" The issue is so important to us that it is almost funny. A colleague told me about this informal social psychological experiment: A new baby was left in a park with an attendant who, when asked by passersby, would claim to have agreed to sit with the child for a few moments and did not know if it was a boy or girl. Everyone stopping to admire the infant was quite distressed at not being able to know the child’s gender. Some even offered to undress the child to find out. Other studies explain why gender matters so much: people tend to treat baby boys and girls quite differently. "
