The Evidence
The numbers don't lie.
Not a moral panic. Not opinion. Six data series — compulsive checking, always-on connectivity, lost sleep, lost face-to-face time, felt addiction, and clinical harm — tracked over years by Pew, the CDC, and independent researchers. Together they trace a single story: cause, behaviour, direct harm, outcome.
