found that TopMedianRating returned fewer Condorcet winners than<br>
average-based range voting.<br></blockquote><div><br></div><div>In that sim, Range elected 13279/29999 CWs, and Median elected 12472/29999. This is a significant difference, but not a huge one. On the other hand are two effects:</div>
<div>1. Range's greater strategy incentive</div><div>2. The tendency for voters to polarize, giving exactly one of the two frontrunners an <i>honest</i> rating near zero. This is a <i>separate</i> effect from strategic exaggeration. If true, this tendency increases the probability that an honest median vote is strategically strongest, but does not do as much for Range.</div>

I believe these sims were conducted with random tie-breaking though<br>
(not Balinski-Laraki<br>
nonrandom tiebreak method).<br></blockquote><div><br></div><div>I suspect you used enough rating categories (100?) that the difference is immaterial there.</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">

Maybe you should do sims first, emit flames second.<br>
