LessWrong post maps all decision theories, reveals entangled axes
A 50-minute read that unifies Newcomb, FDT, and UDT into a single provably entangled grid
Deep Dive
In a LessWrong post, Ihor Kendiukhоv proposes a map of decision theories built on three separate axes: what we suppose when considering a candidate action, how
Key Points
- The post decomposes decision theory into three semi-orthogonal axes: suppositions about actions, gamble scoring, and pre- vs post-information choice.
- It maps existing theories like EDT, CDT, FDT, and Wei Dai's UDT onto a grid, with theorems proving the axes are entangled.
- Includes an AI-generated technical appendix with formal proofs and open problems, explicitly marked as 'no guarantee.'
Why It Matters
A unified map of coherent decision theories could sharpen AI alignment's foundations for agent design and safety.
