Today I would not recommend psychoanalysis to 99 percent of my patients in either the office or psychiatric hospital. Yet the tool of psychoanalytic thinking and the self-understanding it provides are as relevant as the prescription pad I carry. The fault is not with the patients or with the method because of the difficulty of submitting psychoanalysis to research scrutiny or validation. Many theories of modern physics were at first untestable because of limitations of technology. Therefore, regretfully, we fall back on "anecdotal reports," which are perhaps the only scientific instrument so far with any power in psychoanalysis. Yet, this mode of testing is not recognized as useful in contrast to current double-blind, controlled methods that are used when we deal with limited variables in clinical trials.
