== Criteria compliance ==
 
Majority score passes the [[favorite betrayal criterion]], the [[majority criterion]].., [[Independence of irrelevant alternatives]], [[Local independence of irrelevant alternatives]] (under the assumption of fixed "honest" ratings for each voter for each candidate), [[Independence of clone alternatives]], [[Monotonicity]], (polytime) [[resolvability]], O(N) [[summability]], and [[later no help]].
 
There are a few criteria that it does not pass as such, but passes related but weaker criteria. These include:
 
* It fails the [[mutual majority criterion]], but passes if the mutual majority in question unanimously rejects all candidates outside their mutually-preferred set. It also passes if the number who give the strongest candidate in the set a rating below "support" is less than three times the amount by which the overall group exceeds 50%.
 
* It fails the [[Condorcet criterion]], but for any set of voters such that an honest majority Condorcet winner exists, there always exists a strong equilibrium set of strictly semi-honest majority score ballots that elects that CW.
 
* It fails the [[participation criterion]] but passes the [[semi-honest participation criterion]].
 
It fails the [[consistency criterion]], the [[Condorcet loser criterion]], the [[majority loser criterion]], and the [[later no-harm criterion]].
