>The fact they already tried 5 days a week and it apparently didn't work.
How didn't it work? Probably the devie you're typing this on was made by a person working 5 days/week, or way more if we're talking early iOS /Android devices.
I am speaking in the context of your own assumption in your post, that previously people were only doing 4 days of work in a 5 day week, so there's some option of getting people to work 5 days a week at the 4-day-a-week pace. Please don't equivocate on your own terminology for the purpose of hostilely misunderstanding my reply.
If you're going to roll with "actually people have in fact been productively working 5 days a week after all" than I would advise FirmwareBurner of 6 minutes ago to take the debate up with FirmwareBurner of 1 hour ago. I don't see that I'd add any value in mediating that discussion.
I'll pile on since I find your "sudden" confusion on this comment chain to be a disgusting and shameful way to try and engage conversations with other people.
The top post tries to identify the results as reducing the hours of 5 days of work into 4, the response to that was highlighting that the goal wasn't to make up for missing hours but to try and measure the efficacy of needing that fifth day's 'worth' of hours. You then selectively choose how you interprete the topic to be either:
1) questioning why they couldn't use their results of 5 days VS 4 days to effectively say "if you're effective in 4, then why not 5?
then when questioned on how this doesn't make sense in the context of the article, feign confusion on the distinction and ignore the results of the article to flip flop to your other point:
2) questioning the articles results by asking others outside of the study to personally prove to you what the measure of "success" is since you see modern technology built with this framework (phones) as a reason why it shouldn't change
despite this being a nonsequitor that isn't a point anyone has shown interest in discussing. Then when asked why you went from being confused on why they couldn't use the results showing their effectiveness to try and enforce another "effective" day, to then denying the results and saying that it's already effective and to ask others to personally prove to you why it isn't effective (instead of reading the article).
