What Made You Vote the Way You Did?

A team of political scientists and neuroscientists has shown that liberals and conservatives use different parts of the brain when they make risky decisions, and these regions can be used to predict which political party a person prefers. The new study suggests that while genetics or parental influence may play a significant role, being a Republican or Democrat changes how the brain functions.

Researcher Darren Schreiber is studying the differences in the way the brain functions in American liberals and conservatives.

In a prior experiment, participants had their brain activity measured as they played a simple gambling game. Dr. Schreiber and his UC San Diego collaborators were able to look up the political party registration of the participants in public records. Using this new analysis of 82 people who performed the gambling task, the academics showed that Republicans and Democrats do not differ in the risks they take. However, there were striking differences in the participants' brain activity during the risk-taking task.

Democrats showed significantly greater activity in the left insula, a region associated with social and self-awareness. Meanwhile Republicans showed significantly greater activity in the right amygdala, a region involved in the body's fight-or-flight system. These results suggest that liberals and conservatives engage different cognitive processes when they think about risk.

In fact, brain activity in these two regions alone can be used to predict whether a person is a Democrat or Republican with over 80% accuracy. By comparison, the longstanding traditional model in political science, which uses the party affiliation of a person's mother and father to predict the child's affiliation, is only accurate less than 70% of the time.

Saying "Democrat or Republican" is ridicules. That's like saying "Your favorite food: cheeseburger or meatballs". Like there is nothing else. Get some youth parties, old parties, immigration stop parties, fiscal order parties, green parties etc. like we have in many european countries.
The english 2 chamber systems sucks.

I'm surprised that there's any difference at all in the brains of Republicrats and Demoblicans. Both parties give us war, deficits, and the shredding of the Bill of Rights.
