Cognitive dissonancevsHypocrisy

The short answer

Hypocrisy is claiming a virtue or belief you do not actually hold — a charge about you, whether or not anyone is watching. Dissonance is the clash between your own cognitions, and the private discomfort that clash produces — and the difference matters, because dissonance is a normal mental state everyone experiences, not an accusation.

Where the confusion comes from

Cognitive dissonance is the same as hypocrisy.

In Festinger's original formulation dissonance IS the clash between cognitions, and the discomfort is what it produces; in everyday usage the word often names the discomfort itself. Either way it carries no moral judgement. It's a normal, universal state — not a character flaw.
