A logical fallacy where one dismisses an argument by attacking the opponent'
s intelligence, typically with variations of "you're stupid." The fallacy lies in treating IQ as a proxy for correctness, as if being less intelligent automatically makes someone
wrong about a particular claim. "You're too dumb to understand" becomes a way of avoiding engagement, a preemptive dismissal that requires no
evidence and addresses no substance. This fallacy is the
lazy debater's favorite: rather than explain why a position is wrong, simply assert that only stupid
people would hold it, thereby positioning oneself as intelligent without demonstrating any actual intelligence through reasoned argument.
Example: "He couldn't explain why her economic analysis was flawed, so he just called her stupid. Argumentum
Ad Intelligentiam: when you can't
win the argument,
attack the arguer's IQ."
