Fallacy of Perfect Consistency

The logical fallacy of demanding that an opponent be perfectly consistent in everything they say or do—across contexts, over time, in every statement—while exempting oneself or one's own side from any such scrutiny. The fallacy ignores that human beings are complex, that contexts change, that learning involves changing one's mind, and that perfect consistency is impossible for any real person or movement. It's the logic of "you said X five years ago, so you can't say Y now," of "your actions don't perfectly match your words, so your words are invalid." The Fallacy of Perfect Consistency is beloved of those who want to dismiss opponents without engaging their current arguments, who would rather dig up old contradictions than address present claims. The cure is recognizing that consistency is not a binary state but a spectrum, and that growth, learning, and context all produce apparent contradictions that are actually signs of life.

Example: "He found a tweet she'd written ten years ago, before she'd studied the issue, before she'd changed her mind. 'Aha!' he declared. 'Inconsistency! Your current views are invalid!' The Fallacy of Perfect Consistency had done its work: avoiding engagement with her current arguments by appealing to her past self. She'd learned, grown, evolved—but to him, that was weakness, not strength."
