My best guess is . . . the selection [pressure on 'g' in Ashkenazim] being from some trait other than 'g' which is much more enhanced by the alleles in question than 'g' is and which correlates with 'g'. The personality trait Openness would be a good candidate for such a trait.

Interesting conjecture, Michael Vassar. A very salient characteristic of younger Eliezer's writings is great openness -- about things like his history and his internal thought processes. I have been trying to be more open, except when I talk to Muggles, in which case I have been trying to be more circumspect in my speech and not to volunteer negative information about myself.
