With the right hand, you rate the raters. So each of us gets a clue stick and goes around whacking good editors "good rater" rate up a notch by voting for them as raters.
With the left hand, you rate the articles, and when other editors agree with you, they whack you and your "good rater" score goes up.
Now with the giant nose of Zenobia, you multiply the article rating by the raters rating, and average.
Thusly and so, articles get a good rating based on the best raters rating them good, and nasty bad evil raters, ratings fall into the first circle (i.e. they are weighted as nothing).
