Fallacy Fallacy (Argumentum ad Logicam)

The formal meta-fallacy of concluding that a proposition is false simply because the argument presented for it contains a logical fallacy. This is a critical thinking fail state: you correctly spot flawed reasoning (e.g., an appeal to emotion, a post hoc correlation) but then incorrectly assume the conclusion is therefore untrue. A bad argument for a claim doesn't automatically make the claim wrong; it just means you're still waiting for a good argument.

Fallacy Fallacy (Argumentum ad Logicam) Example: "He argues we should help the poor because it makes us feel good. That's just an appeal to emotion, a fallacy. Therefore, we should not help the poor." This commits the Fallacy Fallacy. The poor might still desperately need help; the speaker has just shot down one weak justification, not disproven the need for the action itself.
