Line 172:
==== Failure to pick a good compromise ====
IRV exhibits [[center squeeze]]. That means that IRV can ignore a good compromise in favor of a polarized choice that enjoys smaller actual support.
This failure mode occurs in a 3-choice election where parties A and B are bitterly opposed, and party C is first choice for a minority but tolerable for a large majority. For a real-life example, consider the 17th-century Europe struggle over "government-enforced [[Catholicism]]" versus "government-enforced [[Protestantism]]", with "freedom of private worship" as the compromise C.
