Rationality, Contextuality, and Extended Probabilities

José Acacio de Barros,
San Francisco State University –
Abstract:
Rationality is often associated with classic theory of probability, which is built on top of a Boolean structure of events. However, some experimental conditions, both in physics and in the social sciences, do not permit a classic description, as this description would lead to logical contradictions. The reason for such contradictions are that experimental outcomes depend non-trivially on the context, i.e. they are contextual. In this talk we will discuss such examples and then show how classic probability theory can be modified to include contextual systems.
