Graduated Majority Judgment: Difference between revisions

 

# Each voter grades each candidate on a grading scale such as A, B, C, D, F

# If a single candidate has a majority (that is, a number of votes greater than or equal to 50% of voters), they win.

# If more than one candidate has a majority, the last grade tallied is removed from the tallies, and then re-added at the smallest fraction possible so that some candidate has a majority. This is as if the votes at that grade were added 1% at a time until one candidate gets a majority.

 

The above process is conceptually simple, but difficult in practice. The following process gives the same results, and is simpler to run in practice:

 

# Each voter grades each candidate on a grading scale such as A, B, C, D, F

# Each grade for each candidate is tallied.

# The tallies are used to find the median grade for each candidate.

# A candidate's adjustment is a number between -0.5 and +0.5, calculated using the formula (V(>M) - V(<M)) / (2 * V(@M))

# The candidate with the highest adjustment among those with the highest median, wins.

If medians are converted to integers (such as 0-4), then the adjusted median scores can easily be reported alongside the full tallies.
