In Response To: My favourite probability problem (poseidon)

Does it matter that taking both envelopes is a dominant strategy? That is, if you take the $1,000, you are always $1,000 better off no matter what the predictor's prediction was.

Given this knowledge can you still rationally choose to take only the $1m envelope?
