The '''Plurality-Cloaked Participation Criterion (PCPC)''' states that
<blockquote>Adding a ballot that bullet-votes for only X should neither decrease the winning probability of X, nor change the winning probabilities among the other candidates relative to each other. A method that does not allow bullet-voting for only one candidate is considered failing the criterion. -- [[User:RobLa|RobLa]] ([[User talk:RobLa|talk]]) 06:16, 26 March 2022 (UTC)</blockquote>
The '''Approval-Cloaked Participation Criterion (ACPC)''' is a stronger requirement which states that
Line 11 ⟶ 13:
Satisfying ACPC does not imply compliance with the Participation Criterion but protection for semi-honest voters (those who compress their true preferences) against the No-Show Paradox.
Everything that passes the [[participation criterion]] pass these criteria. It is not known if there exist any methods that don't pass [[participation criterion|participation]] but pass either ACPC or PCPC.
Methods that fail both ACPC and PCPC: [[Instant-runoff voting|IRV]], [[Runoff voting]] in general, [[Bucklin voting|Bucklin]], the [[Schulze method]].
