“Newcomb Problems and Unstable Decisions ” by Prof. Joe Horton
26 Feb 2024

Hybrid Research Seminar

There has recently been a surge of interest in a new kind of decision theory, which we can call Hindsight Decision Theory (HDT). Its proponents include Ralph Wedgwood, J. Dmitri Gallow, Abelard Podgorski, and David James Barnett. They argue that HDT avoids problems with both Evidential Decision Theory (EDT) and Causal Decision Theory (CDT). I here argue that the main problem with EDT, known as the Newcomb Problem, also applies, with no less force, to HDT. I then offer a novel defence of CDT, and I end by clarifying the relationship between my defence and the idea of deliberation dynamics.
