The certainty effect is a concept from behavioral economics and decision theory, particularly associated with Prospect Theory, formulated by Daniel Kahneman and Amos Tversky. It refers to the tendency for individuals to overvalue outcomes that are certain compared to those that are merely probable, even when the expected values of the uncertain outcomes might be higher.
