Rationality Quotes from people associated with LessWrong

The other ra­tio­nal­ity quotes thread op­er­ates un­der the rule:

Do not quote from Less Wrong it­self, Over­com­ing Bias, or HPMoR.

Lately it seems that ev­ery MIRI or CFAR em­ployee is ex­cempt from be­ing quoted.

As there are still in­ter­est­ing quotes that hap­pen on LessWrong, Over­com­ing Bias, HPMoR and MIRI/​CFAR em­ployee in gen­eral, I think it makes sense to open this thread to provide a place for those quotes.
