Tu quoque (/tˈkwkw/;[1] Latin for "you, too" or "you, also") or the appeal to hypocrisy is an informal logical fallacy that intends to discredit the opponent's position by asserting the opponent's failure to act consistently in accordance with that position. It attempts to show that a criticism or objection applies equally to the person making it. This attempts to dismiss opponent's position based on criticism of the opponent's inconsistency and not the position presented.[2] It is a special case of ad hominem fallacy, which is a category of fallacies in which a claim or argument is rejected on the basis of fact about the person presenting or supporting the claim or argument.[3] To clarify, although the person being attacked might indeed be acting inconsistently or hypocritically, such behavior does not invalidate the position presented.
