I worked at a place that prided itself on being "data driven". They put it on tshirts and made fun of startups they said were driven by emotions and gut feelings.
Someone brought up four day workweeks. They said every study they'd seen showed it was better for everyone involved.
The ceo, one of the big "data > feelings" guys, just laughed and said "we're not doing that.". Didn't look at any data or studies. Just shut it down.
So I'm glad there's another study about this, but I don't know how to get through to the thin skinned leaders.
