A lottery is a game of chance in which numbers or symbols are drawn at random to determine a prize. This form of gambling is popular in many states and can be used for public or private purposes. Some states prohibit lotteries, while others endorse them and regulate them. The lottery is an important source of revenue for state governments in an anti-tax era. Government officials are pressured to increase lottery revenues and to expand the number of games offered. Whether or not lotteries are ethical, they can be very addictive for players.
The distribution of property, slaves, or other goods by drawing lots has a long record in human history, including numerous instances in the Bible and dozens of Roman emperors’ Saturnalian dinner entertainments (including an event called the “apophoreta,” in which guests received pieces of wood bearing symbols to be raffled off at the end of the meal). Public lotteries were common in the medieval Low Countries, where records from towns such as Ghent, Utrecht, and Bruges indicate that they were widely used for municipal repairs, town fortifications, and to help the poor.
Modern state lotteries are often established with a legislative monopoly and a publicly owned corporation or agency to manage them. They typically begin operations with a modest number of relatively simple games and then, because of a constant demand for additional revenues, progressively increase the scope of their offerings by adding new games. As a result, most state lotteries have a pronounced and sometimes intractable growth pattern.
When the odds are very long against winning a prize, it can be difficult to understand that it’s unlikely you’ll win. This is a phenomenon known as the escalating horizon of improbability, and it’s an important part of what makes lottery so addictive.
When you play a lottery, it’s not only the chance that you’ll become rich that motivates you to buy tickets; it’s also the sense of gratification that comes from the belief that you’re doing your civic duty by supporting a state institution that raises money for a good cause. The messages that state lotteries communicate, therefore, can obscure the regressivity of this form of public finance.
