it doesn't matter if he's impossible

Are you sure? I'm not objecting to the arbitrary payoffs or complaining because he doesn't seem to be maximizing his own utility. I'm objecting to his ability to predict my actions. Give me a scenario which doesn't require me to assign a non-zero prior to woo and in which a revisionist decision theory wins. If you can't, then your "improved" decision theory is no better than woo itself.

Regarding the Absent Minded Driver, I didn't recognize the reference. Googling, I find a .pdf by one of my guys (Nobelist Robert Aumann) and an LW article by Wei-Dai. Cool, but since it is already way past my bedtime, I will have to read them in the morning and get back to you.

Why? What about you is fundamentally logically impossible to predict?

Do you not find that you often predict the actions of others? (ie. giving them gifts that you know they'll like) And that others predict your reactions? (ie. choosing not to give you spider-themed horror movies if you're arachnophobic)
