A lot of Brown's act isn't what you think. He uses psychology and hypnosis as his form of misdirection for regular tricks. He isn't actually using psychology tricks.

That is actually how all mentalism works. It's traditional stage magic that is sold as psychology as part of the act to lower the audiences guard. It's super effective. Reading books like Corindas 13 steps to mentalism blew my mind when he goes over all of the shtick and stage magic gimmicks they employ so effectively.
I'd have to agree with you about his magic tricks. He doea blur the lines a lot and it's hard to see what he really did. In that sense all of his act is a huge demonstration of misdirection. But when it comes to hypnosis, I've never seen anything more impressive
I can't find any source for this random comment's claim that they were actors, which seems like it would be pretty easy to prove. I think you've been bamboozled.
