04/05/02 - Monotonicity is `Much Ado About Nothing':
Greetings list,
My claim that your examples are unrealistic has to do with the lower choices.
Below are ballots from one ward of a Preference Voting/STV election in the
city of Cambridge, Mass. These are real ballots from a real election in
the real world. The lower choices are also real.
Your assignment, if you care to accept, is to work all these ballots as an
IRVing election and then make your two percent changes to the ballots so as
to prove non-monotonicity. Be wary of only using the ballots of only a few
candidates. You may not have enough lower choices from the few to suit
your needs. The lower choices of these ballots are divided between
nineteen candidates.
If you object to using Preference Voting ballots as an IRVing election,
then I suggest that you run the ballots as a Preference Voting election,
make your two percent changes, prove your non-monotonicity. Preference
Voting is also accused of being non-monotonic.
But, even if you are able to show non-monotonicity, I still contend that
after you make changes, the election becomes a new and different election
with possible new results.
In other words, non-monotonicity is `Much Ado About Nothing'.
Regards, Donald Davison
