Abstract
The expected utility hypothesis is one of the building blocks of classical economic theory and founded on Savage's SureThing Principle. It has been put forward, e.g. by situations such as the Allais and Ellsberg paradoxes, that reallife situations can violate Savage's SureThing 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 SureThing 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 mathematically by the quantum mechanical formalism, which we illustrate by modeling the Hawaii problem situation, a wellknown example of the disjunction effect, and we show how the dynamics in the Hawaii problem situation is generated by the whole conceptual landscape surrounding the decision situation.
