Why People Love Their Pets
Social science has now explained, as if it needed explaining, why people love their pets.
John Archer, a psychologist at the , has been puzzling for some time over why people love their pets. In evolutionary terms, love for dogs and other pets “poses a problem,” he writes. Being attached to animals is not, strictly speaking, necessary for human health and welfare. True, studies show that people with pets live a bit longer and have better blood pressure than benighted nonowners, but in the literal sense, we don’t really need all those dogs and cats to survive.
Of course, we don’t need ice cream, coffee, sports, music, or a whole host of other pleasurable things to survive, either.
Archer suggests, “consider the possibility that pets are, in evolutionary terms, manipulating human responses, that they are the equivalent of social parasites.” Social parasites inject themselves into the social systems of other species and thrive there. Dogs are masters at that. They show a range of emotions—love, anxiety, curiosity—and thus trick us into thinking they possess the full range of human feelings.
They dance with joy when we come home, put their heads on our knees and stare longingly into our eyes. Ah, we think, at last, the love and loyalty we so richly deserve and so rarely receive. Over thousands of years of living with humans, dogs have become wily and transfixing sidekicks with the particularly appealing characteristic of being unable to speak. We are therefore free to fill in the blanks with what we need to hear. (What the dog may really be telling us, much of the time, is, “Feed me.”)
Plus, they’re cute and furry.
