What does it mean for a probability not to be well defined in this context? I mean, I think I share the intuition, but I'm not really comfortable with it either. Doesn't it seem strange that a probability could be well defined until I start learning more about it and trying to change it? How little do I have to care about the probability before it becomes well defined again?

+1 and many thanks for wading into this with me... I've been working all day and I'm still at work so can't necessarily respond in full...

I agree that these problems are a lot simpler if reducing my uncertainty about X cannot help me affect X. This is not a minor class of problems. I'd love to have better information for a lot of problems in this class. That said, many of the problems that it seems most worthwhile for me to spend my time and money reducing my uncertainty about are of the type where I have a non-trivial role in how they play out. Assuming I do have some causal power over X, I think I'd pay a lot more to know the "equilibrium" probability of X after I've digested the information the oracle gave me - anything else seems like stale information... but learning that equilibrium probability seems weird as well. If I'm surprised by what the oracle says, then I imagine I'd ask myself questions like: how am I likely to react in regard to this information... what was the probability before I knew this information such that the current probability is what it is... It feels like I'm losing freedom... to what extent is the experience of uncertainty tied to the experience of freedom?

Woh, I did allow myself to misread/misremember your initial comment a bit so I'll dial it back slightly. The fact that even at the highest levels IQ is still positively correlated to income is important, and its what I would have expected, so the overall story does not undermine my support for the hypothesis that at the highest IQ levels, higher IQ individuals produce more positive externalities. I apologize for getting a bit sloppy there.

I would guess that if you had data from people with the same job description at the same company the correlation between IQ, patents, and income would be even higher.

I wonder whether there's a correlation between depression and being conflict averse. I would guess that there is, and I'm sure there has been at least some academic study of it. This doesn't really address the issue, but its related.

I also think that keeping a blog or writing in odd corners of the internet may be associated with, possibly even caused by, depression.

Let me put it this way. Before considering the Terman data on patents you presented, I already thought IQ would be positively correlated with producing positive externalities and that there was a mostly one way causal link from the former to the latter. I expected the correlation between patents and IQ. What was new to me was the lack of correlation between IQ and income, and the lack of correlation between patents and income. Correction added: there was actually a fairly strong correlation between IQ and income, just not between income and patents, (conditional on IQ I think). Surely more productive industrial researchers are generally paid more. Many firms even give explicit bonuses on a per patent basis. So for me, given my priors, the Terman data you presented shifts me slightly against correction: does not shift me for or against the hypothesis that at the highest IQ levels, higher IQ individuals continues to be associated with producing more positive externalities. ref Still, I think increasing people's IQ, even the already gifted, probably has strong positive externalities unless the method for increasing it also has surprising (to me) side-effects.

I agree that measuring open-source contributions requires more than merely counting lines of code written. But I did want to highlight the fact that the patent system is explicitly designed to increase the private returns for a given innovation. I don't think that there is a strong correlation between the companies/industries which are patenting the most, and the companies/industries, which are benefiting the world the most.

On its own, I don't consider this strong evidence for the greater productivity of the IQ elite. If they were contributions to open-source projects, that would be one thing. But people doing work that generates patents which don't lead to higher income - that raises some questions for me. Is it possible that extremely high IQ is associated with a tendency to become "addicted" to a game like patenting?

I take it Stanovich is doing a lot of experiments where he controls for IQ, or compares performance within and across IQ groups. Here is my concern... there is always measurement error, and the more error in his measure of IQ, the more it will appear he's measuring something distinct from IQ which he terms "rationality."

That said, I also agree that IQ, and G, are often reified. The point is, I'm not sure Stanovich has succeeded in carving cognition skills at their joints, but I don't have anything better to offer.

I don't think we should push too hard on the dichotomy of boy vs. man. I would emphasize that there is individual variation in how well men they can perform/achieve masculinity in their sub-culture. Women face the issue as well.

Comment by michaelbishop on A Rational Education · 2010-06-25T21:33:08.880Z · score: 1 (1 votes) · LW · GW

For many people, their gender is an incredibly important aspect of their identity. One can think of a given subculture as having an ideal performance of masculinity. Men and women both respect that ideal. Certain occupations have been traditionally seen as very good ways of achieving that ideal. If women enter into such an occupation, the occupation is no longer seen as validating mens' manly virtues.

I oppose sex-discrimination in hiring, but there is no denying that this is a very serious loss for some men. Eventually, norms and ideals evolve in a way which allows men to continue to have their masculinity validated, and/or de-emphasizes gender as a component of one's identity, but this is a slow process. Moreover, with any change in values, there will always be winners and losers.

If you want to be on the cutting edge scientifically, you need to plan on a graduate degree. Find people doing the sort of research you are interested in and ask them for advice. Better yet, try to get a job in their lab. You'll have to get very specialized and the biggest discoveries will probably be using a different approach than whatever approach you're attempting. But hey, that's life, its honorable to give it a shot.

If you're more interested in the business, legal, or public policy, and/or education issues, then the hard science education probably isn't so important.

I plan on devoting very little time studying outside of formal lectures. (This will mean careful use of my time during lectures and all that I know on optimal learning techniques.

Personally, I learn faster studying on my own than by listening to 90% of lectures. I would think this would be especially true for a) classes at the undergraduate level and b) classes where I'm not concerned about my grade so much as I'm concerned about learning what I think is interesting/important.

I agree that GDP is imperfect. If it were easy to perfect then it would have been done already. Should more resources be devoted to the issue? Probably. I support the use of multiple measures of wealth and well-being. But I do think that when GDP goes up, that usually indicates good things are happening. Other indicators usually track it.

We were asked a sort of odd question which was which apartment choice would help the economy when not taking into account the individuals preferences about apartments. Those preferences in fact dominate the overall effect on the economy. I wouldn't recommend anyone personally attempting Keynesian stimulus.

Increasing the amount of money changing hands only helps in certain circumstances, and even then it is not necessarily the dominant effect.

I'm a sociologist*, and there is nothing sociologists like to do more than point out where economists go wrong. So if GDP was a worthless figure, I expect the real world entanglement that one of my fellow sociologists would have convinced me of that already.

I'm not saying economists never overinterpret GDP figures, and I'm not saying the consensus of macroeconomists is always correct.

Though I think we might both be better served by quitting conversation and reading actual experts (I don't claim to be one) I would like to make sure we're on the same page about the implications of your criticism.

Never once has it occurred to anyone in the mainstream (and very few outside of the mainstream) that it's okay for people to produce less, consume less, and have more leisure.

  1. Really? Because I hear economists talk about the value of leisure time quite frequently.
  2. IMO, most economists don't fetishize GDP the way you suggest they do.

I think that a majority of economists agree that in many downturns, it helps the economy if people, on the margin, spend a little more. This justifies Keynesian stimulus. Therefore, the economy would be helped if your choice increases the total amount of money changing hands, presumably if you rent the apartment for $X when X>Y. My impression is that in good economic times, marginal spending is not considered to improve economic welfare.

However, although the comfort that we experience (in the developed world) due to our modern technology is very much a product of the analytic-rational paradigm, that comfort is given roughly equally to everyone and is certainly not given preferentially to the kind of person who most contributed causally to it happening, i.e. to scientists, engineers and great thinkers.

How much have scientists and engineers contributed to our standard of living? Probably a good amount, but why do we have scientists and engineers? My impression is that our current high standard of living is due to the fact that most people are rational, in certain domain specific ways. Namely, they adopt better tools when given the opportunity. They specialize and trade. It seems quite possible that ambitious entrepreneurs, rather than thoughtful rationalists deserve the most credit for past progress.
