Spotting common logical fallacies

What you’ll practice

This quiz trains you to recognize common logical fallacies in everyday statements, headlines, and debates, not just memorize definitions.

Every question uses a 4-option multiple-choice format with no timer, so you can slow down, reread the claim, and focus on the reasoning.

Difficulty and quiz setup

Difficulty is mixed: you’ll see straightforward classics (like ad hominem) alongside trickier look-alikes where wording hides the error. You can choose how many questions to answer per session and adjust difficulty to keep practice manageable or more challenging.

Common pitfalls to avoid

Many mistakes come from matching keywords instead of checking the argument’s structure—what is being concluded, and what evidence is actually offered?

• Confusing correlation/causation with post hoc reasoning
• Mixing up straw man with “disagreeing strongly” rather than misrepresenting a claim
• Treating appeal to authority as always wrong instead of judging relevance and expertise
• Missing false dilemmas when extra options are implied but not stated
• Labeling emotional language as a fallacy even when evidence is still provided

Tips to improve quickly

Before choosing an option, restate the argument in your own words and identify the premise-to-conclusion jump; the fallacy usually sits in that gap.
