How Bad Information Becomes Common Knowledge
Anyone who reads the news, shares articles, or tries to figure out what's true - which is everyone. Particularly useful for students, journalists, and anyone who's ever shared something online and later wondered if it was accurate.
Most misinformation doesn’t arrive wearing a sign. It doesn’t look obviously wrong, or shady, or suspicious. It looks like an article you’d share. A statistic you’d quote. A claim your colleague mentioned over coffee, prefaced with “apparently…”
This collection traces the lifecycle of a bad piece of information - from the moment someone first cites a dodgy source as though it’s authoritative, through the process of repetition and re-citation that makes it look established, to the deliberate tactics that accelerate the whole thing. It’s the story of how something untrue becomes something everyone just knows.
We start with the original sin: treating an unreliable source as though it’s credible. Then we look at why our brains are wired to go along with it. Then we follow the claim as it spreads - organically through the Woozle Effect, and deliberately through source laundering. By the end, you’ll have a clear picture of the chain, and you’ll know where to break it.
This isn’t about becoming a cynic who trusts nothing. It’s about becoming someone who knows which questions to ask - and when to ask them.
The journey
- 1 Logical Fallacy Appeal to False Authority Using a source that sounds authoritative but isn't actually reliable or relevant as the foundation of an argument.
- 2 Cognitive Bias Authority Bias We give disproportionate weight to the opinions of people we perceive as authorities - even outside their expertise.
- 3 Psychological Phenomenon Woozle Effect When a weak or unsupported claim gets cited and re-cited until it starts looking like established fact.
- 4 Psychological Phenomenon Illusory Truth Effect The more often we hear something, the more likely we are to believe it - regardless of whether it's true.
- 5 Manipulation Tactic Source Laundering Passing unreliable information through credible-looking channels until it appears legitimate.
- 6 Cognitive Bias Confirmation Bias We seek out information that supports what we already believe, and ignore what doesn't.
- 7 Manipulation Tactic Firehose of Falsehood Flooding the information space with so many lies, half-truths, and contradictions that people give up trying to figure out what's true.
