I've been reading stuff by philospher Wolfgang Spohn. His recent decision theory stuff (like Dependency equilibria and the causal structure of decision and game situations or Reversing 30 years of discussion: why causal decision theorists should one-box) is kind of cool. Like TDT, he talks about rational agents deciding on the basis of "reflexive entangled decision situations" and like UDT he proposes that agents should decide to follow the decisions they would have made in "earlier situations". It's not quite LW style reductionism, but it's close-ish, and it increases my estimation that LW decision theory would be well recieved in academia (after a little self promotion).
