Majority obeying minority means that most voting system is based on the idea that minority obeying majority. Usually, if a plan is supported by more than half of the voters, it will be passed. However, when there are more than two options to choose from, either option may not be supported by more than half, and different voting systems will produce different results. Therefore, which voting system is adopted has an important influence on the election results.
Majority consent rule:
The so-called "majority decision system", also known as "majority voting system", refers to the voting rule that a decision must be agreed by more than half of the people. The essence of the majority voting rule is "the minority is subordinate to the majority". Because the decision-making cost of unanimous rule is very high, most people think that the rule cost is the most commonly used voting rule in practice.
