SCIENCE DAILY– We all know that people at opposite ends of the political spectrum often really can’t see eye to eye. Now, a new report published online on April 7th in Current Biology, reveals that those differences in political orientation are tied to differences in the very structures of our brains.
Individuals who call themselves liberal tend to have larger anterior cingulate cortexes, while those who call themselves conservative have larger amygdalas. Based on what is known about the functions of those two brain regions, the structural differences are consistent with reports showing a greater ability of liberals to cope with conflicting information and a greater ability of conservatives to recognize a threat, the researchers say.
“Previously, some psychological traits were known to be predictive of an individual’s political orientation,” said Ryota Kanai of the University College London. “Our study now links such personality traits with specific brain structure.”
Kanai said his study was prompted by reports from others showing greater anterior cingulate cortex response to conflicting information among liberals. “That was the first neuroscientific evidence for biological differences between liberals and conservatives,” he explained.
