(London Telegraph) Reporters from Reader’s Digest, the US consumer magazine, dropped wallets at various locations – from parks to shopping centres – in major cities around the globe, to see whether those residents that recovered them would attempt to contact the owner.

Each wallet contained around £30 in local currency, a mobile number, business cards, and a family photo.

In total, nearly half (47 per cent) of wallets were returned, but that figure varied wildly among the different cities involved in the study.
