Some have pointed out that IQ may be underestimated because everyone in the sample scored above the top .5%
Also, notice that the sample is men. Do women differ significantly?
Notice that the positive effects of IQ kick in around 30. Also the negative effects of agreeableness kick in around 35.
It is my understanding that conscientiousness/openness maps onto conservatism/liberalism quite well, explaining why conservatives make more.
Perhaps the most surprising to me is the importance of extraversion! Why haven't I heard about this before?
