Denying the Antecedent (also known as: inverse error, inverse fallacy) Description: It is a fallacy in formal logic where in a standard if/then premise, the antecedent (what comes after the “if”) is made not true, then it is concluded that the consequent (what comes after the “then”) is not true. Logical Form: If P, then Q. Not P. Therefore, not Q. Example #1: If it barks, it is a dog. It doesn’t bark. Therefore, it’s not a dog.
