As shown in the graph, the yellow dot symbolizes the percentage of wallets without any in money in them that were returned, and the red dot shows the percentage of returned wallets that contained money inside them. Scandinavian countries aced the experiment by returning the biggest amount of lost wallets. Unfortunately, countries like China, Morocco, Peru, and Kazakhstan had the smallest return-rate.There were a few factors that affected the way people responded to the lost wallet – researchers found that wallets that had a key were returned way more often than those without the key, which mainly has to do with people thinking the key has a more significant value to the owner.
