At least half of men don't wash their hands before leaving a public restroom. Literally everything is covered in dick stuff. Source: 30+ years of using public restrooms as a male.

The McKelvey–Schofield chaos theorem proves that, if an electorate is presented with a series of proposed policy changes and everyone votes according to their honest preference, the proposals can be fashioned and ordered in such a way that any policy can be made to win—even one that no voter prefers to the starting point.

Could you source the "even one that no voter prefers to the starting point" part?

There will in most cases be no Condorcet winner and any policy can be enacted through a sequence of votes, regardless of the original policy. This means that adding more policies and changing the order of votes ("agenda manipulation") can be used to arbitrarily pick the winner.

The article doesn’t explicitly say that this includes policies not preferred by any single voter, but it’s implied by “any” and “arbitrary” (and can be verified by the original theorems).

I'm not too familiar in the field, but doesn't a policy have to appeal more to a specific base than its appeal to another base to cause a Cordocet tie?

[-] AbouBenAdhem@lemmy.world 2 points 4 hours ago

Yeah, the Condorcet criterion is a lot more restrictive in the space of policies (where you can make incremental changes in any direction) than in elections for a discrete set of candidates. (Which is why they say that in most cases there won’t be one.)

[-] Aatube@kbin.melroy.org 1 points 2 hours ago

Yeah, so in my understanding of that, doesn’t that mean the winning policy has to appeal more to a voter base than one that appeals to another voter base?
