The term 'Introverted' occupies a foundational position in the depth-psychology corpus, anchored by Jung's 1921 formulation in Psychological Types, where introversion designates an attitude in which the determining agency of psychic life resides in the subject rather than the object. Across the library, commentators diverge sharply on what this primacy of the subject entails in practice. Jung himself articulates eight function-attitudes by combining introversion with each of the four functions — thinking, feeling, sensation, intuition — each yielding a distinct phenomenology with characteristic strengths, pathologies, and unconscious compensations. Thomson elaborates the lived consequences: the Introvert's initial negative response to external invitations, the reliance on an Extraverted persona as protective screen, and the inner world experienced as a 'secret place' of creative authority. Von Franz and Hillman press the clinical dimension, showing how inferior extraverted function-attitudes erupt under stress in introverted types with volcanic force. Quenk systematically maps these eruptions across all sixteen MBTI profiles, demonstrating that being forced to extravert while in the grip of the inferior function is as disorienting for Introverts as enforced introversion is for Extraverts. Beebe extends the model architecturally, linking introverted function-attitudes to specific archetypal roles within his eight-function schema. The central tension throughout is whether introversion designates a stable constitutional attitude, a contextual energic orientation, or a functional style deployed differently across conscious and unconscious strata.
I have called these two fundamentally different attitudes extraversion and introversion. Extraversion is characterized by interest in the external object, responsiveness, and a ready acceptance of external happenings
Jung establishes the foundational polarity of extraversion and introversion as two irreducible attitude-types differentiated by whether psychic energy flows primarily toward or away from the object.

Jung's structural table of contents in Psychological Types reveals how introversion is systematically elaborated through each of the four functions and their rational and irrational subtypes.

introverted feeling process... is conditioned subjectively and is only secondarily concerned with the object... It strives after inner intensity, for which the objects serve at most as a stimulus. The depth of this feeling can only be guessed
Jung characterizes introverted feeling as a fundamentally inward process that subordinates the object to the pursuit of an inner image, producing an intensity that remains largely invisible to outside observers.
, Psychological Types, 1921thesis
Being introverted, and having in consequence little capacity or desire for expression, they offer but a frail handle in this respect. As their main activity is directed inwards, nothing is outwardly visible but reserve, secretiveness, lack of sympathy
Jung summarizes the introverted irrational types as constitutionally opaque to external observation, their characteristic activity wholly oriented inward and their outward manifestations largely products of the inferior function.
, Psychological Types, 1921thesis
introverted thinking shows a dangerous tendency to force the facts into the shape of its image, or to ignore them altogether in order to give fantasy free play... It will have a mythological streak which one is apt to interpret as 'originality'
Jung identifies the characteristic pathology of introverted thinking as the subordination of empirical facts to archetypal inner images, lending it both creative power and a tendency toward self-enclosed fantasy.

From an Introverted perspective, outer reality can't be taken for granted. It's no more than an influx of perceptual data—meaningless, unless we give it the capacity to signify: with our thoughts, impressions, values, ideas, and interests.
Thomson argues that the Introverted attitude is defined by the necessity of conferring meaning on raw outer data through inner frameworks, making the inner world not a retreat but a constitutive requirement for any coherent engagement with reality.

an Introvert may seem indifferent or even hostile to a situation until he or she feels ready to take part... Introverts are highly aware of territorial imperatives, and they'll generally wait for cues that demarcate conversational space
Thomson demonstrates how the Introvert's characteristic initial hesitation and conversational restraint are strategic adjustments to protect inner coherence, not social indifference or hostility.

Introverts use a kind of Extraverted persona, which both accomplishes the tasks at hand and protects the inner self from unnecessary or unwanted engagement.
Thomson identifies the Introvert's deployment of an Extraverted persona as a protective mechanism that, when over-relied upon, can permanently impede genuine extraverted development.

When an introverted function is used to orient to something external, it is in the end the comparison to the archetype, not the stimulating object or situation itself, that finally commands the attention of the function.
Beebe's chapter in Papadopoulos clarifies that introverted functions orient to outer events by matching them against internal archetypal templates, so that the inner resonance rather than the external stimulus ultimately determines response.

Introverted sensation, as a process, is thus 'guided by the intensity of the subjective sensation excited by the objective stimulus'... When someone has been using the introverted sensation function primarily, seen from the outside, it looks as though the effect of the object did not penetrate into the subject at all.
Beebe illustrates introverted sensation as a process in which subjective inner resonance intercepts external stimuli so completely that the person appears unaffected while in fact being intensely internally engaged.

Beebe traces the historical architecture of Jung's system, showing how the introversion/extraversion polarity generates eight distinct function-attitudes that serve as the basis for the full typological model.

For the Introvert forced to extravert while in the grip of the inferior function, the discomfort and sense of losing one's bearings can be equally disruptive. The Introvert is less able to keep things inside
Quenk establishes that enforced extraversion is as disorienting for Introverts under stress as enforced introversion is for Extraverts, creating a symmetrical dynamic of inferior-function disruption across both attitude types.

They are mostly silent, inaccessible, hard to understand; often they hide behind a childish or banal mask... Their outward demeanour is harmonious, inconspicuous, giving an impression of pleasing repose... with no desire to affect others, to impress, influence, or change them
Sharp, citing Jung directly, portrays the introverted feeling type's characteristic social presentation as a deliberate or habitual concealment of an intense inner evaluative life behind an outwardly unassuming exterior.

The feeling of the introverted thinking type is extroverted... the feeling of the introverted thinking type is tied to external objects... it resembles the glue-like flow of feeling in an epileptoid person
Von Franz describes how the inferior extraverted feeling of the introverted thinking type, paradoxically object-bound and adhesive, contrasts sharply with that type's habitual detachment from outer relationship.

Important Features of Dominant Introverted Sensing Introverted Sensing types are careful and orderly in their attention to facts and details. They are thorough and conscientious in fulfilling their responsibilities.
Quenk delineates the characteristic strengths of dominant Introverted Sensing — conscientiousness, attention to detail, and fidelity to established fact — while contextualizing these within the dynamic of inferior-function vulnerability.

Others can experience both Introverted Sensing types as controlling and rigid, when in fact such characteristics are merely by-products of the natural style of these types.
Quenk distinguishes between the misperception of Introverted Sensing types as rigidly controlling and the actual typological explanation of such behavior as a natural extension of their dominant function's inherent style.

it is ordinarily that way for the introvert, the crowd heaping itself up into a monster before him... The fear the introvert feels rests on the unconscious assumption that the object is too much animated
Jung explains the introvert's characteristic social anxiety as rooted in an unconscious projection of excessive animation onto the object — a remnant of archaic magical thinking — contrasting it with the extravert's comfortable relation to the outer world.

One such consciousness, introverted sensation, is represented in The Red Book by the desperate horde of Anabaptists, ghosts from the sixteenth century, who invade Jung's space like an attack of indigestion
Beebe reads Jung's Red Book imagery as symbolic evidence that introverted sensation, when unconscious, manifests as intrusive, archaic, and bodily-insistent in a manner that bypasses rational control.

In projecting their inferior Extraverted Feeling onto others, Introverted Thinking types can readily see others' easy expression of emotion as hysterical and out of control.
Quenk shows how Introverted Thinking types, under stress, project their feared inferior extraverted feeling outward, misreading others' emotional expression as pathological rather than recognizing it as their own suppressed inferior function.

find an extraordinary concentration on inner processes... distinct tendency to solitude and fear of other people, often compensated by a special love of animals or plants. To make up for this, the inner processes are particularly active
Jung characterizes introverted personalities by their intensive inner processual activity, compensated outwardly by withdrawal from human society and a preference for the company of non-human nature.

Apparently seizing on Jung's assertion that the secondary function is 'not antagonistic to' the primary one, Jo Wheelwright concluded that the first two functions would have the same attitude with respect to extraversion and introversion.
Papadopoulos documents the interpretive divergence between Wheelwright and Myers on whether the auxiliary function shares or differs from the superior function's introversion/extraversion attitude, a debate central to the logic of type differentiation.

they tend to divide life experience into three basic sorts... situations that are out of control but must be endured. It is the latter category to which such types generally apply their Introverted skills, because they have no other options.
Thomson observes that certain extraverted types confine their introverted capacities to circumstances felt as uncontrollable, revealing how introversion can be defensively segregated rather than actively cultivated.

only introverted thinking would dig deep enough to find that development can not only get arrested, but that it can sometimes also take advantage of this arrest... to regress back to an earlier phase
Beebe argues that Freud's discovery of libidinal regression required the depth and complexity characteristic of introverted thinking, distinguishing it from the more linear explanatory style of extraverted thinking.

the inferior feeling of the introverted thinking type... resembles the glue-like flow of feeling in an epileptoid person; it has that kind of sticky, dog-like attachment which, especially to the beloved, is not amusing.
Sharp, citing von Franz, illustrates how the introverted thinking type's inferior extraverted feeling appears as undifferentiated, adhesive emotional attachment radically at odds with the type's usual detachment.
