A lottery is an arrangement in which prizes, such as cash or goods, are allocated to ticket holders by a process that relies mainly on chance. It is generally administered by a government as a way of raising money, though some private corporations also run lotteries. In the United States, the prizes of state-administered lotteries are often distributed to initiatives such as education and addiction treatment.

The odds of winning a lottery are infinitesimal, but people still buy tickets. One reason is that there’s a “pleasure and excitement in trying for the win,” says New York City-based clinical psychotherapist Fern Kazlow. But there’s more going on than that, she adds: Lottery advertising features stories of previous winners and dreams of wealth to evoke aspirations in lottery players.

Lottery proceeds often go toward programs like schools and veterans’ health care, and they account for a small percentage of state revenue. But they’re a big part of the marketing mix for state governments, which often try to frame the games as a “painless form of taxation.”

When states promote the idea that people are always gambling anyway, it obscures the regressivity of lotteries and the fact that the biggest players tend to be low-income, less educated, and nonwhite. It’s also a message that plays on people’s fears about the insecurity of jobs and housing, and the notion that the lottery is their only chance to get ahead. The truth is that most of us are just gambling, and we’re not all winning.
