There is no t coordinate, and no global now sweeping across the universe. Events do not happen in the past or the present or the future, they just are. But there may be a certain... asymmetric locality of relatedness... that preserves "cause" and "effect", and with it, "therefore"

Not to trivialize this, but Phillip Fry helps me think about it, by going back in time and being his own grandfather:

http://en.wikipedia.org/wiki/Roswell_That_Ends_Well

for him, whether he was prior to his father is an unanswerable question, but the story is causally consistent.

Essentialism also seems very prominent in human pleasure, per "how pleasure works" book.

As far as supernatural theories, I am in an interesting position as far as taking some meditation training from a martial arts teacher; on one hand I (surely hope!) am not "aligning meridians of the body" while doing the breathing exercises, on the other hand I don't want to dismiss this incorrect "model" too early as it might be of further usefulness, given that these systems tend to be very ancient.

-men and women: men aren't supposed to dress like women and vice versa.

agreed, support your theory

-fish and mammals

yes, probably wrong way to phrase it, but I agree about the essentialism of "fish with scales" being "fishy fish" - that's a very sharp observation, actually.

I believe certain investors used some sentiment as counter-indicators. Jim Cramer comes to mind.

  • wool and flax - Yes
  • men and women - Huh?
  • fish and mammals - Sort of (some people do not eat milk and fish with same utensils, but it's not from the Bible as far as I can tell) Additionally -
  • mixing plant species (via grafting) - Yes, a major support for your point

-men and women: men aren't supposed to dress like women and vice versa. -fish and mammals: takes some unpacking and was probably the wrong way to phrase it. The fish you can eat should have scales and fins -- that sort of points to "good" fish being especially "fishy" fish. Fish that are kind of not like fish are not okay.

I suspect it's also difficult for Julian (or pretty much anybody) to estimate these things; I guess intelligent people will just have to make best guesses about this type of stuff. In this specific case a rationalist would be very cautious of "having an agenda", as there is significant opportunity to do harm either way.

To be fair, I think the parent of the downvoted comment also has status implications:

I think you're nitpicking to dodge the question

It's a serious accusation hurled at the wrong type of guy IMO - Vladimir probably takes the objectivity award on this forum. I think his response was justified and objective, as usual.

When someone says "look, here is this thing you did that led to these clear problems in reality" and the person they're talking to answers "ah, but what is reality?" then the first person may reasonably consider that dodging the question.

whether the decision is correct (has better expected consequences than the available alternatives), not whether it conflicts with freedom of speech.

Sounds like a good argument for WikiLeaks dilemma (which is of course confused by the possibility the government is lying their asses off about potential harm)

1Vladimir_Nesov
The question with WikiLeaks is about long-term consequences. As I understand it, the (sane) arguments in favor can be summarized as stating that expected long-term good outweighs expected short-term harm. It's difficult (for me) to estimate whether it's so.

I suspect it's for the same reason I occasionally litter by accident and not pick it up; it's a negative externality but the cost of self monitoring all the time is greater. I'd get worried if it goes over a (small) threshold. People like the communication for non-informational reasons and occasionally speech-litter.

[5] Thus, to extend this conjecturally toward our original question: when someone asks "Is the physical world 'real'?" they may, in part, be asking whether their predictive models of the physical world will give accurate predictions in a very robust manner, or whether they are merely local approximations. The latter would hold if e.g. the person: is a brain in a vat; is dreaming; or is being simulated and can potentially be affected by entities outside the simulation.

I think historically, the phenomenon described must have played some role in the evolution of intelligence. So why should I retract it?

I do not think the article suggests any non-toy scenario where such situations might have reasonably arisen.

My personal favorite reason for "why are we not more intelligent species" is that the smart ones don't breed enough :)

xamdam100

So I actually read the book; while there is a little "dis" in there, but the portrait is very partial: "Nate Caplan, my IQ is 160" of "OverpoweringFalsehood.com" is actually pictured as the rival of the "benign SuperIntelligence Project" (a stand-in for SIAI I presume, which is dissed in its own right of course). I think it's funny flattering and wouldn't take it personally at all, doubt Eliezer would in any case.

BTW the book is Ok, I prefer Egan in far-future mode than in near-future.

variation in SIDS across socio-economic spectrum suggest infanticide is quite common in our culture.

25% of pregnancies end in miscarriage. Miscarriage is common...The hospital procedure is routine and not attended with the same kind of reverence as death usually is.

Infant death rate was around 20% (in Paris!) when they invented incubators. I wonder if their attitude to infant death was similar to our re: miscarriage.

That was, I believe, implicit in the original post. The reason that it's scary is that it doesn't just apply to scratching a rash, it also applies to doing hard drugs. Reference points, as used by default, make it very easy to throw your life away. That's what makes it scary.

"Jam now" is a necessary condition, not a sufficient one. If I decide to, say, learn Spanish, then I expect every hour spent on the task, including the first one, to pay a perceptible return.

The descriptive math part was very good, thanks - and that's why I resisted downvoting the post. My problem is that the conclusion omits the hugely important factor that categories are useful for specific goals, and the kind of techniques you are suggesting (essentially unsupervised techniques) are context-free.

E.g. is a dead cow more similar to a dead (fixed from 'live') horse or to a live cow? (It clearly depends what you want to do with it)

2kpreid
Your example doesn't quite make sense to me. Did you mean “is a dead cow more similar to a dead horse or to a live cow”, or ...?
6[anonymous]
That's a good point. I tend to find techniques attractive when they're generalizable, and context-free, unsupervised techniques fit the bill. You can automate them. You can apply them to a range of projects. But you're right -- sometimes specific knowledge about a specific application matters, and you can't generalize it away.

Great post, thanks.

I try to remember my heroes for the specific heroic act or trait, e.g. Darwin's conscientious collection of disconfirming evidence.

So if, as Aristotle claimed, excellence is not an act but a habit, perhaps heroism is not a habit but an act?

No, I am not aware of any facts about progress in decision theory

As far as the dragon, I was just pointing out that some minds are not trainable, period. And even if training works well for some intelligent species like tigers, it's quite likely that it will not be transferable (eating trainer, not ok, eating an baby, ok).

0MatthewB
Yes, I have read many of the various Less Wrong Wiki entries on the problems surrounding Friendly AI. Unfortunately, I am in the process of getting an education in Computational Modeling and Neuroscience (I was supposed to have started at UC Berkeley this fall, but budget cuts in the Community Colleges of CA resulted in the loss of two classes necessary for transfer, so I will have to wait till next fall to start... And, I am now thinking of going to UCSD, where they have the Institute of Computational Neuroscience (or something like that - It's where Terry Sejnowski teaches), among other things, that make it also an excellent choice for what I wish to study) and this sort of precludes being able to focus much on the issues that tend to come up often among many people on Less Wrong (particularly those from the SIAI, whom I feel are myopically focused upon FAI to the detriment of other things). While I would eventually like to see if it is even possible to build some of the Komodo Dragon like Superintelligences, I will probably wait until such a time as our native intelligence is a good deal greater than it is now. This touches upon an issue that I first learned from Ben. The SIAI seems to be putting forth the opinion that AI is going to spring fully formed from someplace, in the same fashion that Athena sprang fully formed (and clothed) from the Head of Zeus. I just don't see that happening. I don't see any Constructed Intelligence as being something that will spontaneously emerge outside of any possible human control. I am much more in line with people like Henry Markham, Dharmendra Modha, and Jeff Hawkins who believe that the types of minds that we will be tending to work towards (models of the mammalian brain) will trend toward Constructed Intelligences (CI as opposed to AI) that tend to naturally prefer our company, even if we are a bit "dull witted" in comparison. I don't so much buy the "Ant/Amoeba to Human" comparison, simply because mammals (almost all

Taking UDT Seriously

Can you post this in the discussion area?

xamdam10

Thanks.

The posts (at least the second one) seem to point that symbolic reasoning is overstated and at least some reasoning is clearly non-symbolic (e.g. visual).

In this context the question is whether the symbolic processing (there is definitely some - math, for example) gave pre-humans the boost that allowed the huge increase in computing power, so I am not seeing the contradiction.

2Perplexed
Speech is a kind of symbolic processing, and is probably an important capability in mankind's intellectual evolution, even if symbolic processing for the purpose of reasoning (as in syllogisms and such) is an ineffectual modern invention.

Would being seen be an advantage for them? (answering question with a question, still...)

Freud once said that Jung was a great psychologist, until he became a prophet.

xamdam110

calling this "symbolic processing" assumes a particular theory of mind, and I think it is mistaken

Interesting. Can you elaborate or link to something?

0timtyler
Susan Blackmore argues that what originally caused the "huge increase in optimization power" was memes - not symbolic processing - which probably started up a bit later than the human cranium's expansion did.
cousin_it130

I'm not Eliezer, but will try to guess what he'd have answered. The awesome powers of your mind only feel like they're about "symbols", because symbols are available to the surface layer of your mind, while most of the real (difficult) processing is hidden.

It is going to be next to impossible to solve the problem of "Friendly AI" without first creating AI systems that have social cognitive capacities. Just sitting around "Thinking" about it isn't likely to be very helpful in resolving the problem.

I am guessing that this unpacks to "to create and FAI you need some method to create AGI. For the later we need to create AI systems with social cognitive capabilities (whatever that means - NLP?)". Doing this gets us closer to FAI every day, while "thinking about it" doesn... (read more)

-1MatthewB
Yes, that is close to what I am proposing. No, I am not aware of any facts about progress in decision theory that would give any guarantees of the future behavior of AI. I still think that we need to be far more concerned with people's behaviors in the future than with AI. People are improving systems as well. As far as the Komodo Dragon, you missed the point of my post, and the Komodo dragon just kinda puts the period on that: "Gorging upon the stew of..."

Simons is an AI researcher? News to me. Clearly his fund uses machine learning, but there is an ocean between that and AGI (besides plenty of funds use ML also, DE Shaw and many others).

Status, say, is the analogy of board position- it only leads to higher genetic fitness on average in some broad way, but it's a cheap and effective heuristic for doing so, just like good board position is a cheap and effective (but not guaranteed!) heuristic for winning at chess

Yep, basically what I was getting at.

The extreme is uninformative, that's why I was asking if you came to any heuristics about finding and optimal point. Clearly there are benefits to muscle, besides status: strength and increased metabolism (the way I understand it is you actually have to exercise less with weights than with aerobics to stay in shape). Too much is likely to lead to injury and possibly other problems (possibly caused by extreme blood pressure during heavy lifting).

My personal conclusion is that bodyweight exercises are pretty safe, though I do use weights where bodyweight alternatives are too complicated or require annoyingly many reps.

0itsunder9000
Too many people run marathons and lift heavy weights for me not too say them. I don't think that increased strength and increased metabolism are great benefits now. There are few instances in today's world where strength matters, and increased metabolism is really only important if you really like food, or are a competitive food eater. Beyond not being obese and being able to play a game of pick up basketball with the guys, I am not convinced that exercise really means anything, beyond increasing status to some groups of people. I would simply recommend doing the type of exercises that will make your body type appeal to those who you want to impress, or get along with, that don't have a high risk of injury(unless you like impressing the risky crowd, up to you)

I use weights a bit, and since you are on a rationalist site I'd ask this question: where is the point where lifting unusually heavy things contributes more to the destruction of the body than to its maintenance?

2itsunder9000
Well, after researching this topic for several years, i can condense it into this. Lifting unusually heavy things, and running unusually long distances do more long term harm than good. Think doing heavy squats, and running marathons. The only benefit I can think of for doing heavy lifts, is to impress to bros, and get buff for a party fast, while taking a semi-legal supplement. heavy lifting does not have long term advantages.

Don't know a direct answer to your question, but I think these types of books (Torah is the one I am very familiar with) are best deconstructed by historians, as they were not all written at once (at least this is the case for Torah).

And where is the markup help in this blog? I can't seem to find it and it frustrates the hell out of me when I'm commenting usual posts.

Look at the Help link bottom right of the comment box.

1Raw_Power
Thank you for pointing that link out. I loked and looked... and missed what was right in front of me. And yes, the comments here on the Torah and New Testament have given me pointers towards how this should be done properly. Obviously the historical context is very useful for discussing why one set of rules or another was established, what was the spirit of the rule and what impact it had in contrast with the presilamic environment, or for commenting on the incendiary antisemitic fragments and how in fact their scope might be so narrow as to only apply to the Jews back then. Muslims, like Christians, can and will go out of their way to interpret verses in a way that favours their actual, current values or beliefs. It is also interesting to see how the Qran builds upon the pre-existing narrative of the Torah and Gospel, but dismisses them as corrupted and altered by the Powers that Be (specifically the priesthood and ruling classes) to suit their own interests, and presents its own retelling of the events (when it bothers retelling stuff instead of cryptically, elliptically and confusingly mentioning a couple of names). However, the Qran wasn't written all at once either, but it was written by one single man, in sporadic bursts, over the course of twenty years. But what I want to study here are the bits of the Qran that are abot faith and the afterlife, not about rules which, all things considered, were remarkably sensible, coherent, cohesive and progressive by their day's standards. See the comments to the next post.
