Liberalism, atheism, male sexual exclusivity linked to IQ

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.

"The adoption of some evolutionarily novel ideas makes some sense in terms of moving the species forward," said George Washington University leadership professor James Bailey, who was not involved in the study. "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."

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 7-12 in the United States during the 1994-95 school year. The participants were interviewed as 18- to 28-year-olds from 2001 to 2002. 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.

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.

"Historically, anything that's new and different can be seen as a threat in terms of the religious beliefs; almost all religious systems are about permanence," he noted.

The study takes the American view of liberal vs. conservative. It defines "liberal" in terms of concern for genetically nonrelated people and support for private resources that help those people. It does not look at other factors that play into American political beliefs, such as abortion, gun control and gay rights.

"Liberals are more likely to be concerned about total strangers; conservatives are likely to be concerned with people they associate with," he said.

Given that human ancestors had a keen interest in the survival of their offspring and nearest kin, the conservative approach -- looking out for the people around you first -- fits with the evolutionary picture more than liberalism, Kanazawa said. "It's unnatural for humans to be concerned about total strangers." he said.

The study found that young adults who said they were "very conservative" had an average adolescent IQ of 95, whereas those who said they were "very liberal" averaged 106.

It also makes sense that "conservatism" as a worldview of keeping things stable would be a safer approach than venturing toward the unfamiliar, Bailey said.

Neither Bailey nor Kanazawa identify themselves as liberal; Bailey is conservative and Kanazawa is "a strong libertarian."

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.

None of this means that the human species is evolving toward a future where these traits are the default, Kanazawa said.

"More intelligent people don't have more children, so moving away from the trajectory is not going to happen," he said.

The difference in IQ is hardly enough to make those wild determinations.

I've always felt that religious people are just the same as UFO believers or Bigfoot believers. They believe it because they want to. It has little to do with intelligence.

For example, look up videos of the SETI project. The people that run it are intelligent, yet they use their expertise and intelligence to look out for aliens. It's their choice.

In other words, people who are open minded, utilize critical thinking skills, and don't need the fear of a vengeful sky god to coerce them into caring for others tend to have higher IQs?

Not getting any controversy from this.

The study makes sense to me.

I'm leaving myself out of this discussion. Although, it has caused some laughter around my apartment.

I didn't need to be told this. It's nice there's some evidence. My brother had a 2004 Presidential race break-down, state-by-state, by IQ a couple of years ago. You can predict by IQ who would pull the lever for President Bush and who would vote for John Kerry. It was scary--his point was that Karl Rove's campaign appealed to our baser instincts. Fear and danger and uncertainty and change in the face of it.
With expectation comes responsibility. Respect is earned. When opportunity arises, preparation will calm nerves, inspire confidence, and help you to realize the moment. Where there is failure is a blueprint of how to improve. To fail to learn, even with talent, makes you ordinary. To learn from all experiences is to learn to become the best.
