Highlights: • Proposition of a pairwise comparison function based on the exponential function • Adaptation of the utility function with the proposed exponential function • Comparative analysis with the original and the adapted versions of the utility function • Empirical demonstration of the better predictions from the adapted utility function ABSTRACT This research aimed to replace the pairwise comparison function used in Leoneti [2016] with a new function inspired on the exponential model of

A field study consisting of solving three cases in a group was proposed to evaluate the number of matches of the method regarding the decision negotiated by the group, and the number of times that, when there was a match, the group maintained its decision after voting. From an empirical evaluation with a hundred students that participated in the field study, the main hypothesis of this research was confirmed, which is that the use of a pairwise comparison function adhering to a decision and judgment theory increases the predictive capacity of the utility function proposed in Leoneti [2016] .
