Entry 034, How lies spread

Algorithms that reward outrage

Also known as: Engagement optimisation, The outrage machine, Ranking for reactions, Doomscroll feed

Engagement-ranked feeds show you more of whatever gets reactions, and nothing gets reactions like anger, so the angriest posts win by design, not by conspiracy.

Sneaky: fools careful people too

Spot it

  • The posts you see most are the ones that make you feel something strong, rarely the ones that inform you.
  • A calm, accurate post from an account gets a fraction of the reach of its angriest one.
  • The feed shows you the other side's worst people, never its reasonable ones.
  • Creators you follow have gradually become angrier, and their numbers have gone up.

How it works

Your feed is not a list. It is a ranking, and the ranking has one job: keep you here. The cheapest signal of “this keeps people here” is reactions (likes, comments, shares, time spent staring), so the feed learns to show you more of whatever gets them. Nobody at the company has to decide that outrage wins. It wins on its own, because anger is the emotion most likely to make a thumb move.

The research is consistent. Brady and colleagues analysed over half a million tweets in 2017 and found that every moral-emotional word in a post (“disgusting”, “shameful”, “evil”) raised its spread by roughly 20 per cent, mostly inside the poster’s own camp. Rathje, Van Bavel and van der Linden found in 2021 that posts about the political out-group were shared about twice as often as posts about one’s own side: attacking “them” is the most reliable growth strategy on the market. Creators notice; so do parties. Over time the calm ones get louder or get quiet. See rage bait.

Then there is the one case where the dial was visible. Internal documents reported by the Wall Street Journal and the Washington Post in 2021 (the Facebook Files) showed that from 2017 Facebook’s ranking counted an “angry” reaction as five times a like. The company’s own researchers later found that posts collecting angry reactions were disproportionately likely to contain misinformation and low-quality news; the weight was cut in stages and set to zero in 2020. A 2018 change meant to promote “meaningful interactions” had a similar effect: publishers and parties in Europe told Facebook they had turned more negative because that was what the new feed rewarded.

Not a conspiracy. An incentive, and incentives are harder to fix than villains.

Example

Same town, same day, same hospital story.

@cityhall_notes, 6h Clarification on the hospital: the ward is moving, not closing. 14 beds go to the new building in March. Full plan in the link. 12 reactions · 3 comments

@wake_up_people_now, 5h They are CLOSING the children’s ward and nobody in the media will say it. This is what they think of your kids. Share before it disappears. 4.1K reactions · 870 comments

The first post is accurate and boring. The second is wrong and electric, and it is the one your cousin saw, because the feed is a scoreboard, not a newspaper. Note the pronoun: they. Posts about an enemy travel furthest.

Why it works on you

  • Anger is a reflex, not a decision. The seconds between seeing a post and reacting to it are exactly the seconds the ranking is built to exploit. See emotional hijacking.
  • The feed looks like reality. It is a sample, selected for reaction. If your timeline suggests the other side is entirely made of maniacs, that is partly because the feed found you their maniacs and hid their accountants. See us vs. them.
  • Everyone else is adapting too. Journalists, politicians and your funniest friend all get the same signal: calm does not travel. The tone of public life drifts without anyone choosing it.

What to do

When the feed is working on you: if a post makes you furious, that is information about the ranking before it is information about the world. Open the source, not the comments, and ask whether a boring version of the story exists.

When you catch yourself feeding it: every angry comment is a vote for more of the same, for you and for everyone who follows you. Save the fury for a friend, and spend a like on a boring, accurate post now and then. That is the one lever you hold.

Change the settings: most platforms now let you switch to a chronological or “following” feed, mute words and hide suggested posts; in the EU, the Digital Services Act obliges the largest platforms to offer a feed not based on profiling. Try it for a week. The world gets quieter.

In a comment section: when someone posts the enraging version, add the boring one with a link. Do not call anyone stupid; the feed showed them this on purpose. Link this page so the next reader knows why.

Don’t confuse it with

  • Censorship or “shadow-banning”. The ranking is not hiding your post because of its politics; it is hiding it because it was calm. Boring the algorithm is not the same as being silenced.
  • Important news that happens to be upsetting. Real scandals also travel fast. The test is whether the anger survives reading the original source.

Reply kit

Calm, copy-pasteable replies for when you meet this under a post. Link the technique, not the accusation.

  • Worth remembering that we're seeing this because it got reactions, not because it's typical or true. The feed ranks for outrage: https://manipedia.eu/en/outrage-algorithms

  • Not saying this is fake, just that calm posts don't travel and furious ones do, so our feeds are a very biased sample. Explainer: https://manipedia.eu/en/outrage-algorithms

  • If your timeline feels like everyone has lost their minds: switch to the chronological feed for a week and see. Why it works this way: https://manipedia.eu/en/outrage-algorithms

We know not every reply sounds natural as a comment, so feel free to put it in your own words. They are here to help, above all older friends and relatives, who often know these tricks less well and so are frequent targets. Reaching them is one of this site’s most important goals.
