So, I feel like I might have shared this before, but there was a study done where participants were placed under fMRI while watching the Trump vs. Clinton debate. It showed that there was more similarity in the scans of people from different parties while watching their non-preferred candidate, than those of people watching the candidate they preferred within the same party.

Also, it lit up a part of the brain that is self-referential. The basic hypothesis was that people were making comparisons to themselves and viewing the opposite candidate as part of an out group.

Maybe the younger generation can't relate to the older generation at all.
