Lotteries are a classic example of public policy driven by market forces and at cross-purposes with the larger public interest. The state legislates a monopoly for itself; establishes a government agency or public corporation to run it (as opposed to licensing a private firm in exchange for a percentage of profits); begins operations with a modest number of relatively simple games; and, due to constant pressure to generate revenues, gradually expands the lottery in size and complexity.

The underlying rationale behind the expansion of the lottery is that it increases revenues for state governments without imposing taxes on ordinary citizens. Moreover, state officials can use the proceeds to address social problems such as problem gambling or help the poor. But lottery critics argue that the premise behind this argument is flawed. It is hard to believe that a lottery that generates revenue of tens of billions of dollars annually can have a significant impact on the lives of average Americans, especially given the fact that a large proportion of winnings is paid out in one lump sum rather than an annuity.

Many lottery players employ tactics they think or hope will improve their odds of winning, from picking numbers that are associated with important dates (such as birthdays) to buying Quick Picks instead of selecting individual numbers. But Harvard statistics professor Mark Glickman says these strategies don’t work.

Ultimately, the success of a lottery depends on people’s willingness to buy tickets. And while it is true that humans develop an intuitive sense for how likely risks and rewards are within their own experiences, this intuition does not translate well to the vast scope of the lottery’s prizes. Moreover, people have difficulty understanding that the chances of winning are far more improbable than advertised.
