A quantum-conceptual explanation of violations of expected utility in economics

Boekbijdrage - Hoofdstuk

The expected utility hypothesis is one of the building blocks of classical economic theory and founded on Savage's Sure-Thing Princi- ple. It has been put forward, e.g. by situations such as the Allais and Ells- berg paradoxes, that real-life situations can violate Savage's Sure-Thing Principle and hence also expected utility. We analyze how this violation is connected to the presence of the 'disjunction effect' of decision theory and use our earlier study of this effect in concept theory to put forward an explanation of the violation of Savage's Sure-Thing Principle, namely the presence of 'quantum conceptual thought' next to 'classical logical thought' within a double layer structure of human thought during the decision process. Quantum conceptual thought can be modeled math- ematically by the quantum mechanical formalism, which we illustrate by modeling the Hawaii problem situation -- a well-known example of the disjunction effect -- generated by the entire conceptual landscape surrounding the decision situation.
