I was thinking about something: on one hand, there’s a smidge of evidence (http://www.clubs.psu.edu/sayar/riqs.htm , Racism and Mental Health that implies that there might be a correlation between holding racist beliefs and not having everything 100% upstairs. On the other hand, there have been uncountable times throughout history where more or less everyone held said beliefs. Plus, there are depressingly many examples of intelligent racists. So, how can there be a correlation between racist beliefs and possible mental dysfunction now, but not throughout history?
My theory: In a society where you are taught that, f’rinstance, black people are inferior people, it takes at least some intelligence to notice that they are not. I would posit that it also would take some sort of disconnect with reality to conclude that black people are inhuman animals.
In summary, I am guessing that there is a statistical correlation between people who are more racist than their society and a mental disfunction of some sort. Is there any evidence either way, or possibly a logical flaw in my guess somewhere?
