Somewhat in my defense, although I've seen a few clips with Rogan, I'm not very familiar with him. I agree with the GP's comment, I thought the real Joe Rogan reading ads sounded very staccato and robotic. Near the end I got a little better with the "OK, robotic sounding Joe is the real one."
That said, I'm an introvert and I don't enjoy social situations with people I don't know, so while perhaps not a psychopath it's plausible the my poor ability to infer emotional intonation is at play both here and in social situations.
