We propose a new parametrization of Quantum Decision Theory (QDT), based on Rank Dependent Utility Theory (RDU). Using … experimental data made of choices between pairs of lotteries, we compare QDT with "classical" decision theories, RDU and Cumulative … decision makers as either RDU, RDU-based QDT, CPT or CPT-based QDT. Our major findings are the following: the quantum …

We assess the ability of different risk profiling measures to predict risk taking along a multi-stage decision process …-assessed risk tolerance measures are not suitable for predicting risk taking in any stage of the decision process. Among the …

Quantum decision theory (QDT) is a recently developed theory of decision making based on the mathematics of Hilbert … decision making. QDT describes a decision maker's choice as a stochastic event occurring with a probability that is the sum of … subjectivity on decision makers, the quarter law. We examine individual and aggregated (group) data, and find that the results are …

We present the first calibration of quantum decision theory (QDT) to an empirical data set. The data comprise 91 …. The prediction of choice reversal is then refined by introducing heterogeneity between decision makers through a … differentiation of the population into two similar sized groups in terms of "over-confident" and "contrarian" decision makers. This …
