Another monthly installment of the rationality quotes thread. The usual rules apply:
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Do not quote yourself.
Do not quote comments or posts from Less Wrong itself or from Overcoming Bias.
No more than 5 quotes per person per monthly thread, please.
See also this Will_Newsome comment. (I incorrectly remembered that it said something like “If all your friends jumped off a bridge, would you jump too?” “If all of them survived, I probably would.”)
