It was Watson who famously announced in 1913 the behaviorist point of view: "Psychology as the behaviorist views it is a purely objective experimental branch of natural science. Its theoretical goal is the prediction and control of behavior. Introspection forms no essential part of its methods.… The behaviorist… recognizes… no dividing line between man and brute." But Watson turned out to be as much showman as scientist, and Skinner bitterly criticizes his extreme claims and "shortage of facts" that cast lasting doubt on radical behaviorism.
