing ICE cars..? Or, to avoid absolutes, given 80% penetration and the existence of used cars, do you claim that in ten years something like 95% of cars produced will be purely electric?
I wish I shared your optimism :-/
-1
More or less. Technology transitions have reinforcing feedback loops - once the transition starts, the bottom falls out of the market for used ICE cars (the junk value and a dollar thing..) which makes new ICE cars very difficult indeed to sell. After a couple years of that, gasoline is no longer sold in nearly as many places...
It's not blind optimism - look, the oil barons currently bribing the US congress (and various european politicians..) fall into two categories; "Marginal producers" and "Funny looking/weirdly dressed foreigners". That means that once the price of oil falls to any significant extent, the political lobby for oil rapidly gets reduced to 90+% "Guys in turbans with no vote". That is an interest group which politicians will loose absolutely no sleep over burning all bridges with. So there shouldn't be any pressure from the top to keep the ICE alive artificially. That will cost revenue, yes, but it will save consumers lots of money. Which they will spend. And that will create revenue, and reduce expeditures, and again.. Being the politician that steps up and says "I know you just saved thousands of dollars that were heading down to the kingdom of sand, but I just cant stand to see a commoner with money so I'm going to slap a 3 thousand dollar surcharge on your electric bill" is a good way to end up on a literal pike. No matter how much economy speak you try to dress it up in.

Well, we'll see. In the meantime, Chevy Volt, an electric car selling for $27K (with applicable tax credits, that is, a government bribe to make you buy it) is selling rather poorly, I believe.
Heh. No, the politicians have gotten quite good at saying "Look at the shiny!" while they're rifling through you wallet..

And the united kingdoms are still happily paying the poll tax, the american war of independence never happened.
Some taxes are much more.. annoying.. to the general public than others. And in this case, what you are envisioning just can't happen. You can not collect high taxes on gasoline and electricity both - the transition is fast, not instant, and so if you do that low income people who are obliged to use gasoline will actually run out of money all-together. And riot. In theory, it is possible to stop taxing gas and start taxing electricity instead, but that is so painfully stupid an idea you wouldn't be elected dogcatcher after suggesting it.
1
Well a lot of European countries are doing just that. Or rather they have "sustainable energy" mandates, which from the consumer's point of view function as a high tax on electricity.
-2
Not high enough to make gasoline competitive with electricity on price. which is the subject under debate. Not that I'm happy about the mandates, because they have failed. The only policies that have ever worked to clean up electricity generation are dams and nukes. Barring technological breakthroughs, I fear they are the only ones that are ever going to work outside of a band near the equator where solar might eventually become sane.

Humans aren't that rational; as someone here (Yvain, I think) once mentioned, they will rent/buy houses with an extra bedroom just in case aunt Greta comes over, even though the money they'd save with a smaller house would be enough to buy a stay in a five-star hotel every time aunt Greta comes over.
Also, electric cars just aren't that cool among a large segment of the population, and social status is a major part of the reason people buy expensive-ass cars.

.. And for the irrational and moneyed segment of the population willing to blow money on cool factor for conspicuous consumption EV motoring offers total freedom of design space. The basis of an EV is a skateboard. 4 wheels on the corners with electric steering, batteries and drive by wire on top of which you can drop any chassis you care to. So, blow the money needed to get the jumbo-tron extra large battery pile, and stick any chassis you care to on top. Areo-dynamics? Who cares, it isn't like the kind of person who would ignore that price gap on the fuel side of things is going to feel the pain that their car is eating watt-hours like a house decked out in Christmas lights.

I assure you that this is not true, unless I misunderstand you.

The Finding and Development cost of a typical worthwhile shale play is $1.50/Mcf (many are even better), the current natural gas price is $3.50/Mcf. Of course there are crappy fields with higher F&D cost, and these won't be drilled until prices are high enough to justify it. In effect there is a continuum of price/barrel out there in the world and this is not what controls present day prices.

And a simple solution to this is just to copy the current-day US which does not use a lot of nuclear power and also does not sacrifice many people to the demon smog.

We have roughly doubling in solar panel efficiency every 7 years. That's not what I would call "small increase".
1
Even if solar panels were 100% efficient it would not change the overall picture very much. Solar panels are expensive and do not use space efficiently.
1
With efficiency I meant the amount you pay per kilowatt hour. It's a variable that has seen consistent doubling every 7 years over the last two decades.
Space on top of most buildings is unused and there are huge deserts that aren't used.

Does the include the subsidies many governments have been providing to solar?

Subsidies per kilowatt hour didn't raise exponentially. I'm not sure to what extend they are factored out.
Solar is also not the only form of energy that get's subventioned. In Germany we used to pay billions per year in coal subventions.

They started from zero, so it's technically super-exponential.

From what I remember, transportation's responsible for about a third of CO2 emissions, a bit less than electricity generation. (Various other sources make up the remaining third, most not involving direct energy consumption.) I'm not sure exactly how that translates to energy consumption, but given the economies of scale involved, I suspect the power grid would end up dominating total energy consumption.

Is this a claim about the choices we will make or what is possible? If 1 I can buy it as an argument that states will not be rational enough to choose better options, if 2 I think its false.
Roko's Basilisk legitimately demonstrates a problem with LW. "Rationality" that leads people to believe such absurd ideas is messed up, and 1) the presence of a significant number of people psychologically affected by the basilisk and 2) the fact that Eliezer accepts that basilisk-like ideas can be dangerous are signs that there is something wrong with the rationality practiced here.
9
My contrarian idea: Roko's basilisk is no big deal, but intolerance of making, admitting, or accepting mistakes is cultish as hell.
7
Are you sure you have pinpointed the right culprit? Why exactly "rationality"? "Zooming in" and "zooming out" would lead to potentially different conclusions. E.g. G.K.Chesterton would probably blame atheism[1]. Zooming out even more, for example, someone immersed in Eastern thought might even blame Western thought in general. Despite receiving vastly disproportionate share of media attention it was such a small part of LessWrong history and thought (by the way, is anything that any LWer ever came up with a part of LW thought?) that it seems to wrong to put the blame on LessWrong or rationality in general.
Furthermore, which would you say is better, an ability to formulate an absurd idea and then find its flaws (or, for e.g. mathematical ideas, exactly under what strange conditions they hold) or inability to formulate absurd ideas at all? Ability to come up with various absurd ideas is an unavoidable side effect of having an imagination. What is important is not to start believing it immediately, because in the history of any really new and outlandish idea at the very beginning there is an important asymmetry (which arises due to the fact that coming up with any complicated idea takes time) - an idea itself has already been invented but the good counterarguments do not yet exist (this is similar to the situation where a new species is introduced to an island where it does not have natural predators, which are introduced only later). This also applies to the moment when a new outlandish idea is introduced to your mind and you haven't heard any counterarguments by that moment, one must nevertheless exercise caution. Especially if that new idea is elegant and thought provoking whereas all counterarguments are comparatively ugly and complicated and thus might feel unsatisfactory even after you have heard them.
Was there really a significant number of people or is this just, well, an urban legend? The fact that some people are affected is not particularly surprising -
5
The quotes indicate that I'm not blaming rationality, I'm blaming something that's called rationality. You're replying as if I'm blaming real rationality, which I'm not.
Censoring substantial references to the basilisk was partly done in the name of protecting the people affected. This requires that there be a significant number of people, not just that there be the normal number of people who can be affected by any unusual idea.
His explanations have varied. The explanation you linked to is fairly innocuous; it implies that he is only banning discussion because people get harmed when thinking about it. Someone else linked a screengrab of Eliezer's original comment which implies that he banned it because it can make it easier for superintelligences to acausally blackmail us, which is very different from the one you linked.
1
Curiously, it is not necessary. For example, it would suffice that people who do the censoring overestimate the number of people that might need protection. Or consider PR explanation that I gave in another comment which similarly does not require a large number of people affected. Some other parts of your comment are also addressed there.
1
It is certainly possible that few people were affected by the Basilisk, and the people who do the censoring either overestimate the number or are just using it as an excuse. But this reflects badly on LW all by itself, and also amounts to "you cannot trust the people who do the censoring", a position which is at least as unpopular as my initial one.
2
I would guess that the dislike of censorship is not an unpopular position, whatever its motivations.
3
It's whatever makes LW different from the wider population, even the wider nerdy-western-liberal-college-educated cluster. The general population of atheists does not have problems with basilisks, and laughs them off when you describe them to them.
It also received a disproportionate amount of ex cathedra moderator action. Which things are so important to EY that he feels it necessary to intervene directly and in a massively controversial way? By their actions we can conclude that the Basilisk is much more important to the LW leadership than e.g. the illegitimate downvoting that drove danerys away.
I don't think this addresses the original argument. If these ideas are dangerous to us then we are doing something wrong. If you're saying that danger is an unavoidable cost of being able to generate interesting ideas, then the large number of other groups who seem to come up with interesting ideas without ideas that present a danger to them seems like a counterexample.
I don't know, but the LW leadership's statements seem to be grounded in the claim that there were
2
At the time the Basilisk episode happened Eliezer was a lot more active in general then when the illegitimate downvoting happened.
If you look at the self professed skeptic community there are episodes such as elevator gate.
If you go a bit further back and look at what Stalin did, I would call the ideas on which he acted dangerous.
It's pretty easy to speak about a lot of topics in a way that the people you are talking to laugh and don't take the idea seriously. A bunch of that atheist population also treats their new atheism like a religion and closes itself from alternative ideas that sound weird. For practical purposes they are religious and do have a fence against taking new ideas seriously.
2
What ideas does the general population of atheists have in common besides the lack of belief in God? And what interesting ideas can you derive from that? F.Dostoevsky (who wasn't even an atheist) seems to have thought that from this one could derive that everything is morally permitted. Maybe some atheistic ideas seemed new, interesting and outlandish in the past when there were few atheists (e.g. separation of church and state), but nowadays they are part of common sense.
No, the claim of this hypothetical Chesterton would not be that atheism creates new weird ideas. It would be that by rejecting god you lose the defense against various weird ideas ("It’s the first effect of not believing in God that you lose your common sense." - G.K.Chesterton). It is not general atheism, it is specific atheist groups. And in the history of the world, there were a lot of atheists who believed in strange things. E.g. some atheists believe in reincarnation or spiritism. Some believe that the Earth is a zoo kept by aliens. In previous times, some revolutionaries (led not by their atheism, but by other ideologies) believed that just because the social order is not god given it could be easily changed into basically anything. The hypothetical Chesterton would probably claim that had all these people closely followed church's teachings they would not have believed in these follies since the common sense provided by the traditional christianity would have prevented them. And he would probably be right. The hypthetical Chesterton would probably think that the basilisk is yet another thing in the long list of things some atheists stupidly believe.
Yes, on LessWrong the weirdness heuristic is used less than in more general atheist/skeptic community (in my previous post I have already mentioned why I think it is often useful), and it is considered bad to dismiss the idea if the only counterargument to it is that is weird. Difference in acceptance of weirdness heuristic probably comes from

XiXiDu's screenshot is damning because it indicates that Eliezer banned the Basilisk because he thought a variation on it might work, not because of either PR reasons or psychological harm.
Unless you think he was lying about that for the same reason he might want to lie about psychological harm.
1
Well, in that post by Xixidu, there is a quote by Mitchell Porter (that is approved by Eliezer) that, combined with the [reddit post] I have linked earlier, seems he was not able to provide a proof that no variation of basilisk would ever work given that there are more than one possible decision theory, including some exotic and obscure ones that are not yet invented (but who knows what will be invented in the future). Eliezer seems to think that humans minds are unable to actually rigorously follow such a decision theory strictly enough that would be required for such a concept to work. But the human ability is such a vague concept, it is not clear how one can give a formal proof.
However, it seems to me that an inability to provide a formal proof seems to be an unlikely reason to freak out. What (I guess) has happened was that this inability to provide a proof, combined with that unnamed SIAI person's nightmares (I would guess that Eliezer knows all SIAI people personally) and the fear of the aforementioned potential PR disaster might have resulted into the feeling of losing control of a situation and made him panic, thus resulting into that nervous and angry post, emphasizing the danger and need to protect some people (and leaving out cult PR reasons). This is my personal guess, I do not guarantee that it is correct.
Is an inability to actually deny a thing equivalent to a belief that negation of that belief has a positive probability? Well, logically they are somewhat similar, but these two ways to express similar ideas certainly have different connotations and leave very different impressions in the listener's mind what was the person's actual degree of belief.
(I must add that I personally do not like speculating about another person's motivations why he did what he did when I actually have no way of knowing them)
1
I think many users do not think it's a serious danger, but it's still banned here. It is IMO reasonable for outsiders to judge the community as a whole by our declared policies.
Coming up with absurd ideas is not a problem. Plenty of absurd things are posted on LW all the time. The problem is that the community took it as a genuine danger.
If EY made a bad decision at the time that he now disagreed with, surely he would have reversed it or at least dropped the ban for future posts. A huge part of what this site is all about is being able to recognize when you've made a mistake and respond appropriately. If EY is incapable of doing that then that says very bad things about everything we do here.
What's cultish as hell to me is having leaders that would wilfully deceive us. If there are some nonpublic rules under which the basilisk is being censored, what else might also be being censored?
1
Well, nobody in LW community is without flaws. People often fail (or sometimes not even try) to live up to the high standards of being a good rationalist. The problem is that in some internet forums "judging the community" somehow becomes something like "this is what LW makes you to believe, and even if they deny it, they do it only because not doing it would give them a bad image" or "they are a cult that wants you to believe in their robot god" which are such gross misrepresentations of LW (or even thedrama surrounding the basilisk stuff) that even after considering Hanlon's razor one is left wondering whether that level of misinterpretation is possible without at least some amount of intentional hostility. I would guess that nowadays a large part of annoyance at somebody even bringing this topic up is a reaction to this perceived hostility.
No, neither it says very bad things about everything we do here, nor about everything we do here. Whenever EY makes a mistake and fails to recognize and admit it, it is his personal failing to live up to the standards he wrote about so much. You may object that not enough people called him out on that on LW itself, but it was my impression that many of those that do e.g. on reddit seem to be LW users (as currently there are few related discussions here on LW, there is no context to do that here, besides, EY rarely comments here anymore). In addition to that on this thread there seems to be several LW users who agree with you, thus definitely you are not a lone voice, among LWers there seem to be many different opinions. Besides, on that reddit thread he seems to basically admit that, in fact, he did make a lot of mistakes in handling this situation.
It has just dawned to me that while we are talking about censorship, at the same time we are having this discussion. And frankly, I do not remember when was the last time a comment was deleted solely for bringing this topic up. Maybe the ban has been silently lifted or at least i

The overwhelming majority of everyone on LessWrong, now and previously, believes that The Thing is completely ridiculous and would never work at all. Last I heard, Eliezer barely gave thought to the concept that it would really work, but instead blew up at the fact that hapless, innocent readers were being very stressed out by their lack of understanding of why it can't really work.

Biological hominids descended from modern humans will be the keystone species of biomes loosely descended from farms pastures and cities optimized for symbiosis and matter/energy flow between organisms, covering large fractions of the Earth's land, for tens of millions of years. In special cases there may be sub-biomes in which non-biological energy is converted into biomass, and it is possible that human-keystone ocean-based biomes might appear as well. Living things will continue to be the driving force of non-geological activity on Earth, with hominid-driven symbiosis (of which agriculture is an inefficient first draft) producing interesting new patterns materials and ecosystems.

Are you imagining these human descendents will be technology using?

Yes, as hominids have been for more than a million years. An expanded toolkit though, even compared to today (though its possible that not all of our current tools will have the futures many of us expect, in the long run). Good manipulation of electromagnetism alone is having very interesting effects that we have only really begun to touch on, and I expect biotechnology and related things to have interesting roles to play. All of this will have to occur within the context of ecological laws which are pretty immutable, and living systems are very good at evolving and replicating and surviving in many contexts on this planet.

Reductionism as a cognitive strategy has proven useful in a number of scientific and technical disciplines. However, reductionism as a metaphysical thesis (as presented in this post) is wrong. Verging on incoherent, even. I'm specifically talking about the claim that in reality "there is only the most basic level".

Most of humanity hates deviants and I don't think there's anything incoherent about that value.
I don't think you could get enough of humanity to agree on what should be considered "deviant" to make that value cohere.

What cross-section of humanity are you familiar with?

Familiar with? Using the most obvious definition I'd say only my girlfriend.
Due to where I live I have neighbours from a wide variety of races and religions and mostly a different class from the people I grew up with, which is different again from the class I work in now. I haven't lived for any substantial time in a different country. Does that answer your question?

So you know there are these people called "hipsters" who take pride in showing off their deviance and compete with one another to be deviant in interesting and original ways, right? Do you know many of them?

And everyone loves hipsters, right? Fellow hipsters of course support each other, but the wider world has nothing but respect and admiration for these people. Satisfying everyone's values would certainly mean there were more hipsters around and that hipsters were encouraged to be even more hipster-ey.
0
Well, hipsters often like each other and they are a decently large faction. Also, I think hipsters might be disliked because they are overly intentional about being deviant ("I was in to them before they were cool" as a way to try to one-up someone, etc.)

Yet the wider world still tends to assign them high status.
2
I don't think that's true. To my eyes hipsters are this generation's nouveau riche; people who have money and some kind of status, but don't conform to upper-class tastes. The wealth and status precedes the hipsterism, it doesn't derive from it.

Well previous generations' nouveau riche had better taste.

If by "CEV" you mean the mean reflectively-consistent utility function of all living humans... then yes, this is most likely true, and I consider it a major flaw of average-utilitarianism for FAI. Why so major? Because any decent science-fiction fan can invent three ways to deal with the mutual incompatibility of some people with some other people that doesn't involve just taking an average and punishing the unusual, off the top of his head, and so can most moral theorists other than average-utilitarians.

Causal connections should not be part of our most fundamental model of the Universe. Everything that is useful about causal narratives is a consequence of the Second Law of Thermodynamics, which is irrelevant when we're talking about microscopic interactions. Extrapolating our macroscopic fascination with causation into the microscopic realm has actually impeded the exploration of promising possibilities in fundamental physics.

That would explain why it took so long for someone to discover timeless physics.
That sentence has the same air of paradox about it as "Many solipsists believe ...". (Perhaps deliberately?)
1
I confess I'm surprised by all the upvotes this one is getting. I thought it was quite a mainstream view.
1
I upvoted it because of the last sentence. Physicists are well aware that the differential equations (as opposed to the boundary conditions) of our universe are most likely CPT-invariant.
4
Yes, they are aware of this, but there are many examples of physicists failing to grasp the full significance of this fact. There is a difference between physicists acknowledging the CPT-invariance of fundamental laws, and fully embracing the philosophical consequences of this invariance. Huw Price's Time's Arrow and Archimedes' Point documents a number of cases of physicists failing to do the latter.
For further examples, see the mess of a priori causality conditions and chronology protection conjectures in GR, largely motivated by a desire to avoid "causal paradoxes". Tachyons are declared unphysical for similar reasons. So-called retrocausal interpretations of quantum mechanics, a very promising research topic IMO, are largely unexplored. Advanced (as opposed to retarded) solutions to differential equations are ruled unphysical. I could go on.
There is still a big unwritten assumption in theoretical physics that proper scientific explanations must account for things that happen now in terms of things that happened earlier. I can't think of any reason for this bias beyond an attachment to causal narratives.
3
Classical GR actually rules out changing the past (while allowing CTCs), despite the common misconceptions about it. The Novikov's self-consistency principle was self-admittedly a way to say "there is no new physics other than GR". Hawking's famous chronology protection paper mainly showed that QFT cannot be done in the standard way on a wormhole background.
They are generally "declared unphysical" because the time-travel aspects cannot be analyzed self-consistently. Plus there is little evidence for it. However, non-propagating tachyon fields are not incompatible with GR. For example, a 2+1D slice of a 3+1D Schwarzschild black hole contains induced FTL matter fields, Kaluza-Klein style. PM me if you want more details.
I can't imagine how an interpretation can be a promising research topic.
I think this is overstating it. As long as a model is capable of predicting future observations based on the current ones, it is worth considering. If not, then it's no longer a natural science, but at best math.
1
Oh, that's a good point. I wonder whether pragmatist really meant to make such a strong statement there.

Social problems are nearly impossible to solve. The methods we have developed in the hard sciences and engineering are insufficient to solve them.

Would you disagree with the claim that several significant social problems have in fact been solved over the history of human civilization, at least in parts of the world? Or are you saying that those were the low-hanging fruit and the social problems that remain are nearly impossible to solve?
What would you say about the progress that has been made towards satisfying the Millennium Development Goals?
3
Looking at the list, I would say that to the extent progress has been made towards them (and to the extent they're worthy goals, the "sustainable development" one is trying to solve the wrong problem and the "gender equality" one is just incoherent) it is incidental to the efforts of the UN.

Yvain seems to agree.
4
The problem with Yvain's argument is that it appears to be an example of the PHB fallacy "anything I don't understand is easy to do". Or rather the "a little knowledge" problem "anything I sort of understand is easy to do".
During the Enlightenment, when people first started talking about reorganizing society on a large scale, it seemed like a panacea. Now that we have several centuries extremely messy experience with it, we know that it's harder than it at first appeared and there are many complications. Now that developments in biology seem to make it possible to make changes to biology it again looks like a panacea (at least to the people who haven't learned the lessons of the previous failure). And just as before, I predict people will discover that it's a lot more complicated, probably just a messily.
English has a pronoun that can be used for either gender and, as an accident of history not some hidden agenda, said pronoun in English is "he/him/&c."
Edited: VAuroch is the best kind of correct on "neuter" pronouns. Changed, though that might make a view less controversial than I thought (all but 2 readers agree, really?) even less so :)
6
I consider this an incoherent claim. "A neuter pronoun", inherently, is one that can be applied to individuals regardless of gender (actual or grammatical). That's what people want when they wish English had a neuter pronoun. 'He/him/his' is not such a pronoun. "They/them/their" is.
7
Nope. "Of all the men and women here, one will prove his worth" is grammatical and does not imply a man IMO. I'm not defining myself right of course, just clarifying why my contrarian claim is coherent.
3
That was historically true, but many women and nonbinary people disagree with the statement that it is still true. And it was never neuter; it used to be the case that using male pronouns for an unspecified person was grammatically valid.

You are exactly right on technical use of "neuter." Fixed, and thank you.
What is a nonbinary person in the sense you are using it, apart from a subset of non-women? I can't get use from context. Just for curiosity, and probably off topic so pm if exactly one person cares.
If I thought everybody agreed it wouldn't be contrarian now would it?
3
Nonbinary people consider themselves neither male nor female, both male and female, male and female individually but at different times, or any other vector combination of genders besides {1,0} and {0,1}; naturally, they are all transgender. They're fairly uncommon, largely because the idea that identifying as nonbinary is not available to the vast majority of people and would be stigmatized if they did choose to adopt it.

Singular "they" existed but then it waned out of use. It has seen some comebacks. If gender information would not be criticfal it woudl have been "he" that would ahve vaned. It might not be a hidden agenda but more like ununderstood or emergent derived agenda.

Artificial intelligences are overrated as a threat, and institutional intelligences are underrated.
6
Overrated in LessWrong, or globally? I upvoted assuming the former, although I agree that institutional intelligences are an underrated threat.
1[anonymous]
I intended the former. I'm not sure if it would make sense to say it's the case globally: certain institutional intelligences are sometimes taken as threats (see: the global warming debate), but there isn't really a theory, or even a widespread concept, of institutional intelligences in general. (My suspicion is that it was worked out to some extent in the '30s, and then WW2 went the way it did and the Cold War came around and all that made it seriously unfashionable.)
The universe we perceive is probably a simulation of a more complex Universe. In breaking with the simulation hypothesis, however, the simulation is not originated by humans. Instead, our existence is simply an emergent property of the physics (and stochasticity) of the simulation.
1
Why? This looks as if you're taking a hammer to Ockham's razor.
1
In the strictest sense, yes I am. I design, build and test social models for a living (so this may simply be a case of me holding Maslow's Hammer). The universe exhibits a number of physical properties which resemble modeling assumptions. For example, speed is absolutely bounded at c. If I were designing an actual universe (not a model), I wouldn't enforce upper bounds--what purpose would they serve? If I were designing a model, however, boundaries of this sort would be critical to reducing the complexity of the model universe to the realm of tractable computability.
On any given day, I'll instantiate thousands of models. Having many models running in parallel is useful! We observe one universe, but if there's a non-zero probability that the universe is a model of something else (a possibility which Ockham's Razor certainly doesn't refute), the fact that I generate so many models is indicative of the possibility that a super-universal process or entity may be doing the same thing, of which our universe is one instance.
2
I do think its useful to use what we know about simulations to inform whether or not we live in one. As I said in my other comment, I don't think a finite speed of light, etc., says much either way, but I do want to note a few things that I think would be suggestive.
If time was discrete and the time step appeared to be a function of known time step limits (e.g., the CFL condition), I would consider that to be good evidence in favor of the simulation hypothesis.
The jury is still out whether time is discrete, so we can't evaluate the second necessary condition. If time were discrete, this would be interesting and could be evidence for the simulation hypothesis, but it'd be pretty weak. You'd need something further that indicates something how the algorithm, like the time step limit, to make a stronger conclusion.
Another possibility is if some conservation principle were violated in a way that would reduce computational complexity. In the water sprinkler simulations I've run, droplets are removed from the simulation when their size drops below a certain (arbitrary) limit as these droplets have little impact on the physics, and mostly serve to slow down the computation. Strictly speaking, this violates conservation of mass. I haven't seen anything like this in physics, but its existence could be evidence for the simulation hypothesis.

This is not true in general. I've considered a similar idea before, but as a reason to believe we don't live in a simulation (not that I think this is a very convincing argument). I work in computational fluid dynamics. "Low-Mach"/incompressible fluid simulations where the speed of sound is assumed infinite are much more easily tractable than the same situation run on a "high Mach" code, even if the actual fluid speeds are very subsonic. The difference of running time is at least an order of magnitude.
To be fair, it can go either way. The speed of the fluid is not "absolutely bounded" in these simulations. These simulations are not relativistic, and treating them as that would make things more complicated. The speed of acoustic waves, however, is treated infinite in the low Mach limit. I imagine there are situations in other branches of mathematical physics where treating a speed as infinite (as in the case of acoustic waves) or zero (as in the non-relativistic case) simplifies certain situations. In the end, it seems like a wash to me, and this offers little evidence in favor or against the simulation hypothesis.
1
Huh. It never occurred to me that imposing finite bounds might increase the complexity of a simulation, but I can see how that could be true for physical models. Is the assumption you're making in the Low Mach/incompressible fluid models that the speed of sound is explicitly infinite, or is it that the speed of sound lacks an upper bound? (i.e., is there a point in the code where you have to declare something like "sound.speed = infinity"?)
Anyway, I've certainly never encountered any such situation in models of social systems. I'll keep an eye out for it now. Thanks for sharing!

As a trivial point, imposing finite bounds means that you can't use the normal distribution, for example :-)
0
Not true: it means you shouldn't use a normal distribution, and when you do you should say so up front. I see no reason not to apply normal distributions if your limit is high (say, greater than 4 sigmas--social science is much fuzzier than physical science). Better yet, make your limit a function of the number of observations you have. As the probability of getting into the long tail gets higher, make the tail longer.
1
Truncated normal is not the same thing as a plain-vanilla normal. And using it does mean increasing the complexity of the simulation.
0
Sentence 1: True, fair point. Sentence 2: This isn't obvious to me. Selecting random values from a truncated normal distribution is (slightly) more complex than, say, a uniform distribution over the same range, but it is demonstrably (slightly) less complex than selecting random values from an unbounded normal distribution. Without finite boundaries, you'd need infinite precision arithmetic just to draw a value.
0
The problem is not with value selection, the problem is with model manipulation. The normal distribution is very well-studied, it has a number of appealing properties which make working with it rather convenient, there is a lot of code written to work with it, etc. Replace it with a truncated normal and suddenly a lot of things break.

Oh! I see what you're saying. Definitely can't argue with that.

Glad you found my post interesting. I found yours interesting as well, as I thought I was the only one who made any argument along those lines.
There's no explicit step where you say the speed of sound is infinite. That's just the net effect of how you model the pressure field. In reality, the pressure comes from thermodynamics at some level. In the low-Mach/incompressible model, the pressure only exists to enforce mass conservation, and in some sense is "junk" (though still compares favorably against exact solutions). Basically, you do some math to decouple the thermodynamic and "fluctuating" pressure (this is really the only change; the remainder are implications of the change). You end up with a Poisson equation for ("fluctuating") pressure, and this equation lacks the ability to take into account finite pressure/acoustic wave speeds. The wave speed is effectively infinite.
To be honest, I need to read papers like this to gain a fuller appreciation of all the implications of this approximation. But what I describe is accurate if lacking in some of the details.
In some ways, this does make things more complicated (pressure boundary conditions being one area). But in terms of speed, it's a huge benefit.
Here's another example from my field: thermal radiation modeling. If you use ray tracing (like 3D rendering) then it's often practical to assume that the speed of light is infinite, because it basically is relative to the other processes you are looking at. The "speed" of heat conduction, for example, is much slower. If you used a finite wave speed for the rays then things would be much slower.
0
That makes a lot of sense. I asked about explicit declaration versus implicit assumption because assumptions of this sort do exist in social models. They're just treated as unmodeled characteristics either of agents or of reality. We can make these assumptions because they either don't inform the phenomenon we're investigating (e.g. infinite ammunition can be implicitly assumed in an agent-based model of battlefield medic behavior because we're not interested in the draw-down or conclusion of the battle in the absence of a decisive victory) or the model's purpose is to investigate relationships within a plausible range (which sounds like your use case). That said, I'm very curious about the existence of models for which explicitly setting a boundary of infinity can reduce computational complexity. It seems like such a thing is either provably possible or (more likely) provably impossible. Know of anything like that?
1
I see your distinction now. That is a good classification.
To go back to the low-Mach/incompressible flow model, I have seen series expansions in terms of the Mach number applied to (subsets of) the fluid flow equations, and the low-Mach approximation is found by setting the Mach number to zero. (Ma = v / c, so if c, the speed of sound, approaches infinity, then Ma goes to 0.) So it seems that you can go the other direction to derive equations starting with the goal of modeling a low-Mach flow, but that's not typically what I see. There's no "Mach number dial" in the original equations, so you basically have to modify the equations in some way to see what changes as the Mach number goes to zero.
For this entire class of problems, even if there were a "Mach number dial", you wouldn't recover the nice mathematical features you want for speed by setting the Mach number to zero in a code that can handle high Mach physics. So, for fluid flow simulations, I don't think an explicit declaration of infinite sound speed reducing computational time is possible.
From the perspective of someone in a fluid-flow simulation (if such a thing is possible), however, I don't think the explicit-implicit classification matters. For all someone inside the simulation knows, the model (their "reality") explicitly uses an infinite acoustic wave speed. This person might falsely conclude that they don't live in a simulation because their speed of sound appears to be infinite.
0
Btrettel's example of ray tracing in thermal radiation is such a model. Another example from social science: basic economic and game theory often assume the agents are omniscient or nearly omniscient.
0
False: Assuming something is infinite (unbounded) is not the same as coercing it to a representation of infinity. Neither of those examples when represented in code would require a declaration that thing=infinity. That aside, game theory often assumes players have unbounded computational resources and a perfect understanding of the game, but never omniscience.
0
A better term is "logical omniscience".
There are some I hold:
- 1: evolution isn't inherently slow. Sometimes/often it can be faster than any other known method.
- 2: thinking is nothing but evolutionary process in our heads. No really deep secrets here to be uncovered.
- 3: from 1 and 2 a really near Singularity is possible, but not mandatory
- 4: the infinity is not even a coherent concept
- 5: there are no aliens nearby, life is rare (but this is not a contrarian position anymore)
- 6: Venus is hot due to volcanoes
- 7: Mother Nature is a stupid bitch. Some species - like wild dogs of Africa - make everything even worse
- 8: the Universe is not only to conquer, but to re-shape completely
- 9: Rome was magnificent, Carthage was not
- 10: the Relativity isn't coherent either
These are 10 different propositions. Fortunately I disagree with most of them so can upvote the whole bag with a clear conscience, but it would be better for this if you separated them out.

I agree with this meta-comment. Should I downvote it?

Care to explain this one?
0
Yes.
A big pie, rotating in the sky, should have apparently shorter circumference than a non-rotating one, and both with the same radii.
I can't swallow this. Not because it is weird, but because it is inconsistent.
8
There is no inconsistency. In one case you are measuring the circumference with moving rulers, while in the other case you are measuring the circumference with stationary rulers. It's not inconsistent for these two different measurements to give different results.
-1
No. I am measuring from here, from the centre with some measuring device.
First I measure stationary pie, then I measure the rotating one. Those red-white stripes are either constant, either they shrink. If they are shrinking, they should multiply as well. If they are not shrinking, what happened with Mr. Lorentz's contraction?
4
If you measure a wheel with a ruler, and the wheel is moving relative to the ruler, then your measurement assumes that both ends of a piece of the wheel line up with both ends of a piece of the ruler at the same time. Whether these events happen at the same time, and therefore whether this is a measurement of the wheel, are different depending on the frame of reference.
2
Why is it inconsistent?
5
Special Relativity + some basic mechanics leads to an apparent contradiction in the expected measurements, which is only resolved by introducing a curved space(time). So this would be a failure of self-consistency: the same theory leads to two different results for the same experiment.
However, the two measurements of ostensibly the same thing are done by different observers, so there is no requirement that they should agree. Introducing curved space for the rotating disk shows how to calculate distances consistently.
1
The problem is that it's inconsistent with solid-body physics?
Solid-body physics is an approximation. This isn't hard to show. Just bend something.
Consider the model of masses connected by springs. This is consistent with special relativity, and can be used to model solid-body physics. In fact, it's a more accurate model of reality than solid-body physics.
0
No, that's not the issue. The problem is that no flat-space configuration works.
0
The spacetime itself is flat (if the mass of the pie is negligible), but the spacelike slices are curved because you're slicing it in a weird way.
2
I have two photos of two different pies, one of rotating one and one of not rotating. Photos are indistinguishable, I can't tell which is which.
On the other hand, both pies have one-to-one correspondence with photos an one should be slightly deformed on the edge.
Even if it is, on the photo can't be. The photo is perfectly Euclidean. I have measured no Lorentz contraction.
5
In other news, the earth is really flat because photographs of the earth are flat.
4
Just to clarify, is the spinning pie a set of particles in the same relative position as with a still pie, but rotating around the origin? Is it a set of masses connected by springs that has reached equilibrium (none of the springs are stretching or compressing) and the whole system is spinning? Is the pie a solid body?
What exactly we're looking at depends on which of the first two you picked. If you picked the third, it is contradictory with special relativity, but there's a lot more evidence for special relativity than there is for the existence of a solid body. Granted, a sufficiently rigid body will still be inconsistent with special relativity, but all that means is that there's a maximum possible rigidity. Large objects are held together by photons, so we wouldn't expect sound to travel through them faster than light.
0
The spinning set of particles is a toroidal with let say 1 million light years across - the big R. and with the small r of just 1 centimetre. It is painted red and white, differently each metre.
The whole composition starts to slowly rotate on the signal from the centre. And slowly, very slowly accelerate to reach the speed of 0.1 c in a several million years.
Now, do we see any Lorentzian contraction due to the SR, or not due to the GR?
(Small rockets powered by radioactive decay are more than enough to compensate for the acceleration and for the centrifugal force. Both incredibly small. This is the reason why we have choose such a big scale.)
2
I'm going to assume mass is small enough not to take GR into effect.
From the point of view of a particle on the toroid, the band it's in will extend to about 1.005 meters long. Due to Lorentz contraction, from the point of reference of someone in the center, it will appear one meter long.
0
The question is ONLY for the central observer. At first he sees 1 m long stripes, but when the whole thing reaches the speed of 0.1 c, how long is each stripe?
3
One meter.
I just want to clarify. I'm assuming the particles are not connected, or are elastic enough that stretching them by a factor of 1.005 isn't a huge deal. If you tried that with solid glass, it would probably shatter.
Come to think of it, this looks like a more complicated form of Bell's spaceship paradox.
0
I think you're right, but you're interpreting “sees” literally I'm not 100% sure of that, because of light aberration (the Terrell-Penrose effect).
0
I wasn't interpreting "sees" literally, but it wouldn't make much of a difference. Since the observer is in the center of the circle, the light lag is the same everywhere. The only difference is that the circles bordering the bands will look slightly slanted, and the colors will be slightly blue-shifted.
2
Place red and white equilength rulers on the edge of the cylinder. The rotating cylinder will have more and shorther rulers. Thus the photos are not the same. Even better have the cylinder slowly pulse in different colors. The edges will pulse more slowly thus not being in synch with the center.
Related phenomenon is that moving ladders fit into garages that stationary ones would not.
0
They will multiply as the orbital speed increases? Say that Arab numerals are written on the rulers. Say that they are 77 at the beginning. Will this system know when to engage the number 78?
Or will there be two 57 at first? Or how is it going to be?
3
I was thinking of already spun cylinder and then adding the sticks by accelerating them to place.
If you had the same sticks already in place the stick would feel a stretch. If they resist this stretch they will pull apart so there will be bigger gaps between them. For separate measuring sticks they have no tensile strenght in the gaps between them. However if you had a measuring rope with continous tensile strenght and at a beginning / end point where the start would be fixed but new rope could freely be pulled from the end point you would see the numbers increase (much like waist measurements when getting fatter). However the purpoted cylinder has maximum tensile strenght anywhere continously. Thus that strenght would actually work against the rotating force making it resist rotation. a non-rigid body will rupture and start to look like a star.
So no there would not be duplicate sticks but yes the rope would know to engage number 78.
If you would fill up a rotating cylinder with sticks and spin it down the stick would press against each other crushing to a smaller lenght. A measuring rope with a small pull to accept loose rope would reel in. A non-rigid body slowing down would spit-out material in bursts that might come resemble volcanoes.

Saying that a moving ladder "fits" means that the start of the ladder is in the garage at the same time that the end of the ladder is. If the ladder is moving and contracted because of relativity, these two events are not simultaneous in all reference frames. Thus, you cannot definitely say that the moving ladder fits--whether it fits depends on your reference frame. (In another reference frame you would see the ladder longer than the garage, but you would also see the start of the ladder pass out of the garage before the end of the ladder passes into it.)
0
Why have that definition of "fit"? I could eqaully well say that fitting means that there is a reference frame that has a time where the ladder is completely inside.
If you had the carage loop back so that the end would be glued to the start you could still spin the ladder inside it. From the point of the ladder it would appear to need to pass the garage multiple times to oene fit ladder lenght but from the outside it would appear as if the ladder fits within one loop completely. With either perspective the one garage space enough to contain the ladder without collisions. In this way it most definetly fits. Usually garages are thought to be space-limited but not time limited. Thus the eating of the time-dimension is a perfectly valid way of staying within the spatial limits.
edit: actually there is a godo reazson to priviledge the rest frame oft he garage as the one that count as ragardst to fitting as then all of the fitting happens within its space and time.
0
In that case, the ladder fits.
Each rung of the ladder has a distinct reference frame. "From the point of the ladder" is meaningless.
0
If the ladder point of view is ildefined so is the garage point of view as the front and back of the garage have distinct reference frames. Any inertial reference frame is equally good. The ladder is not accelerating thus inertial. In the sense that we can talk of any frame as more than a single event or world line the ladder frame is perfectly good.
2
In the normal example, where the ladder is straight and moving forward, it has only one reference frame. Strictly speaking, each rung has a different reference frame, but they differ only by translation.
From what I understand, you modified it to a circular ladder spinning in a circular garage. In this case, each rung is moving in a different direction, and therefore at a different velocity. Thus, each rung has its own reference frame.
0
ah, I meant to glue the end and start together without curved shape/motion. But I guess that is physically unrealisable and potentially more distracting than explanatory.
2
Actually that's not a big deal. Technically you need general relativity to do that, but it's just a quotient space on special relativity. In any case, it works out exactly the same as an infinite series of ladders and garages.
There is one thing you have to be careful about. From the rest frame, the universe could be described as repeating itself every, say, ten feet. But from the point of view of the ladder, it's repeating itself every five feet and 8.8 nanoseconds. That is, if you move five feet, you'll be in the same place, but your clock will be off by 8.8 nanoseconds.
0
Actually from the point of view of the ladder the universe still repeats at every ten feet. It is just that from it's point of view it takes the space of two carages at any one instant.Both the garage and ladder are in a state of rest and show equally good times. Yes they read different but doesn't mean they are in error.
I am not sure whether it would see other instances of itself. I only spesified a spatial gluing and not that the garage be split into timeslices. I guess that the change of the point of view has changed some of that gluing to be from future to past. For if the ladder would be too long the frontend would not crash to the same ladder time backend but to a future one. (ignoring the problem of how you would try to slide the ladder into too small a hole in the first place)
1
No, it does not. I think I messed up before and it's actually 20 feet and 8.8 nanoseconds. From the the point of view of the garage, the coordinates (0 ft, 0 ns) and (10 ft, 0 ns) correspond to the same event. From the point of view of the ladder, the coordinates became (0 ft, 0 ns) and (20 ft, 8.8 ns). They still have to be the same event.
The universe is definitely repeating itself to be off by a certain time, and the distance it is off by is not ten feet.
0
The ladder sees the carage length contract. That is less than 10 feet. The ladder doesn't see itself contract that puts the limit on the repeating of the universe.
Are you sure the ladder point equivalences are not (0 ft, 0ns) and (20 ft, -8.8ns)?
1
It depends on which direction it's moving. I didn't bother to check the sign.
Thinking about it now, if it's going in the positive direction, then it should be (20 ft, -8.8ns). You are correct.
0
If the rotating pie is a pie that when nonrotating had the same radius as the other one, when it rotates it has a slightly larger radius (and circumference) because of centrifugal forces. This effect completely dominates over any relativistic one.
0
The centrifugal force can be arbitrary small. Say that we have only the outer rim of the pie, but as large as a galaxy. The centrifugal force at the half of speed of light is just negligible. Far less than all the everyday centrifugal forces we deal with.
Now say, that the rim has a zero around velocity at first and we are watching it from the centrer. Gradually, say in a million years time, it accelerates to a relativistic speed. The forces associated are a millionth of Newton per kilogram of mass. No big deal.
The problem is only this - where's the Lorentz contraction?
As long as we have only one spaceship orbiting the Galaxy, we can imagine this Lorentzian shrinking. In the case of that many, that they are all around, we can't.
2
If you have a large number of spaceships, each will notice the spaceship in front of it getting closer, and the circle of spaceships forming into an ellipse.
At least, that's assuming the spaceships have some kind of tachyon sensor to see where all the other ships are from the point of reference of the ship looking, or something like that. If they're using light to tell where all of the other ships are, then there's a few optical effects that will appear.
0
The question is what the stationary observer from the centre sees? When the galactic carousel goes around him. With the speed even quite moderate, for the observer has precise instruments to measure the Lorentzian contraction, if there is any.
At first, there is none, because the carousel isn't moving. But slowly, in many million years when it accelerate to say 0.1 c, what does the central observes sees? Contraction or no contraction?
3
He will see each spaceship contract. The distance between the centers of the spaceships will remain the same.
0
But no, those ships are just like those French TGV's. A whole composition of cars and you can't say where one ends and another begins.
It's like a snake, eating its tail!
5
Then they stretch. Or break.
0
Or they stay the same but the radius of the train as measured by the observer in the centre will shrink.
0
They mustn't. All should be smooth just like those Einstein's train. No resulting breaking force is postulated.
But everything boils down to the "a microscope which enlarges the angles"
How do you then see two perpendicular intersecting lines under that microscope?
Can't be.
This Lorentz contraction has the same fundamental problem. How it would look like?
3
The force is due to chemical bonds. They pull particles back together as their distance increases. These chemical bonds are an example of electromagnetism, which is governed by Maxwell's laws, which are conserved by Lorentz transformation.
Granted, whether a field is electric or magnetic depends on your point of reference. A still electron only produces an electric field, but a moving one produces a magnetic field as well. But if you perform the appropriate transformations, you will find that looking at a system that obeys Maxwell's laws from a different point of reference will result in a system that obeys Maxwell's laws.
In fact, Lorentz contraction was conjectured based on Maxwell's laws before there was any experimental evidence of it. Both of those occurred before Einstein formulated special relativity.
Lorentz transformation does not preserve angles Euclidean distance or angles. It preserves something called proper distance.
This is what Lorentz transformation on 1+1-dimensional spacetime looks like: https://en.wikipedia.org/wiki/Lorentz_transformation#mediaviewer/File:Lorentz_transform_of_world_line.gif. There's one dimension of space, and one of time. Each dot on the image represents an event, with a position and a time. Their movement corresponds to the changing point of reference of the observer. The slope of the diagonal lines is the speed of light, which is preserved under Lorentz transformation.
Here's my question for you: with all of the effort put into researching special relativity, if Lorentz transformation did not preserve the laws of physics, don't you think someone would have noticed?
1
Then how are you accelerating them up to c/2?
0
With a tiny force of 1 micro Newton per kilogram of mass over several million years.
This was the acceleration force.
The centrifugal force is much less.
1
This is the force that will serve as the breaking force.
0
Each piece of the ring is longer as measured by an inertial observer comoving with it than as measured by a stationary one (i.e. one comoving with the centre of the ring). But note that there's no inertial observer that's comoving with all pieces of the ring at the same time, and if you add the length of each piece as measured by an observer comoving with it what you're measuring is not a closed curve, it's a helix in spacetime. (I will draw a diagram when I have time if I remember to.)
0
The inertial observer in the centre of the carousel measures those torus segments when they are stationary.
Then, after a million years of a small acceleration of the torus and NOT the central observer, the observer should see segments contracted.
Right?
1
During the million years of small acceleration, the torus will have to stretch (i.e. each atom's distance from its neighbours, as measured in its own instantaneous inertial frame will increase) and/or break.
Specifying that you do it very slowly doesn't change anything -- suppose you and I are holding the two ends of a rope on the Arctic Circle, and we go south to the Equator each along a meridian; in order for us to do that, the rope will have to stretch or break even if we walk one millimetre per century.
-2
I don't see any reason this very big torus should break.
Forces are really tiny, for R is 10^21 m and velocity is about 10^8 m/s. That gives you 10^-5 N per kg of centrifugal force. Which can be counterbalanced by a small (radioactive) rocket or something on every meter.
Almost any other relativistic device from literature would easily break long before this one.
If breaking was a problem.
1
Can you see why the rope in my example would break or stretch, even if we're moving it very very slowly?
-2
Your example isn't relevant for this discussion.
1
Why not?
-2
Look!
Not every relativistic projectile will be broken. And every projectile is relativistic, more or less.
Trying to escape from the Ehrenfest's paradox with saying - this starship breaks anyway - has a long tradition. Max Born invented that "exit".
Even if one advocates the breaking down of any torus which is moving/rotating relative to a stationary observer, he must explain why it breaks. And to explain the asymmetry created with this breakdown. Which internal/external forces caused it?
Resolving MM paradox with the Relativity created another trouble. Back to the drawing board!
Pretending that all is well is a regrettable attitude.
1
Why wouldn't that also apply to my rope example?
0
We, at this problem, don't care for a "comoving" inertial observer. We care for the stationary observer in the center, who first see stationary and then rotating torus, which should contract. But only in the direction of moving.
0
It's not the centrifugal force that's the problem. It's the force you are using to get the ring to start rotating.
0
Both forces are of the same magnitude! That's why we are waiting 10000000 years to get to a substantial speed.
If one is so afraid that forces even of that magnitude will somehow destroy the thing, one must dismiss all other experiments as well.
Ehrenfest was right, back in 1908. AFAIK he remained unconvinced by Einstein and others. It's a real paradox. Maybe I like it that much, because I came to the same conclusion long ago, without even knowing for Ehrenfest.
The question of the OP was about contrarian views. I gave 10 (even though I have about 100 of them). The 10th was about Relativity and I don't really expect someone would convert here. But it's possible.
1
Yes, and over 10000000 the forces can build up. Consider army's example of the stretching rope. Suppose I applied force to one end of a rope sufficient that over the course of 10000000 years it would double in length. You agree that the rope will either break or the bonds in the rope will prevent the rope from stretching?
The same thing happens with the rotation. As you rotate the object faster the bonds between the atoms are stretched by space dilation. This produces a restoring force which opposes the rotation. Either forces accelerating the rotation are sufficient to overcome this, which causes the bonds to break, or they aren't in which case the object's rotation speed will stop increasing.
0
(or stretch)
In the case of the ring there's another possibility.
-2
Irrelevant. How many tiny forces are inside a street car? They don't just "build up".
Nonsense.
2
No one's saying that forces "just build up" by virtue of applying for a long time. Azathoth123 is saying that in this particular case, when these particular forces act for a long time they produce a gradually accumulating change (the rotation of the ring) and that as that change increases, so do its consequences.
0
I understand. But imagine, that only 1 m of rope is accelerated this way. No "forces buildup" will happen.
As will not happen if we have rope around the galaxy.
1
Your rope is moving faster and faster, whether or not it goes all the way around the galaxy. The relations between different bits of the rope are pretty much exactly the setup for Bell's spaceship paradox.
-2
And? The Relativity isn't coherent, that's the whole point.
Transition from one, to another paradox doesn't save the day.
1
Yeah, but it's a "paradox" only in the sense of being confusing and counterintuitive, not in the sense of having any actual inconsistency in it. The point is that this is a situation that's already been analysed, and your analysis of it is wrong.
0
It wouldn't be a problem, if it was just "paradox", but unfortunately it's real.
We can't and therefore don't measure the postulated Lorentz contraction. We have measured the relativistic time and mass dilatation or increase, we did. But there is NO experiment confirming the contraction of length.
3
To get direct verification of length contraction we'd need to take something big enough to measure and accelerate it to a substantial fraction of the speed of light. Taking the fact that we don't have such direct verification as a problem with relativity is exactly like the creationist ploy of claiming that failure to (say) repeat the transition from water-dwelling to land-dwelling life in a lab is a problem with evolutionary biology.
-2
We have. The packet of protons inside LHC, Geneva.
Packets all around the circular tube. Nobody says, they shrink. They say those packets don't qualify for the contraction as they are "not rigid in Born's sens" and therefore not shrinking.
If we can measure even a tinny mass gain, we could measure a tinny contraction.
Had there been any.
1
Funny you should mention that.
0
See? It's only calculation based on Relativity, not actual experimental data.
1
If you read the whole article instead of quote-mining it for damning-looking sentences, you will see that that's incorrect.
They modelled, performed experiments, and compared the results. That's how science works. The fact that the article also mentions what happens in the models beyond the experimentally-accessible regime doesn't change that.
0
A bunch of particles not bound to each other by anything is not rigid in any reasonable sense I can think of, so what's your point?
0
Every rigid body is just a cloud of particles. If they are bonded together, they are bonded together with other particles like photons. Or gravity. Or strong nuclear force, as quarks in protons and neutrons.
Also the strong nuclear force is responsible for bounding atomic nucleus together. The force just doesn't stop at the "edge of a proton".
But why do you think they "must be bonded together" in the first place?

The link you gave does not talk about the direct observation of the Lorentz contraction. Rather of "explanations".
Fast traveling galaxies, of which all the sky is full, DO NOT show any contraction. That would qualify as a direct observation.

Hubble flow is at best a very noncentral example of travelling. Also, images aren't supposed to show any contraction (see Terrell rotation), only the objects themselves.

If images aren't supposed to show any contraction, then measurements aren't supposed to detect any contraction.

Are you saying, that there in an invisible contraction?

(Why are you expecting apparent sizes to match real sizes in the first place? The Sun looks as small as the Moon as seen from Earth, do you think it actually is?)
Of all light rays entering your eye right now, the ones coming from parts of the object farther away from you departed earlier than the ones coming from parts closer to you. If the object moved between those two times, its image will be deformed in a way that, when combined with Lorentz contraction, foreshortening, etc., will make the object look the same size as if it was stationary but rotated. This is known as Terrell rotation and there are animated illustrations of it on the Web.
(BTW, galaxies are moving along the line of sight, so their Lorentz contraction would be along the line of sight too, and how would you expect to tell (say) a sphere from an oblate spheroid seen flat face-first?)
I agree that “Lorentz contraction” is a misleading name; it's just a geometrical effect akin to the fact that a slab is thicker if you transverse it at an angle than if you transverse it perpendicularly.

Yes. Rotated rope looks shorter. Problem remains.
We see the close and the far edge of many of them. Still, the pancake apparently isn't neither squeezed neither rotated.

What problem?
1[anonymous]
There's a reason it's called special relativity. It only works in special cases. Eucludian geometry and Newtonian mechanics are inconsistent, btw. Special relativity solves these inconsistencies in the special contexts where they originally came up (predicting the Lorentz contraction and time dilation which is experimentally observed). It wasn't until the curved space of general relativity was discovered that we had a fully consistent model.
And yes, curved space of general relativity fully explains the rotating disc in a way that is self-consistent in in agreement with observed results (as proven by Gravity Probe B, among other things).
5
Special relativity is consistent. It just isn't completely accurate.
It's inconsistent with solid-body physics, but that's due to the oversimplifications inherent in solid-body physics, not the ones inherent in special relativity.
Trying to fit solid-body physics into general relativity is even worse. With special relativity, it works fine as long as it doesn't rotate or accelerate. Under general relativity, it can only exist on flat space-time, which basically means that nothing in the universe can have any mass whatsoever, including the object in question.

You need GR if you want to treat talk about the rotating reference frame of the disk. Otherwise SR is fine.
2
“claim[ing] that special relativity can't handle acceleration at all ... is like saying that Cartesian coordinates can't handle circles”
See http://math.ucr.edu/home/baez/physics/Relativity/SR/acceleration.html
But then again, the question whether the study of flat spacetime using non-inertial reference frames counts as SR depends on what you mean by SR. If you mean the limit of GR as G approaches 0, then it totally does.

You don't need GR for a rotating disk; you only need GR when there is gravity.

Rotation drags spacetime.

Only if the rotating object is sufficiently massive.
0[anonymous]
Only if the rotating object has any mass at all.
3
For a rotating object of sufficiently small mass, the mass can be ignored, and reasonably accurate results can be found with special relativity.
0[anonymous]
I don't disagree. This discussion was philosophical in the pejorative sense, being about absolutely exact results, not reasonable approximations.
2
The OP was claiming that special relativity was incoherent, not just that it wasn't absolutely exact.
If you want absolutely exact results, you'll need a theory of everything. There are quantum effects messing with spacetime.
0[anonymous]
Right. Well I'd agree that special relativity is incoherent for accelerating rotating frames -- it gives different experimental predictions depending on your choice of reference frame. It may be unusual to use accelerating reference frames, but they work just fine in classical physics. But they don't in special relativity.
It's not a very meaningful or contrarian statement though. Special relativity was known to be incoherent with regard to accelerating reference frames from day one. "Special" as in "special case", which it is. I guess my objection here is thta the OP listed it as a contrarian viewpoint, but as far as I can tell it is the standard view taught in Physics 103.
3
No they don't. From an accelerating reference frame, an object with no force on it will accelerate. You can only get it to work if you add a fictitious force.
I don't think it's accurate to call it incoherent for accelerating reference frames. If you try to alter the coordinate system so that something that was accelerating is at rest, and you try to predict what happens with the normal laws of physics, you'll get the wrong answer. But it never says you should get the right answer. There's symmetries in the laws of physics that cause them to be preserved by Lorentz transformations. Since a transformation can be found to make an arbitrary object be at rest at the origin and in a given orientation, it's often useful to use the transformation so that you can do the math with the object being at rest. Special relativity simply does not have such a symmetry to allow an accelerating object to be changed to an object at rest.
The fact that you can't use arbitrary "reference frames" doesn't mean that special relativity only works for a special case any more than using the (x,t) |-> (-t,x) transformation on Newtonian physics not working means that Newtonian physics only works in special cases and is incoherent.
The reason special relativity is a special case is that it only applies to flat spacetime, when no mass is involved.
1
What do you mean by this? Do you just mean that it doesn't make any sense for something infinite to actually exist, or do you mean that set theory, which claims the existence of an infinite set as an axiom, is inconsistent?
Why? It seems to me that it would be obvious if the standard theory that Venus gets most of its heat from the sun was wrong, since we can easily see how much it absorbs and emits and look at the difference. Besides which, you'd need expertise to have a reasonable chance of coming up with the correct explanation on your own. Do you have relevant expertise?

That's really more a personal taste than a view. The SF Bay Area is not inherently a good or bad place to live. Since you're the only person qualified to judge if you like living their, your opinion on the matter can hardly be considered contrarian. Not unless the majority of the people on LessWrong think you're wrong about not liking living there.

That is not in the rules for the thread. Given the karma toll (and the fact that sufficiently downvoted comment threads get collapsed), it would be a bad idea to make it one of the rules. I think you should simply not vote on comments you agree with, and I suggest reversing any downvotes you've made for this reason.
I do agree that without downvoting it is hard to differentiate between views the community agrees with and views the community has no real opinion about, but I don't think adding this information is worth the disadvantages of downvoting for agreement.

I think LW is already too biased towards contrarian ideas - we don't need to encourage them more with threads like this.
I think this thread is for opinions that are contrarian relative to LW, and not to the mainstream.
e.g. my opinion on open borders is something that a great majority of people share but is contrarian here, shown by the fact that as of the time of writing it is currently tied for highest-voted in the thread.

I think it's still a problem relative to LW.
Developing a rationalist identity is harmfull. Promoting a "-ism" or group affilication with the label "rational" is harmful.
2
Making your mind work better should not be a special action but a constant virtue. Categorising people into class A people that reach this high on sanity waterline and class B people that reach that high isn't healthy. Being rational isn't about being behind a particular answer to some central question. Being rational shouldn't be about social moment and it's inertia but about arguments and dissolving troubles.
The word choice itself is misleading as the word has very differnt meaning in mainstream use. It enforces and communicates an aura of superiority that hinders intercton with other same level disciplines. If being rational is about "prosperity by choice" or "prosperity by cognition" there exist other branches of "winning" that should not be positioned as enemies but rather accomplishes. There is atleast "prosperity by trust" and "prosperity by accumulation".

American intellectual discourse, including within the LW community, is informed to a significant extent by folk beliefs existing in the culture at large. One of these folk beliefs is an emphasis on individualism -- both methodological and prescriptive. This is harmful: methodological individualism ignores the existence of shared cultures and coordination mechanisms that can be meaningfully abstracted across groups of individuals, and prescriptive individualism deprives those who take it seriously of community, identity, and ritual, all of which are basic human needs.

I would not want to be cryonically frozen and resurrected as my sense of who I am is tied into social factors that would be lost

Would you be willing to freeze if your family did? Your friends and family? Your whole country? Or even if everyone in the world was preserved, would you expect the structure of society post-resurrection be different enough that you would refuse preservation?
3
I'm not usre about the friends and family examples, it would depend what I thought that future society would be like. If cryonics was the norm I probably wouldn't opt out of it because I would have reasonable expectation of, if resurrection was successful, there being other people in the same situation so there would be infrastructure to support us.
The social factors I'm thinking of include the skills, qualifications and experience that I have developed in my life, which would likely be irrelevant in a world that can resurrect me. At best I would be a historical curiosity with nothing to contribute.

That's fine. In some recent threads I've taken what I felt was a mainstream if leftist position, written (IMO) reasonable, positive arguments - and been downvoted for it, to the extent that I'm entertaining the hypothesis that LW is full of libertarians who are strongly opposed to such views. Confirming that out one way or the other is useful information.

I also have the general impression that in the past few months there has been an uptick of uncharitable tinman-attacks on progressivism by libertarians in the LW comment threads. Curiously, there seems to be less overt hostility between reactionaries and progressives, even though they're much further apart than libertarians and progressives (although this might be because the more hostile Nrx were more likely to exit after the creation of Moreright).

I take the downvotes Imm is getting for (informative, clear, concise) answers to requests for clarification -- and the number of downvotes his original perhaps-contrarian statement is getting (a larger fraction than any of the others I checked) -- as evidence that, in accordance with Imm's hypothesis, there are people on LW who regard holding left-wing views as an offence that requires punishment.

Computational Social Science (which is extremely methodology-oriented). I was trained in Political Science, but the lines between the social sciences are pretty fuzzy. I do substantive work which could be called Political Science, Sociology, or Economics.

I doubt you can find a widely-acceptable definition of Data Science which is any less fuzzy. Computational Social Science (CSS) is a subset of Data Science. Take Drew Conway's Data Science Venn Diagram: If your Substantive Expertise is a Social Science, you're doing Computational Social Science.

Perhaps you were exposed to better education. In Latin American universities, the humanities are plagued with antipositivism. If you've managed to stay away from it, kudos to you.

Oof. You just trampled one of my pet peeves: Social Science is a subset of the Sciences, not the Humanities.
There's still a persistent anti-positivist streak in the Humanities in the US, but mostly positivism has just been irrelevant to the work of Humanities scholars (though this is changing in some interesting and exciting ways).
More importantly, the social sciences in the US are overwhelming positivist, even amongst researchers whose work is not strictly empirical. I wish I could take credit for those good influences, but I think you're probably the one deserving of kudos for managing to become a rationalist in such a hostile environment.

When I said humanities I didn't mean social sciences; in fact, I thought social sciences explicitly followed the scientific method. Maybe the word points to something different in your head, or you slipped up. Either way, when I say humanities, I actually mean fields like philosophy and literature and sociology which go around talking about things by taking the human mind as a primitive.
The whole point of the humanities is that it's a way of doing things that isn't the scientific method. The disgraceful thing is the refusal to interface properly with scientists and scientific things - but there's no shortage of scientists who refuse to interface with humanities either, when you come down to it. My head's canonical example is Indian geneticists who try to go around finding genetic caste differences; Romila Thapar once gave an entertaining rant about how anything they found they'd be reading noise as signal because the history of caste was nothing like these people imagined.
And, on the other hand, we have many Rortys and Bostroms and Thapars in the humanities who do interface.
3
Funny humanities people were saying the same thing about genetic racial differences until said difference started showing up.
0
a) Actually Thapar's point wasn't that there were no genetic differences (in fact, the theory of caste promulgated by Dalit activists is that it's created by the prohibition of inter-caste marriage and therefore pretty much predicts genetic differences) - but that the groupings done by the researchers wasn't the correct one.
b) I should actually check that what I surmised is what she said. Thanks for alerting me to the possibility.
0
So do you have independent evidence that the theory promulgated by the Dalit activists is correct, because theories promulgated by activists don't exactly have the best track record.
0
Actually, with the caveat that I don't have any object-level research, I doubt it; they assign a rigidity to the whole thing that seems hard to institute. My point was that 'do there exist genetic differences' is not the issue here.
0
So what is the issue, that geneticists didn't consult with Dalit activists before designing their experiment?
2
So, Romila Thapar is not a Dalit activist, just a historian (I'm guessing this is a source of confusion; I could be wrong).
I'm saying they should have read up before starting their project.
I can't find the study for some reason, so I'll try and do it from memory. They randomly picked from a city Dalits (Dalit is a catch-all term coined by B R Ambedkar for people of the lowest castes, and people outside the caste system, all of whom were treated horribly) and people from the merchant castes to look for genetic differences. Which is all fine and dandy - but for the fact that neither 'Dalit' not 'merchant-caste' is an actual caste; there are many castes which come into those two categories. So, assuming a simple no-inter-caste-marriage model of caste, a merchant family from village A thousands of kilometres from village B has about as much (or, considering marginal things like babies born out of rape, even less) genetic material in common than a merchant and Dalit family from the same village - unless there's a common genetic ancestor to all merchant families. And that's where reading historical literature comes in - the history of caste is much more complicated, involving for example periods when it was barely enforced and shuffling and all sorts of stuff. So, they will find differences in their study, but it won't reflect actual caste differences.
2
The problem is that they're trying to study areas where it's really hard to get enough scientific evidence.

There is nothing morally wrong about eating meat, and vegetarianism/veganism aren't morally superior to meat-eating.

At the time of the poll people had requested more granularity in the answers. I think a lot of folks leaned towards veggie ideas in the sense of reduced or substanceualy below average meat consumption without actualy being vegitayians.
As to how many a lot was, who knows. I think it's likely that vegetarianism is probably more acceptable here than in the population at large and so disagreeing with it would be more contrarian

For most of the vegetarians I know, the issue isn't inherently eating meat. It's the way the animals are treated before they are killed.

Maybe you know a weird subset of vegetarians, but I don't think most would be fine with eating a dead animal that has been very well treated throughout its life.

If its price was less than or equal to the price of normal meat, I'd buy it, otherwise, I'd stick with normal meat.

I suspect it will end up being cheaper because it would be faster to produce than an entire life-cycle of an animal...
This seems pretty similar to the irrationality game. That's not necessarily a bad thing, but personally I would try the following formula next time (perhaps this should be a regular thread?):
Ask people to defend their contrarian views rather than just flatly stating them. The idea here is to improve the accuracy of our collective beliefs, not just practice nonconformism (although that may also be valuable). Just hearing someone's position flatly stated doesn't usually improve the accuracy of my beliefs.
Ask people to avoid upvoting views they already agree with. This is to prevent the thread from becoming an echo chamber of edgy "contrarian" views that are in fact pretty widespread already.
Ask people to vote up only those comments that cause them to update or change their mind on some topic. Increased belief accuracy is what we want; let's reward that.
Ask people to downvote spam and trolling only. Through this restriction on the use of downvotes, we lessen the anticipated social punishment for sharing an unpopular view that turns out to be incorrect (which is important counterfactually).
Encourage people to make contrarian factual statements rather than cont

This has the problem that beliefs with a large inferential distance won't get stated.
The rest of your points seem to boil down to the old irrationality game rule of downvote if you agree, upvote if you disagree.
3
Is it useful to have beliefs with a large inferential distance stated without supporting evidence? Given that the inferential distance is large, I'm not going to be able to figure it out on my own am I? At least having a sketch of an argument would be useful. The more you fill in the argument, the more minds you change and the more upvotes you get.
"Upvote if the comment caused you to change your mind" is not the same thing as "upvote if you disagree".
Another idea, which kinda seems to be getting adopted in this thread already: have a short note at the bottom of every comment right above the vote buttons reminding people of the voting behavior for the thread, to counteract instinctive voting.

Is there some way to encourage coherence in people's stated views? For some of the posts in this thread I can't tell whether I agree or disagree because I can't understand what the view is. I feel an urge to downvote such posts, although this could easily be a bad idea, since extreme contrarian views will probably seem less coherent. On the other hand, if I can't even understand what is being claimed in the first place then it's hard for me to get much benefit out of it.
5
That's to be expected with it comes to contrarian views. A lot of positions are not widely held because they are complicated to understand or take certain background knowledge.
If you would give me a bunch of academic math problems I wouldn't understand the problems. In math it's fairly easy to say: Hey math is complicated, it's okay that I don't know enough about the topic to understand the claim. But in other areas the same applies. Understanding what other people think is often hard when they differ substantially from yourself.

The outside view on this is that such predictions have been made since the start of A(G)I 50 or 60 years ago, and it's never panned out. What are the inside-view reasons to believe that this time it will? I've only looked through the table of contents of the Goertzel book -- is it more than a detailed survey of AGI work to date and speculations about the future, or are he and his co-workers really onto something?
4[anonymous]
My prediction / contrarian belief is that they are really onto something, with caveats (did you look at the second book? that's where their own design is outlined).
At the very highest level I think their CogPrime design is correct in the sense that it implements a human-level or better AGI that can solve many useful categories of real world problems, and learn / self-modify to solve those categories it is not well adapted to out of the box.
I do take issue with some of the specific choices they made in both fleshing out components and the current implementation, OpenCog. For example I think using the rule-based PLN logic engine was a critical mistake, but at an architectural level that is a simple change to make since the logic engine is / should be loosly coupled to the rest of the design (it's not in OpenCog, but c'est la vie. I think a rewrite is necessary anyway for other reasons). I'd swap it out for a form of logical inference based on Bayesian probabalistic graph models a la Pearl. There are various other tweaks I would make regarding the atom space, sub-program representation, and embodiment. I'd also implement the components within the VM language of the AI itself, such that it is able to self-modify its own core capabilities. But at the architectural level these are tweaks of implementation details. It's remains largly the same design outlined by Goertzel et al.
AI has been around for almost 60 years. However AGI as a discipline was invented by Goertzel et al only in the last 10 to 15 years or so. The story before that is honestly quite a bit more complex, with much of the first 50 years of AI being spent working on the sub-component projects of an integrative AGI. So without prototype solutions to the component problems, I don't find it at all surprising that progress was not made on integrating the whole.

You can expect to have about as much success effectively and systematically teaching rationality as you could in effectively and systematically teaching wisdom. Attempts for a systematic rationality curriculum will end up as cargo cultism and hollow ingroup signaling at worst and heuristics and biases research literature scholarship at best. Once you know someone's SAT score, knowing whether they participated in rationality training will give very little additional predictive power on whether they will win at life.

I'd like to hear a more substantive argument if you've got one. Do you think there are few general-purpose life skills (e.g. those purportedly taught in Getting Things Done, How to Win Friends and Influence People, etc.)? What's your best evidence for this?
1
I think that there is a huge unseen component in life skills where in addition to knowing about a skill, you need to recognize a situation where the skill might apply, remember about the skill, figure out if the skill is really appropriate given what's going on, know exactly how you should apply the skill in that given situation and so on. There isn't really an algorithm you can follow without also constantly reflecting on what is actually going on, and I think that in what basically looks like another instance of Moravec's paradox, the big difficult part is actually in the unconscious situation awareness and the things you can write in a book like GTD and give to people are a tiny offshoot on that.
No solid evidence for this except for the observation that there don't seem to be self-helpy systems for general awesomeness that actually do consistently make people who stick with them more awesome.

OK, what if you were to, say, at the end of each day brainstorm situations during the day when skill X could have been useful in order to get better at recognizing them?
Could meditation be useful for this?

Sounds like this would still run into the problem I anticipate and be hindered by poor innate memory and pattern matching abilities or low conscientiousness. Some people just won't recognize the situation even in retrospect or have already forgotten about it.
Here's an example of what a less than ideal teaching scenario might look like. If MIT graduates are one end of the spectrum, that's close to the another, and most people are going to be somewhere in between.
Meditation is definitely one of the more interesting self-improvement techniques where you basically just follow an algorithm. Still, it probably won't increase your innate g, much like nothing else seems to. And there are some not entirely healthy subcultures around extensive meditation practices (detachment from the physical world as in "the only difference between an ideal monk and a corpse is that the monk still has a beating heart" and so on), which might be trouble for someone who really wants an algorithm to follow and grabs on to meditation without having much of a counterweight in their worldview.

EDIT: I also don't think that your description would go very far, it'd still end up with the innately clever people dominating, and the rest just stuck in the general arms race and the confusion of actually effectively applying the skills to the real world, just like all the self-help we already have that teaches that stuff seems to end up.

Engaging in political processes (and learning how to do so) is a useful thing, and is consistently underrated by the LW consensus.

Just a reminder, the local meme "politics is the mind killer" is an injunction not against discussing politics, but against using political examples in a non-political argument.

Agreed. But there is also a generally negative attitude towards politics
Dollars and utilons are not meaningfully comparable.
Edited to restate: Dollars (or any physical, countable object) cannot stand in for utilons.
3
Can you explain what is wrong with the following comparison?
The value of a dollar in utilons is equal to the increase in expected utilons brought by being given another dollar.
3
The problem is the law of diminishing marginal utility. Translating from dollars to utilons is not straightforward at all; how much utility that dollar gives you depends on factors like how many dollars you already have, how much you owe, what services you can sell, and how much you know about what to do with money. For that same reason, utilons do not add up linearly by giving you a second, third, etc., dollar.
5
Right; assuming (falsely of course) that humans have coherent preferences satisfying the VNM axioms, what can be measured in utilons are not "amount of dollars" in the abstract, but "amount of dollars obtained in such-and-such way in such-and-such situation". But I wouldn't call this "not being meaningfully comparable". And there is nothing special about dollars here, any other object, event or experience is subject to the same.
1
Every time there's an argument that goes like, "Would you pay a penny to avoid scenario X?", which in real life means actually "Would you sacrifice a utilon to avoid scenario X?" and therefore requires us to presuppose that dollars can stand in for utilons, something special is being assumed about dollars.
2
But "Would you pay a penny to avoid scenario X?" in no way means "Would you sacrifice a utilon to avoid scenario X?" (the latter is meaningless, since utilons are abstractions subject to arbitrary rescaling). The meaningful rephrasing of the penny question in terms of utilons is "Ceteris paribus, would you get more utilons if X happens, or if you lose a penny and X doesn't happen?" (which is just roundabout way of asking which you prefer). And this is unobjectionable as a way of testing whether you have really a preference and getting a vague handle on how strong it is.
I would prefer if people avoided the word "utilon" altogether (and also "utility" outside of formal decision theory contexts) because there is an inevitable tendency to reify these terms and start using them in meaningless ways. But again, nothing special about money here.
1
Seconded. But then we would also need to avoid using language that sneaks disguised utilons into the conversation.
0
If you had another dollar, then the value of the next dollar in utilons would decrease. Unless you're both an egoist and terrible with money, it will only be a slight decrease. After all, a dollar isn't much compared to all of the money you will make over your life.
I do not think that the fact that utilons do not add up linearly means that the conversion is not useful. For one thing, it allows you to express the law of diminishing marginal utility.
2
Utilons do not exist. They are abstractions defined out of idealized, coherent preferences. To the extent that they are meaningful, though, their whole point is that anything one might have a preference over can be quantified in utilons--including dollars.
My current understanding of U.S. laws on cryonics is that you have to be legally pronounced brain-dead before you can be frozen. I think that defeats the entire purpose of cryonics; I can't trust attempts to reverse-engineer my brain if I'm already brain-dead; that is, if my brain cells are already damaged beyond resuscitation. I don't live in the U.S. anyway, but sometimes I consider moving there just to be close to cryonics facilities. However, as long as I can't freeze my intact brain, I can't trust the procedure.
8
brain dead does not necessarily refer to damaged brain cells. It often refers to electrical activity. As people have been resuscitated after the cessation of brain activity (i.e. human's are cold bootable) without loss of personality it seems reasonable to still give cryonics a go.

Somewhere between 1950 and 1970 too many people started studying physics, and now the community of physicists has entered a self-sustaining state where writing about other people's work is valued much, much more than forming ideas. Many modern theories (string theory, AdS/CFT correspondence, renormalisation of QFT) are hard to explain because they do not consist of an idea backed by a mathematical framework but solely of this mathematical framework.

Friendliness by mathematical proof about exact trustworthiness of future computing principles is misguided.
I sense this opinion is not that marginal here, but it does go against the established orthodoxy: I'm pro-specks.

Meaning, in this scenario, I prefer 3^^^3 specks to 50 years of torture for one person.

I think that my objection is that the analysis sneaks in an ontological assumption: sensory experiences are comparable across a huge range. I'm not very sure that's true.
1
What does it mean for something to be incomparable? You can't just not decide.
2
Sensory experiences that reliably change utility functions are hard to reason about.
1
I'm not sure what you mean. Are you saying that since torture will destroy someone's mind, it's vastly worse than a dust speck, and exactly how much worse is nigh impossible to tell?
It can't be that hard to tell. Maybe you're not sure whether or not it's in the range of ten thousand dust specks to a quintillion dust specks, but it seems absurd to be so confused about it that you don't even know if it's worse than 3^^^3 dust specks.
2
What's your reasoning? I expect serious attempts at an answer to have to cope with questions such as —
* How many degrees of pain might a human be capable of? Is the scale linear? logarithmic?
* How does the 'badness' (or 'natural evil', classically) of pain vary with its intensity and its duration? (Is having a nasty headache for seven days exactly seven times worse than having that headache for one day, or is it more or less than seven times worse?)
* How does the 'badness' of some pain happening to N people scale with N? (If 100 people stub their toes, is that 100 times worse than one person stubbing his or her toe and 99 going safely unstubbed?)
Even if questions such as these can't be given precise answers, it should be possible to give some sort of bounds for them, and it's possible that those bounds are narrow enough to make the answer obvious.
5
You want a scientific scale for measuring pain? Take your pick.
Not only is there no universally standardized measure of pain, the reason why I'm pro-specks is that I don't believe that pain distributed over separate brains is summable. It does not scale.
Elsewhere EY argued that a billion skydivers, each increasing the atmosphere's temperature by a thousandth of a degree, would individually not care about the effect, but collectively kill us all. The reason why the analogy doesn't apply is that all the skydivers are in the same atmosphere, whereas the specks are not hurting the same consciousness. Unless the pain is communicable (via hive mind or what have you), it will still be roundable to zero. You could have as many specks as you like, each of them causing the mildest itch in one eye, and it would still not surpass the negative utility from torturing one person.
Edited to add: I still don't have a clear idea of how infinite specks would change the comparison, but infinites don't tend to occur in real life.
1
If the problem was solvable that easily, it wouldn't be a problem.
Just slightly change the definition of "speck" (or reinterpret the intent of the original definition): let a speck be "an amount of pain just slightly above the threshold where the pain no longer rounds down to zero for an individual". Now would you prefer specks for a huge number of people to torture for one person?
3
I'm already taking "speck" to have that meaning. Even raising the threshold (say, 3^^^3 people stubbing their toe against the sidewalk with no further consequences), my preference stands.
4
If you're already taking "speck" to have that meaning, then your statement "Unless the pain is communicable (via hive mind or what have you), it will still be roundable to zero." would no longer be true.
4
Granted. Let's take an example of pain that would be decidedly not roundable to zero. Say, 3^^^3 paper cuts, with no further consequences. Still preferable to torture.
6
(What I'm about to say is I think the same as Jiro has been saying, but I have the impression that you aren't quite responding to what I think Jiro has been saying. So either you're misunderstanding Jiro, in which case another version of the argument might help, or I'm misunderstanding Jiro, in which case I'd be interested in your response to my comments as well as his/hers :-).)
It seems to me pretty obvious that one can construct a scale that goes something like this:
* a stubbed toe
* a paper cut
* a painfully grazed knee
* ...
* a broken ankle
* a broken leg
* a multiply-fractured leg
* ...
* an hour of expertly applied torture
* 80 minutes of expertly applied torture
* ...
* a year of expertly applied torture
* 13 months of expertly applied torture
* ...
* 49 years of expertly applied torture
* 50 years of expertly applied torture
with, say, at most a million steps on the scale from the stubbed toe to 50 years' torture, and with the property that any reasonable person would prefer N people suffering problem n+1 to (let's say) (1000N)^2 people suffering problem n. So, e.g. if I have to choose between a million people getting 13 months' torture and a million million million people getting 12 months' torture, I pick the former.
(Why not just say "would prefer 1 person suffering problem n+1 to 1000000 people suffering problem n"? Because you might take the view that large aggregates of people matter sublinearly, so that 10^12 stubbed toes aren't as much worse than 10^6 stubbed toes as 10^6 stubbed toes are than 1. The particular choice of scaling in the previous paragraph is rather arbitrary.)
If so, then we can construct a chain: 1 person getting 50 years' torture is less bad than 10^6 people getting 49 years, which is less bad than 10^18 people getting 48 years, which is less bad than [... a million steps here ...] which is less bad than [some gigantic number] getting stubbed toes. That final gigantic number is a lot less than 3^^^3; if you r
1
(Small nitpicking: The pain from "a multiply-fractured leg" may bother you longer than "an hour of expertly applied torture", but the general idea behind the scale is clear.)
In this case I'd choose as you do, just as in Jiro's example:
The problem with these scenarios, however, is that they introduce a new factor: they're comparing magnitudes of pain that are too close to each other. This not only applies to the amount of pain, but also to the amount of people:
I'd rather be tortured for 12 than 13 months if those were my only options, but after having had both experiences I would barely be able to tell the difference. If you want to pose this problem to someone with enough presence of mind to tell the difference, you're no longer torturing humans.
(If psychological damage is cumulative, one month may or may not make the difference between PTSD and total lunacy. Of course, if at the end of the 12 months I'm informed that I still have one more month to go, then I will definitely care about the difference. But let's assume a normal, continuous torture scenario, where I wouldn't be able to keep track of time.)
This is why,
runs into a Sorites problem that is more complex than EY's blunt solution of nipping it at the bud.
In another thread (can't locate it now), someone argued that moral considerations about the use of handguns were transparently applicable to the moral debate on nuclear weapons, and I didn't know how to present the (to me) super-obvious case that nuclear weapons are on another moral plane entirely.
You could say my objection to your 50 Shades of Pain has to do with continuity and with the meaningfulness of a scale over very large numbers. Such a quantitative scale would necessarily include several qualitative transitions, and the absurd results of ignoring them are what happens when you try to translate a subjective, essentially incommunicable experience into a neat progression of numbers.
(You could remove that obstacle by asking self-aware
2
That was in response to your idea that small amounts of pain cannot be added up, but large amounts can.
If this is true, then there is a transition point where you go from "cannot be added up" to "can be added up". Around that transition point, there are two pains that are close to each other yet differ in that only one of them can be added up. This leads to the absurd conclusion that you prefer lots of people with one pain to 1 person with the other, even though they are close to each other.
Saying "the trouble with this is that it compares magnitudes that are too close to each other" doesn't resolve this problem, it helps create this problem. The problem depends on the fact that the two pains don't differ in magnitude very much. Saying that these should be treated as not differing at all just accentuates that part, it doesn't prevent there from being a problem.
0
I'm thinking of the type of scale where any two adjacent points are barely distinguishable but you see qualitative changes along the way; something like this.
1
That doesn't solve the problem. The transition from "cannot be added up" to "can be added up" happens at two adjacent points.
0
As I don't think pain can be expressed in numbers, I don't think it can be added up, no matter its magnitude.
1
In that case, you can't even prefer one person with pain to 3^^^^3 people with the same pain.
(And if you say that you can't add up sizes of pains, but you can add up "whether there is a pain", the latter is all that is necessary for one of the problems to happen; exactly which problem happens depends on details such as whether you can do this for all sizes of pains or not.)
1
Doesn't that make the argument stronger? I mean, if you're not even sure that 13 months of torture are much worse than 12 months of torture, then you should be pretty confident that 10^6 instances of 12 months' torture are worse than 1 instance of 13 months' torture, no?
So that was the option I described as "abandon continuity". I was going to ask you to be more specific about where those qualitative transitions happen, but if I'm understanding you correctly I think your answer would be to say that the very question is misguided because there's something ineffable about the experience of pain that makes it inappropriate to try to be quantitative about it, or something along those lines. So I'll ask a different question: What do those qualitative transitions look like? What sort of difference is it that can occur between what look like two very, very closely spaced gradations of suffering, but that is so huge in its significance that it's better for a billion people to suffer the less severe evil than for one person to suffer the more severe?
(You mention one possible example in passing: the transition from "PTSD" to "total lunacy". But surely in practice this transition isn't instantaneous. There are degrees of psychological screwed-up-ness in between "PTSD" and "total lunacy", and there are degrees of probability of a given outcome, and what happens as you increase the amount of suffering is that the probabilities shift incrementally from each outcome to slightly worse ones; when the suffering is very slight and brief, the really bad outcomes are very unlikely; when it's very severe and extended, the really bad outcomes are very likely. So is there, e.g., a quantitative leap in badness when the probability of being badly enough messed-up to commit suicide goes from 1% to 1.01%, or something?)
If you mean that anyone here is assuming some kind of moral calculus where suffering is denominated in torture-years and is straightforwardly additive across people, I thi
4
Presumably, you still think that large amounts of pain can be added up.
In that case, that must have a threshold too; something that causes a certain amount of pain cannot be added up, while something that causes a very very slightly greater amount of pain can add up. That implies that you would prefer 3^^^3 people having pain at level 1 to one person having pain of level 1.00001, as long as 1 is not over the threshold for adding up but 1.00001 is. Are you willing to accept that conclusion?
(Incidentally, for a real world version, replace "torture" with "driving somewhere and accidentally running someone over with your car" and "specks" with "3^^^3 incidences of not being able to do something because you refuse to drive". Do you still prefer specks to torture?)
3
As I stated before, doctors can't agree on how to quantify pain, and I'm not going to attempt it either. This does not prevent us from comparing lesser and bigger pains, but there are no discrete "pain units" any more than there are utilons.
I would choose the certain risk of one traffic victim over 3^^^3 people unable to commute. But this example has a lot more ramifications than 3^^^3 specks. The lack of further consequences (and of aggregation capability) is what makes the specks preferable despite their magnitude. A more accurate comparison would be choosing between one traffic victim and 3^^^3 drivers annoyed by a paint scratch.
4
If you can compare bigger and smaller pains, and if bigger pains can add and smaller pains cannot, you run into this problem. Whether you call one pain 1 and another 1.00001 or whether you just say "pain" and "very slightly bigger pain" is irrelevant--the question only depends on being able to compare them, which you already said you can do. What you say implies that you would prefer 3^^^3 people with a certain pain to 1 person with a very slightly bigger pain. Is this really what you want?

I think most people who suffer from back pain suffer from back pain because their muscles do something they shouldn't do. RSI is probably also an illness that has to do with muscles engaging in patterns of activation that's aren't healthy.
I personally had to relearn walking after 7 weeks of being in bed in the hospital. You need an amazing number of different muscles to walk and if you don't use a bunch you are walking suboptimally.
These days you can use approaches such as Feldenkrais to relearn how to use all your muscles but Feldenkrais isn't really science-based. A real science of movement that would have equipment that measures human movement very exactly and then runs machine learning algorithms over those measurements is likely yield a science-based version of Feldenkrais that's more efficient and where you can diagnose issues much better to be able to say beforehand whether Feldenkrais will help a person.

I think I've found a scientifically-based system. It's based on anatomy, and uses pressure plates to establish how people move their weight when they stand and walk.
Unfortunately, the book costs $60, and is a book of principles and facts, not methods. Even though it's directed toward body-workers rather than people in general, it still doesn't include the exercises for activating the appropriate movement patterns to improve walking.
Nonetheless, I'm experimenting cautiously with what I can get out of it-- gently shifting the weight transfer patterns in my feet while walking toward what's recommended, for example. This may be doing some good, but I'll do more of a report later.

It might be a bit measurement based but that alone doesn't mean it's science-based. As far as I can see the author doesn't hold an academic degree and doesn't even think that it's important to have somebody with an academic degree recommend his method if you look at the testimonial page. I don't see references to published papers on the website.
Of course that doesn't mean that the knowledge in the book isn't useful. On the other hand it doesn't help with sanctioning treatment as evidence-based and getting them covered by mainstream medical providers.

What would science-based Feldenkreis teaching look like?
How would you get from "machine learning algorithms over measurements", which sounds like statistical curve-fitting, to actionable conclusions, about how people should use their bodies, and how to teach people how to do that? No-one can follow instructions like "increase activation of the iliopsoas by 3%", even if you somehow validated a causal model that made that a useful thing to do in some situation. People can barely follow verbal instructions at all about posture and movement.
2
The problem is that we don't really know which instructions people can easily follow and which they can't follow. If the problem is "increasing activation of the iliopsoas by 3%" you can empirically test various interventions. Without having a casual model of what kind of movement is good, you can't validate interventions and determine whether the intervention is good.
Apart from that it's possible to do biofeedback. Good feedback can give humans perception and control over many variables.
On the other hand you can make a similar argument about the useful of understanding how proteins do what they do. Just because you understanding a pathway doesn't mean you can manipulate it the way you want. Science advances by first mapping the space of phenomena and then hopefully finding a way to intervene.

I think video are the wrong medium. Videos have the problem of getting people to think they understand something when they don't. People learn all the right buzzwords but that doesn't mean that they actually are more rational.
Kaj Sotala for example designs a game for his master thesis that's intended to teach Bayes method. I think such a game would be much more valuable than a video that explains Bayes method.
We have prediction book and the Credence game as tools to teach people to be more rational. They aren't yet on a quality level where the average person will use them. Focusing more energy on updating those concepts and making them work better is more valuable than producing videos.
CFAR also does develop teaching materials. A core feature of CFAR is that it actually focuses on produces quality instead of just producing videos and hoping that those videos will have an impact. I know that there someone in Germany who teaches a high school class based on CFAR inspired material.

Seems pretty sensible to me. I'm not that worried about a 30-40 year old "rationalist" movement, however... in the same way the ideas on LW appealed to me as a teen, it seems likely that they will end up appealing to other teens, if they end up hearing about them (stuff like e.g. HPMOR makes it likely that they will).

On the other other other hand, some people who might be able to help with AI risk might get into the possibly-less-important sanity-waterline-raising projects, and this would be a bad thing.

CEV assumes that things can be made coherent. This ignores on how tendensies of pulling in opposite directions play out in practise. This might be a feature and not a bug. The extra polation part is like predicting growth without actual growing. It will lead to another place than natural growth would result with. It also assumes that humans will on the whole cooperate. How should the AI approach conflicts of interest against the constituents? If there is another cold war style scenario does it mean most of the AI power is wasted on being neutral? Or does the AI just empower indiviudal symmetry breakingt decisions to bgi scales, in that the AI isn't the one that f up everything it just supplies the one at fault with tools to make it big.

Our society is ruled by a Narrative which has no basis in reality and is essentially religious in character. Every component of the Narrative is at best unjustified by actual evidence, and at worst absurd on the face of it. Moreover, most leading public intellectuals never seriously question the Narrative because to do so is to be expelled from their positions of prestige. The only people who can really poke holes in the Narrative are people like Peter Thiel and Nassim Taleb, whose positions of wealth and prestige are independently guaranteed.

Finding better ways for structuring knowledge is more important than faster knowledge transfer through devices such as high throughput Brain Computer Interfaces.
It's a travesty that outside of computer programming languages few new languages get invented in the last two decades.

I understand; that's why they're related. But they're not the same statement; someone could agree with your first statement and disagree with your second. In fact, they could agree that finding better ways of structuring knowledge is really important, and agree that languages are ways of structuring information, but not think it's a bad thing that languages aren't being invented faster -- e.g., they might hold that outside of computer programming, there are almost always better ways to improve how we structure information than by inventing new languages.

I interpret the intention as "upvote serious ones you disagree with, downvote trolls, ignore those you agree with". In other words, you are not judging what you think LW finds contrarian, you are reporting whether you agree with the views posters perceive as contrarian, not penalizing people for misjudging what is contrarian.

Once you actually take human nature into account (especially, the the things that cause us to feel happiness, pride, regret, empathy), then most seemingly-irrational human behavior actually turns out to be quite rational.

From 1 and 2 it follows that most attempts at trying to consciously improve 'rational' behavior will end up falling short or backfiring.

I agree, which probable makes it contrarian.
History isn't over in any Fukuyamian sense; in fact the turmoil of the twenty-first century will dwarf the twentieth. A US-centered empire will likely take shape by century's end.

I agree with the first sentence, I disagree with the second. Few countries managed more than a century of world domination and the US is already showing the classic signs of decay.

I've always had problems with MWI, but it's just a gut feeling. I don't have the necessary specialized knowledge to be able to make a decent argument for or against it. I do concede it one advantage: it's a Copernican explanation, and so far Copernican explanations have a perfect record of having been right every time. Other than that, I find it irritating, most probably because it's the laziest plot device in science-fiction.
7
Technical explanation: the problem with MWI is that it makes the fact that density matrices work seem like a complete epistemological coincidence.
Incidentally, I remember a debate between Eliezer and Scott Aaronson where the former confessed he stopped reading his QM textbook right before the chapter on density matrices.
2
I don't understand what you mean. Could you explain? I'm familiar with QM, so you don't need to avoid technicality in your explanation.

Suppose we have two jars of qubits:
Half the qubits in jar (1) are in state |0> and the other half are in state |1>.
Half the qubits in jar (2) are in state |+> and the other half are in state |->.
Notice that although from a classical Bayesian MWI perspective the two jars are in very different states, there is no way to tell them apart even in principal.
2
BTW, that's the only reason why I'm not fully convinced by realist interpretations of QM.

What's a Copernican explanation?
4
I've never heard the term before, but in context I'd guess it means something like "an explanation that implies we're less important than the previous explanation did". Heliocentrism vs. geocentrism, evolution vs. a supernatural creation narrative culminating in people, etc.
1
Freud's psychoanalysis has been often put in the same category of "Copernican" things as heliocentrism and evolution.
1
Why is MWI more Copernican than the Copenhagen interpretation?
You do realize that an "observer" doesn't have to be conscious, right? The Copenhagen interpretation doesn't treat humans specially. If anything, I'd say that the Copenhagen interpretation is more Copernican, since it explains the Born probabilities without requiring anthropics.
1
My comment was not intended to be an endorsement of polymathwannabe's analysis. I'm not a QM expert and am not qualified to comment on the details of either interpretation.

The Copernican principle states that there's nothing special or unique or privileged about our local frame of reference: we're not at the center of the solar system, we're not at the center of the galaxy, this is not the only galaxy, and the next logical step would be to posit that this is not the only universe.

I do not believe in reincarnation of any sort. I believe this is my only life.
It has been believed that the Earth was flat. I'm sure at least someone had considered the implication that the Earth goes on forever. This has turned out to be false. The Earth has positive curvature, and thus only finite surface area.
Quite a few people have considered the idea that atoms are little solar systems, which could have their own life. It turns out that electrons are almost certainly fundamental particles. And even if they're not, the way physics works on a small scale is such that life would be impossible.
Similarly, galaxies do not make up molecules. Even if there are other forces as would be necessary, the light speed limit combined with the expansion of the universe creates a cosmological event horizon. Beyond a certain scale, it is physically impossible for anything to interact.
There are a variety of physical theories that predict other universes. They work in different ways, and tend not to be contradictory. It would be unwise to reject them out of hand, but it would be equally unwise to automatically accept them.

You can't solve AI friendliness in a vacuum. To build a friendly AI, you have to simultaneously work on the AI and the code of ethics it should use, because they are interdependent. Until you know how the AI models reality most effectively you can't know if your code of ethics uses atoms that make sense to the AI. You can try to always prioritize the ethics aspects and not make the AI any smarter until you have to do so, but you can't first make sure that you have an infallible code of ethics and only start building the AI afterwards.

How is this different from the LW mainstream?

Any work on AI implementation is seriously downvoted here.

The last time I saw someone suggest that one should build an AI without first solving friendliness completely, he was heavily downvoted. I found that excessive, which is why I posted this. I am positively surprised to see that I basically got no reaction with my statement. My memory must have been exaggerated with time, or maybe it was just a fluke.
edit: I now seriously doubt my previous statement. I just got downvoted on a thread in which I was explicitly instructed to post contrarian opinions and where the only things that should get downvotes are spam and trolling, which I didn't do. Of course it's also just possible that someone didnt read the OP and used normal voting rules.

Toxicology research is underfunded. Investing more money into finding tools to measure toxicology makes more sense than spending money into trying to understand the functioning of various genes.
4
I'm not sure whether I agree or disagree. What's your line of thought?
5
Scientific progress has a lot to do with having powerful tools. If you get more powerful tools you can easily get a bunch of new insight. As a result it's worthwhile to focus most of our efforts on building better tools instead of funding specific insights.
Secondly the standard way to judge whether something is poisonous is to see how big of a dose you need to kill rats. If the substance doesn't kill rats or reduce their lifespan but it just reduces their IQ our tox tests don't pick it up. That means that we might have pesticides in use that do things like reducing IQ at doses that are legally allowed without our testing procedure being able to tell.
Practically we could measure variables like the heart rate of a labrat via infrared for it's whole lifespan and see whether it shows unusual patterns. Every action that the rat does in their lifetime could be measured. The rat lives in a controlled environment where a lot of information besides whether or not the rat dies can be gathered.
Of course we already do some additional tests such as a test for whether a substance might cause cancer that has nothing to do with rats but in general we could do much better at measuring toxicology.
On the one hand that means that we could regulate harmful substances where we currently don't know they are harmful. On the other hand drug development also get's cheaper if you catch bad drugs while you do your tests with rats and before you run expensive trials with humans.

The many worlds interpretation of quantum mechanics is categorically confused nonsense. Its origins lie in a map/territory confusion, and in the mind projection fallacy. Configuration space is a map, not territory—it is an abstraction used for describing the way that things are laid out in physical space. The density matrix (or in the special case of pure states, the state vector, or the wave function) is a subjective calculational tool used for finding probabilities. It's something that exists in the mind. Any 'interpretation' of quantum mechanics which claims that any of these things exists in reality (e.g. MWI) therefore commits the mind projection fallacy.

Homeownership is not a good idea for most people.
0
Please elaborate.
0
The largest avoidable source of pain and boredom in the life of a typical western citizen is their commute. - The sane response to this problem is to live as close to your place of employment as at all practical - valuing the time spent commuting at the same rate as your hourly earnings, the monthly penalty for living any significant distance at all from your job can get quite absurd for professionals just in financial terms, and the human cost is greater, because it is sucking up the time you actually can dispose of as you wish.
Home ownership increases the costs of moving residence dramatically compared to renting, and is thus not a good idea unless you have a job which you anticipate keeping for a far greater period of time than is typical in modern society. IE, do you have tenure or the effective equivalent? Then buying over renting makes sense. If you don't, all buying does is make it hurt a lot more to move when you get a new job.

This looks like two posts I saw quite a while ago where contrarian posts were also intended to be up-voted. I can't seem to find those posts (searching for contrarian doesn't match anything and searching for 'vote' is obviously useless). Nonetheless those posts urged to mark each contrarian comment to clearly indicate the opposite voting semantics to avoid unsuspecting readers being misled by the votes. Maybe someone can provide the links?

Now that there's the karma toll, using downvotes to mean anything other than ‘I don't think this comment or post belongs here’ is a bad idea. Also, now we have poll syntax.

I'd want to vote comments in this thread according to whether they're interesting or boring, regardless of whether I agree with them.

I really wish there was a way to suspend the toll for irrationality game posts.

This could have been done by each commenter creating a poll in the comment, leaving normal voting for interest.

Yupp. That one. Maybe the OP could change the title to include 'irrationality' (or add a tag) to stay in the original spirit.
3
My understanding is that this is explicitly meant not to be quite the same thing as the Irrationality Game. Specifically, in the IG the idea is to find things you think are more likely to be true than the LW consensus reckons them; here (I think) the idea is to find things you think are actually likely to be true despite the LW consensus.

As long as you get the gist (think in probability instead of certainty, update incrementally when new evidence comes along), there's no additional benefit to learning Bayes' Theorem.
Meta: It is easy to take a position that is held by a significant number of people and exaggerate it to the point where nobody holds the exaggerated version. Does that count as a contrarian opinion (since nobody believes the exaggerated version that was stated) or as a non-contrarian opinion (since people believe the non-exaggerated version)?
(Edit: This is not intended to be a controversial opinion. It's meta.)
4
My understanding is that the idea is to post opinions you actually hold that count as contrarian.
5
I was mostly thinking of the one about open borders. Hardly anyone thinks that open borders would destroy civilization, but that's an exaggerated version of "open borders are a bad idea". If I disagree that they would destroy civilization, but I agree that they are a bad idea, should I treat it as a contrarian opinion or a non-contrarian opinion?
Furthermore, it sounds like that would not qualify as "opinions you actually hold" unless the poster thought it would destroy civilization.
4
Really? I consider it obvious for a sufficiently strong definition of "open boarders".
Also it wouldn't completely destroy civilization because the open boarders aspect would collapse before all of civilization did.

The truth of a statement depends on the context in which the statement is made.
6
I think this is uncontroversial if taken as referring to the following two things:
* The meaning of a statement depends on its context. (E.g., "that's a red herring" might mean different things when pointing at a net full of fish and when listening to a debate.)
* A statement may contain indexical terms whose reference varies with time or place or whatever. (E.g., one person may say "I have a headache" and another "I do not have a headache" and there is no contradiction.)
and controversial but not startlingly so if taken as referring to the following:
* Some statements implicitly refer to a particular set of goals, values, etc. and different systems of values may be active in different contexts. (E.g., if one person says "Apple stock is a good investment" and another "Apple stock is a bad investment" there may be no contradiction; they may just have different goals and therefore different attitude to volatility, correlation with other tech stocks, etc. Or if one person says "Meringue is delicious" and another "Meringue is disgusting" they may be describing their own tastes as much as the characteristics of meringue as such.)
Are you intending to state something more than those?
1
There are some people who believe that there something called objective reality and you can check whether a statement is true in objective reality.
I say that a statement might be true in context A but false in context B.
2
I don't think you answered my question. (Perhaps because you think it's meaningless or embodies false presuppositions or something.)
Aside from the facts that (1) the same utterance can mean different things in different contexts, (2) indexical terms can refer differently in different contexts, and (3) different values and preferences may be implicit in different contexts, do you think there are further instances in which the same statement may have different truth values in different contexts?
(I think the boundary between #1 and "real" differences in truth value is rather fuzzy, which I concede might make my question unanswerable.)
Some concrete examples may be useful. The following seem like examples where one can avoid 1,2,3. Are they ones where you think the truth value might be context-dependent, and if so could you briefly explain what sort of context differences would change the truth value?
* Simple statements about small integers. "1234 times 4321 = 5332114". Obviously could mean something else if you're talking to someone whose system of notation swaps the glyphs for 3 and 4, or who uses "times" to mean what we mean by "plus"; but beyond that?
* Empirical statements with all terms near to being typical cases. "Freshly spilled human blood is usually red." Obviously could mean something different in an alternate world where "human" denotes some other species or in a community where "red" is used to denote short-wavelength rather than long-wavelength visible light; but beyond that?
-1
The fact that you claim to get 7 digits of accuracy by multiplying two 4 digit numbers is very questionable. If I would go after my physics textbook 1234 times 4321 = 5332000 would be the prefered answer and 1234 times 4321 = 5332114 would be wrong as the number falsely got 3 additional digits of accuracy.
A more exotic issue is whether times is left or right associative. The python pep on matrix multiplication is quite interesting. It goes through edge cases such as whether matrix multiplication is right or left associative.
Red is actually a quite nice example. Does it mean #FF0000? If so, the one that my monitor displays? The one that my printer prints? On is red not a property of an object but a property of the light and it means light with a certain wavelength? That means that if I light the room a certain way the colors of objects change. If it's a property of the object, what's when the object emits red light but doesn't reflect it? Alternatively red could also be something that triggers the color receptors of humans in a specific way. In that case small DNA changes in the person who perceives red alter slightly what red means. But "human red" is even more complex because the brain does comlex postprocessing after the color receptors have given a certain output.
If red means #FF0000 then is #EE0000 also red or is it obviously not red because it's not #FF0000? What do you do when someone with design experience and who therefore has many names for colors comes along and says that freshly spilled human blood is crimson rather than red? If we look up the color crimson you will find that Indiana University has IU crimson and the University of Kansas has KU crimson. Different values for crimson make it hard to decide whether or not the blood is actually colored crimson.
Depending on how you define red mixing it with green and blue might give you white or it might give you black.
I used to naively think that I can calculate the difference between two colors by
2
Multiplication: so this looks like you're again referring to meanings being context-dependent (in this case the meaning of "= 5332114"). So far as I can see, associativity has nothing whatever to do with the point at issue here and I don't understand why you bring it up; what am I missing?
Redness: yeah, again in some contexts "red" might be taken to mean some very specific colour; and yes, colour is a really complicated business, though most of that complexity seems to me to have as little to do with the point at issue as associativity has to do with the question of what 1234x4321 is.
So: It appears to me that what you mean by saying that statements' truth values are context-dependent is that (1) their meanings are context-dependent and (2) people are often less than perfectly precise and their statements apply to cases they hadn't considered. All of which is true, but none of which seems terribly controversial. So, sorry, no upvote for contrarianism from me on this occasion :-).
0
If you are in the object oriented paradigm 1234.times(4321) is something slightly different than 1234.times(4321)
In my map of the world I wouldn't formulate that statement, because you rate precision by an objective standard and I don't think that a single standard exists. Statements that people make are precisely the statements they make. My disagreement is about a fundamental issue and not simply about handling one example differently.
1
I guess you wanted one of those to be the other way around. In any case, that's commutativity not associativity, it has nothing to do with object orientation (you could equally say that times(1234,4321) and times(4321,1234) are different), and since it happens that multiplication of numbers is commutative it again seems like a total red herring.
I do? Please, tell me more about how I rate precision.
Which I think simply amounts to the fact that the same sentence may denote different propositions in different contexts, because meaning is context-dependent. Which I think is not at all controversial.
I may well be misinterpreting you, but in that case I think it's time for you to be clearer about what you mean. So far, all the examples we've had have been (so it seems to me) either (a) cases where meaning or reference is context-dependent but it's at least arguable that once the meaning is nailed down you have a proposition whose truth value is not context-dependent, or (b) just observations that life is complicated sometimes (September 1752, leap seconds, etc.) without any actual context-dependent proposition in sight.
As I remarked above, I'm not certain how precise one can make the distinction between context-dependent meaning and context-dependent truth value. But since (I think) intelligent thoughtful people are generally entirely unbothered by the idea of context-dependent meaning, any version of context-dependent truth value that can't be clearly distinguished from context-dependent meaning shouldn't be that controversial :-).
0
In python I can overwrite the times function of one element that means that different elements have slightly different times functions. As such it's important to know whether X times Y means that times is a function of the X or of the Y object.
But you might be right that associativity is not the right word.
When I see the word precision I see it has having a certain meaning that people at university taught me. You might mean something different with the term. What do you mean?
In the case of color my position lead to disagreement with other people on LW because I follow different heuristics about truth than other people.
There are many thoughtful people who put a lot of value in searching something like objective truth. Do you deny that proposition?
1
Nope. Because so far everything you've said seems perfectly compatible with "something like objective truth".
I appreciate that you consider yourself to be denying that any such thing is possible -- which is why I am interested in finding out exactly what it is you're claiming, and whether your disagreement with the seekers after objective truth is about more than terminology.
0
I certainly do make real life decision based on my views that I wouldn't make if I would seek objective truth. When making Anki cards, every one of my cards explicitly states the context in which a statement stands. Creating Anki cards forces you to think very hard about statements and how they can be true or false.
Barry Smith against Fantology might also be worth reading.
1
Again, perfectly consistent with holding that meaning rather than truth is context-dependent.
And, again, I appreciate that you would say (T) "Truth is context-dependent" rather than (M) "Meaning is context-dependent". What I'm trying to grasp is (1) whether you mean by (T) more than someone else might mean by (M) and (2) whether your reasons for holding (T) are good reasons for holding (T) rather than (M).
This doesn't seem to me to have much to do with whether there are objective truths; it's about what sort of things, and relationships between things, and qualities, and so forth, there are. Holding that some truths aren't well expressible in terms of first-order predicate calculus isn't the same thing as holding that there are no truths.
0
If you at most people's Anki cards they don't contain explicit references to context. There are reasons why that's the case. It comes from the way those people think about the nature of knowledge.
I haven't said that there are no truths but that truths are context dependent. On of the issues of first-order predicate calculus is that it doesn't contain information about context.
0
One of my pet theories is that colour terms are implicitly indexical, so I dont think that what you say departs from the uncontroversial cases.

Let's say you want to seed an AGI with knowledge.
Some humans get some gene therapy that turns their blood blue. Then the AGI reasons that those entities aren't humans anymore and therefore don't need to be treated according to the protocol for treating humans. Or it get's confused with other issues about 'red'.
The only way around this is to specifically tell the FAI the context in which the statement is true. If you look at Eliezers post about truth you won't find a mention that context is important and needs to be passed along.
It's just not there. It's not a central part of his idea of truth. Instead he talks about probabilities of things being true.
None of my Anki cards has "this is true with 0.994%" probability. Instead it has a reference to context. That's because context is more important than probability for most knowledge. In the framework that Eliezer propagates probability is of core importance.
2
That isn't an example where a truth value depends on context, it's an example where making the correct deductions depends on the correct theoretical background.
However I agree that quantifying what you haven't first understood is pointless.
0
The thing is that having freshly spilled blood turn out to be red is neither sufficient nor necessary to be a human.
For the AGI it's necessary to treat sentence that tell the AGI sufficient or necessary conditions from sentences that tell the AGI about observations. Those two kind of statements are different contexts.
We have plenty of smart people on LW and plenty of people who use Anki but we don't have a good Anki deck that teaches knowledge about rationality. I think that errors in thinking about knowledge and the importance of context prevent people from expressing their knowledge about rationality explicitly via a medium such as Anki cards.
I think that has a lot to do with people searching for knowledge that objectively true in all contexts instead of focusing on knowledge that's true in one context. If you switch towards your statement just being true in one context that you explicitly define you can suddenly start to say stuff.
When it comes to learning color terms I did have LW people roughly saying: "You can't do this, objective truth is different. Your monitor doesn't show true colors".
1
That was probably me. You can define colors objectively, it's not hard. That includes colors in a digital image given a color space. However what you see on your computer monitor may (and does) differ considerably from the reference standard for a given color.
0
You can decide for some definition. But that's not the core of the issue. The core of the issue is that I can write decent Anki cards given my context-based truth which I couldn't write otherwise if I wouldn't think the context based frame.
As I said above deciding for a reference standard isn't a trivial decision. The W3C standard is for example pretty stupid when it defines distance between colors. I also can't easily find a defined reference standard for what #228B22 (forestgreen) is. Could you point me to a standard document that defines "the reference standard"?
1
The core issue is whether your argument amounts to context based truth, or context based meaning.
1
Sure.

If you are crediting an AI with the ability to undersand plain English, you are crediting it with a certain amount of ability to detect context in the first place.

I haven't said anything about plain English. If you look at Cyc's idea of red I don't think you find the notion that red means different things based on context.

The full meaning of a statement depends on the context in which it is made.
3
How is that a contrarian statement? Obviously natural language is heavily context-dependent. So what exactly do you mean when you say that?
1
I'm not saying something just focused on natural language. I think it's true for any statements.
If you look at http://lesswrong.com/lw/eqn/the_useful_idea_of_truth/ there's no mention of context and how a statement can be true in context A but false in context B.
2
Just to clarify, you mean that there is a context in which "0 = 1" is a true statement, which is not tantamount to redefining "0", "=", or "1"? That is, in some alternate universe, "0 = 1" is consistent with the axioms of Peano arithmatic?
0
In most cases the numbers that normal humans use don't follow strictly the axioms of Peano. Most of the time the dates of a month follow Peano. Most of the time the day after September 2 is September 3. But not always.
On a computer you can't store every natural number as specified by Peano with common integers.
If you start counting apples and get really many apples you suddenly have a black hole and no apples anymore.
I don't know enough about the philosophy of math to get really deep by we had lately someone writing posts about constructivist math that also contained the notion that there are no absolute mathematical truths.

In that case, it sounds like you're just not a math realist. There are plenty of people who believe that Peano arithmetic somehow exists on its own. Or possibly people who have a different definition of "exist" from me. It's hard to tell the difference. But I don't think disagreeing with that is all that unusual.

I'm not good enough at math to confidently answer that question. I'm good enough at math that I think that people want to debate whether or not something like infinite small numbers exist.

Happiness is actually far more important than people give it credit for, as a component of a reflectively coherent human utility function. About two thirds of all statements made of the form, "$HIGHER_ORDER_VALUE is more important than being happy!" are reflectively incoherent and/or pure status-signaling. The basic problem that needs addressing is of distinction between simplistic pleasures and a genuinely happy life full of variety, complexity, and s...

What do you mean by "pure signalling"? You evolve to show the signal. Whether the actual metal process that makes the signal is a cost-benefit analysis on lying or actually believing what you say doesn't matter. Does evolving to automatically feel more empathy for children as a way of signalling that you'd be a good parent count as "pure signalling"?
the United States prison system is a tragedy on par or exceeding the horror of the Soviet gulags. In my opinion the only legitimate reason for incarcerating people is to prevent crime. The USA currently has 7 times the OECD average number of prisoners and crime rates similar to the OECD average. 6/7 of the Us penial system population is a little over 2 million people. If we are unnescesarily incarcerating anywhere close to 2 million people right now then the USA is a morally hellish country.
note: Less than half of the inamtes in the USa are there for drug related charges. It is very close to 50% federally but less at the state level. Immediately pardoning all criminals primarily gets us to 3.5 times the OECd average.
4
This seems close to the (liberal) mainstream. Why do you think it is contrarian on LW?
7
I do not think most people consider this a problem on the par of the Soviet Gulag. Though possibly I am wrong.

The problem with the Soviet Gulag wasn't so much its size, but rather the whole system it was part of and things which got you sent to it.

Is your claim that they're in prison for crimes they didn't commit, or that we should let more crimes go unpunished?
6
I'm not the OP, but I'll throw a quote into this thread:
2
So which crimes would you take off the books and what percent of prisoners would that remove?
6
We can start with the drug war, things like civil forfeiture, and go on from there. You might be interested in this book.
The problems with the US criminal justice system go much deeper than just the abundance of laws, of course.
3
Civil forfeiture doesn't fill prisons.
The problem with having to many felonies is not that prisons get filled with people being punished for silly things, it's that the people who do get punished for silly things tend to correlate with the people actively opposing the current administration.
1
There are a LOT of problems with having too many felonies, but that's a large discussion not quite in the LW bailiwick...
1
Agreed, but the discussion was about there supposedly being too many people in prison.
0
False dichotomy, It's about sentence length, eg three strikes.
1
So if we reduced sentences what effect do you think that would have on crime rates? Remember three strikes was passed in response to crime rates being too high.
2
Drastically increasing sentences didn't drastically reduce crime, so...
Comparable countries have lower crime rates and lower prison populations, so they must be doing something right.
You don't have to keep moving the big lever up and down: you can get Smart on Crime.

Well, the crime did fall. Whether it was due to increased sentences or something else is still being debated.
They also have fewer people from populations with high predisposition to violence (and yes, I mean blacks).

Provably-secure computing is undervalued as a mechanism for guaranteeing Friendliness from an AI.
6
I'm not sure what you mean by provably-secure, care to elaborate?
It sounds like it might possibly be required and is certainly not sufficient.
1
Provably-secure computing is a means by which you have a one-to-one mapping between your code and a proof that the results will not give you bad outcomes to a certain specification. The standard method is to implement a very simple language and prove that it works as a formal verifier, use this language to write a more complex formal verifying language, possibly recurse that, then use the final verifying language to write programs that specify start conditions and guarantee that given those conditions outcomes will be confined to a specified set.
It seems to be taken for granted on LW and within MIRI that this does not provide much value because we cannot trust the proofs to describe the actual effects of the programs, and therefore it's discounted entirely as a useful technique. I think it would substantially reduce the difficulty of the problem which needs to be solved for a fairly minor cost.

I don't think it's true, that it's generally considered not useful. One of MIRIs interviews was with one person engaged into provably-secure computing and I didn't see any issues in that post. It's just that provably-secure computing is not enough when you don't have a good specification.
Bitcoin and a few different altcoins can all coexist in the future and each have significant value, each fulfilling different functions based on their technical details.

That doesn't seem especially contrarian to me, given the base premise that cryptocurrency has legs in the first place. At the very least, it seems obvious that easy-to-trace and difficult-to-trace transaction systems have different and complementary niches.

I thought it was contrarian, but perhaps I am wrong? I've seen plenty of 'every altcoin is worthless, dont ever buy any' comments in discussions in the past.

I think it's a small (but loud and motivated) group of bitcoin fans that think that, with most people taking your position (at least conditional on the statement that any cryptocurrency is useful at all).
Can you see why the rope in my example would break or stretch, even if we're moving it very very slowly?
Your example isn't relevant for this discussion.
