Simple majority may refer to: Majority , a voting requirement of more than half of all votes cast Plurality (voting) , a voting requirement of more votes cast for a proposition than for any other option
Kenneth May proved that the simple majority rule is the only "fair" ordinal decision rule, in that majority rule does not let some votes count more than others or privilege an alternative by requiring fewer votes to pass. Formally, majority rule is the only decision rule that has the following properties: [10] [11] Anonymity: the decision rule ...
In other words, this candidate preferred to any one of their opponents by a majority of voters. When there are only two candidates, a simple majority vote satisfies this condition, while for multi-candidate votes any majority-rule (Condorcet) method will satisfy it. Proof sketch: Let the median voter be Marlene. The candidate who is closest to ...

A "double majority" is a voting system which requires a majority of votes according to two separate criteria. [6] e.g. in the European Union, the Council uses a double majority rule, requiring 55% of member states, representing at least 65% of the total EU population in favor. In some cases, the required percentage of member states in favor is ...
May's theorem states that simple majority voting is the unique social welfare function satisfying all three of the following conditions: [1] Anonymity : The social choice function treats all voters the same, i.e. permuting the order of the voters does not change the result.
For example, it is the case of the simple majority vote: each voter assigns 1 point to her top alternative and 0 to the other, and the alternative with most points is declared the winner. (If both alternatives reach the same number of points, the tie is broken in an arbitrary but deterministic manner, e.g. outcome a {\displaystyle a} wins.)
