For a long time, the claim has been made that the brains of conservative people are different than those of progressives.
University of Amsterdam Sep 20 2024 Using MRI scans of almost 1,000 Dutch people, researchers from the University of Amsterdam show that there is indeed a connection between brain structure and ideology. However, the connection is smaller than expected. Nevertheless, the researchers find it remarkable that differences in the brain are linked to something as abstract as ideology.
The researchers analyzed the MRI scans of 975 Dutch people aged 19 to 26, representing a cross-section of the Dutch population in terms of education and political preference. They linked these scans to questionnaires about ideology. The scientists also found that there is no relationship between another brain area - the anterior cingulate cortex - and ideology, something that the original study did find.

'The amygdala has mainly been studied in relation to threatening situations and fear, but seems to respond much more broadly to emotions in general and to divergent information.
