If you find Peterson interesting, it's worth listening to his two interviews with Sam Harris on Harris's podcast. The first is so hilarious (in a bad way, albeit) that it'll make you want to punch your own face - esp. the part where Peterson won't admit something is "true" if it leads to the extinction of the human race.
it was a bad interview and Peterson's cantankerousness got the better of him during that segment. The second interview is more worthwhile, and the two of them have an interesting discussion about what sorts of concepts they respectively like to address with the notion of "truth". Peterson is not anti-evidence or anti-rationalist at all, but he does more broadly include psychological and archetypal patterns as truths.
The best interview I've heard with him was on The Duncan Trussell Family Hour[1]. I haven't heard the Sam Harris interview but I could see it being frustrating. I think Peterson is at his best when he can speak in — and about — metaphor. Sam's podcast doesn't seem like an ideal place for that.
