“Today’s psychotherapy students are exposed to too much emphasis on diagnosis. Managed-care administrators demand that therapists arrive quickly at a precise diagnosis and then proceed upon a course of brief, focused therapy that matches that particular diagnosis. Sounds good. Sounds logical and efficient. But it has precious little to do with reality. It represents instead an illusory attempt to legislate scientific precision into being when it is neither possible nor desirable.” (Irvin D. Yalom, in “The Gift of Therapy”)
