CORE DEFINITION

A thought experiment: if the many-worlds theory is correct, when you play Russian roulette, in countless parallel universes, there is always a branch where you survive. From your subjective perspective, you can never die (because you cannot experience the universes where you die), and you will find yourself incredibly lucky, with the gun never firing. Scaffolding role: subjective survivor bias. It is not just a physical hypothesis, but an ultimate metaphor for "luck." If you feel you have always been lucky, it may simply be because the unlucky versions of you are no longer around. This makes us maintain a humble awe towards the fact of being alive.

Quantum suicide is a thought experiment to test the many-worlds interpretation: in an experiment with a quantum-triggered gun, the observer always exists in the "not dead" branch and thus only experiences survival, used to argue for the many-worlds interpretation.
