That said, I do think there’s enough evidence that I would bet (not at extreme odds) that it is bad for productivity to have organizational cultures that emphasize working very long hours (say > 60 hours / week), unless you are putting in special care to hire people compatible with that culture. Partly this is because I expect organizations to often be unable to overcome weak priors even when faced with blatant evidence.
I think the evidence is roughly at “this should be a weakly held prior easily overturned by personal experience”: https://www.lesswrong.com/posts/c8EeJtqnsKyXdLtc5/how-long-can-people-usefully-work
