Temple Grandin is the world expert at leading cattle, pigs, and lambs to the slaughter. She is also the world's most famous person diagnosed with autism. She holds that most unautistic people think mostly in words but that animals and autists think in pictures. Hence she knows, for example, what really scares animals and how to diminish their fear.
Cattle in the queue to be killed know perfectly well (this is me speaking for a moment) that something awful is just around the corner. So Grandin walks or crawls along the deadly corridor to notice, from an animal's eye, what cues lurk and redesigns the plant accordingly. By the time she has explained it to us, it is quite clear why a shadow or shape or light is terrifying, but apparently it took her to think about things from the animal's point of view. Most slaughterhouses in North America have learned from her. Her simple rule of thumb is that if more than a quarter of the cattle need to be electrically goaded, then something is wrong. Since a really upset steer causes as much loss of time, production, and cash as a fit of epilepsy on an old-time assembly line, meatpackers have taken her advice and continue to ask for it. Incidentally, she is not in favor of eating animals; she realistically believes that we will go on eating them, so we'd better make our killing more "humane."
The book expresses Grandin's distilled wisdom about animals, autism, and people. It does so with an unusual mix of hundreds of anecdotes and lots of citations of recent papers on neurology and on animal behavior—the two genres often being run together in the same paragraph. The citations and anecdotes reel on, hand in hand. Notice something remarkable here: a primary ground for diagnosing people as autistic is that they have great difficulty socializing and understanding other people. Grandin is a massive counterexample: she tells so many stories about her friends, acquaintances, and their beasts that one feels she is the most networked person in the world. And of course she had to have enormous powers of persuasion to change the men who run the abattoirs.
Her vision of the minds and brains of animals casts current folklore about regions of the brain and what they do into simple, digestible form. In her chapter on animal aggression, we learn that there are two types of aggression, located in different parts of a mammal's head, namely the predatory and affective types: "Humans have a tendency to mix up these two states, because the outcome is the same: a smaller, weaker animal ends up dead. But predatory aggression and rage aggression couldn't be more different for the aggressor." There are seven types of affective aggression ("Dogs have an inborn guard against excessive aggression called bite inhibition"). On the front cover of this National Bestseller, Entertainment Weekly is quoted: "At once hilarious, fascinating, and just plain weird, Animals is one of those rare books that elicit a 'wow' on every page."
Is she right about how animals and autists think? Her ideas are suggestive, to be reflected on and investigated. She certainly has the credentials, as someone who has arisen from a dreadful disability to change the world far more effectively than, I suspect, any reader of Common Knowledge. The style will put off a lot of those selfsame readers, but there are important assertions to dwell on. On the first page of the concluding "Behavior and Training Troubleshooting Guide," we read a summary of a doctrine urged throughout the book: "A basic principle of animal behavior is that WHO you have sex with, WHAT you eat, WHERE you eat, WHO you fight with, and WHO you socialize with are learned." That is a happy antidote to the neurological and genetic determinism that fills the pages of today's scientific folklore.
