“Opposing political views may be linked to differences in brain structures, a new study suggests.
“Researchers at University College London found that liberals tend to have a larger anterior cingulate cortex, while conservatives have a larger amygdala.
“Based on what’s known about the roles of these two areas of the brain, the structural differences are consistent with previous studies that found liberals are better able to cope with conflicting information and are more open to new experiences, while conservatives are better able to recognize a threat and more anxious when faced with uncertainty, according to team leader Ryota Kanai and colleagues.”
