18.1 Voter participation and costs of elections  (Page 13/9)

In U.S. presidential elections over the last few decades, about 55% to 65% of voting-age citizens actually voted, according to the U.S. Census. In congressional elections when there is no presidential race, or in local elections, the turnout is typically lower, often less than half the eligible voters. In other countries, the share of adults who vote is often higher. For example, in national elections since the 1980s in Germany, Spain, and France, about 75% to 80% of those of voting age cast ballots. Even this total falls well short of 100%. Some countries have laws that require voting, among them Australia, Belgium, Italy, Greece, Turkey, Singapore, and most Latin American nations. At the time the United States was founded, voting was mandatory in Virginia, Maryland, Delaware, and Georgia. Even if the law can require people to vote, however, no law can require that each voter cast an informed or a thoughtful vote. Moreover, in the United States and in most countries around the world, the freedom to vote has also typically meant the freedom not to vote.

Why do people not vote? Perhaps they do not care too much about who wins, or they are uninformed about who is running, or they do not believe their vote will matter or change their lives in any way. Indeed, these reasons are probably tied together, since people who do not believe their vote matters will not bother to become informed or care who wins. Economists have suggested why a utility-maximizing person might rationally decide not to vote or not to become informed about the election. While a few elections in very small towns may be decided by a single vote, in most elections of any size, the margin of victory is measured in hundreds, thousands, or even millions of votes. A rational voter will recognize that one vote is extremely unlikely to make a difference. This theory of rational ignorance    holds that people will not vote if the costs of becoming informed and voting are too high, or they feel their vote will not be decisive in the election.

In a 1957 work, An Economic Theory of Democracy , the economist Anthony Downs stated the problem this way: “It seems probable that for a great many citizens in a democracy, rational behavior excludes any investment whatever in political information per se. No matter how significant a difference between parties is revealed to the rational citizen by his free information, or how uncertain he is about which party to support, he realizes that his vote has almost no chance of influencing the outcome… He will not even utilize all the free information available, since assimilating it takes time.” In his classic 1948 novel Walden Two , the psychologist B. F. Skinner puts the issue even more succinctly via one of his characters, who states: “The chance that one man’s vote will decide the issue in a national election…is less than the chance that he will be killed on his way to the polls.” The following Clear It Up feature explores another aspect of the election process: spending.
