Welcome to Gaia! :: Liberalism, atheism, male sexual exclusivity linked to IQ | Forum

(CNN) -- Political, religious and sexual behaviors may be reflections of intelligence, a new study finds.
Evolutionary psychologist Satoshi Kanazawa at the the London School of Economics and Political Science correlated data on these behaviors with IQ from a large national U.S. sample and found that, on average, people who identified as liberal and atheist had higher IQs. This applied also to sexual exclusivity in men, but not in women. The findings will be published in the March 2010 issue of Social Psychology Quarterly.
The IQ differences, while statistically significant, are not stunning -- on the order of 6 to 11 points -- and the data should not be used to stereotype or make assumptions about people, experts say. But they show how certain patterns of identifying with particular ideologies develop, and how some people's behaviors come to be.
The reasoning is that sexual exclusivity in men, liberalism and atheism all go against what would be expected given humans' evolutionary past. In other words, none of these traits would have benefited our early human ancestors, but higher intelligence may be associated with them.

Meh, it's sociology. Weak correlation at best, with no way to control for variables as the groups are self-selected.

But IQ is better than nothing.

I disagree. Most people view it as a test of general intelligence but blacks score lower than whites and low-income people lower than well-off ones. Obviously it's a test of education more than anything inherent. I'd say it's worse than nothing if the message is being sent that people with lower IQ scores are actually less intelligent than others if these are the results.

IQ tests are useful for identifying students with learning disabilities. The test is far from perfect in anyway but it does measure intelligence, achievement, and performance. Some test are better then others for example Goodenough-Harris Drawing test is useless and if you have taken this test you should take another because it doesn't show s**t. Where as the Wechsler Intelligence Scale for Children-Revised is a good test with decently reliable results.
