The brain tonsils of conservative voters are the size of a sesame seed, or slightly larger than those of progressive voters, according to a study. a study published this Thursday in the journal Cell Press iScience.

Brain scan analysis team for MRI of 928 people between 19 and 26 years old with education levels and political identities typical of the Dutch population. The results have confirmed that people’s amygdala size is related to their political opinions.

The anatomical differences they observed in the amygdala and anterior cingulate cortex (ACC) change depending on the economic and social status of the person, indicating that the relationship between political opinion and brain structure is “nuanced and multidimensional”, the study pointed out. For Diamantis Petropoulos, the first author and researcher at the American College of Greece and the University of Amsterdam, “it is really surprising that r.We will publish the discovery of the amygdala. “We didn’t expect it.”

Different ideas, different minds

As the Netherlands has a multi-party political system, the survey is also needed compare its effect on the brainin contrast to the UK two-party system, and analyze the ‘opinion’ of the participants from different angles and various economic issues.

To do this, they gave the participants a questionnaire with questions about them social and economic identity (how they see themselves on the sliding scale from progressive to conservative, and which political party they identify with), the social and economic ideology (what is your position on various social and economic issues, such as women’s rights and LGBQT, income inequality and benefit sharing).

Them relationship between amygdala size and conservatism It also depends on the political party that the individual identifies with; For example, participants who identify with the socialist party, which has poor economic policies but more conservative social values, have on average more gray matter in the amygdala than those of other progressive parties.

The MRIs used in this study only provide information about the anatomy of different brain areas, but the researchers believe that future work will need to add information about the functional connections between the amygdala and different parts of the brain.
