.        A social worker invents a new therapy that brings her fame, fortune, and a large following of professional disciples. Two studies evaluate her new therapy. One is scientifically weak in its design, and concludes that her therapy is extremely effective. The other is scientifically very strong in its design, but concludes that her therapy is not effective at all. She writes a letter to the journal publishing both studies. In her letter she severely criticizes the design of the strong study (and therefore also criticizes the credibility of its findings), and she praises the design and findings of the weak study.
