He doesn't have empirical evidence. I believe he's so used to his every word being accepted as fact from his fan club, he's forgotten that other people can see right through the nonsense he posts! It's a shame, as I'm sure without the cloak of insults and ignorance, he could actually have some constructive ideas to share.

I actually toyed with the idea of going in to psychology (with a focus on language) before deciding on literature instead. Psychology, specifically the psychology behind communication, has always fascinated me though, and I do try to keep up with my reading on the subject. Learned response is an area of great interest to me.
