You can scale any distribution to have a mean of 100 and a standard deviation of 10, so I'd say it's a type error to ask whether or not the population actually matches that.
The population isn't necessarily normal, and the scaling is not necessarily done (accurately). That was my point.
Of course, distributions don't have to be normal to have a standard deviation.

I suspect that it would be obvious to most rationalists that the way people judge other people is flawed. Typically for a heuristic approach, it's correct to a degree, but with many faults. And it's wasting a big amount of information and a potential for a more planned approach where you can ask questions that assess certain qualities and exchange information about people's personalities by giving their "parameters".
I needn't think of it in this way, it was natural for me to take this approach as soon as I learnt my first measurable parameter and its implications (it was IQ). Then I explored more of them and researched them some more.
So far, I know about IQ, rationality (Keith Stanovich's), Big Five personality traits, executive functions, intuition for social situations and a few more things. However, I can't seem to find any literature that helps describe them (how do I detect them in people and what are their implications?) and their implications (how *exactly* is someone with a higher IQ different from someone with a lower IQ?). Also, I can't find literature on other traits.
Any literature on any of that would be greatly appreciated. I wonder if there is a book that deals with the whole issue. Also, I need literature about IQ and Big Five, but anything else would still be useful.
Is that sort of thing popular on LessWrong?
