The term "evidence-based" therapy has become a de facto code word for manualized therapy, most often brief, highly scripted forms of cognitive behavior therapy. It is widely asserted that "evidence-based" therapies are scientifically proven and superior to other forms of psychotherapy. Empirical research does not support these claims, but shows that "evidence-based" therapies are weak treatments. Their benefits are trivial, few patients get well, and even the trivial benefits do not last. Troubling research practices paint a misleading picture of the actual benefits of "evidence-based" therapies, including sham control groups, cherry-picked patient samples, and suppression of negative findings.
