The well-known swap distance (Kemeny (1959); Kendall (1938); Hamming (1950)) is analyzed.
On weak preferences, this function was characterized by Kemeny (1959) with five conditions;
metric, betweenness, neutrality, reducibility, and normalization. We show that the same result
can be achieved without the reducibility condition, therefore, the original five conditions are
not logically independent. We provide a new and logically independent characterization of the
Kemeny distance and provide some insight to further analyze distance functions on preferences.
