LW/​OB Rationality Quotes, June 2011

I saw this article and thought “ah, that’s what’s been missing.” There’s many a bon mot posted here that’s outside the domain of the usual rationality quotes thread. Overcoming Bias seems still to be excluded from those too, even if the two blogs have diverged.

So:

This is a thread for posting any interesting rationality-related quotes you’ve seen on LW/​OB.

  • Please post all quotes separately (so that they can be voted up/​down separately) unless they are strongly related/​ordered.

  • Do not quote yourself.

  • Do not post quotes that are NOT comments/​posts on LW/​OB—there is a separate thread for this.

  • No more than 5 quotes per person per thread, please.

(You may care to check the previous posts for duplicates.)
