Abstract: Machine-implemented methods and computer systems are disclosed for determining a collective outcome for a survey from a plurality of potential outcomes. Each outcome is a particular combination of options. Each survey participant ranks the options to develop an influent function. For each participant, the influent function is applied to each potential outcome to determine a satisfaction score for the outcome. Resistance to each outcome due to procedural/distributive unfairness is determined. The potential outcomes are ordered based on the satisfaction scores and the resistance to each of the potential outcomes. In particular embodiments, the methods and systems aim to determine a collective outcome that achieves greatest satisfaction and minimizes dissonance among the participants.
