Bucklin, Score, and center squeeze

Systems which can do either well or poorly in a center squeeze situation include most graded Bucklin systems and score voting.

Under what circumstances do they not do well? — Psephomancy (talk) 03:44, 6 February 2019 (UTC)

Questions about center squeeze

I think center squeeze is an interesting criterion & it's valuable to compare systems which exhibit it vs don't exhibit it. Some questions:

• Is there an existing criterion that is a superset of exhibiting/preventing center squeeze? What I mean is, is there a criterion that if met by a voting system, center squeeze can never happen?
• If not, is "exhibits center squeeze" worthy of a criterion?
• Lastly, whether or not it's called out as a criterion, what voting systems do & don't exhibit it?

"Liberal" and "Conservative"

In section Center_squeeze#Effect_of_strategy, I would suggest not using real party/ideology names like "Liberal" or "Conservative", as this will often be misunderstood as advocating in favor of a "Centrist" or moderate winner. (FairVote conflates these concepts on https://fairvote.org/why-the-condorcet-criterion-is-less-important-than-it-seems/ when they say "Condorcet winners are centrist by nature, regardless of the preferences of the electorate" and "choosing the centrist candidate every time is just falling into the fallacy of the middle ground".)

Center-squeeze is bad because it elects poor representatives, not because it elects non-centrists on some absolute spectrum. If the voters are all pro-women's suffrage extremists and anti-prohibition extremists, then a good voting system that doesn't suffer from "center-squeeze" would elect a pro-suffrage and anti-prohibition candidate, not someone who is centrist on both issues. It's an unfortunate name, we should try not to reinforce this misconception. — Psephomancy (talk) 02:43, 14 May 2023 (UTC)

Feel free to edit this section to your liking (though expect others, like me, to swoop in and change what you wrote, possibly reverting your change). The section was originally added by User:BetterVotingAdvocacy in 2020 (see https://electowiki.org/w/index.php?title=Center_squeeze&diff=prev&oldid=8773 ) and could use some copyediting (such as the RanSOM noTE capitalIZATION). Personally, I suspect that most voters (even outside of the United States) think of the political spectrum as a single-dimensional space with "left-wing politics" and "right-wing politics", so it's difficult NOT to talk about electoral issues without describing the two traditional extremes in political discourse, but I'd be happy to see a different version of this section. -- RobLa (talk) 20:15, 14 May 2023 (UTC)

I need a different example.

I have an improved version of IRV that is not vulnerable in the example given. I would elect B (the Condorcet winner). Can I claim that it is not vulnerable or much less vulnerable? (Is it still considered IRV? See the link on my user page). RalphInOttawa (talk) 16:58, 13 December 2023 (UTC)

I don't think there's a formalized "center squeeze criterion". But as an indication, you could try to see if your IRV version elects Center in every configuration of the Left, Center, Right scenario; that is, all possible elections with x < 50%, y < 50%, x + y > 50%, where x, y, z are defined as on that page.
