Disclaimer: There is no popular opinions edition. I do not claim to be an expert, thus some information may not be correct. This book will be focused exclusively on MBTI, Jung's theory of personality and enneagram (but briefly and not always). By choosing to read this book, I will have assumed that you have an understanding of MBTI beyond the 4 letter code and have a decent understanding of Jung's theory of personality (the 8 types); you agree that any unwanted emotions that may arise are not my responsibility, but are a direct result of cognitive dissonance and unconscious, shoved feelings; you agree to risking almost the entire knowledge structure of what you know crumbling down onto the floor and you agree that my opinions are not set in stone, but debatable.
