I have some gripes with this group and their publications:<p>- They don't randomize pilots, so any effect you see is likely to be confounded<p>- In this publication, it appears there was ~50% attrition between the initial pilot and the follow-up study — again, a huge source of potential confounding<p>- As another example, in another publication, they showed a plot of GDP per capita against average working hours, and insinuated from the negative relationship that less working hours somehow made workers (causally) more productive, without even hinting at the obvious alternative explanation that people work less as they get more productive because they don't have to work as much to maintain standard of living.<p>I like that things like this are being tried, but I wish the research conducted on it were more intellectually honest and less obviously geared towards pursuing an agenda. The level of analysis here is more like a company marketing whitepaper than anything bordering on scientific.<p>Don't get me wrong, personally I think companies where it's feasible should just define minimum presence where the business needs it and leave it to employees where and when to do the work within those constraints depending on preferences and their situation. I don't have an axe to grind against working less (and in my circles it seems like many people are making this decision by reducing their workload to e.g. 80%, albeit at a corresponding salary cut). But the whole thing just seems a big disingenuous.
