💡 Key Idea
A Fallacy Is a Broken Step in Reasoning
Bad logic can still sound convincing.
A logical fallacy is an error in reasoning that makes an argument look stronger than it really is. The conclusion may even be true — but the *reasoning* used to get there is flawed.
↳ A true conclusion reached through faulty reasoning is still a fallacious argument.
📖 Definition
Formal vs Informal Fallacies
Two families of bad reasoning.
Formal fallacies break the rules of logic itself; informal fallacies persuade through tricks of language, emotion, or relevance.
↳ Formal = wrong shape. Informal = wrong substance or tactic.
⚖️ Comparison
Valid vs Fallacious Reasoning
Same topic, very different logic.
↳ Ask whether the conclusion actually follows from the premises — not whether it feels right.
✏️ Example
Ad Hominem: Attack the Person, Not the Point
Insult the speaker, dodge the argument.
↳ Who says it is irrelevant; what they say and how they support it is what matters.
✏️ Example
Straw Man: Attack a Weaker Version
Twist their words, then knock them down.
↳ Always restate the opponent's view fairly before responding.
✏️ Example
False Dilemma: Only Two Choices?
Forced into a fake either-or.
↳ Real life rarely fits into two boxes — demand the full set of options.
✏️ Example
Appeal to Authority: Famous ≠ Correct
A celebrity said it, so it's true?
↳ Authority is only as good as the evidence behind the claim.
✏️ Example
Bandwagon: Everyone Does It
Popularity is not proof.
↳ Ask for evidence, not a crowd count.
✏️ Example
Slippery Slope: One Step to Disaster
One small step, a chain of doom.
↳ A chain of 'will lead to' claims needs proof at every link.
✏️ Example
Circular Reasoning: Assuming the Conclusion
The proof is the claim itself.
↳ Real proof must come from outside the claim being defended.
✏️ Example
Post Hoc: Correlation Isn't Cause
After it, therefore because of it?
↳ Sequence in time is not proof of cause.
✏️ Example
Red Herring: Change the Subject
Dodge the question with a distraction.
↳ Notice when the topic quietly shifts — and pull it back.
⚠️ Common Mistake
Spotting a Fallacy ≠ Winning the Argument
Naming a fallacy isn't a rebuttal.
The fallacy fallacy is assuming that because an argument is flawed, its conclusion must be wrong.
↳ Fallacies expose weak reasoning — they don't automatically disprove the conclusion.
⚙️ Process
A 4-Step Fallacy Check
Run every argument through this filter.
↳ A repeatable checklist beats memorizing dozens of fallacy names.
🎯 Exam Tip
Exam Strategy: Name + Explain + Fix
Three moves earn full marks.
Examiners reward precise identification plus reasoning — not just the label.
↳ Label + reason + correction = full-marks answer.
🧠 Memory Trick
Remember the Big Five by Their Targets
Five fallacies, five targets.
↳ Grouping fallacies by what they attack makes recall far easier.
🌍 Real World
Fallacies in Ads and Headlines
You're targeted daily.
Recognizing these patterns makes you a harder target for manipulation.
↳ Everyday media is full of fallacies — spotting them is a life skill, not just an exam skill.
