Denying the antecedent is a logical fallacy that occurs when, from a conditional statement, one incorrectly infers that if the antecedent (the "if" part) is false, then the consequent (the "then" part) must also be false. This form of reasoning is flawed because the consequent can still be true even if the antecedent is false. Everyday example: Someone said "If I study hard, I will pass the exam. I didn't study hard, so I will not pass the exam." This reasoning is fallacious because there are other ways to pass the exam besides studying hard, such as already knowing the material or making educated guesses. The absence of studying doesn't necessarily guarantee a failure; it just negates one specific path to success. This example demonstrates the error in concluding that the failure of the condition (studying hard) automatically leads to the failure of the outcome (passing the exam).
