“The adoption of some evolutionarily novel ideas makes some sense in terms of moving the species forward…It also makes perfect sense that more intelligent people — people with, sort of, more intellectual firepower — are likely to be the ones to do that.”

Quoting a story from CNN on a recent study that found “on average, people who identified as liberal and atheist had higher IQs. This applied also to sexual exclusivity in men, but not in women.”

“For men, on the other hand, sexual exclusivity goes against the grain evolutionarily. With a goal of spreading genes, early men had multiple mates. Since women had to spend nine months being pregnant, and additional years caring for very young children, it made sense for them to want a steady mate to provide them resources.
Religion, the current theory goes, did not help people survive or reproduce necessarily, but goes along the lines of helping people to be paranoid, Kanazawa said. Assuming that, for example, a noise in the distance is a signal of a threat helped early humans to prepare in case of danger.
“It helps life to be paranoid, and because humans are paranoid, they become more religious, and they see the hands of God everywhere,” Kanazawa said.
Participants who said they were atheists had an average IQ of 103 in adolescence, while adults who said they were religious averaged 97, the study found. Atheism “allows someone to move forward and speculate on life without any concern for the dogmatic structure of a religion,” Bailey said.”

“Vegetarianism, while not strongly associated with IQ in this study, has been shown to be related to intelligence in previous research, Kanazawa said. This also fits into Bailey’s idea that unconventional preferences appeal to people with higher intelligence, and can also be a means of showing superiority.”
