Introversion and extraversion (Jung's original sense)
For Jung, the extravert orients to the object: outer facts, people and events set the terms, and the person adapts to them. The introvert orients to the subject: the inner response to the object is what counts, and outer reality is filtered through it.
What drives it
It explains why two people in the same meeting can be looking at different things: one at what is happening, the other at what it means to them. That reading of orientation is more useful for identification than the popular sociability version, because a talkative person can be introverted in Jung's sense and a quiet one extraverted.
How it shows
Work
The Jungian extravert asks 'What does the market want? What did the client say?' and adjusts fast; the Jungian introvert asks 'Does this fit how I see it?' and may hold a position against the room. A gregarious founder who ignores all feedback in favour of private conviction is introverted in Jung's sense.
Relationships
The extraverted partner reads the relationship from what is said and done; the introverted one from an inner sense of it, and may be hurt by things the other never noticed happening.
Self
Ask where your sense of what is real comes from when the two clash: the facts and other people's reactions, or your own inner reading. Which one do you trust when they disagree?
What tells it apart
Extraversion: Big Five extraversion is about sociability, assertiveness, energy and reward-seeking, measured by how much you seek out people and stimulation; Jung's attitude is about whether outer facts or inner response govern judgement, which you see in how someone handles disagreement, not in how much they talk.
Schizoid personality: Jung's introvert is engaged with the world through a subjective lens and can be warm; schizoid character withdraws from relating itself and shows flat or guarded contact.
A test
Watch what happens when outer evidence contradicts the person's inner view: a quick update points to Jung's extraversion, a reinterpretation of the evidence to fit the inner view points to his introversion.
Questions to carry
- When outer evidence contradicted the inner view, what happened next, an update or a new reading of the evidence?
- In the last meeting I sat through, what held my attention, the events or what they meant to me?
Go deeper
- Read: Man and His Symbols, Carl Jung and colleagues, 1964. The one book Jung planned for general readers, finished by his colleagues after his death.
- Watch: When Someone Lives Too Much in Your Mind, Jung at Night, YouTube. A narrated take on why one person can take up so much room in our thoughts, in Jung’s terms. We haven’t checked its quotes against Jung’s own writing.
How strong the research is
clinical. Jung's version, about the direction of psychic energy, was never operationalised; the modern trait of extraversion that grew from it (via Eysenck and the Big Five) is one of the best-supported constructs in psychology but means something narrower and different.
