This episode, which is Part 8 of this 10 part series on the enneagram, focuses on the issue of typing and mistyping — why it happens, how to approach typing, as well as a few of the common enneatype confusions. Two books in particular informed the content of this episode (and go into far more detail than it was possible to cover in just over 20 minutes): Sandra Maitri's "The Spiritual Dimension of the Enneagram" and Beatrice Chestnut's "The Complex Enneagram."
