The evaluation is to determine the subject’s external physical traits broken down by Body Adiposity (Endomorphy), Muscularity (Mesomorphy) and Linearity (Ectomorphy). Scores are typically done on a 0.1, (low characteristic of trait) to 10.0 (high characteristic of trait) scoring system for each component, and compared with similar reference populations or known celebrities.
Endomorphy is determined from fat skinfold thicknesses based on selected sites,Â
Mesomorphy the flexed bicep and calf girths are measured with a Gulick tape.  The subcutaneous fat contribution of the bicep and calf girths are estimated and removed.  A skeletal anthropometer estimate bones diameters of the femur (thigh) and humerus (upper arm), and the bones contribution to the bicep and calf girth measurement is eliminated.  The resulting muscle mass remaining is scored.Â
Ectomorphy is ratio of height and weight, similar to a BMI called the Ponderal Index.  This measurement is then allometrically scaled to account for individual differences in body dimension.Â
The Meyers/Briggs Personality Assessment
This test has proven popular for the evaluation of personality type on a four-component scale.  For each pair of traits examples are provided, and the individual selects the trait of the pair that best typifies their own personality.  At the conclusion of answering the questions, four letters are given to describe your personality type, (example: ESTP or IMFP) Â
(E)Extrovert or (I)Introvert
(S)Sensing or (N)Intuitive
(T)Thinking or (F)Feeling
(J)Judging or (P)Perceiving
Somatogram is then plotted to see how the individual’s body type and personality type mesh.  For example, if a subject is high is mesomorphy, they may possess more testosterone than the average person making them more aggressive.  If they are more muscular they could be an athlete and they may be more of a leader than follower, they be more confident, and hence would be an extrovert.Â
Although not an exact science, but could provide interesting insight to the relationship between your own mind and body connection.
