it's not about bayes for me, it's that within context, it's overwhelmingly likely that I'm the butt of a practical joke, so if I press red and don't get my million, at least I can call out the experimenter on it
normal person intuition: "hmm idk seems fucky I'll press red so they can't weasel out"
math brainworms: "haha you're dumb for not buying the premise that someone out there wants to give you $1M+ with no strings attached"
