Kavka's toxin puzzle, introduced by philosopher Gregory Kavka, explores the concept of rational commitment. The scenario involves a person who faces a choice: to drink a harmless but distinctive toxin today with the promise of a substantial reward tomorrow if they do, or abstain from drinking. The puzzle challenges traditional economic and game theory notions of rationality, questioning the role of one's beliefs and intentions in decision-making. It serves as an intriguing thought experiment in the realm of philosophical discussions on rationality and decision theory. (AI)
