W. Sheldon’s theory vs. Myers-Briggs’s type indicator
Every person is a world unto himself. No wonder it is an enigma which they can even last all their whole life in order to solve it. Everyone is undoubtedly unique, hence that there are certain aspects, in the way of thinking or acting of everybody, which gives the chance to classify them. The psychology is the responsible to link each trait from people in different groups. As we know, in the first half of the twentieth century there were a lot of famous and great psychologists, among them I would highlight: William Sheldon and the family Myers-Brigg. They both made different theories about some ways to relate the people’s physical status and their way to act with their thoughts and feelings. My purpose is to contrast both theories in order to clarify their points of view, mainly whether it is based on theory or scientific experimentation; range and the method of application; the number of possible types and the credibility of the theory.
First of all, William Sheldon, before finishing of developing his theory of body type and temperament, he made clearly some scientific experimentation. For instance, he looked at 4.000 photographs of college-age men in front, back and side views; moreover, he also did in-depth interviews of several hundred people. From then on he finally achieved his goal. Whereas the Myers-Briggs’s type indicator was based on Jung’s typology (a Swiss psychologist), so it is based on theory, there is no a previous experimentation as Sheldon did.
Both systems have a very different method of application. At first, the Sheldon’s theory was only focused in the human physique, based on three components of physical form (endomorphy, mesomorphy, ectomorphy) and drawn in a triangular diagram, later on W. Sheldon achieved to link these three components to their own personalities (endotonic, mesotonic, ectotonic); in contrast to the Myers-Briggs’s type indicator, which had always been fully focused...
