What is radical in radical behaviorism? A private plunge in historical events

Some instances of behavior are private or covert, meaning they are accessible to only the behaving person, and a naturalistic science of behavior has to use the same terms and concepts as behavior accessible for others. Skinner’s discussion of the distinction between radical and methodological behaviorism focuses on privately observable behavior. Radical behaviorism does not distinguish between observational and theoretical terms in the same way as traditional psychology, and there is no need for the ghost in the machine used by methodological behaviorists. In both experimental and applied behavior analysis, private events should be important, but why and when has so many lost their way? Don’t expect the question to be completely answered during this presentation.
