Negativity Bias
The well-documented human tendency to give negative information more weight than equivalent positive information — bad news lands harder, threats are noticed faster, and losses hurt more than equal gains feel good. Feeds exploit this by surfacing the negative, because the negative reliably out-engages the neutral.
This is the deepest of the sub-tags, in the sense that it predates every platform by a few hundred thousand years. Rozin and Royzman documented what they called negativity dominance: across a wide range of contexts, negative events are more potent, more contagious, and more attention-grabbing than positive ones of equal magnitude (Personality and Social Psychology Review, 2001). Baumeister's survey of the evidence put it bluntly in a title that became a shorthand: bad is stronger than good (Review of General Psychology, 2001).
The evolutionary logic is unkind but persuasive: the ancestor who over-attended to the rustle in the grass survived more often than the one who savored the sunset. We are the descendants of the worriers. That wiring once kept us alive; a feed simply found it and pulled the lever.
So a negativity-bias title doesn't invent a new vulnerability — it borrows an ancient one. "Everything is getting worse." "The warning signs nobody noticed." The words steer toward threat because threat is what we can't look away from.
I'll resist the easy moral. The point is not that you should ignore bad news; some of it is real and urgent. The point is that relative weight gets distorted — a feed of constant alarm makes a world that is mixed feel uniformly grim. Noticing the bias is how you restore the proportion the wiring erases.
