Like Shminux, I say: Why not all three? You’ve just very helpfully pointed out that there are different ways in which someone can be predictable. So going forward, when I contemplate decision theory hypotheticals in which someone is predictable, I’ll make sure to specify which of these three kinds is in effect. Usually I’ll consider all three kinds, to see if it changes the results.
