Quantum decision making by social agents

Decision making of agents who are members of a society is analyzed from the point of view of quantum decision theory. This generalizes the approach, developed earlier by the authors for separate individuals, to decision making under the influence of social interactions. The generalized approach not only avoids paradoxes, typical of classical decision making based on utility theory, but also explains the error-attenuation effects observed for the paradoxes occurring when decision makers, who are members of a society, consult with each other increasing in this way the available mutual information.
