Burrhus Frederic Skinner

Burrhus Frederic Skinner (March 20, 1904 – August 18, 1990) was an American psychologist and author. He conducted pioneering work on experimental psychology and advocated behaviorism, which seeks to understand behavior as a function of environmental histories of reinforcement. He also wrote a number of controversial works in which he proposed the widespread use of psychological behavior modification techniques, primarily operant conditioning, in order to improve society and increase human happiness, as a form of social engineering.

Skinner was born in rural Susquehanna, Pennsylvania. He attended Hamilton College in New York with the intention of becoming a writer and received a B.A. in English literature in 1926. After graduation, he spent a year in Greenwich Village attempting to become a writer of fiction, but he soon became disillusioned with his literary skills and concluded that he had little world experience and no strong personal perspective from which to write. During this time, which Skinner later called "the dark year," he chanced upon a copy of Bertrand Russell's recently published book An Outline of Philosophy, in which Russell discusses the behaviorist philosophy of psychologist John B. Watson. At the time, Skinner had begun to take more interest in the actions and behaviors of those around him, and some of his short stories had taken a "psychological" slant. He decided to abandon literature and seek admission as a graduate student in psychology at Harvard University (which at the time was not regarded as a leading institution in that field).

Skinner received a Ph.D. from Harvard in 1931 and remained at that institution as a researcher until 1936. He then taught at the University of Minnesota at Minneapolis and later at Indiana University before returning to Harvard as a tenured professor in 1948. He remained there for the rest of his career.

Skinner was granted numerous awards in his lifetime. In 1968, he received the National Medal of Science by President Lyndon B. Johnson. Three years later, he was awarded the Gold Medal of the American Psychological Foundation, and in 1972, he was given the Humanist of the Year Award of the American Humanist Association. Just eight days before his death, he received the first Citation for Outstanding Lifetime Contribution to Psychology by the American Psychological Association (Epstein, 1997).

Behaviorism

Skinner was mainly responsible for the development of the philosophy of radical behaviorism and for the further development of applied behavior analysis, a branch of psychology which aims to develop a unified framework for animal and human behavior based on principles of learning. He conducted research on shaping behavior through positive and negative reinforcement and demonstrated operant conditioning, a behavior modification technique which he developed in contrast with classical conditioning.

Skinner did not advocate the use of punishment. His research suggested that punishment was an ineffective way of controlling behavior, leading generally to short-term behavior change, but resulting mostly in the subject attempting to avoid the punishing stimulus instead of avoiding the behavior that was causing punishment. A simple example of this is the failure of prison to eliminate criminal behavior. If prison (as a punishing stimulus) were effective at altering behavior, there would be no criminality, since the risk of imprisonment for criminal conduct is well established. However, individuals still commit offences, but attempt to avoid discovery and therefore punishment. The punishing stimulus does not stop criminal behaviour. The criminal simply becomes more sophisticated at avoiding the punishment. Reinforcement, both positive and negative (the latter of which is often confused with punishment), proves to be more effective in bringing about lasting changes in behaviour.

Superstition in the pigeon

One of Skinner 's most famous and interesting experiments examined the formation of superstition in one of his favorite experimental animals, the pigeon. Skinner placed a series of hungry pigeons in a cage attached to an automatic mechanism that delivered food to the pigeon "at regular intervals with no reference whatsoever to the bird's behavior". He discovered that the pigeons associated the delivery of the food with whatever chance actions they had been performing as it was delivered, and that they continued to perform the same actions:

One bird was conditioned to turn counter-clockwise about the cage, making two or three turns between reinforcements. Another repeatedly thrust its head into one of the upper corners of the cage. A third developed a 'tossing' response, as if placing its head beneath an invisible bar and lifting it repeatedly. Two birds developed a pendulum motion of the head and body, in which the head was extended forward and swung from right to left with a sharp movement followed by a somewhat slower return. ("'Superstition' in the Pigeon", B.F. Skinner, Journal of Experimental Psychology #38, 1947 [1])

Skinner suggested that the pigeons believed that they were influencing the automatic mechanism with their "rituals" and that the experiment also shed light on human behavior:

The experiment might be said to demonstrate a sort of superstition. The bird behaves as if there were a causal relation between its behavior and the presentation of food, although such a relation is lacking. There are many analogies in human behavior. Rituals for changing one's fortune at cards are good examples. A few accidental connections between a ritual and favorable consequences suffice to set up and maintain the behavior in spite of many unreinforced instances. The bowler who has released a ball down the alley but continues to behave as if she were controlling it by twisting and turning her arm and shoulder is another case in point. These behaviors have, of course, no real effect upon one's luck or upon a ball half way down an alley, just as in the present case the food would appear as often if the pigeon did nothing -- or, more strictly speaking, did something else. (Ibid.)

Modern behavioral psychologists have disputed Skinner's "superstition" explanation for the behaviors he recorded. Subsequent research (for instance, by Staddon and Simmelhag in 1971) failed to replicate his results. Eduardo J. Fernandez of the Department of Psychology of Indiana University sought to follow up on Staddon and Simmelhag's debunking of Skinner's hypothesis and to "further contrast superstitious versus functional interpretations of behavior" in pigeons. In a 2004 paper titled "Superstition Re-revisited: An Examination of Niche-Related Mechanisms Underlying Schedule Produced Behavior in Pigeons," he demonstrated that what Skinner had seen as "supersitious" behaviour was accounted for by the natural foraging behaviours of the species he used as test subjects.

Social engineering

Skinner is popularly known mainly for his controversial books Walden Two and Beyond Freedom and Dignity. Walden Two describes a visit to an imaginary utopian commune in the 1940s United States, where the productivity and happiness of the citizens is far in advance of that in the outside world due to their practice of scientific social planning and the use of operant conditioning in the raising of children.

Walden Two, like Thoreau's Walden, champions a lifestyle that does not support war or foster competition and social strife. It encourages a lifestyle of minimal consumption, rich social relationships, personal happiness, satisfying work and leisure.

Beyond Freedom and Dignity advanced the thesis that social concepts such as free will and human dignity (by which Skinner meant belief in individual autonomy) were obsolete, and stood in the way of greater human happiness and productivity. Skinner was opposed to inhumane treatment and bad government, but he argued that the champions of freedom went so far as to deny causality in human action so they could champion the "free person." In a sense, the champions of freedom were enemies of a scientific way of knowing. There is a rough parallel here to the book Higher Superstition in the identification of opponents to scientific knowledge, except Skinner here is being much more general in the opponents actually identified.

As understood by Skinner, ascribing dignity to individuals involves giving them credit for their actions. To say "Skinner is brilliant" means that Skinner is an originating force. If Skinner is right, he is merely the focus of his environment. He is not an originating force and he had no choice in saying the things he said or doing the things he did. Skinner's environment and genetics both allowed and compelled him to write his book (though this does not entail that the book's claims are untrue, which is a separate issue). Similarly, the environment and genetic potentials of the advocates of freedom and dignity cause them to resist the reality that their own activities are deterministically grounded.

Rumors

One often-repeated story claims that Skinner ventured into human experiments by raising his daughter Deborah in a Skinner box, which led to her life-long mental illness and a bitter resentment towards her father.

In fact, the Heir Conditioner, a term for Skinner's baby crib, was heated, cooled, had filtered air, allowed plenty of space to walk around in, and was much like a miniature version of a modern home. It was designed to make the baby more confident, more comfortable, less sick, less prone to cry, and so on. Reportedly it had some success in these goals.

In 2004, psychologist and author Lauren Slater published a book, Opening Skinner's Box, which mentioned claims that Deborah Skinner (now Deborah Skinner Buzan) unsuccessfully sued her father for abuse, and later committed suicide. In response, Buzan herself came forward to publicly denounce the story as nothing more than hearsay and presumably to vouch for her own continued existence. She blasted Lauren Slater's book for repeating this urban legend as being vicious and harmful. Farhad Manjoo, a writer for Salon.com, protested in a 2004 literary review that Buzan's Guardian article 'reads as if she has never even picked up Slater's book', observed that 'Slater's description of the box is pretty much in line with Buzan's description in the Guardian', and called the book 'a genuinely compelling read'.

Political Views

Skinner's political writings emphasized his hopes that an effective and humane science of behavioral control - a behavioral technology - could solve human problems which were not solved by earlier approaches or were actively aggravated by advances in physical technology such as the atomic bomb. One of Skinner's stated goals was to prevent humanity from destroying itself.

Skinner was sometimes accused of being a totalitarian by his critics. In addition to his aspirations to state design, Skinner was a determinist, believing that all of our behavior is profoundly determined and influenced by the environment.

Skinner saw the problems of political control not as a battle of domination versus freedom, but as choices of what kinds of control were used for what purposes. Skinner opposed the use of coercion, punishment and fear and supported the use of positive reinforcement.

Skinner's book Walden Two presents a vision of a decentralized, localized society which applies a practical, scientific approach and futuristically advanced behavioral expertise to peacefully deal with social problems. Skinner's utopia, like every other utopia or dystopia, is both a thought experiment and a rhetorical work.

Skinner answers a problem that exists in many utopian novels "What is the Good Life?" Skinner answers that it is a life of friendship, health, art, a healthy balance between work and leisure, a minimum of unpleasantness, and a feeling that one has made worthwhile contributions to one's society.

Additionally Skinner felt behavioral technology would offer alternatives to coercion, good science applied right would help society, and we would all be better off if we cooperated with each other peacefully. Skinner's novel has been described by Skinner as "my New Atlantis" referring to Bacon's utopia.

Intellectual opponents, such as Noam Chomsky, in their attempt to show Skinner wrong, have equated Skinner's philosophic determinism with political oppression. Skinner has often been equated to political and social positions he never espoused and even explicitly objected to.

Trivia

According to a photo caption at the site of Los Horcones community (which was inspired by Skinner's Walden Two), in his youth Skinner used to swim in Thoreau's Walden Pond.

The show Lost mentions Skinner, and its plot may resemble social engineering.
