I've soured on these sorts of behavioral study generally. They're so rife with statistical problems and publication bias that I think they pretty much amount to throwing darts at the truth, and as a result, whatever opinion you happen to hold about the right way to do $X, you can find a "study" to back you up. For or against pair programming? For or against open offices? For or against Agile? Oh boy, the literature has a study for you! (Or, if you're into nutrition, you can find studies for and against keto! Or for and against eggs! :Eyeroll:)

This kind of nonsense is what I like to call anti-knowledge. It tangles our decision making and it'd be better if it didn't exist at all.
