Political Orientations Are Correlated with Brain Structure in Young Adults. Curr Biol. 2011 Apr 26; 21(8): 677-680

The study by Kanai et al. examined the correlation between political orientation and brain structure in young adults.

The researchers found that the thickness of the anterior cingulate gyrus, a brain region involved in conflict processing and error monitoring, correlates with liberal political beliefs. In contrast, the thickness of the right posterior superior temporal sulcus, a brain region involved in processing visual information, correlated with conservative political beliefs.

The results suggest that there are differences in brain structure that could be linked to different political beliefs and behaviors. However, the authors emphasize that further studies are needed to clarify whether these differences are indeed causally related to political orientation or possibly due to other factors.
