An interactive trainer for clear thinking
Learn to hear the flaw in any argument.
Logical fallacies are everywhere — debates, meetings, comment sections. Fallacy Lab trains you to spot them in the wild, understand why they fail, and never be fooled twice.
“Everyone I know is switching to the new Zephyr phone. It obviously must be the best phone out there.”
Sounds convincing? It's a Bandwagon fallacy. Popularity isn't proof.
