Schrödinger's cat

This is where my avoidance of mathematics bites me in the ass.

I wanted to claim that Schrödinger's cat is actually a fable of learned men refusing to believe facts about the world.

But if that claim is true, then we must be able to apply the Born rule to all subjective probabilities, not just the quantum ones. (I think frequentist probabilities shouldn't count because it's just measuring the results?)

Now, then, it seems I'll have some reading to do.... :-/
