Should we really believe that “neurological science”? They used to say white people and black people had different brains. I have lived in many countries, Western and non Western. The political polarity is different in each country. It doesn’t match with American “conservatives” and “liberals”. Does that mean each country has two tribes with different brains? I tend to believe that the political game amplifies differences in a deeply destructive way, until people see themselves — and become — different tribes who then give themselves neurological justifications for their existence. Defining your ideas neurologically, you don’t need to question yourself anymore.
