Alicorn:

It's not really too late then. Omega can predict what you'll do between seeing the boxes, and choosing which to take. If this is going to include a decision to take one box, then Omega will put a million dollars in that box.

TobyBartels:

If you say this, then you believe in backwards causality (or a breakdown of the very notion of causality, as in Kevin's comment below). I agree that if causality doesn't work, then I should take only Box B, but nothing in the problem as I understand it from the original post implies any violation of the known laws of physics.

I remember reading an article about someone who sincerely lacked respect for people who were 'soft' (not exact quote) on the death penalty ... before ending up on the jury of a death penalty case, and ultimately supporting life in prison instead. It is not inconceivable that a sufficiently canny analyst (e.g. Omega) could deduce that the process of being picked would motivate you to reconsider your stance. (Or, perhaps more likely, motivate a professed one-boxer like me to reconsider mine.)
