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.
Bailey also said that these preferences may stem from a desire to show superiority or elitism, which also has to do with IQ. In fact, aligning oneself with "unconventional" philosophies such as liberalism or atheism may be "ways to communicate to everyone that you're pretty smart," he said.
The study looked at a large sample from the National Longitudinal Study of Adolescent Health Add Health , which began with adolescents in grades in the United States during the school year. The participants were interviewed as to year-olds from to The study also looked at the General Social Survey , another cross-national data collection source. Kanazawa did not find that higher or lower intelligence predicted sexual exclusivity in women. This makes sense, because having one partner has always been advantageous to women, even thousands of years ago, meaning exclusivity is not a "new" preference.

In the current study , Kanazawa argues that humans are evolutionarily designed to be conservative, caring mostly about their family and friends, and being liberal, caring about an indefinite number of genetically unrelated strangers they never meet or interact with, is evolutionarily novel.
So more intelligent children may be more likely to grow up to be liberals. Young adults who subjectively identify themselves as "very liberal" have an average IQ of during adolescence while those who identify themselves as "very conservative" have an average IQ of 95 during adolescence. Similarly, religion is a byproduct of humans' tendency to perceive agency and intention as causes of events, to see "the hands of God" at work behind otherwise natural phenomena.
This innate bias toward paranoia served humans well when self-preservation and protection of their families and clans depended on extreme vigilance to all potential dangers.
Young adults who identify themselves as "not at all religious" have an average IQ of during adolescence, while those who identify themselves as "very religious" have an average IQ of 97 during adolescence.
In addition, humans have always been mildly polygynous in evolutionary history. Men in polygynous marriages were not expected to be sexually exclusive to one mate, whereas men in monogamous marriages were.
