Another month has passed and here is a new rationality quotes thread. The usual rules are:

Please post all quotes separately, so that they can be upvoted or downvoted separately. (If they are strongly related, reply to your own comments. If strongly ordered, then go ahead and post them together.)
Do not quote yourself.
Do not quote from Less Wrong itself, HPMoR, Eliezer Yudkowsky, or Robin Hanson. If you'd like to revive an old quote from one of those sources, please do so here.
No more than 5 quotes per person per monthly thread, please.

Well, yeah, if an authority says that the Hubble constant is 68 km/s/Mpc and you interpret that in such a way that if the Hubble constant is 67 km/s/Mpc or 69 km/s/Mpc the authority is wrong, then you'd better assume the authority is wrong -- though that's not a very informative assumption and anyway in the real world authorities often make claims more vague (i.e. whose negation is less vague) than that.
