On arm day you bulk up your arms, leg day is for the legs; these are easy to understand — what’s more complicated is that the brain can do this too. When you have experiences, create routines, and even work out (literally) your brain changes. This change is called #neuroplasticity. Over time, your reactions and your worldview together can cause parts of your brain to bulk up; gaining grey matter to compensate for the increased activity. When a neuroscientist scans your brain they see this increased grey matter on an MRI (or fMRI). Using this information, surveys, and scans of hundreds of brains scientists can create correlations that reveal how people are likely to vote. Neuroscience is WILD. On days like this, science communication is so fun.

Individual variation in preferences to maintain versus change the societal status quo can manifest in the political realm by choosing leaders and policies that reinforce or undermine existing inequalities.

Political Conservatism as Motivated Social Cognition
https://gspp.berkeley.edu/assets/uploads/research/pdf/jost.glaser.political-conservatism-as-motivated-social-cog.pdf
For more than half a century, psychologists have been tracking the hypothesis that different psychological motives and tendencies underlie ideological differences between politics: left and the right.

Political leanings vary with facial expression processing and psychosocial functioning

Conservative, Republican sympathizers show heightened threat reactivity, but greater felt happiness than liberal, Democrat sympathizers. Our internal politics is complicated!

The brain’s default network: origins and implications for the study of psychosis
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3811106/
The brain’s default network is a set of regions that is spontaneously active during passive moments. The network is also active during directed tasks that require participants to remember past events or imagine upcoming events.
