Fun Fact
“Fallacious” comes from the Latin fallacia, meaning “deception” or “trickery.” The term is closely linked to logical fallacies—errors in reasoning that often appear persuasive but are fundamentally flawed. Common examples include the slippery slope fallacy and ad hominem attacks. Recognizing fallacious reasoning is a key skill in debate, critical thinking, and media literacy, helping people avoid being misled by faulty logic.
