The source of all data interpolation/extrapolation in MAPP, these twenty-three core “traits”, identify a unique quantification and qualification for each individual. Because of the interplay and inter-dependency between these traits and their values, the possible combinations are almost beyond human comprehension. It is greater than the total number of people who ever lived on this earth. The actual expression would be seventeen to the one hundredth power interacting with seventeen to the eleventh power. It is suggested that serious study be applied to this list in order to get some idea of what happens when your individual traits simultaneously attempt to influence thoughts and actions. Sometimes traits are complementary and, therefore, strengthen, reinforce, and encourage other traits. Sometimes traits are totally contrary and antagonistic to each other. This may result in one trait trying to prevent expression and satisfaction of another. If only one can be expressed, the other may cause stress.
