Before revision: 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.
