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- Do not quote yourself.
- Do not quote from Less Wrong itself, Overcoming Bias, or HPMoR.
- No more than 5 quotes per person per monthly thread, please.
When I need this I just look at the nearest object. If the first letter is between a and m, that's a 0. If it's between n and z, that's a 1. For larger strings of random bits, take a piece of memorized text (like a song you like) and do this with the first letter of each word.
[Aside] When do you need to generate random numbers in your head? I can think of literally no time when I've needed to.
