In fact, there is a scientific explanation. The tonsils of the brain of conservative voters are approximately the size of a sesame seed, that is, slightly larger than those of progressive voters, according to a study published in the journal Cell Press iScience.

The amygdala controls the perception and understanding of threats and uncertainty in the face of risk, so it makes a lot of sense that people more sensitive to these issues have a greater need for security, something that usually coincides with more conservative political ideas.

The relationship between the size of the amygdala and conservatism also depended on the political party with which the individual was identified.
