I don't think so, though I often find someone has thought of the same thing I have and given it a name. The root of the issue is a matter of language. Events don't have probabilities. You don't predict a 50% chance of rain, you predict rain with a 50% certainty. (There are a lot of internet brain teasers that exploit this subtle ideological difference.) The 50% is talking about how often you're correct, not how likely the rain is to happen. Probabilities don't really exist; it either rains or it doesn't.
