Using lotteries to make us better people
Lotteries aren\u2019t just about winning money. They\u2019re also being used to nudge people to change their behaviour.
In the UK we try out a mobile app that enters users in to a \xa325,000 lottery every time they pick up a piece of litter.
We see how heart patients in the US can win smaller prizes for taking their pills\u2026 and if they don\u2019t take their medicine, are told what they could have won.
And we look at receipt lotteries, where customers are encouraged to get receipts as each one is an entry to a big monthly draw. The scheme started in Taiwan but has been replicated in a number of countries, helping governments find the businesses avoiding tax.
