Personologists look at a physical structure and determine how it indicates a behavior pattern. Millions of people have an intense desire to understand the links between genes, appearance, and behavior. Personology explains how our genes express themselves in our structure and personality. Everyone knows that our ancestors' genes contain the data that makes us more like them and different from others. After all, each of us probably has a strong resemblance in mannerism and appearance to someone in our immediate family.
Structure indicates function.
Everyone has the same traits except to different degrees. Each trait has its place, large and small, in the total picture of an individual. Each trait can cancel or intensify the expression of other traits. Personology, therefore, shows us a truer picture of the how and why of our differences. People get rational and reliable explanations for their feelings, speech, and actions.
