If psychologists are just now learning about 'personality' then whats with all their BS 'personality disorders' that obviously predate your understanding of what the hell you're talking about?

Oops, you unmasked yourself! Here's some truth for you - psychologists are the narcissists. You think you know it all and you're just human. Your theories weren't handed down on stone tablets. You make them up, congratulate each other for your cleverness in your little hothouse world of out-of-touch academia; you invent heroes out of each other and then worship yourselves even more. If you could only see yourselves from the bleachers. It's a clown show.
