"I have nothing to say"
Burrhus Frederic (B.F.) Skinner majored in literature at Hamilton College in New York. He went to New York City in the late 1920s to become a writer, but he wasn't very successful. "I had nothing important to say," he later exlained. So he decided to go back to school, and went to Harvard to study psychology, since he had always enjoyed observing animal and human behavior. For the most part, the psychology department there was immersed in introspective psychology, and Skinner found himself more and more a behaviorist. He worked in the lab of an experimental biologist, however, and developed behavioral studies of rats. He had always been a tinkerer, and loved building Rube Goldberg contraptions as a kid; he put that skill to use by designing boxes to automatically reward behavior, such as depressing a lever, pushing a button, and so on. His devices were such an improvement on the existing equipment, they've come to be known as Skinner boxes. As Skinner became more and more frustrated about the fact that behaviorism wasn't having a large enough impact on psychology, he began devoting most of his time to answering the question of why behaviorism should be a science.
