This is an argument with which I am familiar but this is one of the clearest and most concise articles on the matter that I have read. I have long felt that psychology is, in general, a more scientific pursuit than psychiatry. That coupled with the fact that psychiatrists are doctors who specialise in mental health, whereas until recently clinical psychologists had to acquire a research PhD, which I feel gives them an appreciation for what genuinely valid scientific research consists of. As a hobby I am a bit of an amateur futurologist, I like to imagine and predict how the advances in science and technology will affect us and the world we live in, in the future. One of my hopes is that with the continuing advancement in technology relating to brain imaging we will reach a point where neuroscience and neuroimaging will be able able to identify when there is an underlying organic disease state in a mental illness (whether generally for that illness or personally for that individual) and in this instance treat the disease with whichever medical procedures we deem appropriate. And in the instance when we can’t identify a disease state, as presumably the symptoms are a manifestation of social, psychological and behavioural problems, we will be able to employ scientifically verified psychological techniques. I am not sure where this will leave psychiatrists and psychiatry as a profession, but I suspect it will evolve to fill a new niche.
