He sounds reasonable until he doesn't. My overall impression of him is that he is a mess of contradictions who is trying to have a lot of things both ways.
Maybe he thinks he's searching for a synthesis but in the end he just ends up providing what seems to be both an on ramp and an off ramp to the neo-fascist right.
The stuff that makes Peterson sound profound all comes from Jung and other similar thinkers. The good stuff is not original and the original stuff is not good. He's not even close to the worst pop intellectual around right now but he's never impressed me.
Somehow his talks about IQ seemed like the only reasonable to me.
