I am "lifting" this article in its entirety. It was written by Kevin Dutton - but I can't tell you any more than that. Happy to rectify if advised. (Thanks & sorry Kevin.)
Q. Why do you say that babies are the best persuaders in the world?
A: Think about it. On our very first day on the planet, the influence task that faced us was immense. We had to persuade those around us, without language, without consciousness, without anything like the oratorical prowess that we possess as adults, to take care of us—to subjugate their own interests at the expense of ours. And we did it. Otherwise, we wouldn’t be here talking about it!
How? Well, certainly not through any provision of our own. If we’d had anything to do with it, we’d almost certainly have blown it! Instead, natural selection took care of things for us by equipping us with three features, fitted as standard, fiendishly calibrated to cut straight through our ozone layer of deliberation, to go pounding up the slippery steps of consciousness, and to hammer unrelentingly on the secret emotional chambers of our heart, which are:
1. A virtually unignorable soundtrack that figures at the top of nearly everyone’s list of aversive acoustic stimuli;
2. appallingly cute good looks, that prove pretty much irresistible to anyone caught in the spotlight;
3. and a hard-wired propensity to make eye-contact, to attend to the eye-regions of faces.
And boy, do these features work. In one study, a bunch of wallets were left on the streets of Edinburgh, each containing one of four photographs. A happy family. A cute puppy. An elderly couple. And a smiling baby. Which ones, the researchers wondered, would find their way back to their "owners" most often?
There was no doubting the answer.
Of the 40 wallets of each type that were dropped, 28% of those containing the portrait of the elderly couple made it back successfully; 48%, the family snapshot; 53%, the photo of the cute puppy.
And a whopping 88%, the picture of the smiling baby!
