Surely this just tests for freethinking and non-conformity. Much like Milgram and Asch found.

About a third of people are highly suggestible and agreeable, they readily follow authority, fall for scams and can be hypnotised. About a third cannot be easily conned or hypnotised, are vigilant, "disagreeable" and likely to go their own way.

Even of that highly sceptical, independent third, it takes a lot of courage to say "I totally know this is bullshit, and I'm done". Only a handful of Migram's subjects were able, not just to assert a moral objection to hurting a fellow human being, but to question or see through the whole ruse of fake scientists and stooges. Even if you can spot that, it takes rather a rare human to act on it, to call it out and walk away - or rather escape the parameters (get outside the box) you've been placed within.
