We all know the scene: the departmental coffee room, with the price list for tea and coffee on the wall and the “honesty box” where you pay for your drinks – or not, because no one is watching.

In a finding that will have office managers everywhere scurrying for the photocopier, researchers have discovered that merely a picture of watching eyes nearly trebled the amount of money put in the box.

The faces varied but the eyes always looked directly at the observer.
