This is no way to do science

A quote from Karl H Pribram, The Form Within: My Point of View

p. 386 “As an example in the 1950s, Clark Hull, professor of psychology at Yale University, tried to build an efficient causal input-output, behaviorist theory that would encompass the works of Pavlov, Freud and Thorndike. Hull developed equations in which the terms of the equations represented the results obtained from experiments and observation. He copied his approach from engineers, who are often faced with situations when an input and an output are know, but the experimenter has to determine what the intervening factors might be. Hull’s equations provided room for unknowns that would be found through further experimentation. This approach brought Hull a great following, and experiments on rats were performed in profusion at a great number of universities. Each finding generated yet another equation until, at last, the whole structure fell of its own weight. About a month before Hull died, he said to me in discouragement, ‘Karl, this is no way to do science.'”
