> If I didn't know the experimenter was trustworthy (for example a street hustler in NYC), I definitely would not switch in the equal reward scenario and may even require 3x to switch because I would expect that they would only offer if my initial selection was wrong. If you don't trust the experimenter at all, then you might as well not switch, but I don't think that is a better than switching, as you have no basis for assuming any outcome in any circumstance. If you are dealing with a street hustler in NYC, the optimal move is to disengage. WRT the first (equal rewards) scenario: a weak bias towards sticking with an original decision might be favored by evolution, as constantly changing one's mind without new knowledge is not optimal behavior.
