There’s a variable in the GSS, GENEEXPS, which asks if genes play a role in personality. The options are:<\/p>\n

– It’s genes which play a major role<\/p>\n

– It’s experience which determines personality<\/p>\n

First, let’s admit that the premise is stupid. Personality is heritable, but environmental variation also seems to matter. In other words it is noncontroversial to assert that both<\/strong> genes and environment can explain variation in personality (or perhaps more precisely genetic variation can only explain around half the variation for any given trait).<\/p>\n

I was curious how this broke down by education and intelligence. To remove demographic confounds I limited the sample to non-Hispanic whites. For intelligence I used WORDSUM<\/a>, with scores 0-4 being dumb, 5-7 being average, and 8-10 being smart.<\/p>\n
