What would you call the thing where it turns out that all my morality-flavoured wants are nonsense, but all my selfish-flavoured wants still make sense? Can we sub that term into the OP in place of ‘nihilism’?
Or do you deny the premise that there are different flavours? I personally really feel like I can taste the flavours.
In my experience even smart people need a bit of conversational back and forth to understand the setup for Newcomb’s problem, so I’m a bit skeptical that most survey respondents can grok it from a concise description.
I wonder how the results would be different if a human or AI did enough back and forth with each participant to make sure they understand the setup.
