When asked to choose between two competing theories, A and B, each of which fits the facts, people will sometimes resort to asking questions like, "Which theory is the more probable?" or "Which theory is simpler?" or even "Which theory involves the least upset to all my other beliefs?" Well, what about, "Which is the less weird theory?" Could weirdness (that is, something like distance from everyday experience) count as a good criterion on which to endorse one theory over another? Einstein seems to be appealing to some idea like this in the comment that God doesn't play dice. And would it be fair to say that many philosophers appeal to something like this when they reject panpsychism?
Philosopher John Haugeland once offered a sort of counterpart to Ockham's razor: "Don't get weird beyond necessity." (from "Ontological Supervenience," 1984, Southern Journal of Philosophy pp. 1—12.) Of course, the hard part is spelling out what weirdness amounts to and why it counts against a hypothesis. For example: Ockham's Razor tells us not to multiply entities beyond necessity: it stands in favor of parsimonious theories. Panpsychism is certainly weird, but from one point of view it's parsimonious: it says that there aren't actually two kinds of physical things (conscious and unconscious) but only one. Does the weirdness swamp the parsimony? If so why? So as a quick and dirty rule of thumb, "Pick the less weird theory" seems fine. As a serious methodological rule, it may need some work.
