I think that trying to understand the worldview of people who are very different from you is often useful.
Trying to explain ideas in a way that you never explained them before can also be useful.
I agree. I hope I didn't give the impression that I didn't. Usefulness belongs to instrumental rationality more so than to epistemic rationality.

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.
