text: Referendums When the citizens of a country are invited to vote, they are participating in an election. However, people can also vote in referendums and initiatives. Since the end of the eighteenth century, more than five hundred national referendums (including initiatives) were organized in the world; among them, more than three hundred were held in Switzerland. Australia ranked second with dozens of referendums.
  Most referendums are binary.  The first multi-option referendum was held in New Zealand in 1894, and most of them are conducted under a two-round system.  New Zealand had a five-option referendum in 1992, while Guam had a six-option plebiscite in 1982, which also offered a blank option, in case some voters wanted to (campaign and) vote for a seventh option.
  Fair voting
  The results of an election may lead to confusion, and in extreme cases, could lead to violence and even a civil war. Many alternatives may fall in the latitude of indifference—they are neither accepted nor rejected.
  There are social choice theory definitions of seemingly reasonable criteria that are a measure of the fairness of certain aspects of voting, including non-dictatorship, unrestricted domain, non-imposition, Pareto efficiency, and independence of irrelevant alternatives.  However, Arrow's impossibility theorem states that no voting system can meet all these standards.
  To ensure fair voting and to prevent the misuse of its microblogging platform, Twitter announced that it was going to be adding a feature for its users to be able to report content that misleads voters.
