If anything, I think you could argue that the Holocaust contributed to a higher than average Jewish IQ rather than the other way around. I'm sure Jews able to avoid fatal persecution in WWII and in the USSR have several qualities highly correlated with intelligence. An environment which values education and teaches what is being tested helps explain lots of the results of the cited paper (chess in particular is very much a learned game, not one of raw general intelligence) as well as the tendency for small groups in a population to engage in all types of preferential and assistive behavior towards members of the same group (in particular, academia as in the cited paper). Where am I going with this? Perhaps several of the social psychological cognitive biases (in group/out group bias, attribution theory, etc.) are good examples of advantageous "evolutionary stupidity" as biases add no or even detract from relevant information yet help guarantee irrational or even rational outcomes (even if for uncalculated reasons) that may benefit the group and individual.
As for the original post -- I would imagine the selection going on outside of the game would help guarantee that the situation described does not usually occur. But finding examples of say, the "dumb" players all together having chased the "smart" players out due to coalition or other behavior would be interesting. Ideas? (Maybe penny stock traders?)

Perhaps the first set of situations is more important than you think. For example, could the Holocaust (and anti-semitism in general) fall into that category, given that Jews have a higher average IQ than gentiles? (116 vs 100, according to http://www.lagriffedulion.f2s.com/ashkenaz.htm.)

I'd argue no, at least beyond a certain degree, because if you have sufficient general intelligence, you can apply it to any area but still fake being dumb in particular areas. The only way to convince others of actually being dumb in those areas is to be dumb in general.

Do you have any evidence for this? At least personally I find economics easier to understand than, say, string theory, or even electromagnetism.
