What Is Voter Satisfaction Efficiency?
These results aren&#x27;t passing the sniff-test for me.<p>If I understand, &quot;honest&quot; voters in the score-like systems stick to some magically-shared mapping of their own utility to scores on the ballot (totally unreasonable, but let&#x27;s grant it). Strategic voters, meanwhile, just use the ballots to maximize their own utility.<p>Let&#x27;s take the simplest, common scenario of two clear frontrunners. In score voting&#x27;s one-sided strategic scenarios:
- Honest voters who support candidate A will put down magical normally-distributed numbers. Their scores for A end up perhaps 10-50% higher than their scores for B.
- Strategic voters who support candidate B will maximize B&#x27;s chance of winning by putting down the highest score for B and the lowest score for A. Score for B will be uniformly 100% higher than scores for B.<p>In this scenario it takes perhaps 2-10 honest A voters for every strategic B voter for A to win. Yet somehow, the VSE for 1-sided strategic score scenarios are all much better than plurality, and equal with approval?<p>This is a commonly-discussed downside for any score voting system, where it gives strategic voters extra power, and, in these 1-sided scenarios, is worse than plurality. The downside is appearing nowhere in this data.
