Ultimately, the authors of the study conclude: "[Our] results suggest that in-class phone bans represent a low-cost, effective policy to modestly improve academic outcomes, especially for vulnerable student groups, while enhancing student receptivity to digital policy interventions."
It is interesting whether this conclusion really requires much quantitative evidence. Is it true if the effect is 0.01 SDs? Maybe so, not sure. I guess this gets at what study design here would be sufficient for policy choice.
Good point. I find this tidbit fascinating. bsky.app/profile/john...
