In this article we introduce a dissimilarity measure on a certain class of oriented graphs arising in the context of group decision making. Group consensus is done using Potential Method (PM) developed by the author in 2002.
Possible applications of the method are discovering hidden conflicts in society and testing a homogeneity of micro-social structures, like sport teams. Here we use it to find the outliers in the group of students whose task was to compare their lecturers in regard to a certain number of criteria.
