I simply say to them "Er, human technology has progressed to the point where I can have, say, a sweet breakfast without consuming any sugar, and I'm going to do so. Cheating has nothing to do with it."

It's true that artificial sweeteners mean you can get a sweet taste without consuming calories. Beware the conclusion that they therefore don't cause you to gain weight or have other negative health effects though. There's plenty of evidence to the contrary.

I agree that eating healthily doesn't mean having to deprive yourself of all delicious fo... (read more)

I'm not sure you need uncertainty to discount at all - in finance exponential discounting comes from interest rates which are predicated on an assumption of somewhat stable economic growth rather than deriving from uncertainty.

As you point out, hyperbolic discounting can come from combining exponential discounting with an uncertain hazard rate. It seems many of the studies on hyperbolic discounting assume they are measuring a utility function directly when they may in fact be measuring the combination of a utility function with reasonable assumptions abou...

Do any of the studies on hyperbolic discounting attempt to show that it is not just a consequence of combining uncertainty with something like a standard exponential discounting function? That's always seemed the most plausible explanation of hyperbolic discounting to me and it meshes with what seems to be going on when I introspect on these kinds of choices.

Most of the discussions of hyperbolic discounting I see don't even consider how increasing uncertainty for more distant rewards should factor into preferences. Ignoring uncertainty seems like it would be a sub-optimal strategy for agents making decisions in the real world.

There's room for debate whether we saw a true currency crisis in the Euro but 'this prediction has failed utterly' is overstating it. We saw unusually dramatic short term moves in the Euro in May and there was widespread talk about the future of the Euro being uncertain. Questions about the long term viability of the Euro continue to be raised.

I'd argue that charting any of the major currencies against gold indicates an ongoing loss of confidence in all of them - from this perspective the dollar and the euro have both declined in absolute value over the y... (read more)

According to this article a sense of vibration and rapid acceleration of the body are fairly commonly reported (I don't recall experiencing these symptoms myself). That article and the Wikipedia entry both mention some of the mythology and folklore surrounding the experience from different cultures.

Paleo diets generally consider corn a grain so you might want to avoid that. Some paleo variants (like the one I'm currently following) are ok with cheese and yogurt in moderation (and butter).

I would guess this is not true in general since many things do not want to be eaten and so evolve various defense mechanisms. In turn the organisms that eat them may develop counter-measures that enable them to safely digest their meal despite the defense mechanisms but this will depend on the complex evolutionary history of both organisms. Ruminants are adapted to a quite different diet than humans for example.

I wonder why an apple should be healthy. Wouldn't any animal be satisfied with a fruit that just had calories? Enough, in any case, to come back for more and scatter the seeds? Why should an apple -- or anything 'natural' -- be so especially healthy for humans?

You're missing the other side of the story. Humans evolved to obtain their nutritional needs from those foods that were available in the EEA and this effect is probably more significant than the selection pressure in the other direction (on fruits to be nutritionally beneficial to animals that eat them). Humans are adapted to a diet that includes things that were available to them during the long pre-agricultural evolutionary period.

You're probably right but ironically I've ignored much of the standard advice on employment and it's worked out just fine for me so this example doesn't resonate very well for me. I've never worn a suit to a job interview for example.

I assumed he was saying something like "the majority of women prefer a man more 'masculine' than the median man". By analogy, if it is true that "the majority of men prefer a woman who is slimmer than the median woman" it should be obvious that being overweight will make it harder for a woman to find a match even if there are men who prefer less slim women. Saying "men prefer slim women" is a slightly sloppy generalization but not an unreasonable one in this example.

This confuses me, because it seems to imply that men need to believe that a simple personality heuristic can be applied to all or almost all women. Why is it an unacceptable answer that some women like one thing, and some like another?

The prevalence of different personality types in the population is very relevant here and you seem to be glossing over it. If the number of women attracted to your personality type is relatively low (and especially if it is low relative to the number of other men similar to you) it will still be an obstacle you need to ove...

I think there's a bit more to it than just women overlooking a lack of values because of other attractive factors like confidence. There's some evidence that men with the 'dark triad' personality traits are more successful with women.

I wonder how many potential matches know enough maths to realize why he used powers of two?

A dealbreaker is something that on its own automatically rules someone out. A factor is something that swings the overall impression positively or negatively but is not on its own a deciding factor independent of other factors.

I agree the choices aren't ideal but I think "likes children", "dislikes children" and "doesn't want children" all match a search for "Doesn't have children" whereas leaving the question blank or answering that you have children means you won't show up in a search that specifies "Doesn't have children". It's a bit confusing and not a very logical setup but I think that's how it works.

I've left the "children" field blank, for example, because I don't want them now but might some day, so neither "wants" nor "doesn't want" is correct.

I think this might be a mistake. I usually specify "Doesn't have children" when I do a match search and I'd guess this is fairly common. If you leave this question blank I believe you won't show up for people who are filtering on that search criteria.

Historically, global population increase has correlated pretty well with increases in measures of overall health, wealth and quality of life. What empirical evidence do you derive your theory that zero or negative population growth would be better for these measures from?

I just don't see any practical examples of people successfully betting by doing calculations with probability numbers derived from their intuitive feelings of confidence that would go beyond what a mere verbal expression of these feelings would convey. Can you think of any?

I'd speculate that bookies and professional sports bettors are doing something like this. By bookies here I mean primarily the kind of individuals who stand with a chalkboard at race tracks rather than the large companies. They probably use some semi-rigorous / scientific techniques t...

I expected the third to be higher than most less wrongers would estimate.

In reality, it is rational to bet only with people over whom you have superior relevant knowledge, or with someone who is suffering from an evident failure of common sense.

You still have to be able to translate your superior relevant knowledge into odds in order to set the terms of the bet however. Do you not believe that this is an ability that people have varying degrees of aptitude for?

Look at the stock market: it's pure gambling, unless you have insider knowledge or vastly higher expertise than the average investor.

Incidentally, do you mean GDP per capita would decrease relative to more interventionist economies or in absolute terms? Since there is an overall increasing trend, in both more and less libertarian economies that would be very surprising to me.

I wondered about this as well. It seems an extremely strong and unlikely claim if it is intended to mean an absolute decrease in GDP per capita.

Given your position on the meaninglessness of assigning a numerical probability value to a vague feeling of how likely something is, how would you decide whether you were being offered good odds if offered a bet? If you're not in the habit of accepting bets, how do you think someone who does this for a living (a bookie for example) should go about deciding on what odds to assign to a given bet?

The two things that seem to work for me most of the time: "will I feel proud / good about myself for doing this?" or, if that fails, "would person X (whose opinion of me is generally important to me) be impressed or disgusted with this behaviour if they knew about it?". Essentially, "is this behaviour consistent with the kind of person I wish myself and (particular) others to perceive me to be?".

I guess I'm playing the game right then :)

I'm curious, do you also think that a singleton is a desirable outcome? It's possible my thinking is biased because I view this outcome as a dystopia and so underestimate it's probability due to motivated cognition.

I don't know whether ant colonies exhibit principal-agent problems (though I'd expect that they do to some degree) but I know there is evidence of nepotism in queen rearing in bee colonies where individuals are not all genetically identical (evidence of workers favouring the most closely related larvae when selecting larvae to feed royal jelly to create a queen).

The fact that ants from different colonies commonly exhibit aggression towards each other indicates limits to scaling such high levels of group cohesion. Though supercolonies do appear to exist the... (read more)

Stable equilibrium here does not refer to a property of a mind. It refers to a state of the universe. I've elaborated on this view a little here before but I can't track the comment down at the moment.

Essentially my reasoning is that in order to dominate the physical universe an AI will need to deal with fundamental physical restrictions such as the speed of light. This means it will have spatially distributed sub-agents pursuing sub-goals intended to further its own goals. In some cases these sub-goals may involve conflict with other agents (this would be... (read more)

Two points that influence my thinking on that claim:

1. Gains from trade have the potential to be greater with greater difference in values between the two trading agents.
2. Destruction tends to be cheaper than creation. Intelligent agents that recognize this have an incentive to avoid violent conflict.

I agree with most of what you're saying (in that comment and this one) but I still think that the ability to give well calibrated probability estimates for a particular prediction is instrumentally useful and that it is fairly likely that this is an ability that can be improved with practice. I don't take this to imply anything about humans performing actual Bayesian calculations either implicitly or explicitly.

Are we only supposed to upvote this post if we think it is irrational?

• A Singleton AI is not a stable equilibrium and therefore it is highly unlikely that a Singleton AI will dominate our future light cone (90%).

• Superhuman intelligence will not give an AI an insurmountable advantage over collective humanity (75%).

• Intelligent entities with values radically different to humans will be much more likely to engage in trade and mutual compromise than to engage in violence and aggression directed at humans (60%).

Agree with 1 and 3, not sure exactly what you mean with 2.

It seems plausible to me that routinely assigning numerical probabilities to predictions/beliefs that can be tested and tracking these over time to see how accurate your probabilities are (calibration) can lead to a better ability to reliably translate vague feelings of certainty into numerical probabilities.

There are practical benefits to developing this ability. I would speculate that successful bookies and professional sports bettors are better at this than average for example and that this is an ability they have developed through practice and experie... (read more)

I've seen so many decent people turn into bastards or otherwise abdicate moral responsibility when they found themselves at the helm of a company, no matter how noble their initial intentions.

Do you think this is different from the general 'power corrupts' tendency? The same thing seems to happen to politicians for example.

Evernote recommendation seconded. It's a really neat tool (I particularly like the auto text recognition in images making them searchable).

I guess that until competitive government becomes really feasible in a mass scale, this thought is very theoritical.

One of the things I particularly like about the idea of competitive government is it gives you something practical to do now as an individual. Look around the world and consciously pick a country to live in based on the value offered by its government. Surprisingly few people do this but the few that do have been enough to give us the likes of Hong Kong, Singapore, Switzerland, Luxembourg, etc.

I found the discussion between Moldbug and Robin Hanson interesting because whilst Robin Hanson has lots of interesting ideas he does not write terribly well. He communicates his idea clearly but there is no style to his writing. Contrast Moldbug (or Eliezer) and see the impact of interesting ideas expressed with eloquence and you being to appreciate the power of language.

I wonder if I give excessive weight to Unqualified Reservations because it has such greater facility with the English language than is typical of the blogosphere. Interesting and controversial ideas expressed with rhetorical flair seem to directly trigger the reward centres of my brain.

Is there somewhere where ideas like this are discussed intelligently?

I'm not aware of a single central hub for such discussion I'm afraid. There's academic work in the area of development economics which looks at countries around the world and tries to identify what traits of governmental institutions seem to correspond with economic growth and prosperity. This is where Paul Romer and his charter cities idea is coming from.

If you want some really out there but intelligent discussion of related ideas you might want to check out Unqualified Reservations.... (read more)

Are you familiar with the background to patrissimo's comment? Competitive government is what he's getting at in the comment you linked.

Physics provides certain tactical advantages to moon colonists. (Citing fictional evidence I know but as far as I can see the advantages are likely to be real).

I would be happy to donate money for development.

There's a lot of tools out there for task / goal tracking. I'd suggest spending some time researching them before thinking about developing a new one. Beware of falling into the trap of chasing after the elusive perfect system rather than just getting in the habit of using something good enough.

I just make a couple of fried eggs for breakfast usually. Takes less than 5 minutes and can be done in parallel with making my morning cup of tea. Advance preparation looks like overkill to me - why not just get up 3 minutes earlier?

Are you claiming that this was actually the plan all along? That our infinitely wise and benevolent leaders decided to create a panic irrespective of the actual threat posed by H1N1 for the purposes of a realistic training exercise?

If this is not what you are suggesting are you saying that although in fact this panic was an example of general government incompetence in the field of risk management it purely coincidentally turned out to be exactly the optimal thing to do in retrospect?

This looks like a fully general argument for panicking about anything.

There is nothing in what I wrote that implies people value their lives infinitely. People just need to value their lives highly enough such that flying on an airplane (with its probability of crashing) has a negative expected value.

Yes, that is the point.

Your claim that people flying on planes are engaging in an activity that has negative expected value flatly contradicts standard economic analysis and yet provides no supporting evidence to justify such a wildly controversial position. The only way your claim could be true in general would be if humans... (read more)

Population/natural resource exhaustion related crises are a bit iffy, because it is plainly obvious that if they remain exponentially growing forever, relative to linearly growing or constant resources (like room to live on), one or the other has got to give.

Obviously the people disputing the wrong predictions know this. Julian Simon was just as familiar with this trivial mathematical fact as Paul Ehrlich. The fact that this knowledge led Paul Ehrlich to make bad predictions indicates that his analysis was missing something that Julian Simon was considering. Often this missing something is a basic understanding of economics.

Well, you also need to factor in the severity of the threat, as well as the risk of it happening.

Well obviously. I refer you to my previous comment. At this point our remaining disagreement on this issue is unlikely to be resolved without better data. Continuing to go back and forth repeating that I think there is a pattern of overestimation for certain types of risk and that you think the estimates are accurate is not going to resolve the question.

In fact, people take such gambles (with negative expectation but with high probability of winning) everyday.

They fly on airplanes and drive to work.

In our world people do not place infinite value on their own lives.

I think it's hard to enjoy gambling if you are sure you'll lose money, which is how I feel like. I may be over pessimistic.

Typical Mind Fallacy.

(1) You don't have to construe the gamble as some sort of coin flips. It could also be something like "the weather in Santa Clara, California in 20 September 2012 will be sunny" - i.e. a singular non-repeating event, in which case having 100 hundred people (as confused as me) will not help you.

A coin flip is not fundamentally a less singular non-repeating event than the weather at a specific location and specific time. There are no true repeating events on a macro scale if you specify location and time. The relevant difference is how confident... (read more)
