This paper explores how people make decisions about lotteries using a theory called cumulative prospect theory. The researchers looked at different ways people think about risk when choosing between lotteries with different outcomes. They found that when people start from their current situation, they don't show a certain type of risk behavior, but they do show it when starting from other points. Depending on the size of the lottery payouts, people can make smart or risky choices. Also, people can have a mix of different risk attitudes when making decisions. The researchers compared their findings with previous studies and were able to resolve some conflicting results about how people think about risk.
