Method evaluation poll 2008

From Electowiki
Jump to navigation Jump to search

Please rate the following single-winner methods on a scale from 0 to 10, on functional merit alone. That is, leaving the issue of public salability aside, how well will the method perform in a large, contentious electorate? Decimal ratings are allowed.

The answers you give on your first pass through the survey need not be final. Please feel free to change/update your answers as many times as you like. You may leave a question mark next to your score for a given method if you are particularly uncertain about that score, and you may also substitute a question mark for the number if you feel unable to evalute the method.

Feel free to add more methods to the poll, especially interesting ones! This goes without saying, but please don't change other people's ratings! Try to keep the columns tidy so that it's clear whose scores are whose. The format of this poll is based on that of the essential questions poll. Please identify yourself by your initials in the body of the poll, and in the participants section at the top of the poll. This poll will be ongoing; that is, it has no closing date. Also, there is no official tally method, and no official winner will be declared.
