People who support authoritarianism on either side of the political divide have, according to a new study, something weird going on with their brains.

Published in the journal Neuroscience, new research out of Spain's University of Zaragoza found, upon scanning the brains of 100 young adults, that those who hold authoritarian beliefs had major differences in brain areas associated with social reasoning and emotional regulation from subjects whose politics hewed more to the center.

The University of Zaragoza team recruited 100 young Spaniards — 63 women and 37 men, none of whom had any history of psychiatric disorders — between the ages of 18 and 30. Along with having their brains scanned via magnetic resonance imaging (MRI), the participants were asked questions that help identify both right-wing and left-wing authoritarianism and measure how anxious, impulsive, and emotional they were.
