Linking the name of John B. Watson to Methodological Behaviorism or to dualism has been a common and indiscriminate practice in the Brazilian literature of psychology. This paper aims to identify possible sources of control for this binding. It was found that the spread of the idea of Watson being a dualistic or a methodological behaviorist may be related to (A) Watson's reluctance to define his ontological commitments in his early writings, (B) the writing style of B. F. Skinner, who criticized the Methodological Behaviorism without specifying who are the methodological behaviorists, and (C) the influence of Matos' (1997a) text. It is suggested that a return to the original texts of Watson is necessary for the proper characterization of his work and an understanding of the history of the behaviorist movement.
