I’m a great fan of Professor Jerome Kagan, the eminent Harvard psychologist, who has done important work on the role of the amygdala in emotional disorders like social anxiety. I admire his humane appreciation for both the sciences and the humanities, and his awareness of psychology and psychiatry’s dangerous tendency to ignore the role of culture, values, language and context in human emotional experience.
Kagan, considered one of the finest psychologists ever, is clearly deeply concerned about the direction of western intellectual life, and in particular about “the dramatic ascent of the natural sciences in the years following World War 2, which intimidated the other two scholarly communities” – ie the social sciences and the humanities. He feels we in the West have become out of balance, overly fixated on a biologically materialist view of the human condition, with serious consequences for our societies.
He expresses his concerns about our culture’s tendency to simplistic scientific materialism in his new book, Psychology’s Ghosts, which he discussed last month on Radio Boston. He said that psychology and psychiatry focus too much on the symptoms of emotional problems, while ignoring the causes – and, in particular, ignoring the cause of poverty:
If you think about all the physical diseases, they are diagnosed not by the symptoms you tell your doctor, but by the cause. Malaria means not that you have a fever but that you have the malarial parasite. Psychiatry is the only sub-discipline in medicine where the diagnoses are only based on the symptoms. You tell your doctor you can’t sleep and you have no energy and he says that you’re depressed. You’re treated for depression on the basis of your symptoms when your depression could come on for a half a dozen different reasons and the reasons are important in how you treat the patient.
There is inadequate research being done on the life history causes. In medicine, if you have a disease, immediately several hundred or a thousand investigators start at once — take AIDS — to find out what was the cause. There is very little research going on on the role of class, on the role of life history, on the role of who you identified with, your religious identification, your ethnic identification. In other words, there’s a whole complex set of causes; they are not being studied.
The problem is that biology made extraordinary advances, both in genetics and in ways to measure the brain. Because that technology is available, people rushed over to that side and hoped that that would solve the problem, abandoning the other half. To put it briefly, biology says you’re likely to be vulnerable to this envelope of illnesses. Your environment, your setting, your class, your culture, where you live disposes and selects from that envelope the symptoms you might develop.
As I read the literature, and I have many people on my side — the best predictor today in Europe or North America of who will be depressed is not a gene and it’s not a measure of your brain; it’s whether you’re poor. And that makes sense.
If, in a country like ours with an enormous range of income, you’re poor and you’ve been poor since you were a child, which means that your medical care is less adequate, your diet’s less adequate, you’re probably fighting some low level infections and you’re poor — that’s a pretty good reason to be depressed.
That then is taken out because we’re looking for the genes. Now, in fact, there probably is 10 percent of depressed who do have a specific genetic vulnerability and then we’re missing the 80 percent who don’t have a specific genetic vulnerability — they have a very good reason for being depressed […]
We’re hoping that we will discover the biological causes and treat the biological causes and we won’t have to worry about the societal causes and the individual lifestyle circumstances that people deal with. That’s the hope. My own view — and I’m not alone — is that is denying the problem.
