To Steve Hyman, the manual that clinicians currently use to diagnose mental disorders is an active obstacle to getting a scientific understanding of those disorders. Hyman, who is director of the Stanley Center for Psychiatric Research at the Broad Institute, MIT and Harvard, and a former director of the National Institute of Mental Health (NIMH), listed multiple weaknesses of the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders (DSM), whose diagnoses, he said, are “arbitrary, rigid, life-stage and context-insensitive,” as well as blind to the fact that mental disorders exist along a continuum.
