On January 4, 2016, the B. F. Skinner Foundation launched a new project – Skinner’s Quote of the Day. Quotes from B. F. Skinner’s works, selected by renowned scientists, appear daily Monday-Friday in order, starting with Chapter 1 of each book and running all the way through the last chapter. We started with the Science and Human Behavior (January-December 2916), followed by About Behaviorism (January-November 2017), Contingencies of Reinforcement (January-October 2018), Recent Issues (October 2018-May 2019), Reflections on Behaviorism and Society (May 2019-February 2020), and now moving on to Upon Further Reflection (from February 10 2020).

"The manipulation of independent variables appears to be circumvented when, instead of exposing an organism to a set of contingencies, the contingencies are simply described in “instructions.” . . .…
"Statistical techniques often inject a destructive delay between the conduct of an experiment and the discovery of the significance of the data—a fatal violation of a fundamental principle of reinforcement."…
"Operant methods make their own use of Grand Numbers; instead of studying a thousand rats for one hour each, or a hundred rats for ten hours each, the investigator is…
"The complex system we call an organism has an elaborate and largely unknown history which endows it with a certain individuality . . . Statistical techniques cannot eliminate this kind…
"Eventually the investigator may move on to peripheral areas where indirect methods become necessary, but until then he must forego the prestige which attaches to traditional statistical methods." (p. 111)…
"When a variable is changed and the effect on performance observed, it is for most purposes idle to prove statistically that a change has indeed occurred. (It is sometimes said…
"The effect [of studying changes in rate of responding on a cumulative recorder] is similar to increasing the resolving power of a microscope; a new subject matter is suddenly open…
"The term “operant” distinguishes between reflexes and responses which operate directly on the environment . . . . The alternative term, instrumental, suggests the use of tools. To say that…
"The consequences of action change the organism regardless of how or why they follow. The connection need not be functional or organic—as, indeed, it was not in Thorndike’s experiment." (p.…
"The teleological problem is, of course, not solved until we have answered certain questions: what gives an action its purpose, what leads an organism to expect to have an effect,…
"Some effects seem to throw light on the behavior which produces them, but their explanatory role has been clouded by the fact that they follow the behavior and therefore raise…
"We ignore some things for the sake of studying others, but we do not ignore them permanently. They will be studied in their turn." (p. 103) Subscribe to RSS…
"The experimental analysis of behavior is, of course, an analysis. The environment in which human behavior is observed is usually simplified so that one aspect (or at most a very…
"Although it is sometimes said that research on lower animals makes it impossible to discover what is distinctly human, it is only by studying the behavior of lower animals that…
"In both [geophysics and the experimental analysis of behavior], principles derived from research conducted under the favorable conditions of the laboratory are used to give a plausible account of facts…
"The use of concepts and laws derived from an experimental analysis in the interpretation of daily life is also a source of misunderstanding. An analogy from another science may be…
"An experimental analysis of behavior is necessarily a science in progress. The assertion that it cannot explain some aspect of behavior must be qualified with the phrase “as of this…
"Man may be foolish enough to set off a nuclear holocaust—not by design but by one of those accidents which are so much admired by those who oppose design." (p.…
"The need for an effective technology of behavior is obvious enough. Every generation seems to believe that the world is going to the dogs, but (to be ethological for a…
"In the long run, the effective management of human affairs will probably require a change in the way in which everyone thinks about himself and those with whom he comes…
"The scientific method which has made [the experimental analysis of behavior] successful in the laboratory makes it almost immediately available for practical purposes. It is not concerned with testing theories…
"Psychology as a basic science has failed to supply a conception which recommends itself to specialists in other fields of human behavior." (p. 96) Subscribe to RSS feed here
"When Freud first turned from biology to psychology, he wrote to a friend: “What horrifies me more than anything else is all the psychology I shall have to read in…
"The psychological literature contains a prodigious number of charts, graphs, tables, and equations reporting quantitative relations among unimportant or useless variables. Much of this may be attributed to professional contingencies…
"Behavior as a dependent variable is often neglected when the investigator turns his attention to internal processes, real or fancied." (p. 92) Subscribe to RSS feed here
"An emphasis on topography of behavior at the expense of controlling relations is an example of the Formalistic Fallacy. It is common in linguistics and psycholinguistics." (p. 89) Subscribe…
"An operant must behave like one; it must undergo orderly changes in probability when independent variables are manipulated." (p. 89) Subscribe to RSS feed here
"Controllable variables are . . . lacking when behavior is predicted from other behavior. The tests used in mental measurement evoke samples of behavior from which characteristics of similar behavior,…
"Uncontrollable independent variables. The ethologists study behavior as a function of species status. A graylag goose behaves in a given way because it is a graylag goose. To change the…
"[Bixenstine] suggests that the optimism [in all behavior science] springs from release from the anxiety of theory construction. There is a more obvious explanation: the analysis works." (p. 86) …
"Patience with respect to unexplored parts of a field is particularly important in a science of behavior because, as part of our own subject matter, we may be overwhelmed by…
". . . a smooth curve showing a change in probability of a response as a function of a controlled variable is a fact in the bag, and there is…
"In addition to the systematic manipulation of contingencies, the interpretation of human affairs is a rich source of suggestions for experiments. Do conditions detected in some episode in daily life…
"A study of schedules of reinforcement . . . can proceed in a rather Baconian fashion, . . . the “theory,” if any, being concerned with what organisms will do…
"The experimental control of variables is emphasized rather than a later evaluation of their presumed importance through statistical analyses. The number of organisms studied is usually much smaller than in…
"[In the experimental analysis of behavior,] relations among dependent and independent variables are seldom explored according to a prior “experimental design,” as R. A. Fisher used that term. The null…
"Describing a set of contingencies in instructions to the subject is no substitute for exposing the subject to the contingencies, particularly when they need to be programmed." (p. 80) …
"One task of an experimental analysis is to discover all the variables of which probability of response is a function." (p.78) Subscribe to RSS feed here
"Rate of responding is a basic dimension, not simply because responses can be accurately counted, but because rate is relevant to the central concern of a science of behavior." (p.…
"To discriminate is not to respond but to respond differently to two or more stimuli." (p. 76) Subscribe to RSS feed here
"Like probability, rate of responding would be a meaningless concept if it were not possible to specify topography of response in such a way that separate instances of an operant…
"A natural datum in a science of behavior is the probability that a given bit of behavior will occur at a given time. An experimental analysis deals with that probability…
"[According to cultural norms] . . . innocent activities like card playing or dancing or simply doing nothing should certainly be left to the individual. But the question is: Can they…
"It simply happens that when the environment has been altered so that major reinforcers are no longer powerful, lesser reinforcers take over." (p. 68) Subscribe to RSS feed here
"Money is the archetypal generalized reinforcer, and men are reinforced by it even when they do not exchange it for other things. The possibility of a generalized negative reinforcement must…
"The trouble with both affluent and welfare societies is that reinforcers are not contingent on behavior. Men who are not reinforced for doing anything do little or nothing . .…
"For more than two hundred years talented and skillful men have worked to create a device which will powerfully reinforce the behavior of pressing keys. (The piano, is, indeed, an…
