What are you really buying when you buy a lottery ticket?

Lotteries are a great place to study human misjudgment. They take your money and sell you a dream.

A lottery ticket is the ultimate example of the possibility effect. Without a ticket you cannot win, with a ticket you have a chance, and whether the chance is tiny or merely small matters little. Of course, what people acquire with a ticket is more than a chance to win; it is the right to dream pleasantly of winning
