Abstract:

During the recent decade, quantum decision-making models were established based on the mathematical structure and methodologies of quantum mechanics. Owing to its unique theoretical structure, the quantum decision-making models can be applied to explain problems that violate the classical decision models, especially for judgments under uncertainty and decisions under conflicts. Quantum decision-making models have been used to explain phenomena such as disjunction effect, conjunction fallacy and interference of categorization on decision making which are difficult to account for with classical decision models. A model called quantum question equality has been tested for its accurate prediction of order effects. Being a new research field contributing to analysis of decision making, quantum decision-making models worth further investigations both in theoretical and applicative levels.

Key words: quantum, decision making, model, probability
