What is logical decision theory?

Logical Decision Theory (LDT) is a concept introduced by Eliezer Yudkowsky. It diverges from classical decision theories by incorporating elements of logical and mathematical structures to analyze decisions, particularly in scenarios involving highly intelligent agents or superintelligences. Instead of relying purely on causal or evidential considerations, LDT emphasizes logical consistency and coordination among agents, even when direct causal interactions are absent 1.

Yudkowsky suggests that rationality should be viewed as systematized winning where rational agents do not make predictable errors due to irrational opponents. This contrasts with causal decision theory, which can lead rational agents to lose in specific scenarios because they fail to account for the logical dependencies in their decisions 1.
