Tricking people into doing things

I recently read an article about a successful program to help smokers quit:

Committed Action to Reduce and End Smoking is a savings program offered by the Green Bank of Caraga in Mindanao, Philippines. A would-be nonsmoker opens an account with a minimum balance of one dollar. For six months, the client deposits the amount of money she would otherwise spend on cigarettes into the account. After six months, the client takes a urine test to confirm that she has not smoked recently. If she passes the test, she gets her money back. If she fails the test, the account is closed and the money is donated to a charity. MIT’s Poverty Action Lab found that opening up an account makes those who want to quit 53 percent more likely to achieve their goal. No other antismoking tactic, not even the nicotine patch, appears to be so successful.

Great Idea!
