Actually I was thinking about Schrödinger’s cat and how most people misunderstand that thought experiment. Erwin Schrödinger presented that thought experiment as a way to illustrate how different Heisenberg’s quantum uncertainty principle was to the behavior of macroscopic objects. You see, if you really tried the Schrödinger’s cat experiment (and it’s worth nothing that experimental physicists have tried versions of it that didn’t involve risk to our feline overlords), decoherence would collapse the uncertainty of the uranium-sample decay before it ever influenced the observable outcome of the cat’s safety (whether or not that decoherence goes another way in a parallel universe is a separate debate).
