Two things stack. The delivery is a variable-ratio schedule, the most resistant pattern there is to walking away from. The content on top is selected for what holds attention, and what holds attention is anger and threat: people react measurably harder to negative news than positive across 17 countries ¹, false news spreads about six times faster than true ², and outrage language travels furthest ³. Every scroll is also a sample of strangers' best moments; a few minutes of it drops how you rate yourself ⁴.

Cutting back is where the clean evidence is. About 2,700 people paid to quit Facebook for four weeks got roughly an hour a day back, reported better wellbeing, and were still using it less months later ⁵. Capping Instagram, Facebook, and Snapchat at ten minutes each per day cut loneliness and depression in three weeks ⁶. When Facebook rolled out campus by campus in near-random order, severe depression rose about 7% and anxiety about 20% once it arrived ⁷. Screen reading at night also halves your melatonin and shoves your body clock about ninety minutes later ⁸.

Reduce the quantity; don't curate the content. The friction has to live in the environment, because the schedule is exactly what willpower loses to.

The arc, roughly.

• Week one: the morning is yours again, and people across the table notice you're actually there.
• Month one: mood steadies and the background hum of distant anger fades; the deactivation trial caught this on a wellbeing composite in four weeks ⁵. Sleep gets easier.
• A season in: focus returns. You finish a book again, and stop paying the roughly twenty-minute recovery tax on every interruption ⁹.
• A year in: a two-week-break study still measured life-satisfaction gains six months later ¹⁰.
