Think of all the nonsense you had to learn in psychology courses. None of which was testable. None of which was measurable. We had behaviorism, Freudian psychology, all of these theories that you learn in psychology. Totally untestable. Now, we can test it, because physics allows us to calculate energy flows in the brain.
If we ever do end up acting just like rats or Pavlov's dogs, it will be largely because behaviorism has conditioned us to do so.
The Legacy of Behaviorism: Do this and you'll get that.
