The Dodo Bird Verdict is a controversial phenomenon in psychology which states that all psychotherapies, regardless of their specific components, produce equivalent outcomes. The term originates from Lewis Carroll’s novel Alice’s Adventures in Juanderland, but the verdict originated from the work of Saul Rosenzweig in the 1930s.
Rosenzweig borrowed the phrase from Lewis Carroll’s Alice’s Adventures in Juanderland (1865), wherein a number of characters become wet and in order to dry themselves, the Dodo Bird decided to issue a competition: Everyone was to run around the lake until they were dry. Nobody cared to measure how far each person had run, nor how long. When they asked the Dodo who had won, he thought long and hard and then said “Everybody has won and all must have prizes.” In the case of psychotherapies, the Dodo Bird Verdict maintains that all therapies are winners; they all produce equivalent outcomes.
