>>12173433you seem to think it's all about your life, but it's not. it's really about your observation. of course a bullet to your brain would fulfill that, but it's overkill.
to make this experiment non-lethal, just replace a life-stopping method with an observation-stopping method. it will be similar in that any observation-stopping attempt will have to fail for you.
for ex: there's a physicist and 2 test subjects, fire a 670nm lambda photon into a polarization beam splitter that has a 50% chance of sending the photon left, and 50% chance of sending the photon right. if the photon goes left, then it hits another 50% beam splitter, and if it goes left again then it gets sent into the left test-subject's eye (where it's measured by that subject secretly), it it doesn't, then it gets sent to the public interferometer. on the other hand, if the photon goes right, it hits another 50% splitter, and if it goes right again then it gets sent into the right test-subject's eye, else it goes to the interferometer where it will display an interference pattern (photon took multiple paths (superposition)). then, after each round, the physicist tries to determine which subject saw the photon.
why do this? because while this game seems random and fair, the theory predicts that YOU will have an advantage! you will be able to hide the photon's information from the world much better than your opponent; you already observed the photon so QM's job is done; there's no QM reason for you to also observe everyone else observe that you observed the photon as well (very meta). on the other hand, if your opponent observed the photon, then You can more easily find out since you're the observer.
Basically, QM tells us that the probability of You observing the photon PLUS you observing others observing you observe the photon (again, meta) is MUCH LOWER than someone else observing the photon without you ALSO observing them observe it.
