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.
Famous quotes containing the words information and/or paradox:

Simpson case and would like to offer your services, press 3 now. If you would like the address where you can send a letter of support to O.J. Simpson, press 1 now. If you are seeking legal representation from the law offices of Robert L. Shapiro, press 4 now.”
