Finding the probable best candidate? - IIA

[Steve Barney]

Rob:

Based on reading Saari's most recent books, my understanding is that the
Condorcet method, essentially voting for pairs, is the ONLY method (besides
perhaps some strange, unreasonable and completely undemocratic contrivances)
which satisfies IIA. Perhaps you are using the same name for something else.
The problem is that no method can satisfy both IIA and the condition that it
always produces non-cyclic outcomes.
