When it comes to MBTI/Functions and this shadow concept, I guess I had no opinion until I read Beside Ourselves. It made more impact on me than any book I'd read on MBTI. At first, I saw how what was being described resonated with me personally. Then I sought evidence as to how other types behaved when "in the grip of the inferior". I found numerous examples supporting the theory/concepts.
Let's look at one example - what an eruption of the inferior looks like for an Introverted Intuitive type (e.g. INTJ and INFJ). From "Beside Ourselves":
Typical provocations or triggers
- "dealing with details, especially in an unfamiliar environment. " It is described, how at times, we feel "overwhelmed with details". Another trigger is "too much extraverting."
What happens to the Introverted Intuitive?
A few examples:
"Obsessive Focus on External Data" - "experienced as a state of intensity and drivenness", "obsessing about facts and details", "i stew about what is going on...am mentally fatigued and find myself putting things in order and trying to control everything around me", "i nitpick about things in the environment. i bombard people verbally and obsess out loud", "i get hung up on some false fact and distort it"
"Overindulgence in Sensual Pleasures" - "takes the form of sensual excess rather than sensual pleasure"
"Aversarial attitude towards the outer world" - "I feel anxious, exposed and childish", "I become dogmatic and blast people with facts", "I am angry, unreasonable, totally irrational, close minded, and impatient"
