My point is that the giveaway incentive can indicate a deeper problem <br>
that degrades the quality of the outcomes.<br>
<br>
Suppose voters who don't want to compromise vote where to relocate their <br>
capital. They all vote honestly, none of them compromises. They use IRV. <br>
As a result, the capital is placed in the most populous subregion of the <br>
most populous region, instead of the place that minimizes the sum of <br>
distances to the voters. Even though the voters honestly listed their <br>
candidate sites in order of closest first.<br>
<br>
You could say that the compromise incentive is separate from the <br>
propensity to elect the strongest wing of the strongest wing <br>
(recursively). But it's this dynamic that produces the compromise <br>
incentive in IRV, so they are connected.<br>

<br>
Why doesn't this argument work for a hypothetical ranked Plurality?<br>
<br>
"An electorate that has enacted a variant of Plurality where everybody <br>
ranks the candidates in order of preference and then the candidate with <br>
the most first preferences wins ... didn't do so because they want to <br>
vote someone they don't like over their favorite. They want rankings <br>
because they want to rank sincerely. They will. No problem."<br>
<br>
Just like IRV, Plurality has absolutely no burial incentive. Just like <br>
IRV, Plurality has a rather large compromise incentive. But that <br>
shouldn't matter if the voters have decided they're not going to <br>
compromise, right?<br>
<br>
Something seems off. "Ranked Plurality" would be a non-starter; nobody <br>
would go for it.<br>
