There have been various academics who have discussed decision theory before MIRI even came into existence. I don’t know if they’re actually working on improving things, though. My sense is that they’ve mostly been just been sticking with causal decision theory and evidential decision theory. But there’s probably at least some work done improving.
Is MIRI an only research institution in the world which is working on patching decision theory and other listed issues?
