Talk:Participation criterion: Difference between revisions

: Thanks for catching this. Edit: Actually, I didn't say "A can't be hurt by adding bullet votes for A", I said the voter can't be hurt by bullet voting. So consider that in IRV and STAR, adding a bullet vote could help a voter's favorite eliminate their lesser evil, and then their favorite loses later rounds. For Condorcet, while I am not admittedly not being rigorous there, I'm sure that adding bullet votes for Favorite could similarly start a Condorcet cycle that helps elect a Greater evil.

:: Then that criterion is not a variant of Participation. Participation says "if you show up and cast a ballot that ranks X over Y, then that shouldn't change the winner from X to Y". A bullet vote for X ranks X above everybody else, so there's only a Participation violation if the outcome changes from X to someone who isn't X.

:: Thinking about it a bit more, it seems your criterion is closer to "If a voter shows up and equal-ranks a set S of candidates at the bottom, then that shouldn't change the outcome from someone in S to someone else in S". It's a sort of "reverse no favorite betrayal". [[User:Kristomun|Kristomun]] ([[User talk:Kristomun|talk]]) 13:46, 14 May 2020 (UTC)
