Rosalee, I believe they act that way because they choose to. Unscientific and old fashioned of me I know. IQ, height, bone size, hair color are hereditary traits. But good and evil are not. Poor cognitive skills are not the same as greed, violence, or the burning desire to control others. As far as those traits go I guess not-so-bright underdogs can have them too. But they hurt far fewer people than intelligent, highly educated medical experts lacking conscience and compassion. Most people with low intelligence I know are unusually sweet and kind. Their warm, generous hearts should put the smarties to shame. Attributing wickedness to weakness and stupidity (aka bad genes) doesn’t cut it. Hitler did not start World War II because of weakness or stupidity. Weakness is not a crime. But the APA has basically classified it as such.
