Center squeeze: Difference between revisions

Line 53:

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

Systems that generally do well with center squeeze include [[Condorcet method|Condorcet systems]]. Some people suggest that a center squeeze scenario could become an opportunity for one of the wings to use burial strategy and create an artificial [[Condorcet paradox|Condorcet cycle]]. However, a Condorcet ~~cycle~~ ~~has~~ ~~yet~~ to to be ~~documented~~ in a real-world set of ranked ballots, ~~and~~ purposefully trying to inducing a cycle by voting for less-preferred candidates risks getting the less-preferred candidates elected.

Systems that generally do well with center squeeze include [[Condorcet method|Condorcet systems]]. Some people suggest that a center squeeze scenario could become an opportunity for one of the wings to use burial strategy and create an artificial [[Condorcet paradox|Condorcet cycle]]. However, Condorcet cycles are exceedingly rare: only one instance is known for a real-world set of ranked ballots. Furthermore, purposefully trying to inducing a cycle by voting for less-preferred candidates risks getting the less-preferred candidates elected.

Center squeeze is also a feature of two-party systems which use a [[primary election|primary]] to select candidates. In this case, the two parties tend to separate ideologically, and a "center" candidate, ideologically between the two, would find themselves unable to win a primary against another candidate closer to the centroid of the party. The center candidate would win in any one-on-one vote over the whole voting population, but will not win in the subset of the population represented by a party.
