Yes, I fully agree on that point; nobody I know likes it when the nurse
asks how much it hurts on a scale of one to ten!

FROM: Steve

Thank you for forcing me to see that no voting method, including MJ, can
"guarantee" that its winner will be supported by an absolute majority of
all the ballots cast. MJ guarantees this only if an absolute majority of
all the ballots cast for at least one candidate have awarded them a grade
of at least Acceptable. Otherwise, the MJ winner is the candidate who has
received a plurality of such grades.

In these circumstances, electing this plurality candidate is justified by
the democratic assumption that other things being equal, a candidate with
more votes than other candidates is probably more suited for office. For
the same reason, an absolute majority candidate is probably more suited
than a winning candidate with less support than a majority.

At the same time, do you disagree with me that compared to voting by using
marks, numbers, or rankings; grading candidates allows voters more
meaningfully and informatively to express their qualitative judgments about
the candidates?

I look forward to our next dialogue.
Steve

Subject: Deterministic Epsilon Consensus Idea stimulated by a question
of Steve Bosworth (was Election-Methods Digest, Vol 207, Issue 9)

Steve's query about Chiastic Approval included the following ....

Also, correct me if I'm mistaken that XA does not guarantee that its
winner will be elected with the support of a majority of all the votes
(ballots) cast.

The short answer is "no" ...  no method can guarantee majority voter
support for its winner, unless they can guarantee that at least one
candidate is ranked, rated, scored, or graded above bottom on more than
half of the ballots submitted.

The long answer is, "Why stop at half or two-thirds, as some methods
require ... why not go for full 100% consensus?"

But, you may object, full consensus is not always possible. Well, neither
is forty percent support always possible, but that doesn't stop the
Constitution from requiring two-thirds of the voters' support for certain
kinds of amendments, etc.

One expedient that has been suggested is the NOTA option for the case when
the quota is not met.  This option gives new meaning to the word "approval"
... as Mike Ossipoff used to say, you approve a candidate if you would
rather see her elected than have to come back next month to vote for
someone else.

I would like to suggest another option based on the standard MJ grade
ballot ...

Each candidate X gets a score that is given by the sum ..

S(X) = Sum (over j from zero to five) of the product

a(j)*epsilon^j,

where epsilon is a value to be determined by the voters ... and the
respective values of a(j), for j in {0, 1, 2, 3, 4} are the number of
ballots on which candidate X is graded strictly above reject, poor,
acceptable, good, or very good, respectively.

Also each voter has the option of voting for a value of epsilon in the set
{.01, .02, ... .99, 1.00}. The median of the distribution of these votes
determines the value of epsilon.

Elect the candidate X with the max value of S(X) (once the epsilon value
has been determined).

Note that if, for some j, the coefficient a(j) is the total number of
ballots, then we can say candidate X is a full consensus candidate at level
j.

If there are several full consensus level j candidates, then the higher
degree terms will determine the winner.

Thanks!
