The term 'Neuroticism System' occupies a contested but productive space within the depth-psychology corpus, appearing most visibly at the intersection of trait personality research and clinical psychodynamics. In empirical strands of the literature—principally Yalom's group-therapy investigations and the aesthetic-personality studies of Johnson and Williams—neuroticism functions as a measurable five-factor construct (NEO-FFI/NEO-PI-R) that reliably predicts poorer therapeutic outcomes and operates independently of openness, extraversion, conscientiousness, and agreeableness. Here the 'system' dimension is largely implicit: neuroticism indexes a dispositional vulnerability whose systemic effects ramify across treatment modalities. In Horney's structural account, the concept is transformed into something architecturally richer: the pride system, the idealized self, and neurotic claims collectively constitute what functions as a self-reinforcing psychic system of defence against anxiety and self-alienation. Craig and Schore approach adjacent territory neurobiologically, locating neuroticism-adjacent traits in frontolimbic bias, autonomic set-points, and affect-regulatory failures of early development. The key tension in the corpus is between neuroticism as a stable dimensional trait amenable to psychometric measurement and neuroticism as a dynamic, structurally embedded system whose roots lie in developmental relational failures. Both framings agree that the system resists straightforward therapeutic resolution; they disagree on whether its locus is constitutional, relational, or intrapsychic.
One personality factor, neuroticism, predicted poorer outcome in both types of group. Three factors predicted good outcomes with both treatments: extraversion, conscientiousness, and openness.
Yalom presents empirical evidence that neuroticism, measured via the NEO-FFI, functions as a systematic predictor of therapeutic failure across both interpretive and supportive group modalities.

Although human relations are of signal importance, they do not have the power to uproot a firmly planted pride system in a person who keeps his real self out of communication.
Horney argues that the neurotic system—anchored in the pride system—is structurally resistant to change through relational means alone, establishing the system's intrapsychic autonomy.

His uncertainty is closely interwoven with his fears because, even though others do in fact represent a greater threat to him, his fears would not skyrocket as easily as they do if it were not that his picture of others is distorted anyway.
Horney maps the self-reinforcing dynamics of the neurotic system, showing how distorted object relations and the pride system mutually amplify anxiety and interpersonal fear.

we examined associations with the other four NEO domains (Neuroticism, Extraversion, Agreeableness, Conscientiousness) to rule out the possibility that shared variance with other personality variables was driving the association.
Johnson treats neuroticism as a confounding system-level variable requiring statistical control when assessing the independent predictive power of openness and aesthetic engagement.

a follow-up study by Wittmann and colleagues reported that individuals who performed poorly on the time-reproduction task had higher impulsivity scores... a paper reported that individual differences in time-reproduction accuracy... correlated with gray matter volume.
Craig situates neuroticism among a cluster of personality traits—including extroversion—that correlate with sympathovagal balance and interoceptive self-monitoring, grounding the neuroticism system in neurobiological substrate.

He is like a person who believes he has a warranted claim to an inheritance; instead of making constructive efforts in living, he puts all his energies into a more effective assertion of his claims.
Horney illustrates the operational logic of the neurotic system through the mechanism of neurotic claims, showing how the system forecloses genuine self-development in favour of perpetuating its own defensive structure.

the stigma attached to the neurotic person seems to us to be unfounded and justified only if we think of neurotic in terms of social efficiency... a society could be called neurotic in the sense that its members are crippled in the growth of their personality.
Fromm extends the neuroticism concept from individual pathology to a systemic social dimension, arguing that entire societies may instantiate neurotic mechanisms when they obstruct personality growth.

frontolimbic biases reflect an autonomic set point which expresses a predominance of one of the forebrain-midbrain limbic circuits... this characterological feature of an individual personality is most observable under particular conditions that are appraised to be personally stressful.
Schore provides a neurobiological underpinning for trait-level neuroticism by linking characterological predispositions to frontolimbic circuit dominance and autonomic set points established in early development.

Individuals can become neurotic when they are unable to find the right position between the two... there are two types of neurosis either side of normality.
Myers, drawing on Jung, frames neurosis as a systemic failure of adaptive equilibrium between individual and collective poles, producing two structurally distinct neurotic configurations.

The taboos on feelings of tenderness, sympathy, and confidence can be just as great in some neurotics as the taboos on hostility and vindictiveness are in others.
Horney demonstrates the structural symmetry within the neurotic system, whereby opposite emotional prohibitions produce equivalent functional impoverishment across neurotic types.

The PACE measure was not significantly related to NEO-FFI Neuroticism, Extraversion, Agreeableness, or Conscientiousness... but was significantly correlated with the NEO-PI-R Openness factor.
Williams establishes the discriminant validity of aesthetic chill proneness relative to the neuroticism system, confirming that aesthetic responsiveness is orthogonal to neurotic disposition.

He can deal with others only when at a safe emotional distance; thrown into closer contact, he is inhibited in addition to being handicapped by his recoil from fighting.
Horney sketches the relational consequences of the resigned neurotic solution, illustrating how the neuroticism system configures interpersonal distance as a protective mechanism.

Both of these narcissistic types suffer from a developmental arrest of narcissism regulation... due to the failure to evolve a practicing affect regulatory system which can neutralize grandiosity.
Schore links neuroticism-adjacent pathology to developmental failures of the affect-regulatory system, connecting the neuroticism system to the broader ontogeny of personality disorder.
