From The Economist:
A group of scientists has discovered that women are attracted to men who are fond of children. In years gone by, that announcement might have qualified for one of the late Senator William Proxmire’s Golden Fleece awards for pointless scientific research—except that what this particular group of scientists has shown is that women can tell who is and is not fond of children just by looking at their faces.
The members of the group in question, led by James Roney of the University of California, Santa Barbara, are part of the revival of a science that once dared not speak its name—physiognomy. In the late 18th century, and during most of the 19th, it was believed that the shape of a person’s head could tell you something about his character. Such deterministic thoughts fell out of favour during the 20th century. Most behavioural scientists thought that environment, not biology, shaped behaviour, and even those who did not could not see how the shape of the head or features of the face could possibly be relevant. What Dr Roney and his colleagues have found is that they are.
