A separation exists between psychology and typology. Many psychologists and even many Jungians ignore Jung’s major work, Psychological Types, and the concepts underlying it. The field has been left mostly to lay practitioners, who use the MBTI® instrument for training, coaching, and other pragmatic applications. What reasons do you see for the divide?

Individuation (which, within the conceptual framework of the type model, is essentially synonymous with ‘type development’) is usually unpleasant, and a positive outcome is far from guaranteed. So why do so many regard it as the psychic purpose of human existence? Why do we do it? What drives us to it? What has been your experience?

I see very clear portrayals of the function-attitudes in my canine friends. They often manifest in such simple and “pure” form that I feel I’ve been given a glimpse of how our human typologies may have evolved, and at what the function-attitudes “look like” without the complex dynamics and conscious obfuscation of human personalities.

Which do you trust more to give you reliable information about type: observation or introspection? And what is your type preference? Of course, all type users rely upon both the observation of others and internal self-reflection to expand and confirm their understanding of personality type. But it seems as though we differ in which we prefer.

Within the function-attitude preference hierarchy for each type, there are three natural groupings which seem to reflect a “Me, Spirit, and Other” delineation and describe our areas of “strength, vulnerability and creativity, and defense,” respectively. Is it more than a coincidence that this configuration has parallels in most traditional world views, as “Earth, Heaven, and Underworld?”

I allowed myself to take a little vacation from my single-mindedness and felt a shift in attitude and awareness almost immediately. My linear, tunnel-vision mindset relaxed, and I began to notice and embrace information, insights, and opportunities that came along unexpectedly and felt important despite having no logical connection with the task at hand.

Do you use your dominant function-attitude confidently? Heroically? Do you know when to trust it, even if no one else does? Many people grow up in families and/or cultures that don’t support their preferred ways of seeing the world and operating in it. So underdevelopment of our naturally preferred functions is probably a common type-development issue …

How might type development affect judgment lapses that result in plagiarism? Can we use our understanding of type to address this problem? Two high-profile journalists were recently removed from their posts for reasons of plagiarism—New Yorker staff writer Jonah Lehrer, and Time editor-at-large and CNN host Fareed Zakaria. On July 30, Lehrer …

She could not compete with me in the extraverted thinking mode that I (and our culture) insisted upon, so my well-meant out-reaching felt like attacks to her, and my peace offering of objective discussion was like a Viking’s looming battle-axe. Rather than take part in a Te confrontation that she couldn’t win, she had changed the rules, initiating an introverted feeling battle of attrition.

In the type table in the accompanying article on the type-diverse classroom, almost 60% of the ‘at risk’ and drop-out students are reported to have dominant extraverted perception, while almost half of the teachers are dominant introverted perceivers. Is extraverted perception misdiagnosed as a learning disability? Or, is that preference actually problematic …

Is it INTJ or INTP? Sometimes the MBTI code’s judging/perceiving (J/P) dichotomy is extremely difficult to nail down—showing a low preference clarity on the report and proving elusive to verify. INTJ vs. INTP seems especially problematic. Why is J/P so difficult? Do you have any tips for verification?

Our often-used shorthand illustration with a line drawn between the four allegedly conscious function-attitudes and the four “unconscious” ones is misleading because consciousness is not a sufficiently reliable characteristic for distinguishing these two sides of the psyche’s typology. It’s related to what distinguishes them, but only as a secondary and fairly unpredictable characteristic.

The modern emphasis on self-awareness seems to have taken our psychological development about as far as it can for now; further progress requires the pendulum to swing towards attending to our interrelatedness, toward Self-awareness. The two most active and influential sociopolitical worldviews of our time, conservatism and progressivism, are both demonstrably collective in orientation.

Academic personality research likes to consider trait psychology to be the scientific revolution that overtook and replaced Jung’s type psychology. However, it may be more accurate to view type and trait models as complementary because the conceptual divide has been shifting, and many trends in academic personality research now reflect the fundamental principles of Jung’s type system.

Some of the most difficult people to deal with are extraordinarily competent but refuse to share power or flex to consider other perspectives. Thus, they become obstructionists in contemporary society; and numerous studies of modern corporations have found “a disproportional number of narcissistic individuals [in] executive leadership positions.”
