Introduction
It is a widely held belief that Isabel Briggs Myers’ type theory is very similar to C.G. Jung’s, and that he endorsed her development of the MBTI® instrument. However, Jung had serious concerns about the popular presentation of his theory (Myers 2012a) and the letter apparently supporting Isabel Briggs Myers was not written by him and did not reflect his opinion (Myers 2012b). Jung expressed his attitude elsewhere by saying “God preserve me from my friends” (Jung 1957, p. 304) and felt the main point of his theory was being missed:
Typology [is] only one side of my book… Most readers have not noticed [the gravamen] of the book because they are first of all led into the temptation of classifying everything typologically, which in itself is a pretty sterile undertaking. (Jung 1935)
