Over the course of the universe, the best decision theory is a consensus/multiple-evaluation theory. Evaluate which part of the universe you’re in, and what is the likelihood that you’re in a causally-unusaual scenario, and use the DT which gives the best outcome.
How a predictor works when your meta-DT gives different answers based on whether you’ve been predicted, I don’t know. Like a lot of adversarial(-ish) situation, the side with the most predictive power wins.
