I know that all those things were known before I joined this list.
The unique reason why you discussed only MinMax and Copeland is that
you wanted to give to other people the possibility to introduce new
methods to this list. ;-)
I was just surprised that you posted your IRO bad examples shortly
after this topic has been discussed in great detail in December 1999.
I just thought that you wanted to show with your IRO bad examples
something interesting that hasn't been discussed in that discussion
in December 1999. :-o

There was the discussion whether Moulin's participation criterion
presumes sincere or sophisticated voters. I wrote that and why
Moulin presumes sincere voters (5 May 2000). Also Steve came to
the conclusion that Moulin presumes sincere voters (5 May 2000).
There was the discussion whether sincere or sophisticated voters
should be presumed. You (5 May 2000) and Steve (5 May 2000)
wrote that sophisticated voters should be presumed because it is
unrealistic for real elections that the voters vote sincerely.
I wrote that sincere voters should be presumed because -unless
additional presumptions about the used strategies are made- it is
not unique how a sophisticated voter with a given opinion votes
(5 May 2000).
SARC was merely mentioned. The definition of SARC wasn't
mentioned at all in this discussion.
