Intelligence Study Links Low I.Q. To Prejudice, Racism, Conservatism
The study, published in Psychological Science, showed that people who score low on I.Q. tests in childhood are more likely to develop prejudiced beliefs and socially conservative politics in adulthood.
I.Q., or intelligence quotient, is a score determined by standardized tests, but whether the tests truly reveal intelligence remains a topic of hot debate among psychologists.
Dr. Gordon Hodson, a professor of psychology at the university and the study's lead author, said the finding represented evidence of a vicious cycle: People of low intelligence gravitate toward socially conservative ideologies, which stress resistance to change and, in turn, prejudice, he told LiveScience.
Why might less intelligent people be drawn to conservative ideologies? Because such ideologies feature "structure and order" that make it easier to comprehend a complicated world, Dodson said. "Unfortunately, many of these features can also contribute to prejudice," he added.
