[EM] An MCA Method: the Majority Judgment

[Andy Jennings]

Much has been said here lately about MCA methods.  French professors Michel
Balinski and Rida Laraki have just published a book about an MCA method, the
Majority Judgment:

As with all MCA methods, if there is a unique candidate who has the highest
median grade, he is the winner.  Here are some other details:

- If there are an even number of voters, the lower of the two middle grades
is used instead of the arithmetic median (which is the average of the two
middle grades).

- Ties are broken by removing one copy of the median grade from the set of
votes and repeating.

- They argue for using six grades, specified lingustically not numerically.
 They suggest: Excellent, Very Good, Good, Acceptable, Poor, and To Reject
