Hm, I may have to see if I can track down Humphrey’s original data (DfSE did not have a direct citation).
Possibly Humphrey was wrong.
Two other possibilities I can think of are that Humphrey’s data was of a different sample of people (I would imagine that 20 years old could possibly mange more productive time per week for longer than say a sample that included 20 to 60 year olds.)
Another might be that startups long weeks include a mixture of technical work and “team bonding” and other non-technical work that is beneficial, but less exhausting 40+ hours of technical work.
