Sandro Sozzo joined the University of Leicester in 2013. He is an associate professor at the School of Business in the Department of Economics Finance and Accounting (EFA) and he is also director of the Centre for Quantum Social and Cognitive Science (IQSCS). In 2017 he obtained the Italian scientific qualification for the position of Full Professor. He is managing editor of the Springer-Nature journal Foundations of Science and secretary of the International Quantum Structures Association (IQSA). He is the author of more than 90 contributions including several articles in high impact and top journals. He organized various international conferences presented more than 60 communications and was invited to give lectures in UK US Canada EU Russia and China. In 2013 he was conferred an Outstanding Scholarly Contribution Award by the International Institute for Advanced Studies in Systems Research and Cybernetics for his research. He also received a Superstar Award in 2016 2018 and 2020 by the Students’ Union for his teaching. He was invited as visiting professor to various EU institutions. He acted as Deputy Director of Internationalization and Director of PGT Finance Programmes.

Abstract:
Growing empirical evidence reveals that classical set-theoretic structures, as Boolean algebras and Kolmogorovian probabilities, cannot in general be applied to cognitive phenomena. This raises several problems, illustrated, e.g., by probability judgement errors and decision-making errors. Inspired by a two-decade research on the foundations of quantum physics, we put forward a unified theoretical perspective which applies the mathematical formalism of quantum theory in Hilbert space to cognitive domains. In this perspective, judgements and decisions under uncertainty are described as intrinsically non-deterministic processes which involve a contextual interaction between a conceptual entity and the cognitive context surrounding it. We employ the quantum-theoretic framework in a variety of judgement and decision situations where systematic deviations from classical structures occur. We show that these “deviations from classicality” can be explained as due to the presence of genuine quantum structures, in particular, emergence, entanglement, interference, and superposition. The results presented in this seminar support an emerging research programme which applies the mathematical formalism of quantum theory, detached from its physical interpretation, outside the microscopic domain of quantum physics.
