Baby photos could help to get a lost wallet returned

From a Times Online article about a study by psychologist Richard Wiseman who »lost« a few hundred wallets with different or no pictures in them:

When faced with the photograph of the baby people were far more likely to send the wallet back, the study found. In fact, only one in ten were hard-hearted enough not to do so. With no picture to tug at the emotions, just one in seven were sent back.
