I don't recommend using Equilibrium Average (which I usually call AAR
DSV, for Average-Approval-Rating DSV) to elect winner(s) from a finite
number of candidates.  AAR DSV is nonmanipulable when selecting a single
outcome from a one-dimensional range, just as median (if implemented
carefully) is, but it is manipulable when used as a scoring function in
a way similar to how Balinski and Laraki proposed using median:

For more on AAR DSV, please see chapter 3 of my now-completed
dissertation:
