Study Links Low I.Q. To Prejudice, Racism, Conservatism

Is Racism Just a Form of Stupidity?

Longitudinal studies provide some of the most convincing evidence. One such study looked at general intelligence in 10- and 11-year-old kids, and then re-studied those kids as adults two decades later—and found a clear connection between low intelligence and subsequent racism and sexism. Similarly, higher intelligence in childhood has been shown to predict less racism in adulthood. These analyses strongly suggest that low intelligence actually leads to hateful attitudes later on.

This is just a sampling of the accruing evidence on this point, all of which points to another puzzling question: Why? Why would verbal ability and math skills and other cognitive assets translate, over the years, into such hateful attitudes?

Dhont and Hodson believe they have an answer to this, again one based on rigorous abundant evidence. Their theory is that right-wing ideologies attract people with lower mental abilities because they minimize the complexity of the world. Right-wing ideologies offer well-structured and ordered views of society, views that preserve traditions and norms, so they are especially attractive to those who are threatened by change and want to avoid uncertainty and ambiguity. Conversely, smart people are more capable of grasping a world of nuance, fluidity and relativity.
