I think it is harmful for it to be entertained, if it does not deserve to rise to the level of attention.

Well, now you've worried me. Could you explain why? I'll certainly retract my comment if this is true.

It is dangerous in the same way as bringing John Q. Snodgrass to trial for murder. We might overweight evidence in favor of the hypothesis. Once something has been raised to the level of attention, it is hard for humans to demote it again.

I...really? That's shocking. Are you really telling me that people on LW believe it's wrong to suspend judgement on a proposition? I really don't think that can be true.

Any proposition worth talking about, is worth judging. If the evidence and your priors yield a 60% probability that the sky is blue and a 39% probability that the sky is green, then that is exactly to what extent you should think those propositions are true. Note you do not find many religious agnostics here, as compared to atheists, often for the same reason.

Human intuition is a valuable heuristic. As a mathematician I constantly entertain hypotheses I don't believe to be true, for the simple reason that my intuition presented them to be considered. I don't believe I would be at all effective otherwise (although I did just now entertain the hypothesis, despite my lack of belief!)
