In ‘The Question of Psychological Types‘, Jung and Hans Schmid-Guisan crafted early version of Jung’s later typology. In this manner, one may say that Jung and Schmid-Guisan both were the authors of this early typology, which we will call the Jung-Schmid-Guisan Typology (JSGT) for short. In this early version, extroversion is always identified with Feeling and introversion is always identified with Thinking.
It is important to keep in mind that with regards to his own later typology, Jung made many alterations to it afterwards. One should therefore take care not to confuse apples with oranges, and this is also the reason that none of these claims are included on the main site. However, as a matter of historical importance to the purpose of our site, we offer it to the reader below. (All page numbers are from ‘The Question of Psychological Types.’)

As for the question of Hans Schmid-Guisan’s type in terms of the standard Jungian typology, John Beebe identifies Schmid-Guisan as an ENFP in the book’s introduction (p. 27), while, in a recent work, V.W. Odajnyk types Schmid-Guisan as an E-F type.
