If it is any consolation, it is the only class where a reversal can happen with only three candidates. You need at least one sincere truncated ballot from the start. However the equations even let you some freedom. If I do not mess again, >3: A >2: A >B >C >2: B >A >C >2: B >C >A >3: C should show the same behavior... The relative fraction of cases is small, but the number of cases is infinite (except if you restrict the total number of voters). However, it seems the relative fraction would growth fast when increasing the number of candidates. I have not verified if a sincere truncated ballot is necessary for 4 candidates or more.
What surprises me is the fact that there is a sincere Condorcet winner from the start. Sorry Bart if I misleaded you. Steph. ---- For more information about this list (subscribe, unsubscribe, FAQ, etc), please see http://www.eskimo.com/~robla/em
