Does Hypocrisy Cancel the Truth of a Criticism?

When someone who is regularly late criticises a colleague for being unpunctual, the natural reply is, ‘What about you?’ That reply identifies hypocrisy, but it does not answer whether lateness damages cooperation. Treating the critic’s similar conduct as proof that the argument must be false is usually a tu quoque: ‘you do it too’ replaces an assessment of the claim itself.

Yet the critic’s conduct is not entirely irrelevant. Contemporary discussions of the ‘standing to blame’ suggest that someone who applies one standard to others and another to themselves may lose the standing to demand accountability in a condemnatory voice. The issue is not only logical truth, but whether both people are being treated as moral equals. The late colleague can correctly say that punctuality matters while lacking the right to speak from a superior position.

Three questions should be separated: is the criticism true, does this person have the standing to blame in this way, and is the expression likely to support improvement? The first depends on reasons and facts. The other two are affected by hypocrisy, motive and the history of the relationship. Acknowledging one’s own similar fault and accepting the same standard can help restore legitimate standing, but it does not replace an argument.

My view is that ‘you do it too’ should be neither a universal shield nor dismissed as automatically irrelevant. It cannot overturn a true claim, but it may expose inequality in the relationship of blame. A mature response asks both: is the criticism right, and what entitles this person to deliver it in this way? Both matter, but they are not the same question.
