The research finds that children with low intelligence are more likely to hold prejudiced attitudes as adults. These findings point to a vicious cycle, according to lead researcher Gordon Hodson, a psychologist at Brock University in Ontario. Low-intelligence adults tend to gravitate toward socially conservative ideologies, the study found. Those ideologies, in turn, stress hierarchy and resistance to change, attitudes that can contribute to prejudice, Hodson wrote in an email to LiveScience.
“Prejudice is extremely complex and multifaceted, making it critical that any factors contributing to bias are uncovered and understood,” he said.
The findings combine three hot-button topics.
“They've pulled off the trifecta of controversial topics,” said Brian Nosek, a social and cognitive psychologist at the University of Virginia who was not involved in the study. “When one selects intelligence, political ideology and racism and looks at any of the relationships between those three variables, it's bound to upset somebody.”
Polling data and social and political science research do show that prejudice is more common in those who hold right-wing ideals that those of other political persuasions, Nosek told LiveScience.
