It is fairly hard to perform such checks. We don't have many situations which are analogous to Newcomb's problem. We don't have perfect predictors and most situations humans are in can be considered "iterated". At least, we can consider most people to be using their 'iterated' reasoning by mistake when we put them in once off situations.
The closest analogy that we can get reliable answers out of is the 'ultimatum game' with high stakes... in which people really do refuse weeks worth of wages.
By the way, have you considered what you would do if the boxes were transparent? Just sitting there. Omega long gone and you can see piles of cash in front of you... It's tricky. :)
Thanks, but I meant not a check on what these CDT-studying-type people would DO if actually in that situation, but a check on whether they actually say that two-boxing would be the "rational" thing to do in that hypothetical situation.
I haven't considered you transparency question, no. Does that mean Omega did exactly what he would have done if the boxes were opaque, except that they are in fact transparent (a fact that did not figure into the prediction)? Because in that case I'd just see the million in B, and the thousand in A, and of course take 'em both.
Otherwise, Omega should be able to predict as well as me that, if I knew the rules of this game were that, if I decided to predictably choose to take only box B and leave A alone, box B would contain a million, and both boxes are transparent (and this transparency is figured into the prediction), I would expect to see a million in box B, take it, and just walk away from the paltry thousand in A.
This make sense?
