In 1971, Herbert A. Simon — a future Nobel laureate — warned that a world flooded with information creates a poverty of attention. That line wasn’t a metaphor. It was a business model blueprint. Read it in his collected essays via Archive.org.

Platforms are not neutral broadcasters. They are optimisation engines. Their primary success metric is retention: watch time, session length, return frequency. This is publicly described in platform-adjacent research and the broader “engagement ranking” paradigm, and was echoed repeatedly throughout reporting on Meta’s internal documents in The Wall Street Journal’s Facebook Files.

Your feed is an environment shaped by prediction: what you’ll click, what you’ll watch, what you’ll argue with. That loop is a form of selective exposure — repeatedly reinforcing themes that match identity and emotion.

This is why two people can live in the same city and experience two entirely different “realities.” Not because truth changed — because the filters did.

Behavioural psychology mapped this decades ago. Variable reward schedules increase repeated behaviour — even when the reward is minor. That lineage runs through B.F. Skinner’s operant conditioning work (see overview via Encyclopaedia Britannica).

Every refresh is uncertainty. Uncertainty is fuel. The brain learns to chase the next hit — outrage, validation, novelty, arousal — and the system learns exactly which flavour keeps you engaged.

Research has repeatedly shown that emotionally charged information spreads faster than neutral information. One landmark paper in Science examined diffusion dynamics on social networks and found that falsehood spreads differently — and often faster — than truth (paper: Vosoughi, Roy, & Aral (2018)).

This doesn’t require a censor. It requires a scoreboard. If outrage wins the scoreboard, outrage becomes the culture. If novelty wins, novelty becomes “news.” If identity conflict wins, society becomes a permanent argument.

“A wealth of information creates a poverty of attention.”

Large bodies of literature link heavy social media exposure with mental health outcomes — especially in adolescents. For a clean, citable overview in a medical journal context, see discussions and reviews in JAMA Pediatrics (search within the journal for “social media” + “mental health” if you want multiple studies, not one cherry-picked stat).

The practical consequence is brutal: when attention is constantly fragmented, people become easier to steer — not because they’re stupid, but because they’re cognitively exhausted.

This is not self-help fluff. It’s cognitive defence. Add friction. Reduce exposure. Rebuild long-form capacity. Make the system work harder to reach you.

Practical moves that actually change outcomes:
• Kill autoplay, infinite scroll, notifications (remove involuntary triggers).
• Time-box exposure (one window, not constant drip).
• Replace feed consumption with direct sources (you choose the inputs).
• Train depth: long-form reading, writing, and offline thought.
• Build signal: publish, create, teach — don’t just react.
