You don’t know what you don’t know = no free will. I still find the whole idea silly, but I like the psychological tricks he uses to be convincing.
My local county fair had a hypnotist/magician last year. I saw the show. Pretty similar stuff. Loads of fun smile emoticon He had an additional trick though; he’d get his kid to put a stick in his mouth and he’d whip off the stick ’til it was down to the last bit. You’d see the little pieces of wood go flying off somewhere and the kid wincing JUST a little at each whip. That was pretty cool. Strange but cool.
