I actually don't believe this is true, for most mechanisms of "mysterious future knowledge", including most (philosophical) forms of time travel that don't allow change. Unless I had some specific details about the mechanism of prediction that changed the situation I would go ahead and try very hard despite knowing it is futile. I know this is a total waste... it's as if I am just leaving $10,000 on the ground or something! (ie. I assert that newcomblike reasoning applies.)
I don't understand this.
In Newcomb's problem, Omega knows what you will do using their superintelligence. Since you know you cannot two-box successfully, you should one-box.
If Omega didn't know what you would do with a fair degree of accuracy, two-boxing would work, obviously.
Not if you mistakenly believe, as CDTers do, in human free will in a predictable (by Omega) universe.
"Free will" isn't incompatible with a predictable (by Omega) universe. I also doubt that all CDTers believe the same thing about human free will in said universe.
