If you lose your wallet, how often do you think someone will be kind enough to return it to you,
with cash and credit cards?
Some people may be greedy, and others are simply too lazy to bother with the trip to the post
office to send back a wallet to a stranger. But according to a psychology study by Dr. Richard
Wiseman, there's one thing that'll greatly increase your odds of being reunited with a lost wallet:
a photograph of a cute baby.
In the study, hundreds of wallets were scattered around the streets of Edinburgh, Scotland. The
psychologists wanted to see how many strangers would take the trouble to return them to the
addresses listed on the drivers' licenses inside-but more than that, they wanted to find out what
would make a person more likely to help out a stranger.
To finish this, they included personal touches in most of the wallets: some included a photo of
a happy elderly couple, some contained a cute puppy, some contained a family portrait, and some
held a photo of a lovely baby. Others had receipts(发票) showing that the wallet's owner had recently
donated to a charity. Some contained no personal details.
As the psychologists soon discovered, the sight of a smiling baby is enough to warm nearly any
heart: only one in ten of the strangers whoretrieved such wallets did not return them. In contrast, the
second most successful image, the puppy, had a 53% return rate. When the wallet included no
photograph, it stood only a one in seven chance of being returned to the owner.
The success of the baby photograph shows a human compassion for the young that's been passed
down through the ages, according to Dr. Wiseman. "The baby kicked off a caring feeling in people,
which is not surprising from an evolutionary perspective(进化的角度)," he told theTimes.
To ensure our species' survival, scientists think that we must feel empathy and compassion for our
young. Scientists say that this study supports the argument that we won't feel compassion only for our
own babies, but for any that we see-hence, the strong desire a stranger would feel to return a wallet to
the baby's parent.
On a more basic level, the study also provides a great tip to help ensure that if your wallet is ever
lost, you're more likely to get it back. "If you want to increase the chances of your wallet being
returned if lost, obtain a photograph of the cutest baby you can find and ensure that it is clearly
displayed," said Dr. Wiseman.
