Pure curiousity question: What is the general status of UDT vs. TDT among yall serious FAI research people? MIRI's publications seem to exclusively refer to TDT; people here on LW seem to refer pretty much exclusively to UDT in serious discussion, at least since late 2010 or so; I've heard it reported variously that UDT is now standard because TDT is underspecified, and that UDT is just an uninteresting variant of TDT so as to hardly merit its own name. What's the deal? Has either one been fully specified/formalized? Why is there such a discrepancy between MIRI's official work and discussion here in terms of choice of theory?

Comment author: Wei_Dai 25 April 2014 04:31:24AM *  8 points [-]

MIRI's publications seem to exclusively refer to TDT

Why do you say that? If I do a search for "UDT" or "TDT" on intelligence.org, I seem to get about an equal number of results.

people here on LW seem to refer pretty much exclusively to UDT in serious discussion

This seems accurate to me. I think what has happened is that UDT has attracted a greater "mindshare" on LW, to the extent that it's much easier to get a discussion about UDT going than about TDT. Within MIRI it's probably more equal between the two.

that UDT is just an uninteresting variant of TDT so as to hardly merit its own name

As I recall, Eliezer was actually the one who named UDT. (Here's the comment where he called it "updateless", which everyone else then picked up. In my original post I never gave it a name but just referred to "this decision theory".)

Has either one been fully specified/formalized?

There has been a number of attempts to formalize UDT, which you can find by searching for variations on "formal UDT" on LW. I'm not aware of a similar attempt to formalize TDT, although this paper gives some hints about how it might be done. It's not really possible to "fully" specify either one at this time because both need to interface with a to-be-discovered solution to the problem of logical uncertainty, and at this point we don't even know the type signature of such a solution. In the attempts to formalize UDT, people either make a guess as to what the type signature is, or side-step the problem by assuming that all relevant logical facts can be deduced by the agent.

Comment author: Vulture 25 April 2014 01:05:45PM 1 point [-]

Thanks! This is exactly the kind of answer I was hoping for. A lot of it was what I had sort of deduced from looking at MIRI docs and stuff, but having it laid out explicitly seems to have clicked the missing elements into place and I feel like I understand it much better now.

Comment author: Manfred 25 April 2014 05:25:09PM *  2 points [-]

I'm not serious, but I'd say that there's little actual use of TDT because it requires us to solve the difficult problem of finding the right causal and logical structure of the problem - this can be handwaved in by the user, but doing that feels awkward. Folk-UDT ("just execute the best strategy") is sufficient for most purposes, both in application and in e.g. trying to understand logical uncertainty.

On the other hand, using causal structure is what lets us consider hypotheticals properly - so TDT will not have some issues that typical-UDT does with hypotheticals about its own actions. On the mutant third hand, TDT's solution of adding logical nodes to the causal structure might just be a simplification of something deeper, so it's not like we (us non-serious decision-theory dilettantes) should put all our eggs in one basket.

Comment author: Douglas_Knight 25 April 2014 07:55:25PM 1 point [-]

What is an example of an issue that UDT has with hypotheticals that TDT does not?

Comment author: Manfred 25 April 2014 08:48:46PM *  1 point [-]

The 5 and 10 problem is basically what happens when your agent asks "what are the logical implications if 5 is chosen?" rather than "If we do causal surgery such that 5 is chosen, what's the utility?"

There are other ways to avoid the 5 and 10 problem, but I think they're less general than using causality.

I get confused when people use language that talks about things like "fairness", or whether people are "deserving" of one thing or another. What does that even mean? And who or what is to say? Is it some kind of carryover from religious memetic influence? An intuition that a cosmic judge decides what people are "supposed" to get? A confused concept people invoke to try to get what they want? My inclination is to just eliminate the whole concept from my vocabulary. Is there a sensible interpretation that makes these words meaningful to atheist/agnostic consequentialists, one that eludes me right now?

Comment author: IlyaShpitser 22 April 2014 05:38:05PM *  5 points [-]

I am with Stanislaw Lem -- it's hard to communicate in general, not just about fairness. I find so many communication scenarios in life resemble first contact situations..

Comment author: Alsadius 22 April 2014 04:19:14AM 8 points [-]

It's not a theistic concept - if anything, it predates theology(some animals have a sense of fairness, for example). We build social structures to enforce it, because those structures make people better off. The details of fairness algorithms vary, but the idea that people shouldn't be cheated is quite common.

Comment author: fubarobfusco 22 April 2014 04:06:18PM 9 points [-]

Here are some things people might describe as "unfair":

  • Someone shortchanges you. You buy what's advertised as a pound of cheese, only to find out at home that it's only four-fifths of a pound; the storekeeper had their thumb on the scale to deliberately mis-weigh it.
  • Someone passes off a poor-quality item as a good one. You buy a sealed box of cookies, only to find out that half of them are broken and crumbled due to mishandling at the store.
  • Someone entrusted with a decision abuses that trust to their advantage. The facilities manager of a company doesn't hire the landscaping company that makes the best offer to the company, but instead the one that offers the best kickback to the facilities manager.
  • Someone uses a position of power to take something that isn't theirs; especially when the victim can't do anything about it. A boy's visiting grandmother gives him $50 to buy a video game for his birthday; but as soon as the grandmother has left, the boy's mother takes the money away and uses it to buy liquor for herself.
  • Someone abandons a responsibility, leaving it to others to cover. Four people go out to dinner together; and the bill comes to $100. One person excuses himself "to go to the restroom," but doesn't come back, so the others have to pay his share of the bill as well as their own.
  • Someone takes advantage of a person's weak or ignorant position. A taxi driver, knowing that a tourist doesn't know the city, takes a deliberately circuitous route to run up the meter.
  • Someone uses asymmetrical information to deprive others of a stronger negotiating position. An employer tells each of her employees individually that they are poor performers, easily replaceable, and unlikely to get a raise; so that they do not realize that together they are not easily replaceable and that by collective bargaining they could negotiate for higher wages.
  • Someone breaks agreed-upon rules to take something of value. A poker player uses a trick to put a card into play that wasn't dealt to him — the classic "ace up the sleeve" — in order to win money that another player would have won.
  • Someone entrusted to do a good job instead does a bad job in order to gain an advantage some other way. A star sports player deliberately plays poorly so his team will lose a game they are strongly favored to win, allowing people who have bet against his team to win big.
  • Someone gets away with breaking the rules by making outside arrangements with those responsible for enforcing them. By donating to the "police charitable fund," you get a bumper sticker that makes it less likely the police will pull you over if you break the traffic laws.

What sorts of things do you see in common among these situations?

Comment author: Lumifer 22 April 2014 04:23:10PM 13 points [-]

What sorts of things do you see in common among these situations?

Your list seems a bit... biased.

Let's throw in a couple more situations:

  • A homeless guy watches a millionaire drive by in a Lamborghini. "That's not fair!" he says.
  • An unattractive girl watches an extremely cute girl get all the guys she wants and twirl them around her little finger. "That's not fair!" she says.
  • A house owner learns that his house will be taken away from him under an eminent domain claim by the state which wants a developer to build a casino on the land. "That's not fair!" he says.
  • A union contractor is undercut on price by a non-union contractor. "That's not fair!" he says.
Comment author: blacktrance 22 April 2014 05:32:42PM 8 points [-]

While people say "That's not fair" in the above examples and in these, it seems there are two different clusters of what they mean. In the first group, the objection seems to be to self-serving deception of others, particularly violation of agreements (or what social norms dictate are implicit agreements). Your examples don't involve deception or violation of agreements (except perhaps in the case of eminent domain), and the objection is to inequality. I find it strange that the same phrase is used to refer to such different things.

Comment author: Kaj_Sotala 23 April 2014 07:24:43AM *  11 points [-]

I think you could say that in both groups, people are objecting because society is not distributing resources according to some norm of what qualities the resource distribution is supposed to be based on.

In the first group of examples, people are deceiving others and violating agreements, and society says that people are supposed to be rewarded for honest behavior and keeping agreements.

For the second group of examples:

  • The homeless person example is a bit tricky, since there are multiple different norms that they might be appealing to, but suppose that the homeless person used to be a hard worker before he got laid off and lost his home. The homeless person may then be objecting that society is supposed to reward a willingness to put in hard work, whereas he doesn't perceive the millionaire as having worked equally hard. Or, the homeless person may think that society should provide some minimum level of resources to everyone, and the fact that he has nothing while another person has millions demonstrates a particularly blatant violation of this rule.
  • There's a social ideal saying that people should be rewarded for their "internal" characteristics (like honesty) rather than "external" ones (like appearance), so the unattractive girl is objecting to the attractive girl being rewarded for something she's not supposed to be rewarded for.
  • The house owner is objecting because we usually think that people should be allowed to keep the property they have worked to have, and the eminent domain claim is violating that intuition.
  • The union contractor is complaing because he thinks that being unionized provides benefits for the profession as a whole, and that the non-union contractor is getting a personal benefit while defecting against the rest of the profession.

Regardless of what your ideal society looks like, creating it probably requires consistently maintaining some algorithm that rewards certain behaviors while punishing others. Fairness violations could be thought of as situations where the algorithm doesn't work, and people are being rewarded for things that an optimal society would punish them for, or vice versa.

You could also say that in both groups, there is actually an implicit agreement going on, with people being told (via e.g. social ideals and what gets praised in public) that "if you do this, then you'll be rewarded". If you buy into that claim, then you will feel cheated if you do what you think you should do, but then never get the reward.

Of course, the situation is made more complicated by the fact that there is no consistent, univerally-agreed upon norm of what the ideal society should be, nor of what would be the optimal algorithm for creating it. People also have an incentive to push ideals which benefit them personally, whether as a conscious strategy or as an unconscious act of motivated cognition. So it's not surprising that people will have widely differing ideas of what "fair" behavior actually looks like.

I find it strange that the same phrase is used to refer to such different things.

However looking at reality, the phrase is used in all these ways, isn't it?

Comment author: Eugine_Nier 22 April 2014 11:42:54PM 7 points [-]

As Bart Wilson mentions here, a century ago the word "fairness" referred exclusively to the first cluster. However, due to various political developments during the past century it has drifted and now refers to a confused mix of both.

Comment author: blacktrance 22 April 2014 06:31:32PM 2 points [-]

Indeed it is, which is evidence for the two different types of situations feeling similar to people.

Your list seems a bit... biased.

That's odd ... I was specifically trying to choose examples that would be relatively uncontroversial — cases of cheating, betrayal of trust, abuse of power, and so on; as opposed to cases of mere inequality of outcome.

Comment author: Lumifer 22 April 2014 06:23:34PM 5 points [-]

I was specifically trying to choose examples

That's a bias, isn't it? :-)

If you're choosing examples to construct a definition from, already having a definition in mind makes the exercise pointless.

If you choose examples of fraud and abuse of power you essentially force the definition of "unfair" be "fraud and abuse of power".

Comment author: fubarobfusco 22 April 2014 11:04:26PM 4 points [-]

Wow, and here I thought I'd be dinged for including such mildly politicized examples as the police one and the collective-bargaining one. Instead, I get dinged for not including a bunch of stuff likely to provoke a political foofaraw about class, gender, or eminent domain? Weird.

Okay, this is getting excessively meta. I'm done here.

Comment author: Torello 24 April 2014 03:09:54AM 2 points [-]

The sense of fairness evolved to make our mental accounting of debts (that we owe and are owed) more salient by virtue of being a strong emotion, similar to how a strong emotion of lust makes the reproductive instinct so tangible. This comes in handy because humans are highly social and intelligent and engage in positive-sum economic transactions, so long as both sides play fair... according to your adapted sense of what's fair. If you don't have a sharp sense of fairness other people might walk all over you, which is not evolutionarily adaptive. See "The Moral Animal" or "Nonzero" by Robert Wright, or the chapter "Family Vaules" in Steven Pinker's "How the Mind Works."

This sense of fairness may have been co-opted at other levels, like a religious or political one, but it's quite instinctual. Very young children have a strong sense of fairness before they could reason to it, just as they can acquire language before they could explicitly/consciously reason from grammar rules to produce grammatical sentences. It's very engrained in our mental structure, so I think it would take quite an effort to "wipe the concept."

Comment author: Lumifer 22 April 2014 03:03:53PM 2 points [-]

"Fairness" generally means one out of two things.

Either it's, basically, a signal of attitude -- to call something "fair" is to mean "I approve of it" -- or it is a rhetorical device in the sense of a weapon in an argument.

I think that people generally have gut ideas about what fairness entails, but they are fuzzy, bendable, and subject to manipulation, both by cultural norms and by specific propaganda/arguments.

Comment author: michaelkeenan 22 April 2014 08:29:30AM 1 point [-]

According to Moral Foundations Theory, fairness is one of the innate moral instincts.

According to Scott Adams, fairness was invented so children and idiots can participate in arguments.

I think we have a fairness instinct mostly so we can tell clever stories about why our desire for more stuff is more noble than greed.

Comment author: Eugine_Nier 22 April 2014 07:42:53AM *  1 point [-]

The word "fairness" has been subject to a lot of semantic drift during the past century. Here is a blog post by Bart Wilson, describing the older definition, which frankly I think makes a lot more sense.

It's a cultural norm. If someone constantly defects in prisoner dilemma he's violating the norm of fairness and deverses to be punished for doing so.

Except that in a lot of accusations of "unfairness" there is no obvious prisoner-dilemma-defection going on.

We sort of have an informal agreement of the proletarians not making a revolution and hanging the rich capitalists in return for society as a whole working in a way that makes everyone better of.

Rich bankers not fulfilling their side of working to make everyone in society better of is defecting from that agreement.

How would you apply that to Lumifer's second example?

Comment author: ChristianKl 24 April 2014 09:41:08AM 2 points [-]

The usual way groups of girls deal with this is to call the girl who actually twirls around a lot of guys around her little finger a slut. The punishment isn't physical violence but it's there.

I've been struggling with how to improve in running all last year, and now again this spring. I finally realized (after reading a lot of articles on lesswrong.com, and specifically the martial arts of rationality posts) that I've been rationalizing that Couch to 5k and other recommended methods aren't for me. So I continue to train in the wrong way, with rationalizations like: "It doesn't matter how I train as long as I get out there."

I've continued to run intensely and in short bursts, with little success, because I felt embarrassed to have to walk any, but I keep finding more and more people who report success with programs where you start slowly and gradually add in more running.

Last year, I experimented with everything except that approach, and ended up hurting myself by running too far and too intensely several days in a row.

It's time to stop rationalizing, and instead try the approach that's overwhelmingly recommended. I just thought it would be interesting to share that recognition.

It's time to stop rationalizing, and instead try the approach that's overwhelmingly recommended.

Have you considered not running as your primary exercise program? If you aren't specifically going for the performance of running, I would shelve it and instead cut calories (assuming you have extra weight to lose) and lift heavy things at the gym. Distance running is great for distance running.

I have been in multiple running groups and they are great for achieving goals like 26.2 miles, but after that, I wanted to optimize for looks and not for long distances (any more).

Unfortunately, I live in a rural area where gyms are hard to come by. I have enjoyed running for its own sake in the past, that's a part of why I want to get back into running shape, but I will try to add in some body weight exercises as well as my running.

You don't need a gym to exercise. Google up "paleo fitness", Crossfit is full of advice about how to build a basic gym in your garage, etc. etc.

Comment author: TylerJay 21 April 2014 05:53:51PM *  1 point [-]

The best general advice I can give you is:

  1. Be honest with yourself when determining your current abilities. There's no shame in building slowly. It just means you get to improve even more.

  2. Not every day is a hard day. There are huge benefits to varying your workouts. If you're running about the same distance each day you run, you're doing it wrong. Some days should be shorter, more intense intervals broken up by very slow jogs or walks, while other days should be "active recovery" days of short, slow runs, while other days you might go for distance and a sustained pace. Just to give an idea, even elite athletes will not usually do more than 2-3 hard (interval) days each week. You will want to start with 0 or 1.

  3. Watch your volume: Slowly increase your total miles / week over time. Make sure you start low enough not to get repetitive stress injuries.

I was once a fairly successful runner and have a lot of experience with designing training programs for both distance running and weightlifting. I'd be happy to help you design your running program or to look over your program once you do some research and put something together. Let me know!

Research on mindfulness meditation

Mindfulness meditation is promoted as though it's good for everyone and everything, and there's evidence that it isn't-- going to sleep is the opposite of being mindful, and a mindfulness practice can make sleep more difficult. Also, mindfulness meditation can make psychological problems more apparent to the conscious mind, and more painful.

The difficulties which meditation can cause are known to Buddhists, but have not yet known by researchers or the general public. The commercialization of meditation is part of the problem.

This isn't a question, just a recommendation: I recommend everyone on this site who wants to talk about AI familiarize themselves with AI and machine learning literature, or at least the very basics. And not just stuff that comes out of MIRI. It makes me sad to say that, despite this site's roots, there are a lot of misconceptions in this regard.

Comment author: Punoxysm 25 April 2014 02:31:47AM *  2 points [-]

Not so much a specific misconception, but understanding the current state of AI research and understanding how mechanical most AI is (even if the mechanisms are impressive) should make you realize that being a "Friendly AI researcher" is a bit like being a unicorn tamer (and I mean that in a nice way - surely some enterprising genetic engineer will someday make unicorns).

Edit: Maybe I was being a little snarky - my meaning is simply this: Given how little we know about what actual Strong AI will look like (And we genuinely know very very little), any FAI effort will face tremendous obstacles in transforming theory into practice - both in the fact that the theory will have been developed without the guidance that real-world constraints and engineering goals provide, and the fact that there is always overhead and R&D involved in applying theoretical research. I think many people here underestimate this vast difference.

Comment author: passive_fist 05 May 2014 08:45:29AM 0 points [-]

OK. I've seen a lot of people here say that Eliezer's idea of a 'Bayesian intelligence' won't work or is stupid, or is very different from how the brain works. Those familiar with the machine intelligence literature will know that, in fact, hierarchical Bayesian methods (or approximations to them) are the state of the art in machine learning, and recent research suggests they very closely model the workings of the cerebral cortex. For instance, refer to the book "Data Mining: Concepts and Techniques, 3rd edition" (by Han and Kamber) and the 2013 review "Whatever next? Predictive brains, situated agents, and the future of cognitive science" by Andy Clark: http://journals.cambridge.org/action/displayAbstract?fromPage=online&aid=8918803

The latter article has a huge number of references to relevant machine learning and cognitive science work. The field is far far larger and more active than many people here imagine.

How do I decide whether to get married?

  • My girlfriend of four years and I are both graduating college.
  • I haven't found employment yet, and she's returning home for work.
  • As near as I can tell, we're very compatible.

Pros

  • We are very fond of each other, get a lot of value out of each other's time.
  • We've been able to talk about the subject sanely.
  • Status
  • We agree on religion and politics.
  • Married guys make more on average, but the arrow of causality could point in either direction or come from something else.
  • Financial benefits

Cons

  • Negative Status associated with marrying young?
  • No jobs yet, no clear home or area to live in.
  • She sometimes gets mad at me for things I'm "just supposed to know" to do, not do, say, or not say. I'm not sure if she's right and I'm a jerk.

She has said that she doesn't want to marry me if she's just my female best friend that I sleep with. But I don't know how to evaluate what she's asking. There are a number of possibilities. Maybe I don't feel the requisite feelings and thus she wouldn't want to be married. Maybe I do have the feelings and I have no way to evaluate whether I do or not. Maybe I'm not ever going to feel some extra undetected thing X, ever, and so I should just go through the motions saying that I do, and our marriage prospects are entirely unchanged. Maybe this is just some signalling ritual we have to go through.

We both are concerned that I've not really had a relationship not with her, so there are no points of comparison for me to make.

In your list you didn't mention the topic of getting children. If you marry someone with the intention of spending the rest of your life together with them, I think you should be on the same page with regards to getting children before you marry.

What exactly do you think/hope will change between the current situation (which I assume involves you two living together) and the situation if you were to marry?

Comment author: Squark 23 April 2014 07:53:17PM 3 points [-]

I don't know what is the significance of marriage for you, except symbolic. IMO the truly critical point is having kids. You probably want to have stable income before that.

Regarding things you're "just supposed to know": same thing happens to me with my wife. Haven't stopped us from being together for 10 years and raising a 4 year old son. Different people see things differently and have different assumptions on what is "obvious". The important thing is being mutually patient and forgiving (I know it's easier said than done, but it's doable).

Regarding the "extra feeling". Don't really know what to tell you. It is difficult to compare emotional experiences of different people. When our relationship started, it was mad, passionate infatuation. Now it's something calmer but it is obvious to me we love each other.

I had few relationships apart from my wife and virtually no serious relationships. Never bothered me.

Comment author: ephion 23 April 2014 07:06:08PM 7 points [-]

Don't get married unless there is a compelling reason to do so. There's a base rate of 40-50% for divorce, and at least some proportion of existing marriages are unhealthy and unhappy. Divorce is one of the worst things that can happen to you, and many of the benefits of marriage to happiness are because happier people are more likely to get married in the first place.

Comment author: shminux 23 April 2014 09:30:46PM *  4 points [-]

She has said that she doesn't want to marry me if she's just my female best friend that I sleep with.

What are her feelings about you? Are you "just" her "male best friend that she sleeps with"? Your post comes across as rather asymmetric.

We both are concerned that I've not really had a relationship not with her, so there are no points of comparison for me to make.

Aren't you "both concerned" that she had too many relationships and so may decide that you are not for her precisely because she has these "points of comparison"? I suspect that she is the dominant partner in this relationship, possibly because she is more mentally mature, and this is often a warning flag.

She sometimes gets mad at me for things I'm "just supposed to know" to do, not do, say, or not say. I'm not sure if she's right and I'm a jerk.

Do you get mad at her for things she is just supposed to know to do, say or not say?

Anyway. DO NOT GET MARRIED YET until you figure out how to be an equal in this relationship (and if you think that you are, then you are fooling yourself).

Married guys make more on average, but the arrow of causality could point in either direction or come from something else.

And married women make less, so even assuming the arrow of causality is entirely from marital status to income it's not clear to me what would happen to your combined income.

Comment author: 9eB1 27 April 2014 07:38:35PM 2 points [-]

Even if your combined income decreases, your combined consumption probably increases, because many goods are non-rivalrous in a marriage situation. See here for a discussion.

I was feeling lethargic and unmotivated today, but as a way of not-doing-anything, I got myself to at least read a paper on the computational architecture of the brain and summarize the beginning of it. Might be interest to people, also briefly touches upon meditation.

Whatever next? Predictive brains, situated agents, and the future of cognitive science (Andy Clark 2013, Behavioral and Brain Sciences) is an interesting paper on the computational architecture of the brain. It’s arguing that a large part of the brain is made up of hierarchical systems, where each system uses an internal model of the lower system in an attempt to predict the next outputs of the lower system. Whenever a higher system mispredicts a lower system’s next output, it will adjust itself in an attempt to make better predictions in the future.

EDIT: Just realized, this model explains tulpas. Also has connections to perceptual control theory, confirmation bias and people's general tendency to see what they expect to see, embodied cognition, the extent to which the environment affects our thought... whoa.

I have trouble with the statement "In the end, we're all insignificant." I mean I get the sentiment, which is of awe and aims to reduce pettiness. I can get behind that. But I have trouble if someone uses it in an argument, such as: "Why bother doing X; we're all insignificant anyway."

Because, if you look closely, "significance" is not simply a property of objects. It is, at the very least, a function of objects, agents and scales. For example you can say that we're all insignificant on the cosmic scale; but we're also all insignificant on the microscopic scale. We're also insignificant for some trees in the middle of the rainforest or an alien in another galaxy. We're almost completely insignificant to some random person in the past, present or future, but much more significant to the people around us.

To put differently, given two actions A & B with expected utilities U & V, you should choose A over B iff U > V. Only the relative ordering of U & V is meaningful, not the absolute difference (the utility function can be scaled arbitrarily anyway).

I've been reading about maximizers and satisficers, and I'm interested to see where LessWrong people fall on the scale. I predict it'll be signficantly on the maximizer side of things.

A maximizer is someone who always tries to make the best choice possible, and as a result often takes a long time to make choices and feels regret for the choice they do make ('could I have made a better one?'). However, their choices tend to be judged as better, eg. maximizers tend to get jobs with higher incomes and better working conditions, but to be less happy with them anyway. A satisficer is someone who tries to make a 'good enough' choice - they tend to make choices faster and be happier with them, despite the choices being judged (generally) as worse than those of maximizers.

If not rationality, then what?

LW presents epistemic and instrumental rationality as practical advice for humans, based closely on the mathematical model of Bayesian probability. This advice can be summed up in two maxims: Obtain a better model of the world by updating on the evidence of things unpredicted by your current model. Succeed at your given goals by using your (constantly updating) model to predict which actions will maximize success.

Or, alternately: Having correct beliefs is useful for humans achieving goals in the world, because correct beliefs enable correct predictions, which enable goal-accomplishing actions. The way to have correct beliefs is to update your beliefs when their predictions fail.

Stating it this baldly gets me to wonder about alternatives. What if we deny each of these premises and see what we get? Other than Bayes' world, which other worlds might we be living in?


Suppose that making correct predictions does not enable goal-accomplishing actions. We might call this Cassandra's world, the world of tragedy — in which those people who know best what the future will bring, are most incapable of doing anything about it. In the world of heroic myth, it is not oracles but rather heroes and villains who create change in the world. Heroes and villains are people who possess great virtue or vice — strong-willed tendencies to face difficult challenges, or to do what would repulse others. Heroes and villains defy oracles, and come to their predicted triumphs or fates not through prediction, but in spite of it.

Suppose that the path to success is not to update your model of the world, so much as to update your model of your self and goals. The facts of the world are relatively close to our priors, but our goals are not known to us initially, and are in fact very difficult to discover. We might consider this to be Buddha's world, the world of contemplation — in which understanding the nature of the self is substantially more important to success than understanding the external world. When we make choose actions that cause bad effects, we aren't so much acting on faulty beliefs about the world, but pursuing goals that are illusory or empty of satisfaction.

There are other models as well, that could be extrapolated from denying other premises (explicit or implicit) of Bayes' world. Each of these models should relate prediction, action, and goals in different ways. We might imagine Lovecraft's world, Qoheleth's world, or Nietzsche's world.


Each of these models of the world — Bayes' world, Cassandra's world, Buddha's world, and the others — does predict different outcomes. If we start out thinking that we are in Bayes' world, what evidence might suggest that we are in Cassandra's or Buddha's world?


Edited lightly — In the first couple of paragraphs, I've clarified that I'm talking about epistemic and instrumental rationality as advice for humans, not about whether we live in a world where Bayesian math works. The latter seems obviously true.

That's an interesting post. Let me throw in some comments.

I am not sure about the Cassandra's world. Here's why:

  • Knowing X and being able to do something about X are quite different things. A death-row prisoner might be able to make the correct prediction that he will be hanged tomorrow, but that does not "enable goal-accomplishing actions" for him -- in the Bayes' world as well. Is the Cassandra's world defined by being powerless?

  • Heroes in myth defy predictions essentially by taking a wider view -- by getting out of the box (or by smashing the box altogether, or by altering the box, etc.). Almost all predictions are conditional and by messing with conditions you can affect predictions -- what will come to pass and what will not. That is not a low-level world property, that's just a function of how wide your framework is. Kobayashi Maru and all that.

As to the Buddha's world, it seems to be mostly about goals and values -- things on the subject of which the Bayes' world is notably silent.

Is the Cassandra's world defined by being powerless?

Powerlessness seems like a good way to conceptualize the Cassandra alternative. Perhaps power and well-being are largely random and the best-possible predictions only give you a marginal improvement over the baseline. Or else perhaps the real limit is willpower, and the ability to take decisive action based on prediction is innate and cannot be easily altered. Put in other terms, "the world is divided into players and NPCs and your beliefs are irrelevant to which of those categories you are in."

I don't particularly think either of these is likely but if you believed the world worked in either of those ways, it would follow that optimizing your beliefs was wasted effort for "Cassandra World" reasons.

Comment author: Lumifer 25 April 2014 05:20:09PM 2 points [-]

So then the Cassandra's world is essentially a predetermined world where fate rules and you can't change anything. None of your choices matter.

Comment author: fubarobfusco 26 April 2014 01:06:42AM 1 point [-]

Alternately, in such a world, it could be that improving your predictive capacity necessarily decreases your ability to achieve your goals.

Hence the classical example of Cassandra, who was given the power of foretelling the future, but with the curse that nobody would ever believe her. To paraphrase Aladdin's genie: "Phenomenal cosmic predictive capacity ... itty bitty evidential status."

Yes, a Zelazny or Smullyan character could find ways to subvert the curse, depending on just how literal-minded Apollo's "install prophecy" code was. If Cassandra took a lesson in lying from Epimenides, she mightn't have had any problems.

Comment author: shminux 25 April 2014 06:12:28PM *  3 points [-]

I don't see these as alternatives, more like complements.

Suppose that making correct predictions does not enable goal-accomplishing actions. We might call this Cassandra's world

It's a memorable name, but it does not need to be called anything so dramatic, given that we live in this world already. For example, most of us make a likely correct prediction that if we procrastinate less then we will be better off, yet we still waste time and regret it later.

Suppose that the path to success is not to update your model of the world, so much as to update your model of your self and goals.

Why this AIXIsm? We are a part of the world, and the most important part of it for many people, so updating your model of self is very Bayesian. Lacking this self-update is what leads to a "Cassandra's world".

How strong is the evidence in favor of psychological treatment really?

I am not happy. I suffer from social anxiety. I procrastinate. And I have a host of another issues that are all linked, I am certain. I have actually sought out treatment with absolutely no effect. On the recommendation of my primary care physician I entered psychoanalytic counseling and was appalled by the theoretical basis and practical course of "treatment". After several months without even the hint of a success I aborted the treatment and looked for help somewhere else.

I then read David Burns' "Feeling Good", browsing through, taking notes and doing the exercises for a couple of days. It did not help, of course in hindsight I wasn't doing the treatment long enough to see any benefit. But the theoretical basis intrigued me. It just made so much more sense to be determined by one's beliefs than a fear of having one's balls chopped off, hating their parents and actively seeking out displeasure because that is what fits the narrative.

Based on the key phrase "CBT" I found "The now habit" and reading me actually helped to subdue my procrastination long enough to finish my bachelor's degree in a highly technical subject with grades in the highest quintile. Then I slipped back into a phase of relative social isolation, procrastionation and so on.

We see these phenomena consistently in people. We also see them consistently in animals being held in captivity not suited to their species' specific needs. I am less and less convinced that this block of anxiety, depression and procrastination is a disease but a reaction to an environment in the broadest sense inherently unsuitable to humans.

The proper and accepted procedure for me would be to try counseling again, this time with a cognitive behavioral approach. But I am unwilling to commit that much time for uncertain results, especially now that I want to travel or do a year abroad or just run away from it all. (Suicide is not an option) What lowers my odds of success even more is that I never feel understood by people put in place to understand in various venues. So how could such a treatment help?

I am open to bibliotherapy. I don't think I am open to traditional or even medical therapy.

I have suffered from social anxiety continuously and depression off and on since childhood. I've sought treatment that included talk therapy and medication. Currently I am doing EMDR therapy which may or may not end up being helpful, but I don't expect it to work miracles. Everyone in my immediate family has had similar issues throughout their lives. I feel your pain. Despite not being perfect and being in therapy, I feel like my life is going pretty well. Here is what has worked for me:

Acceptance: Not everyone can be or should be the life of the party. Being quiet or reserved or shy is a perfectly acceptable way to live your life. You can still work on becoming comfortable in more social situations but you are fine right now. There are plenty of people who will like you just as you are, even if you social skills are far from perfect. Harsh self-judgement can make anxiety worse and lead to procrastination and depression. What I try to do as best I can is to just do whatever I feel like in the moment, and just let the world correct me. I try not to develop too many theories about how the world will react to me since I know from experience that those theories will be biased and pessimistic.

Decide what you want from the world: I guess this is somewhat generic life advice, but it has really worked for me. I decided fairly early on what I wanted to get from the social world. I wanted 3 things. - marriage - children - a good career

Deciding those things, I plugged away at getting them. I was completely incompetent at talking to women but with some help from e-harmony I found one who I was able to be comfortable with and who liked me. We got married 6.5 years ago and we have a 2 year old daughter and another child on the way. Professionally, I found a career that involves a minimum of politicking and no customer interaction. And yet it is both intellectually satisfying and highly remunerative. Even though neither my home life nor my professional life are perfect, achieving my basic life goals has given me a deep feeling of confidence and satisfaction that I can use to counter feelings of anxiety and depression as they come.

Each step I took along the path towards my goals gave me more confidence to move forward, but that confidence wasn't necessarily automatic. I have to periodically brag to myself about myself because otherwise I will naturally focus on my failures and weaknesses and start to feel like a loser. You should be very proud of your accomplishments in college. Most people could not do what you have done. Remind yourself of that. Feel good about yourself.

I think the evidence shows that it works for some people, doesn't work for other people, and the spectrum of outcomes stretches all the way from "miraculously fixed everything" to "made everything worse" :-/

Oh, and "some people" and "other people" refers not just to the person being treated, but to a patient/psychotherapist pair. It is fairly common for people to have no success with a chain of therapists until they find "the one" who clicks and can effectively help with whatever the problem is.

What does it mean for a dog to be procrastinating?

Procrastination usually involves human wanting to do things that are not natural.

I used to believe that procrastination was something very unique to me but today I believe that nearly everyone struggles with it to some extend. Even someone like Tim Ferriss who advises a dozen startups and writes a book at the same time still deals with it. People who are productive simply have found strategies to still be productive despite being imperfect humans.

Disagree. Frequent discussion of one's anxieties can be a heavy burden on a friendship, and it's vulnerable to cascading failures. If I have four friends and spread my worries evenly between them, and one finds this exhausting and decides to spend less time with me, then I have three friends I can talk to, each of whom will suddenly find me even more stressful to be around.

Sorry if this has topic has been beaten to death already here. I was wondering if anyone here has seen this paper and has an opinion on it.

The abstract: "This paper argues that at least one of the following propositions is true: (1) the human species is very likely to go extinct before reaching a “posthuman” stage; (2) any posthuman civilization is extremely unlikely to run a significant number of simulations of their evolutionary history (or variations thereof); (3) we are almost certainly living in a computer simulation. It follows that the belief that there is a significant chance that we will one day become posthumans who run ancestor-simulations is false, unless we are currently living in a simulation. A number of other consequences of this result are also discussed."

Quite simple, really, but I found it extremely interesting.

Both in the sense of giving up on working toward getting into App Academy specifically [because I doubt I think fast enough / have a good enough memory to pass the challenges -- the first four problems in their second problem-set took me over an hour, and I had to look a few things up despite having gone through the entire Codecademy Ruby course] and in the sense of giving up on programming as an at-least-short-term job plan?

Not sure how much of this is lack of practice (maybe implementation / avoiding stupid errors would get better with practice, but designing the algorithms takes me a while, and I'm not new to programming at all), how much is overconfidence / unrealistically high expectations wrt skill (but they say the code challenges are supposed to take 45 minutes each) and how much is that I really don't have the talent to get into that particular program, or to not fail miserably at the job, or to develop the skills to be able to even get a programming job...

Hey, I have good news for you. I just tried those practice problems and timed myself to see if I could give you something to compare to (and for fun). I completed the first four in about an hour and 10 minutes (though I am a bit out of practice). Those practice problems are not trivial; they take some thought. I didn't have to use any outside resources, but I did have to test quite a few things out in the terminal as I was coding it.

For background: I am self taught, but I've been programming for almost 2 years. I have done freelance rails programming. I have built multiple rails apps from the ground up by myself. One of these is still in use by multimillion dollar company as a part of their client onboarding program. I've been offered a job as a rails developer, though I didn't end up taking it as I had a higher paying offer on the business end of things.

So I say don't worry if you have a bit of trouble with it. If you felt like you were looking things up all the time, then you just need some more practice. For the algorithm design part (especially the mathy ones), look into Project Euler. It's a great list of problems to get practice and you can use whatever language you want to find the answer, so use Ruby. Practice taking the problems apart into pieces, using helper functions, and writing the pseudocode before you actually code anything. That will make this style of thinking feel more natural.

Feel free to PM me if you want to talk more.

Use the try harder Luke.

What do you mean by "not new to programming at all"? How many hours programming have you done? How many projects have you completed? Because unless you've had a job as a programmer before or you did CS as a college degree your previous experience will be utterly swamped by App Academy. If you feel insecure about algorithms specifically practice them specifically. If you want more practice with Ruby maybe do Hartl's book. The Codecademy Ruby course is not the end of the world. If programming appeals to you prepare, apply and let App academy do the judging.

Edit: Remember, many people who have had jobs as programmers can't do FizzBuzz if asked to in an interview. Retain hope.

I'm an Orthodox Jew (Modern Orthodox). Since Mr. Yudkowsky's work is - obviously - apikorsus of the highest level, I read it l'havin ul'horos, mostly, but enjoy the thinking in it anyway.

Comment author: gjm 25 April 2014 09:00:30AM *  8 points [-]

In case anyone else is curious, it appears that:

"apikorsus" has a range of meanings including "heretic", "damned person", "unbeliever"; the term may or may not be derived from the name of Epicurus.

[EDITED to add: As pointed out by kind respondents below, I was sloppy and mixed up "apikores" (which has the meanings above) and "apikorsus" (which means something more like "the sort of thing an apikores says"). My apologies.]

"l'havin ul'horos" means "to understand and to teach", as opposed to "to agree" or "to practice" or whatever. In the Bible, when the Israelites invade Canaan they are told not to learn to do as the natives do, and there's some famous commentary that says "but you are allowed to learn in order to understand and to teach".

[EDITED to add: I am not myself Jewish, nor do I know more than a handful of Hebrew words; if I have got the above wrong then I will be glad to learn.]

Comment author: iarwain1 25 April 2014 02:28:12PM 5 points [-]

More accurately: Apikores = heretic in modern parlance; apikorsus = heretical views.

As an aside, Maimonides is the medieval Jewish authority generally associated with the view that the term apikores is not derived from the name Epicurus. Maimonides was a world-class Aristotelian philosopher and quotes Epicurus several times in his works. Since the words apikores and Epicurus have identical spellings in medieval Hebrew, the fact that Maimonides proposes a different etymological theory begs for an explanation. Maimonides' theory is that the term is from the Aramaic "apkeirusa" (this is hard to translate, especially in the way Maimonides seems to be using it; I think it implies something like "people doing whatever they feel like instead of listening to authority figures"). I've long felt that this derives from the fact that the Talmud's discussion of the term doesn't have anything to do with dogma or heretical beliefs but rather with belittling authority figures. Maimonides himself, however, converts the term in his other works into the current usage of referring to heretical beliefs. Based on this, I strongly suspect that Maimonides thought that the original term does stem from Epicurus (who held precisely those beliefs that Maimonides identifies as heretical), but that the rabbis of the Talmud borrowed the term and used it as a sort of Aramaic-Greek pun to refer to belittling authority figures.

Also in case anybody else is curious, Modern Orthodox is as opposed mainly to Ultra-Orthodox (also known as "hareidi" or "frum"). Hassidim are their own sub-group of Ultra-Orthodox.

As an interesting intellectual challenge, try steelmanning some of the hareidi sociopolitical positions, such as their extreme opposition to the Israeli draft law. And it does need steelmanning - I personally know several very well-thought-out, very smart, very well-meaning, very knowledgeable rabbis who strongly agree with the hareidi positions.

As an interesting intellectual challenge, try steelmanning some of the hareidi sociopolitical positions, such as their extreme opposition to the Israeli draft law. And it does need steelmanning - I personally know several very well-thought-out, very smart, very well-meaning, very knowledgeable rabbis who strongly agree with the hareidi positions.

I think that actually if you accept a certain basic worldview, they have a rather strong case. I strongly disagree with that worldview, but that's a diffrent matter.

Let's lay it out:

Axiom 1: Everything happens acording to God's will.

Axiom 2: If we behave righeously, God's will will be favourable.

Example: Again and again in the past, this has happened. "בכל דור ודור עומדים עלינו לכלותינו והקדוש ברוך הוא מצילנו מידם" [Rough translation: "In each and every generation our foes have tried to destroy us, and each time the Holy One Blessed Be He saves us from them.]

Corollary 1: If we are righteous, we can expect this to carry on in the present and the future.

Axiom 3: The most righteous thing to be doing is to be studying the Holy Texts.

Lemma: We need to have as large a number of people as possible studing in yeshiva as their day-to-day occupation.

Proof of the lemma: Follows from Corollary 1 and Axiom 3.

Preposition: "Much as it pains us, we acknowledge that not everyone has it in them to spend all day studying Torah. We don't want to force people who don't want to study in yeshiva to do so (much as it aches the very bottoms of our souls), but at least you can let those who want to do so get on with it, and not waste their time on your secular 'army' nonsense, which has nothing to do with our defense, as our only true defense is God."

Proof of the preposition: The lemma says that we need lots of yeshiva bochers, so let's provide them! If you don't have the proper כונה we cannot effectivly force you to study Torah (even if the hareidim had the political power), but at least we can take the masses of willing hareidi young men and allow the to do their job for the defense of our people, in order to protect what fragment of spiritual defense we still have.

Corollary 2: The state of Israel shouldn't draft the yeshiva bochurs. Doing so removes our only true line of defense, and so is taramount to the genocide of the Jewish people.

If you accept the three axioms, it leads invariably to the Preposition, and so to Corollary 2.

Q.E.D.

That would work... but the Chareidim don't actually believe in their defenses (they flee places getting bombed and leave the soldiers to defend people's lives), nor are these defenses backed up in any way by halacha (they're misinterpreted that one text they use as a source). Also, they don't allow anyone in their community to go into the army. Ever. And they don't let non-Chareidim join them in their learning for defense, either.

I suspect noonehomer's correct in part and that the chareidim don't actually believe everything that Username says.

Also, I don't think it's true they don't let anyone go to the army (or at least it didn't use to be), just that it's discouraged.

If anyone's interested in my own thoughts, I posted them in a comment here. Just look for the comment by iarwain. Sorry, you may need to understand some hebrew terms to understand it. But then again, you'll need to understand hebrew terms to read Username's comment as well.

Almost certainly I can. But right now I'm in high school, so I don't know that many people who qualify.

Um... assur means you can't do it. It's not less severe than "forbidden", I don't think. It literally means "bound". It's important to note that it doesn't mean something's morally wrong, but in this case, independent of the prohibition (non-literal translation of the noun form, issur) the act of reading foreign philosophy without knowledge of the corresponding arguments in one's own can cause stupid questions, not smart ones, and is considered to be wrong, not just forbidden (in my father's circles, anyhow).

I commend you for your self-control in not telling other people about these issues. I'd also add that for many people who aren't the intellectual type, you'd be doing them a major disservice by exposing them to arguments that can easily cause them massive psychological stress issues. As I know from personal experience with people who that happened to.

It might be worth thinking about switching to a different high school where there are more intellectual-type people around. Also, if you go to Yeshiva University for college you'll find plenty of smart people, both staff and students, who are quite educated in foreign philosophies.

Humans are diverse.

I mean this not only in the sense of them coming all kinds of shapes, colours and sizes, having different world views and upbringings attached to them, but also in the sense of them having different psychological, neurological and cultural makeup. It does not sound like something that needs to explicitly said but apparently it needs to be said.

Of course first voices have realised that the usual population for studies is WEIRD but the problem goes deeper and further. Even if the conscientious scientist uses larger populations, more representative for the problem at hand, the conclusions drawn tend to ignore human diversity.

One of the culprits is the concept of "average" or at least a misuse of it. The average person has an ovary and a testicle. Completely meaningless to say, yet we are comfortable in hearing statements like "going to college raises your expected income by 70%" (number made up) and off to college we go. Statements like these suppress a great deal of relevant information, namely the underlying, inherent diversity in the population. Going to college may increase lifetime earnings, but the size of this effect might be highly dependent on some other factor like inherent cognitive ability and choice of major.

Now that is obvious, you might say, but virtually all research shows that this is not the case. It was surprising to see that the camel has two humps, that is, one part of the population seems to be incapable of learning programming, while the other is. And this can be determined by the answer to a single question. Research on exercise and diet is massively convoluted with questions about endurance/strength and carbs/fats. May this be because of ignoring underlying biological factors?

People are touting the coming age of personalised medicine as they see massively diminishing returns on generic medicine. Ever more diseases are hypothesised to have very specific causes for each person necessitating ever more specialised treatment. The effects of psychedelic substances are found to be dependant on the exact psychological makeup, e.g. cannabis causing psychosis only in individuals already at risk for such episodes.

There is no exact point to this rant. Just the observation that ever more statements are similar to saying "having unprotected sex with your partner has a high probability of leading to pregnancy" to homosexual man.

There are three separate issues:

(a) The concept of averaging. There is nothing wrong with averages. People here like maximizing expected utility, which is an average. "Effects" are typically expressed as averages, but we can also look at distribution shapes, for instance. However, it's important not to average garbage.

(b) The fact that population effects and subpopulation effects can differ. This is true, and not surprising. If we are careful about what effects we are talking about, Simpson's paradox stops being a paradox.

(c) The fact that we should worry about confounders. Full agreement here! Confounders are a problem.


I think one big problem is just the lack of basic awareness of causal issues on the part of the general population (bad), scientific journalists (worse!), and sometimes even folks who do data analysis (extremely super double-plus awful!). Thus much garbage advice gets generated, and much of this garbage advice gets followed, or becomes conventional wisdom somehow.

Comment author: Lumifer 21 April 2014 05:37:18PM 4 points [-]

There is nothing wrong with averages.

That depends. Mostly they are used as single-point summaries of distributions and in this role they can be fine but can also be misleading or downright ridiculous. The problem is that unless you have some idea of the distribution shape, you don't know whether the mean you're looking at is fine or ridiculous. And, of course, the mean is expressly NOT a robust measure.

It was surprising to see that the camel has two humps, that is, one part of the population seems to be incapable of learning programming, while the other is.

The study you're probably thinking of failed to replicate with a larger sample size. While success at learning to code can be predicted somewhat, the discrepancies are not that strong.

http://www.eis.mdx.ac.uk/research/PhDArea/saeed/

The researcher didn't distinguish the conjectured cause (bimodal differences in students' ability to form models of computation) from other possible causes. (Just to name one: some students are more confident; confident students respond more consistently rather than hedging their answers; and teachers of computing tend to reward confidence).

And the researcher's advisor later described his enthusiasm for the study as "prescription-drug induced over-hyping" of the results ...

Clearly further research is needed. It should probably not assume that programmers are magic special people, no matter how appealing that notion is to many programmers.

The failure to replicate was of their test, not of the initial observation.

Hi, CFAR alumni here. Is there something like a prediction market run somewhere in discussion?

Going mostly off of Gwern's recommendation, it seems like PredictionBook is the go-to place to make and calibrate predictions, but it lacks the "flavour" that the one at CFAR did. CFAR (in 2012, at least) had a market where your scoring was based on how much you updated the previous bet towards the truth. I really enjoyed the interactional nature of it.

What would it take to get such a thread going online? I believe one of the reasons it worked so well at minicamp was because we were all in the same area for the same period of time, so it was simple to restrict bets to relevant things we could all verify. Even if most of the posts wind up being relevant only to the local meetups, it would be nice to have them up in the same place for unofficial competition. Is that something you would use?

On the standard anti-akrasia topics, the narrative is that if you have anxiety,depression, xyz that you should treat that first, but there seems to be a lack of quantity of members that have this. Going to other forums to talk about stuff like which medication is "better" is filled with a lot of bad epistemology, conclusions, people faking their disorder, and much more.

A monk came to Master Banzen and asked, "What can be said of universal moral law?"

Master Banzen replied, "Among the Tyvari of Arlos, all know that borlitude is highly frumful. For a Human of Earth, is quambling borl forbidden, permissible, laudable or obligatory?"

The monk replied, "Mu."

Master Banzen continued, "Among the Humans of Earth, all know that friendship is highly good. For a Tyvar of Arlos, is making friends forbidden, permissible, laudable or obligatory?"

The monk replied, "Mu," and asked no more.

Sounds to me like the master's jumping to more conclusions than the student is, here.

Parochial because he mistook a local property of mindspace for a global one; unimaginative because he never thought of frumfulness when considering what things a mind might value. "Good" is no more to a Tyvar than "frumful" to Clippy or "clipful" to a human.

I'd say that even more important than giving explanation is not downvoting merely because you disagree. The signal transmitted by downvoting is "I don't want the hear this" or in simpler language "shut up". This should be reserved to fight content which is offensive, spam, trolling, rampant crackpottery, blatant off-topic etc. Mistakes made in good faith don't deserve a downvote. I'd say it is an extension of the "Bad argument gets counterargument. Does not get bullet. Never. Never ever never for ever." rule. The alternative is death spirals, blue-green politics and plainly ruining the community experience for everyone.

I personally made a rule of upvoting any content with net negative score which doesn't deserve a downvote, even if I disagree, especially when it's a comment of a person I'm currently arguing against. I want arguments that are discussions in which both sides are trying to arrive at the truth, not fights or two-people-showing-off-how-smart-they-are (is there a name for it?).

Downvotes are not the way to achieve it. The way to achieve it is by positive personal example and upvoting content which is exemplary. Why are downvotes bad? Because:

  • We want to allow "mediocre" people (some of which have an unrealized potential to be excellent) that want to learn from excellent people (I hope you agree). Such people can make innocent mistakes. There's no reason to downvote them as long as they're willing to listen and aren't arrogant in their ignorance. Downvoting will only drive them away.

  • Even smart people occasionally say foolish things. Downvoting sends such a strong negative signal that it discourages even people that get much more upvotes than downvotes. By "discourages" I don't mean "discourages from saying foolish things", I mean discourages from participating in the community in general.

  • Most content is not voted upon by most of the community, therefore statistical variance is large. Again, since the discouragement of downvotes is not cancelled out by the encouragement of upvotes, you get much more discouragement than you want.

  • Downvotes transform arguments into sort of arena fights where the people in the crowd are throwing spoiled vegetables on the players they don't like. The emotional aura this creates is very bad for rationality. It's excellent for blue-green politics (downvote THEM!) and death spirals.

Punishment is different enough from deciding who to talk with.

If you don't want to talk to someone, don't upvote her and don't reply to her. The psychological impact of downvoting is equivalent to punishment.

See also Yvain on safe spaces.

This is completely different. "Safe spaces" are about banning content which might offend someone's sensibilities. My suggestion is about "banning" less content.

Why are downvotes bad? Because:

I agree with enough of this. I know there are immediate downsides and hypothetical dangers. But the upsides seem indispensable. The argument needs to consider the balance of the two.

If you don't want to talk to someone, don't upvote her and don't reply to her.

They remain in the fabric of the forum, making it less fun to read. Not upvoting doesn't address this issue.

"Safe spaces" are about banning content which might offend someone's sensibilities. My suggestion is about "banning" less content.

Things that are not fun (for certain sense of "fun") offend my sensibilities (for certain sense of "offend"). My suggestion is to discourage them by downvoting. (This is the intended analogy, which is strong enough to carry over a lot of Yvain's discussion, even if the concept "safe spaces" doesn't apply in detail, although I think it does to a greater extent than I think you think it does.)

I have no problem with that, my problem is with the opposite - people learning from mediocre (or worse) folk, because they don't realize that their content is flawed (which downvotes signal).

To some extend yes, but we don't want eternal September either. There concern about the average IQ that reported in the LW census dropping over time.

Downvoting sends such a strong negative signal that it discourages even people that get much more upvotes than downvotes.

If we would have less downvotes in general then every single downvote would create a much stronger negative signal than it does at the moment.

What do you mean by "fighting mediocrity"? Should I interpret it literally as "I don't like mediocre people"? Or as "I want to reward excellence"? If it is the latter you are aiming it, use upvotes, not downvotes (for ideal rational agents the two might be symmetric, but for people they aren't: the emotional signal from getting a downvoting is very different from the emotional signal of not getting an upvote).

Exactly, and this is a reason why downvoting is important (and shouldn't be systematically countered): it allows scaring people away (who are not of our tribe). A forum culture that would merely abstain from upvoting is worse at scaring people away than one that actively downvotes.

Upvoted for making an interesting point.

However: I was not appealing to Eliezer's authority. I was just making a parallel with a similar (but more extreme) phenomenon.

Regarding well-kept gardens. Let me put things in perspective. If you see a comment along the lines of "jesus is our lord" or "rationality is wrong because the world is irrational" or "a machine cannot be intelligent because it has no soul", by all means downvote. However, if you see two people debating e.g. whether there will be an AI foom or whether consequentialism is better than deontology or whether AGI will come before WBE, don't downvote someone just because you disagree. Downvote when the argument is so moronic that you're confident you don't want this person in our community.

People change. People change even faster when you give them feedback. I downvote things I don't want to see from people I like and respect the same way I would frown at a friend if they did something I didn't want them to do.

So instead of 'I'm confident I don't want you in our community,' I view a downvote more as 'shape up or ship out.'

Nope. Sometimes otherwise-okay people make moronic arguments because they're mind-killed, they're tired, etc.

THE WHOLE POINT OF DOWNVOTES IS TO HAVE LESS BAD STUFF AND MORE GOOD STUFF. This applies not just to making people leave but making people who stay post tbings of higher quality.

If you don't downvote "otherwise-okay" people when they say dumb shit, how are they supposed to learn. Downvote the comment, not the person .

The signal transmitted by downvoting is "I don't want the hear this" or in simpler language "shut up". This should be reserved to fight content which is offensive, spam, trolling, rampant crackpottery, blatant off-topic etc.

I think you're drawing a false equivalence here. While a downvote does carry the meaning of "I don't want to hear this", most of the meaning of "shut up" is connotation, not denotation, and those connotations don't necessarily carry over.

Mere disagreement generally isn't enough to justify a downvote, no. But we want to see well-reasoned disagreement: it signifies a chance to teach or to learn, even if it's unpleasant in the moment. On the other hand, there are plenty of things short of Time Cube or cat memes that one might legitimately not want to see here, even if posted in good faith; restricting the option to those most extreme cases robs it of most of its power to improve discussion.

I personally made a rule of upvoting any content with net negative score which doesn't deserve a downvote, even if I disagree

I donwvoted you, because you seem to use upvotes in a way that diminishes the value of the karma system in my eyes - an undeserved downvote is as bad as an undeserved upvote.

I've seen a lot of low quality posts getting some karma, and coming back to positive scores without a good reason - and now I know the behaviour that is partially responsible.

(and the above comes from someone with a mass downvoter after him, who gets a downvote on every single comment he makes)

This is a common question from the new participants. First, there is no policy on downvoting. There can't be, because there is no enforcement mechanism. There are, however, recommendations, like "downvote something you would like to see less of", which is often mixed up with "downvote everything I disagree with", or worse, with "downvote every comment by a user I dislike, regardless of content, to force them post less". At least one prominent regular has been accused of this last one. Second, commenting on why you downvote tends to result in the comment being downvoted, which discourages such comments very effectively.

it's frustrating and a poor feedback mechanism.

Yes, but only in the beginning. Once you have a few hundred karma, a downvote is just an indication that someone disliked your post, nothing more. And if all your comments are universally liked, you must be doing something wrong.

Comment author: Eugine_Nier 27 April 2014 05:16:37AM 1 point [-]

What's the current policy on bare downvoting, as in downvoting a comment/post without giving at least a short explanation for why one did so?

Well, Eliezer's policy tends towards "replying to downvote-worthy comments tends to start flame wars and is thus discouraged".

Comment author: [deleted] 27 April 2014 05:19:59AM 1 point [-]

Right, but then we invented "Tapping out" so that wouldn't become an issue.

Comment author: Eugine_Nier 27 April 2014 05:23:06AM 1 point [-]

"Tapping out" can be interpreted as conceding and is thus low status.

If you're that worried, link to the wikipage which defines away that connotation, like "I'm tapping out.".

Call it something else then, or be more direct and paraphrase the wikipage, or take it into PMs, whatever you fancy. The point is that you shouldn't feel guilty replying to a comment just because it was downvoted.

Fairly off-topic question, but I imagine there'll be suitable people to answer it on LW. Any recommendations for cheap and cheerful VPS hosting? Just somewhere to park a minimum CentOS install. It's for miscellaneous low-priority personal projects that I might abandon shortly after starting, so I'm hesitant to pay top dollar for a quality product that I might end up not using. On the other hand, I want to make sure I get what little I'm paying for.

I would like to learn drawing.

I would like to be able to have fun expressing myself via art. How long does it takes to learn to draw from zero to good enough not to be embarrassed of oneself?

What techniques are useful? Is there any sense in e.g. Drawing on the Right Side of the Brain?

Comment author: raisin 21 April 2014 02:07:48PM *  4 points [-]

Drawing from the real life is especially useful for someone who is learning to draw. It teaches you that drawing is not simply about holding a pen and drawing the correct lines, but it's also about seeing and thinking correctly. We tend to think in terms of shapes, outlines and symbols, but such things don't represent the reality very well. You should be thinking in terms of form and contour.

Here's a good video about it.

I think this post is a good start:

So forget drawing humans for a while and start painting simple primitives. Cylinders, spheres, spheres with a section sliced off, cylinders which end with a sphere, stuff like that. Don't even color them, just work in grayscale and try to get the lighting right. Use real cylinders or photos of cylinders as reference. Buy some clay, sculpt some simple primitives and draw those. Do it over and over again while looking at what you see instead of drawing what you think you see. The more you do it, the faster you'll get better.

And when you feel comfortable with basic forms, you can start combining them into more elaborate forms. When you use reference, try to see the basic shapes of which your reference form consists of. A human head is like a sphere, with both sides sliced off, attached to a cylinder. Of course, there's a LOT more to human heads. Keep it simple until you're comfortable with drawing tens, if not hundreds of primitive contours together, because that's what heads consist of.

If you're drawing from reference (which you should be doing), try flipping the reference image upside down before drawing a single stroke. This can trick your brain into actually looking at form instead of sticking with the symbolic shapes which are deeply ingrained with how you look at the world. Crop the reference image to a tiny area, then try to replicate it as closely as possible. Then do it again even better. And again and again etc.

So draw a lot, draw from the real life and draw from reference and begin to think in 3D.

I think Drawing on the Right Side of the Brain is probably pretty effective because one of its main point is the above - that you should just draw what you see and not think in terms of symbols when you draw. The underlying idea about the brain hemispheres is pseudoscience, but that doesn't mean it can't still teach useful lessons.

Comment author: [deleted] 23 April 2014 05:55:23AM 1 point [-]

Drawing on the Right Side is great for this reason. The hemisphere stuff is quite tangential to the book's utility.

If you want to see examples of "visual symbols", look at the drawings of children. In particular, look at drawings of the human face. The prototypical symbols for something like an eye, just don't look that much like a human eye. This sounds obvious, but it's very hard to just draw what you see, and not draw what you "think you ought" to see.

For example, imagine a face lit from one side. Visually, the illuminated side of the face will show the "expected" details: You'll see the folds in both lids of the eye, and the fine curves of the face and ear. But the dark side of the face will look nothing like this. You'll only see broad dark areas and broad light areas. However, most people who'd identify as "bad at drawing", will draw the same details on both sides of the face, and will be genuinely unaware that this isn't what they really "see".

This isn't to say that artists don't make use of visual symbols, etc, but skill is the ability to take both approaches.

I'd actually advance this as a example of the fundamental analysis of one type of "talent". The "good at drawing" people grokked the connection between seeing and drawing, and the "bad at drawing" people didn't.

I've wondered for some time if something similar isn't present in musical talent, where the basic "mindset" has to do with some connection of sound to expression, rather than a connection between sound and physical ritual.
