Intelligence and political views: link between high IQ and liberalism in men

Research in evolutionary psychology and neuroscience suggests a correlation between higher intelligence and political ideology, particularly among men. Studies indicate that men with higher IQ scores tend to be less conservative, often leaning toward liberal or progressive values.

Evolutionary psychologist Satoshi Kanazawa has proposed a hypothesis suggesting that general intelligence (the g-factor) assists individuals in navigating evolutionarily new situations or ideas. While conservatism focuses on maintaining tradition, stability, and established social hierarchies, liberal and progressive ideas involve re-evaluating traditions and accepting novel social concepts. According to Kanazawa's research, individuals with higher IQs, especially men, process these newer concepts more easily.

In personality psychology, the trait of "Openness to Experience" from the Big Five model serves as a key link. This trait is strongly associated with both higher intelligence and liberal political views, characterized by intellectual curiosity and a tendency to question authority.
