It is the obvious rational strategy... which is why using a decision theory that doesn't get this wrong is important.
Yup yup, you're right, of course.
What I was trying to say, then, is that I don't understand why there's any debate about the validity of a decision theory that gets this wrong. I'm surprised everyone doesn't just go, "Oh, obviously any decision theory that says two-boxing is 'rational' is an invalid theory."
I'm surprised that this is a point of debate. I'm surprised, so I'm wondering, what am I missing?
Did I manage to make my question clearer like that?
I can say that for me personally, the hard part - that I did not get past till reading about it here - was noticing that there is actually such a variable as "what decision theory to use"; using a naive CDT sort of thing simply seemed rational /a priori/. Insufficient grasp of the nameless virtue, you could say.
Meaning you're in the same boat as me? Confused as to why this ever became a point of debate in the first place?
...no? I didn't realize that the decision theory could be varied, that the obvious decision theory could be invalid, so I hit a point of confusion with little idea what to do about it.
But you're not saying that you would ever have actually decided to two-box rather than take box B if you found yourself in that situation, are you?
I mean, you would always have decided, if you found yourself in that situation, that you were the kind of person Omega would have predicted to choose box B, right?
I am still so majorly confused here. :P
I have no idea! IIRC I leaned towards one-boxing, but I was honestly confused about it.
Ahah. So do you remember if you were confused in yourself, for reasons generated by your own brain, or just by your knowledge that some experts were saying two-boxing was the 'rational' strategy?
