Nicholas Bakalar in the New York Times:
Researchers at the University of Alberta carefully observed how parents treated their children during trips to the supermarket. They found that physical attractiveness made a big difference.
The researchers noted if the parents belted their youngsters into the grocery cart seat, how often the parents’ attention lapsed and the number of times the children were allowed to engage in potentially dangerous activities like standing up in the shopping cart. They also rated each child’s physical attractiveness on a 10-point scale.
