Probability and chance can be mentally difficult to process, so humans are overly swayed by the allure of a lottery. For example, many people purchase lottery tickets even though the expected value of doing so is negative. As an extreme example, people spend $2 for a 1-in-292,000,000 chance of winning $50,000,000.

To encourage someone to do an action, consider creating a lottery with a cash or non-monetary prize.

  • Surveys frequently offer you entry into a lottery once you have fully completed the survey, with various prizes depending on the survey.

  • Lotteries do not have to have prizes that are cash (or cash equivalents) to be enticing for people. Prizes can be non-monetary rewards such as trips or sample products.
