From experience, niggas who get degrees on psychology are either super sweet or the most insufferable narcissist people ever
At least in my case, I have a cousin who has attempted to -ACK! like twice, whose mom is a psychologist, and is very emotionally absent and strict. He's been grounded for even laughing. And my dad has a psychologist degree too.
I think on the other side, people might be more interested in psychology related stuff if they have a history of mental illness in the family, which is why their kids might end up having some retardation too.
