The Misinformation Toolkit
Teachers and students aged 16+, and anyone who wants to understand how misinformation works
We live in an age where information is abundant and trust is scarce. Every day, we’re exposed to claims, framings, and narratives designed not to inform us but to move us - to make us angry, afraid, or certain about things we haven’t actually examined.
This collection is a guided tour through the psychological machinery that makes misinformation work. It starts with the biases that make us vulnerable - the mental shortcuts our brains take that bad actors know how to exploit. It moves through the tactics that are deliberately used to confuse, overwhelm, and exhaust us. And it ends with the psychological effects that emerge when all of this operates at scale - the quiet, structural damage that happens when an entire society loses its ability to agree on what’s true.
This isn’t about being smarter than everyone else. It’s about knowing the tricks well enough to notice when they’re being played - on you, and on the people around you.
Read these in order. Each concept builds on the last.
The journey
- 1 Cognitive Bias Confirmation Bias We seek out information that supports what we already believe, and ignore what doesn't.
- 2 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.
- 3 Cognitive Bias Availability Heuristic We judge how likely something is based on how easily an example comes to mind.
- 4 Rhetorical Device Framing Effect The way information is presented changes how we respond to it - even when the underlying facts are identical.
- 5 Cognitive Bias Anchoring Bias The first number or piece of information we hear disproportionately shapes everything that follows.
- 6 Cognitive Bias Bandwagon Effect We're more likely to believe or do something if lots of other people already do.
- 7 Cognitive Bias Authority Bias We give disproportionate weight to the opinions of people we perceive as authorities - even outside their expertise.
- 8 Cognitive Bias Affect Heuristic We make judgements based on our current emotions rather than objective analysis.
- 9 Logical Fallacy False Equivalence Treating two things as equally valid or important when they clearly aren't.
- 10 Manipulation Tactic Gish Gallop Overwhelming someone with a flood of arguments, regardless of their accuracy, so they can't possibly respond to them all.
- 11 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.
- 12 Manipulation Tactic Sealioning Endlessly demanding evidence or explanations in bad faith, disguised as polite curiosity.
- 13 Manipulation Tactic Whataboutism Deflecting criticism by pointing to someone else's wrongdoing instead of addressing the original point.
- 14 Manipulation Tactic Motte-and-Bailey Holding a controversial position but retreating to a much more defensible one when challenged - then switching back once the pressure's off.
- 15 Psychological Defence Motivated Reasoning Using our intelligence not to find truth but to defend conclusions we've already reached.
- 16 Psychological Phenomenon Backfire Effect Correcting someone's false belief can actually make them believe it more strongly.
- 17 Psychological Phenomenon Pluralistic Ignorance When most people in a group privately disagree with a norm but go along with it because they assume everyone else agrees.
- 18 Psychological Phenomenon Learned Helplessness When repeated failure or lack of control teaches us to stop trying - even when things change.
