Abstract: The different options people select from a set of non-rival alternatives are compared in terms of singularity. A criterion for ranking these choices on the basis of the number of other choices from which they differ is introduced and characterized. An axiomatic characterization of the ranking of choice profiles based on the aggregation of the singularities of the chosen alternatives is also provided.
