The lottery is a form of gambling that gives a small number of people the chance to win large sums of money by matching numbers that are randomly spit out on tickets. Some governments endorse and regulate the lottery, while others do not. In the United States, state lotteries are popular and have become an important source of revenue for state government.

A key reason that lotteries enjoy broad public support is their claim to benefit a specific “public good,” such as education. This argument is especially effective during periods of financial stress, when states are faced with raising taxes or cutting services. However, it is not clear that the lottery actually helps to meet these proclaimed goals. In fact, the evidence suggests that the lottery has largely failed to improve educational outcomes in the states where it has been established.

Moreover, there is evidence that the promotion of the lottery has contributed to fragmentation of state policymaking. Lottery officials and retailers develop their own internal constituencies, with the result that a general state policy on gambling is unlikely to emerge. Lottery officials also establish their own authority structure, which is often decentralized and isolated from the legislative and executive branches.
