The Genetics of Psychological Type

This analysis involves a quick review of Mendel's work recognizing the 75% - 25% split between dominate and recessive traits or characteristics. The author then reviews basic personality theory with an emphasis on the works of Jung expanded by Briggs and Myers and further developed by the MBTI successor organization. A review is conducted to arrive at a more scientific review of each of the identified elements. Over a period of years, studies were made which included statistics for each of the major characteristics in relation to each other. For the E/I pair, E is dominant and I recessive, For S, everyone senses but only 25% have the N characteristic, And for the T/F pair a sex related difference was found and for males T is dominant and for females F is dominant resulting in what looks like a 50% - 50% in T and F when the total population is viewed. And, for the last pair, J/P, There is a even split between the two. Based upon percentages seen, Expected Percentages for each of the 16 types are calculated. Gene studies are needed to confirm the results.
