What you describe matches some of his interviews. It really varies by topic, how much he is personally interested in it and how much research he has done. Some of the dopey persona is an act to put himself a few rungs lower than the guest and it seems to work most of the time.
Are we watching the same person? I like Rogan's interviews, but he draws out good content by being dopey and asking simple questions, not by being charismatic and deep.
