Tu Quoque Fallacy: Definition & Examples
Tu quoque (Latin for "you too," sometimes called the appeal to hypocrisy or whataboutism) is a logical fallacy that deflects criticism by pointing out that the accuser is guilty of the same thing. Instead of addressing the argument, the person turns it back on the speaker: "But you do it too!"
Tu Quoque (Fallacious)
"You say smoking is bad, but you smoked for years."
The speaker's history doesn't change whether smoking is harmful.
Legitimate Response
"I agree smoking is harmful — here's the evidence."
Addresses the claim on its merits, regardless of who said it.
Why Tu Quoque Is Fallacious
An argument's truth doesn't depend on whether the person making it lives up to their own standard. A doctor who smokes can still give correct medical advice about lung cancer. A speeding driver can still be right that speed limits save lives. Tu quoque deflects attention from the argument to the arguer — making it a specific form of ad hominem.
The fallacy is psychologically powerful because hypocrisy feels intuitively wrong. We expect people to practice what they preach — and when they don't, we feel justified in dismissing their advice. But the feeling of unfairness, however valid emotionally, doesn't make their argument logically wrong.
Tu Quoque Examples

- —"You want me to read more? You spend every evening watching TV."

Tu Quoque vs. Legitimate Hypocrisy Arguments
Not every mention of hypocrisy is a tu quoque fallacy. There are situations where someone's inconsistency is genuinely relevant:
- —Credibility of testimony: If someone claims a diet works because it worked for them, but they didn't actually follow it, their personal experience is no longer evidence.
- —Sincerity of advocacy: If a politician campaigns on fiscal responsibility while spending lavishly, the inconsistency is relevant to their character and trustworthiness — even if their policy argument might still be correct.
- —Moral authority: In ethical debates, whether someone lives their values can be relevant to the discussion — though it still doesn't determine whether the moral claim itself is true or false.
The key distinction: pointing out hypocrisy becomes fallacious when it's used to dismiss the argument rather than to question the person's sincerity. "You're a hypocrite, so your argument is wrong" is tu quoque. "You're a hypocrite, which makes me doubt your commitment" is a different (and potentially valid) point.
Using Tu Quoque in Your Writing
Tu quoque is one of the most natural-sounding fallacies in dialogue. Real people use it constantly — in families, in politics, in courtrooms. Giving a character a "but you do it too" response is an instant way to create realistic conflict, reveal defensiveness, or show that a conversation is going off the rails. It's also a powerful tool for dramatic irony: the audience can see the deflection even when the characters can't.
