Actually, James, I read something wild into your sentence, interpreting "competition" as the selection mechanism. That does strike me as more promising than Occam's razor. I am interested in pursuing this line of thought as a means of selecting not only ideas perceived to be correct, but also universes.
Anthropic compatibility has traditionally been the criterion to select observed universes. It does not appear feasible to apply this analogously to ideas, though. But perhaps white rabbits are naturally disfavored in this scheme? Higgo James wrote: > It seems to me that a good way of selecting one idea over is [sic] competition is > Occam's razor >
