The DSM-V Project: Bad Science Produces Bad Psychiatry
The project to develop the successor to fourth edition of the Diagnostic and Statistical Manual of Mental Disorders has been under way for 10 years, yet it is still several years from completion, and the field trials, the most difficult and expensive part, have not even started. This article explores the reasons why the project is struggling, arguing that the defects the Diagnostic and Statistical Model-V (DSM-V) Committee has found are not chance or random problems that can be overcome by more money but rather represent serious conceptual errors in the very basis of the ideas underlying the project. As a result of these errors, it is predicted that the entire notion of valid categories of mental disorder will collapse in self-contradiction. One of the most recent suggestions for a new disorder, psychotic risk syndrome (now APSS), is used to demonstrate how the principles of science cannot accommodate the unstated ideological demands driving the DSM-V project.
