Good answer, this has a nice property that it can be applied to any reasonably behaved average-based system to get an honest mechanism. For a plain average it is equivalent to the median.
- ajennings 9y agoNot actually equivalent to the median. If all the scores are 1s and 5s, then the median will be a 1 or a 5, but the average will be somewhere in between. The problem is slightly easier to understand if we consider the grading scale from 0 to 100. Then every agent, trying to manipulate the score as much as they can toward their "ideal grade", will submit a grade of 0 or 100. The average will converge to the unique number, X, where X percent of the graders want the final grade to be above (or equal to) X.
- paulgb 9y agoYes, you're right and I was wrong.
