Author J.R.R Tolkien advises, “there is nothing like looking, if you want to find something.” Through most of the last century psychology looked for a way to explain learning in a scientific way.  Researchers found lots of ways to describe learning, but never a truly scientific way to explain it. Oddly, the truth was right in front of them. But they didn't see because they had decided in advance to ignore it. They were looking with their eyes shut. Frustrated, they finally abandoned their quest, turning their attention to other things. That’s too bad, because if we understood normal habits, we could understand abnormal habits such as addictions. Can we see what those researchers didn’t see? Certainly. But we do have to look with our eyes open.
