The hidden variables in Bohm’s pilot-wave interpretation behave in exactly this way. Particles, according to Bohm, always have positions—but those positions can be dramatically altered by small disturbances and changes in experimental setups. Ask a slightly different set of questions to an electron, in Bohm’s world, and you can get an enormously different set of answers—but the electron has a definite position all the while. And because Bohm’s theory is contextual, it evades all of the proofs that supposedly rule it out. “What is proved by impossibility proofs,” concluded Bell, “is lack of
