Majority Rule Advantages And Disadvantages

The first voting rule is called unanimity. It means that the outcome is agreed by all voters. In this method, each individual's preference matters, since one single disagreement can change the outcome. In this case, every individual prefers one option to another, therefore, it must result in a societal preference. This reaches Pareto improvement, making at least one person better off without making at least preference criterion worse off. Since everyone contribute to this system, free riding problem can be completely avoided.

A significant drawback of this rule is that reaching unique outcome is time-consuming, especially for large number of voters and large number of alternatives. It requires long term renegotiations over again. that

This sometimes mistaken for majority rule, they are quite similar in any situation involving only two options. For majority rule, the option with more than fifty percent is passed, and in the case of two options, the option passing fifty percent threshold is equivalent to option with most votes. However, if there are more than two alternatives, it makes these two rules different. Plurality could choose the candidate with most votes that has less than fifty percent of the votes. But with majority voting system, the candidate has to receive more than fifty percent of votes to win. An important characteristic of FPTP is that only the first preference matters, all other information is useless for the outcome. This leads to a problem that voters may not reflect their real preferences. For example, voters may forecast the one who has the best chance to win, and candidates with least vote have to face the reality that they have no chance winning the election. Therefore, such information may change how they behave, and tactical voting is possible to change the outcome. For example, it may turn out that casting a ballot for the person with more chances to defeat the candidate you dislike. As a result, most voters could become disinterested in the democratic process because they have no meaningful way to express their true preferences. What could be worse is three

"Candidate with the highest number of the vote wins the right to represent the particular seat in the House of Commons", according to CBC news. There are some limitations regarding this method. First of all, it could possibly happen that candidate with less than half vote wins, which means it only reaches minority people's desired outcome. In addition to the tactical voting, the two-party system could be a serious problem. Since only the first matters, candidates with the low possibility to win may exist the election. After exiting, they and their supporters tend to choose a candidate who has the similar ideology or one they simply dislike. It will gradually become the two-party system. The power has been held by either two largest parties. The candidate with the largest number of seats becomes Prime Minister, while the second largest become official opposition.

Voting is a widely used method for making a decision. Voting represents the collective choice, during the voting process, individuals' preferences are taken together, and eventually they aggregate their diverse opinion into a social choice. Although there are many alternative voting systems, they cannot always deliver in all situations. The reason is stated by Arrow, and it shows that it is impossible to find a perfect system.

Therefore, it is important to weigh up the strength and weakness, then choose appropriate method among various alternative
