History has recorded many attempts to explain why people are different. One of the first systems developed was Astrology, which looked outside of man. Hippocrates (470-360 B.C.), however, looked inside of man to explain the differences in people. He believed that behavior was determined by the presence of an excessive amount of one of four fluids or humors; yellow bile (High D); red bile (High I); white bile (High S); black bile (High C). The insightful observations of Hippocrates laid the foundation for the temperament model of behavior.

Since Hippocrates identified the four temperaments, numerous men have refined, added to, and advanced the concept that people are born with natural tendencies. One of these pioneers, William M. Marston, scientifically identified the same four groups of tendencies in 1928 and coined the terms, Dominant, Influence, Steady and Compliant. Marston's terms and descriptions correlate to the original four humors identified by Hippocrates. The DISC II Temperament Assessment is based on Marston's work as well as empirical evidence from years of research, thousands of interviews and testing since 1974.

The natural tendencies that a person possesses represent various "needs" that will endure throughout a person's life-span. The temperament model of behavior suggests that people perform best when the needs of their natural tendencies are consistently met.

This report is taken from the online DISC II Temperament Assessment and is a reflection of the dynamics coming from the blend of the primary and secondary temperaments. It describes the respondent's temperament blend or pattern. This represents a general description of behavioral tendencies.

Of the three graphs shown, Graph III will be used as the best description of the individual's behavioral tendencies.
