Overstimulation Is Ruining Your Life! - 12 Ways To Take Back Control Of Your FOCUS | Johann Hari

He describes a “global attention crisis” with multiple proven drivers—technology being only one—and argues the solution must be multi-layered, not reduced to blaming individuals or a single device.

He argues social media’s surveillance-and-advertising model rewards maximizing time-on-app, so platforms are engineered to keep users scrolling rather than helping them do what they say they want (like meeting friends).

He says algorithms optimize for engagement, and because people stare longer at upsetting content (negativity bias), platforms end up privileging anger—fueling polarization—and anger then further impairs attention.

Citing Professor Earl Miller, he says humans can only consciously think about one thing at a time; what feels like multitasking is rapid task-switching with measurable costs (errors, memory loss, lower creativity, reduced “mental bandwidth”).

He describes experiencing both withdrawal-like cravings and then a rapid return of deep reading, better sleep, and increased creativity when he removed constant digital interruptions; he later frames mind-wandering as a vital form of attention.
