The Public Interest and the Lottery

  • by


In the United States, lotteries are popular fundraising devices used to provide money for a wide range of public purposes. A lottery is a game in which numbers are drawn and the person with the winning combination wins a prize. This is a form of gambling, and the practice of lotteries dates back centuries. The Old Testament has several references to the casting of lots, and Roman emperors used them to give away land and slaves. In the early American colonies, Benjamin Franklin and George Washington managed lotteries to raise funds for military supplies. Today, state-sponsored lotteries generate billions of dollars a year for education, transportation, and other needs.

Many lottery games feature a top prize that grows to an apparently newsworthy amount for the purpose of increasing sales and drawing attention from media outlets. The size of the top prize, however, is not the only factor that drives ticket purchases; the likelihood of winning also makes a difference. If the probability of winning is low enough, a ticket purchase may still be a rational choice for an individual who values entertainment or other non-monetary benefits that the prize will bring.

The state-sponsored lottery is a business that must maximize revenue in order to function, and its marketing strategy necessarily relies on persuading people to spend their money. But the question is whether this business model, which entails advertising that promotes gambling to potentially vulnerable groups, works at cross-purposes with the public interest. And is it appropriate for state governments to run a gambling industry that promotes the exploitation of poorer citizens and problem gamblers?

State lotteries are a classic example of a piecemeal and incremental development in which policy decisions are made by localities with little or no overall overview. Moreover, the lotteries are subject to constant pressure for additional revenues, which results in an ongoing evolution that takes general public welfare into consideration only intermittently and at best tenuously.

Before the mid-1970s, state lotteries were little more than traditional raffles in which the public bought tickets for a drawing at some future date, often weeks or months. Innovations in the 1970s, however, radically transformed the industry. For example, the advent of scratch-off tickets allowed lotteries to offer prizes on the scale of 10s and 100s of dollars, with relatively high odds of winning on the order of 1 in 10.

One such innovation was the use of a computer to select numbers instead of a human being, which greatly improved the accuracy of results. Moreover, the computer could quickly determine which numbers were being purchased by regular players and which were being purchased by infrequent players. This information could then be used to target marketing efforts.

Another way to improve your chances of winning is to choose the most populated numbers. Avoid choosing the obvious, such as birthdays or anniversaries, which are already well-traveled. Instead, try a number from the range of 1 to 31. Remember to keep your ticket somewhere safe and check it after the drawing.
