A New Study Spells Bad News for Cellphone Bans
The latest study of cellphone bans caused shockwaves as it appeared to be really bad news for advocates of the bans. This study basically compared a specific type of ban, lockable pouches (such as Yondr pouches) with schools that did not use them. Across the board this was basically a null study…no benefits to standardized testing scores, classroom attention, bullying, and the mental health outcomes were “statistically significant”, though wobbling in both directions, and so close to zero in effect size to be more likely due to methodological noise than “real” effects (which would also explain the wobble)1.
