Red brain, blue brain: republicans and democrats process risk differently, research finds.
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.
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.
