Perceptions of Animals




Dr. Frans de Waal

By Frans de Waal, Ph.D.



Frans de Waal is the Charles Howard Candler Professor of Primate Behavior at Emory University and the Director of the Living Links Center at the Yerkes National Primate Research Center. He is also a member of the United States National Academy of Sciences and the Royal Netherlands Academy of Sciences and a member of the AJOB Neuroscience editorial board. His research focuses on primate social behavior, including conflict resolution, cooperation, inequality aversion, and food-sharing. 





At a recent workshop on
"Beastly Morality" (April 5, 2013, Emory Ethics Center), which drew
participants from all over the country, I asked an innocent question. We
had about sixty scholars presenting or listening to academic papers on
the human-animal relationship or the place of animals in literature, and
I asked how many of them worked with animals on a daily basis. The
answer: no one.




It was a naive question, because if I had
expected half of them to say that they did work with animals, these same
academics would probably be writing on something totally different,
such as the behavior of animals, their treatment by us, or their
intelligence. That's what I do, being a scientist. We rarely write about
anything that cannot be observed or measured, and so we assume it must
be the same for everybody else. But if one's focus is how Thomas Aquinas
viewed animals, the definition of personhood, or the moral status of
animals in Medieval Japan -- all of which were topics at the workshop --
first-hand knowledge of animals is hardly required.



Undeniably, there is a dearth of exchange between scientists and other
academics on the issue of animals, the reason being that for scientists
the animal is a concrete study object, whereas for scholars in English
departments or other corners of the humanities, the animal often is an
abstract entity judged by its place in literature, its perception in
history, its role in religion, or its relation to human self-identity.
Are we animals? Positions seem to be gradually shifting in this
direction, but none of this relates much to the essence of the animal
itself, even less to any specific species, such as our closest
relatives, the anthropoid apes.



On the other hand, it would
be naive for scientists to think that how we study animals is free from
cultural biases. It is impossible for us to break away from human
perceptions. There is a reason, for example, why treatment of animals as
individuals by giving them names and following their lives over time --
a common technique today -- is not a Western invention. Lacking souls,
animals were traditionally viewed as all the same. European ethologists
kept talking about species-typical behavior, and American behaviorists
did not even appreciate that species might differ. B. F. Skinner bluntly
said: “Pigeon, rat, monkey, which is which? It doesn’t matter” (Bailey,
1986).








There was enormous resistance, therefore, to the
personalization of animals, so much so that when Kinji Imanishi, the
father of Japanese primatology, visited American universities in 1958 to
explain how his students recognized a hundred different monkeys in each
troop, he only met raised eyebrows. His audience felt that doing so was
an impossibility (de Waal, 2001). The first to recognize the potential
of the Japanese approach was Ray Carpenter, an American primatologist.
Carpenter himself identified individuals by means of tattoos, hence with
an initial underestimation - typical for Western science - of their
individuality. It would be a bit like me going to a party and putting
colored dots on everyone’s foreheads saying that otherwise I couldn’t
tell these people apart. It is obvious, however, that Carpenter was an
astute observer. When he first heard of the Japanese studies, he did not
share the skepticism of his colleagues, who reacted with disbelief that
monkeys could be distinguished just from sight. They viewed all this
naming of individuals as hopelessly anthropomorphic, which at that time
was about the most damning label one could come up with. Animals were
supposed to be different. They wondered if the Japanese were not grossly
overestimating the social lives of their monkeys. Who said that monkeys
could tell each other apart even if human observers said that they
could? Even though the Japanese approach has now won many converts, I
call it a "silent invasion" given how reluctant Westerners have been to
recognize Imanishi's priority and influence (de Waal, 2003).

Clearly, the way we perceive animals affects how we conduct science.
There is every reason for scientists to listen to exposés on the
cultural views of animals, just as there is every reason for anyone
writing on animal representations to investigate what science actually
knows about the species in question. This way, both groups may come
together and have a more fruitful exchange than we have had thus far.

Parental care of rodents is not the same as socioeconomic status in humans.

The question of socioeconomic status in scientific research is an interesting one. Many experiments do not take socioeconomic status into account, yet studies show that socioeconomic status can significantly alter the human brain. The article, “Socioeconomic status and the brain: mechanistic insights from human and animal research” addresses some of these issues. However, one of the main problems I noticed with this article is the equivalence of socioeconomic status with quality of parental care. The article seems to associate lower socioeconomic status with parental neglect. Conversely, higher socioeconomic status is associated with higher quality parental care. While there may in fact be a correlation, status is by no means a perfect predictor of parental quality.







Parental care in rats (source)





One of the studies cited in the article uses lack of grooming in rats as a model for low socioeconomic status based on the idea that parental care is equated to status. However, this model shows no more than the effects of early life stress and parental neglect. It would not be appropriate to extend this to make conclusions about socioeconomic status. For one thing, rats do not have a social hierarchy, and without the concept of social status one should not draw conclusions.




Even primates with clearly defined social hierarchies do not innately have a concept of economy. It would be interesting to extend this study into nonhuman primates, but it would be necessary to introduce the concept of money into the system. A similar construct has been demonstrated by Keith Chen and Laurie Santos of Yale University. These researchers trained a group of capuchin monkeys to use money as a means of exchange. Aside from observing the first nonhuman prostitute, they showed that species other than humans can be taught the concept of money. If one were to combine this technique with a species that has a well defined, complex social hierarchy, say the Rhesus macaque, then you would truly have an animal model of socioeconomic status. Basically, rats aren’t cutting it.
