Why feeds leave you worse off
Social and video feeds are ranked by engagement, and nothing engages like strong emotion — outrage, envy, anxiety. The feed isn't malfunctioning when it makes you feel worse; it's working as designed. And because it's infinite, there's no built-in moment where you're "done" and put the phone down satisfied.
The fix isn't usually willpower. It's swapping the destination: keep the pick-up-the-phone reflex, but point it at something finite and genuinely pleasant, so the same habit ends after two minutes instead of twenty.
