The Allais Paradox demonstrates a violation of another one of expected utility theory’s core assumptions, known as the independence axiom, which states that adding an independent outcome to decision options should not change decision preferences. The Von Neumann-Morgenstern expected utility axioms formalize a model of rational behavior. But why do people weigh probabilities?
