In 1957 American psychologist Albert Ellis, though he did not know it yet, would aid cognitive therapy in correcting cognitive distortions and indirectly helping David D. Burns in writing "The Feeling Good Handbook". Ellis created what he called the ABC Technique of rational beliefs. The ABC stands for the activating event, beliefs that are irrational, and the consequences that come from the belief. Ellis wanted to prove that the activating event is not what caused the emotional behavior or the consequences, but the beliefs and how the person irrationally perceive the events that aids the consequences. With this model, Ellis attempted to use rational emotive behavior therapy (REBT) with his patients, in order to help them "reframe" or reinterpret the experience in a more rational manner. In this model Ellis explains it all for his clients, while Beck helps his clients figure this out on their own. Beck first started to notice these automatic distorted thought processes when practicing psychoanalysis, while his patients followed the rule of saying anything that comes to mind. Aaron realized that his patients had irrational fears, thoughts, and perceptions that were automatic. Beck began noticing his automatic thought processes that he knew his patients had but did not report. Most of the time the thoughts were biased against themselves and very erroneous.
