§ 01 · The Library
A taxonomy of bad thinking.
Thirty-plus patterns show up again and again — in political speech, marketing, group chats, and your own reasoning. Learn to name them and they lose their power.
01◆ Relevance
Ad Hominem
Attacking the person making the argument rather than the argument itself.
“You can’t trust his economic plan — he cheats at golf.”
02◆ MisrepresentationStraw Man
Misrepresenting someone’s argument to make it easier to attack.
“You want safer streets? So you want a police state.”
03◆ StructureFalse Dilemma
Framing a complex issue as a choice between only two options.
“You’re either with us, or you’re against us.”
04◆ RelevanceAppeal to Authority
Claiming something is true because an authority figure says so.
“A celebrity doctor said it, so it must work.”
05◆ CausationSlippery Slope
Arguing a small step inevitably leads to an extreme outcome.
“If we allow this, next it’ll be chaos.”
06◆ StructureCircular Reasoning
Using the conclusion as a premise, in slightly different words.
“The book is true because the book says it’s true.”
07◆ EvidenceHasty Generalization
Drawing a broad conclusion from a small or biased sample.
“I met two rude locals. The whole city is rude.”
08◆ RelevanceRed Herring
Introducing an irrelevant topic to divert attention from the real issue.
“Why worry about pollution when crime exists?”

§ 02 · How it worksPractice,
Practice,
not lectures.
Reading a list of fallacies won’t change how you think. Spotting them — in live video, under pressure, one round at a time — will.
01STEP
Watch a real clip
The app feeds you actual reels, speeches, and headlines — the arguments you'd scroll past otherwise.
02STEP
Spot the fallacy
As soon as the move is made, you tag it. Fast, under pressure, with instant feedback on why it fails.
03STEP
Learn on the miss
Every wrong answer gets explained. Every right one builds a streak. Your weak spots surface automatically.
04STEP
Carry it into life
After a week, you start hearing fallacies in the wild — in the news, at work, in your own first drafts.

§ 03 · Cognitive biases
The bugs in your own reasoning.
Fallacies are other people’s sloppy arguments. Biases are the ones running silently in your own head. Learn the shapes — and you start catching yourself.
