Query: Representing Attitudes Towards Ambiguity in Hilbert Space: Foundations
  and Applications   We provide here a general mathematical framework to model attitudes towards
ambiguity which uses the formalism of quantum theory as a ``purely mathematical
formalism, detached from any physical interpretation''. We show that the
quantum-theoretic framework enables modelling of the "Ellsberg paradox", but it
also successfully applies to more concrete human decision-making (DM) tests
involving financial, managerial and medical decisions. In particular, we
elaborate a mathematical representation of various empirical studies which
reveal that attitudes of managers towards uncertainty shift from "ambiguity
seeking" to "ambiguity aversion", and viceversa, thus exhibiting "hope effects"
and "fear effects". The present framework provides a promising direction
towards the development of a unified theory of decisions in the presence of
uncertainty.
