An information paradox is a paradox about information. Such paradoxes include:
- Arrow's information paradox — the difficulty of selling information when describing the nature of the information to the buyer would, in itself, communicate the essential information.
- Black hole information paradox — information may be lost when a black hole evaporates but this would violate the principles of quantum mechanics.
