Bests & Worsts Reviews from Amazon

There is (yet another) fight raging in science. This one is over how we evaluate other vertebrates. In this fascinating and eye-opening compendium, Frans de Waal says we are prejudiced towards ourselves, always comparing animals’ performance to ours, in unfairly biased experiments designed for us. It bothers people that we are not unique, and it bothers de Waal that animals don’t get the credit they deserve. Ranging all over the world and all over species, the book is an endless marvel. de Waal gives the example of a chimp named Ayumu at a research center in Japan, who can routinely memorize nine numbers in any given order, having seen them for just one fifth of one second. He can then pick them out in order from random numbers presented to him all over the computer screen. No human comes close. That’s a problem for a lot of scientists. The book is full of examples of animals, birds and fish doing highly intelligent things naturally. Our tests twist and pervert their skills to fit the test, showing them less intelligent than they are. We draw the wrong conclusions, often by asking the wrong questions. de Waal shows the way to a far more appreciative and objective way of looking at the world. My own favorite story in prejudice occurred when scientists induced pain in the feet of mice to see if they could be made to hide it. They found that mice could put on a brave face, but only when a human male tended to them. For females, they let their guard down; they freely showed their suffering. The difference was so strong that it worked even when scientists simply placed a man’s t-shirt near the cage. The mice were totally focused on fear and ignored their own pain. This said two things: mice could hide their own pain, and every experiment using mice is to some extent invalid, prejudiced by the mere presence of humans. Male or female scientists will cause different results. To that story, de Waal adds attention, motivation, and especially cognition, giving animals the full range of unlimited possibility, including communication (bottlenose dolphins call to each other by name). It is actually true respect. Possibly the most telling sentence about primates (de Waal’s focus) is that the caretakers in a primate center have greater respect for the intelligence of the animals than do the psychologists and philosophers who run the experiments. Every being is magnificently adapted to its habitat and needs. That they have different strengths, some or none of which might also be present in humans, is basically irrelevant. The whole field of comparative psychology, where we test how animals measure up to humans, is irrelevant and invalid. We need to appreciate the possible, not the comparative. David Wineberg
