Physics has long lived with a schizophrenia that desires determinism formeasured systems while demanding that experimenters decide what to measure on awhim. Intriguingly, such a free will assumption for experimenters has thwartedmany attempts to provide a satisfactory explanation of how quantumprobabilities evolve to clear-cut measurements. An overview of this quantummeasurement problem is presented without equations, and the lesson is drawnthat denial of experimenters' free will may be the only workable solutions. Ifthe free will assumption is rejected, then a door is open that may ultimatelyreconcile quantum mechanics with the definiteness of individual experiments. Aholistic view is offered for an Escher-like self-consistent space-time net ofevents rather than a conspiracy of initial conditions as a way forward.
