One of the most baffling mysteries of our time for me is the fact that this truth (more working hours = less productivity) is still being massively denied and the non-existent and strawman "arguments" against it have been beaten to death and debunked thousands of times... yet never fail to reappear in any discussion on the topic. It seems the economic pressure for supporting this bullshit story is still too strong. S…
Maybe it's because there's a lot of confusion created by people who claim that there's an inverse correlation between hours worked and overall productivity, instead of hours worked and marginal productivity. I have no trouble believing that (on average) someone who works 50 hours doesn't accomplish 25% more than someone who works 40 hours. I find it almost impossible to believe that they don't accomplish more overall…
Currently leading a team I see different behavior from team members working longer hours. For example, we had a conversion to do that was running into a deadline. Together with a team of 4 we worked into the evenings to get it done. 2 of them 'compensated' by being there but browsing more Reddit, the other 2 actually sat down and got the work done.
I see a lot of comments justifying the first kind of behavior, and it doesn't make sense to me. If you are not productive because you are on HN, you're doing that to yourself. At 40-60h we're in the realm of that being a choice, and then you're choosing not to be productive.
FWIW, I'm not trying to justify people working long just to show that they are there/committed. That's a terrible practice too.
