Researchers at the University of California, San Diego say they’ve found the first genetic marker that can identify someone’s political views.

…the researchers were able to show that people with a specific variant of the DRD4 gene were more likely to be liberal as adults, but only if they had an active social life in adolescence.

Dopamine is a neurotransmitter affecting brain processes that control movement, emotional response, and ability to experience pleasure and pain. Previous research has identified a connection between a variant of this gene and novelty-seeking behavior, and this behavior has previously been associated with personality traits related to political liberalism.

Lead researcher James H. Fowler of UC San Diego (pictured) and his colleagues hypothesized that people with the novelty-seeking gene variant would be more interested in learning about their friends’ points of view. As a consequence, people with this genetic predisposition who have a greater-than-average number of friends would be exposed to a wider variety of social norms and lifestyles, which might make them more liberal than average. They reported that “it is the crucial interaction of two factors — the genetic predisposition and the environmental condition of having many friends in adolescence — that is associated with being more liberal.” The research team also showed that this held true independent of ethnicity, culture, sex or age.

It would seem that exposure to different societal elements makes one more liberal; the less sheltered, the more open you are, the more liberal you are.
