Lottery is a state-run contest promising large sums of money to winners. In practice, the term “lottery” covers any competition where chance plays a role—such as a school admission lottery for kindergarten or housing in a subsidized community, a sports draft for the best pick of the college players, or a contest to select participants for a dangerous experiment. A lottery may be cash-based or non-cash, but it always involves selecting participants at random.
Despite the fact that making decisions and determining fates by casting lots has a long history (including several instances in the Bible), the use of lotteries for material gain is of more recent origin. The first recorded public lotteries to distribute prize money were conducted in the Low Countries in the 15th century for town repairs and the assistance of the poor. Benjamin Franklin’s attempt to sponsor a lottery in order to raise funds for cannons to defend Philadelphia during the American Revolution was unsuccessful.
As the popularity of lotteries grew, states established their own agencies and corporations to run them, creating a government-monopoly. While this arrangement has its benefits, it also creates a conflict of interest between the goals of the lottery and the general welfare. State officials are pressured to maximize revenues and thus focus on promoting the lottery by encouraging people to play. This often translates into advertising that emphasizes the likelihood of winning a prize, and it can have negative consequences for those who are vulnerable to gambling addictions.
The public has generally been supportive of lotteries, especially when the proceeds are perceived as benefiting a particular public good such as education. In addition, the large jackpots are a powerful draw, and announcing them on television gives them free publicity.
Many strategies are advertised as ways to increase your chances of winning the lottery, such as picking numbers that are significant to you or in sequences used by hundreds of others (e.g., 1-2-3-4-5-7). According to Harvard statistics professor Mark Glickman, however, this is no more effective than picking your lucky numbers randomly. Choosing numbers that are repeated in the lottery, such as birthdays or ages, increases your chances of being selected, but only by a small margin.
The growth of state lotteries has been fueled by the rise of new forms of gambling, including games like keno and video poker, and by increasing marketing efforts. Yet this evolution of lotteries often occurs without a comprehensive policy or even an overall goal in mind. As a result, lottery officials have limited ability to control the growth of the industry or its impact on vulnerable groups.
