It's a very well controlled study about... what the study claims to do. Yes, they didn't study a different thing, for _many_ reasons. Yes, we shouldn't haphazardly extrapolate to other parts of Engineering. But it looks like it's a good study nonetheless. There are some very good findings though, like how the devs thought they were sped up but they were actually slowed down.
