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- Do not quote yourself.
- Do not quote comments or posts from Less Wrong itself or from Overcoming Bias.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.
Karl Popper
There's a failure mode associated to this attitude worth watching out for, which is assuming that people who disagree with you are being irrational and so not bothering to check if you have arguments against what they say.
