Seligman developed treatments after observing other psychologists during World War II. Instead of focusing on people who are disturbed or traumatized, the doctor concentrated solely on the ability to be happy despite the conditions. This led him to understand the workings of people being happy in spite of the adverse conditions that they are put in. Furthermore, he concluded through his study that if both community and people around the patient are happy, there is a rapid improvement in the patient also. This meant that when psychology could change a negative outlook to that of the positive one, society would benefit from the encouraging and favorable disposition of the individual.
