Modelling Decision Making Uncertainty and Contextuality

Human cognition and decision making have always baffled thinkers from time immemorial. More recently over the last decade or so, there has been keen interest in studying the ‘mind’ from a ‘non-classical’ logic perspective. Mathematically, the standard Kolmogorov measure theory based framework for decision-making has been challenged. It has been suggested that the human mind might be better described by ‘quantum’ or ‘quantum-like’ logic rather than by binary or Boolean logic. In particular, contextuality, uncertainty and non-locality in cognition have been studied in that context. In this paper we outline an alternative non-quantum framework which is mathematically equivalent to the quantum framework but free of its vexing interpretational problems. In particular, we explore decision making under ambiguity and contextuality.
