Abstract

Narcissism, which psychoanalytic theory introduced and under which the Medical Subject Headings file it, names a personality style organised around grandiosity, entitlement, and a fragile need for admiration. Sigmund Freud framed it as libido invested in the self; Heinz Kohut and Otto Kernberg built opposed clinical theories of it as a developmental deficit or a defensive structure. Contemporary personality science has largely abandoned the single-type picture for a two-dimensional one, distinguishing grandiose narcissism, marked by boldness and self-promotion, from vulnerable narcissism, marked by hypersensitivity and distress, with entitlement as their shared core. Process models recast the trait as a self-regulatory system: the narcissist pursues esteem through admiration-seeking and defends it through rivalry. The result is a construct measured, dimensionalised, and dynamically modelled rather than diagnosed by type.

Keywords: narcissism, grandiosity, vulnerable narcissism, self-regulation, entitlement

Few personality terms carry as much everyday weight, or as much theoretical disagreement, as narcissism. It began as a clinical idea: Freud borrowed the myth of Narcissus to name a turning of sexual energy back onto the self, and made it a developmental stage and a form of pathology (Freud, 1914/1957). A century later it is one of the most actively studied constructs in personality psychology, and the object of a sustained empirical effort to decide what it is, how many dimensions it has, and how to measure it (Miller et al., 2017). The Medical Subject Headings file the concept beneath psychoanalytic theory, the tradition in which it was coined, but the modern science of narcissism is built on psychometrics and social-personality process models rather than on the libido economics of its origin (Pincus et al., 2009; Morf & Rhodewalt, 2001).

Key Takeaways
  • Narcissism names a personality style built around grandiosity, entitlement, and a need for admiration that masks an underlying fragility of self-esteem.
  • Freud introduced it as libido invested in the self; Kohut and Kernberg then built opposed clinical theories of it as a developmental deficit versus a defensive structure.
  • Modern personality science distinguishes two dimensions: grandiose narcissism (bold, self-promoting, approach-oriented) and vulnerable narcissism (hypersensitive, defensive, distress-prone).
  • Entitlement and antagonism are the shared core that the grandiose and vulnerable presentations have in common, which is why both count as narcissism.
  • Process models treat narcissism as a self-regulatory system: esteem is pursued through admiration-seeking and protected through rivalry, which explains why narcissists are liked at first and disliked over time.

What Narcissism Is

Narcissism is, in its modern sense, a personality style in which self-esteem is maintained through grandiosity, a sense of entitlement, and the pursuit of admiration from others, resting on a self-concept that is both inflated and precarious (Pincus et al., 2009). The word retains the shape of the myth from which Freud took it, the youth who fell in love with his own reflection, but the construct has long since detached from that origin and become a quantitative, multi-dimensional object of study.

Two features organise everything that follows. First, narcissism is not one thing: the term covers a grandiose presentation of boldness, dominance, and self-enhancement and a vulnerable presentation of hypersensitivity, shame, and defensive withdrawal, and the relation between the two is the central problem of the field (Cain et al., 2008; Miller et al., 2011). Second, the construct spans a range of severity, from a normal personality trait distributed in the general population through to narcissistic personality disorder, so that the same underlying dimensions describe both an ordinary difference between people and a clinical condition (Krizan & Herlache, 2018). The sections below trace the concept from its psychoanalytic origin, through the deficit-versus-defence debate, to the two-dimensional, measured, and process-based account that now dominates.

From Freud to the Clinic

Freud's 1914 paper On Narcissism made the term a technical concept (Freud, 1914/1957). He distinguished primary narcissism, the infant's original investment of libido in itself before it has learned to love others, from secondary narcissism, the later withdrawal of that libido from the world back onto the self. Narcissism in the pathological sense was this secondary withdrawal: a redirection of love away from external objects and onto the ego, which Freud used to explain states from hypochondria to the grandiosity of psychosis. The account was continuous with his economic model of a finite libido traded between self and world, and it placed narcissism at the centre of psychoanalytic theorising about the ego.

The clinical tradition inherited two difficulties from this origin. The first was definitional: Freud's narcissism was a stage and an energy distribution, not a personality type, and translating it into a describable character structure took another half-century. The second was that the construct, as Freud left it, conflated self-love with self-regard, grandiosity with withdrawal, and normality with pathology. The mid-century object-relations theorists took up the task of turning narcissism into a clinical syndrome with a describable structure, and in doing so produced the field's defining disagreement (Kernberg, 1970; Kohut, 1971).

Kohut Versus Kernberg: Deficit or Defence

The two great clinical theories of narcissism were published within a year of each other and disagreed almost completely. Heinz Kohut, founder of self psychology, treated narcissism as a normal developmental line that could be arrested (Kohut, 1971). On his account the child needs selfobjects, others who perform mirroring and idealising functions for a self that cannot yet perform them alone, and pathological narcissism is a developmental deficit: a self left fragile and hungry for the admiration it never adequately received. The therapeutic implication is empathic, a supplying of the missing selfobject functions.

Otto Kernberg, working from object-relations theory, read the same clinical picture as a defence rather than a deficit (Kernberg, 1970). For Kernberg the grandiose self of the narcissistic patient is a pathological structure, a fusion of the ideal self, the ideal object, and the real self, erected to defend against envy, rage, and a devalued internal world. The grandiosity is not an arrested-but-normal self but a construction over something darker, and the therapeutic stance is correspondingly confrontative, interpreting the aggression the grandiosity conceals. The deficit-versus-defence opposition, Kohut's fragile self needing supply against Kernberg's defensive structure concealing aggression, framed clinical thinking about narcissism for a generation, and its echo survives in the modern distinction between vulnerable and grandiose presentations.

Grandiose and Vulnerable Narcissism

The single most important development in the empirical study of narcissism is the recognition that it has (at least) two dimensions that behave very differently (Cain et al., 2008; Miller et al., 2011). Grandiose narcissism is the presentation that matches the folk stereotype: overt self-importance, dominance, boldness, exhibitionism, and a relative immunity to the opinions of others. Vulnerable narcissism is its covert counterpart: the same underlying entitlement and self-absorption, but expressed as hypersensitivity to slight, shame, anxiety, defensive withdrawal, and a self-esteem that swings with external feedback.

The two dimensions are only weakly correlated, and they relate oppositely to almost everything measured outside narcissism (Miller et al., 2011). Grandiose narcissism loads on extraversion and low agreeableness, is associated with high self-esteem and psychological boldness, and in its milder forms can look like confident leadership. Vulnerable narcissism loads on neuroticism and low agreeableness, is associated with distress, insecure attachment, and poor wellbeing, and is the presentation that most resembles a clinical disorder. The marker the two share, and the reason both count as narcissism rather than as unrelated traits, is antagonistic entitlement: an inflated sense of deservingness and a willingness to exploit, which structural analyses recover as the common core of the construct (Crowe et al., 2019; Weiss et al., 2019). Figure 1 shows why the two dimensions cannot be collapsed into one: if grandiosity and vulnerability were a single trait, people would fall along a diagonal, but measured together they scatter across the plane. The first model lets the reader place a person in the grandiose-by-vulnerable plane and read off the resulting profile.

Figure 1

Grandiose and vulnerable narcissism as two weakly correlated dimensions A scatter plot with grandiose narcissism on the horizontal axis and vulnerable narcissism on the vertical axis. A dashed diagonal line marks what a single-trait model would predict, with grandiosity and vulnerability rising together. The plotted people do not lie on that diagonal; they scatter widely across the plane, including high-grandiose low-vulnerable points at the lower right and low-grandiose high-vulnerable points at the upper left, showing that the two dimensions are only weakly correlated and cannot be reduced to one. vulnerable narcissism grandiose narcissism one-trait prediction a measured person People scatter off the diagonal: grandiosity and vulnerability are only weakly correlated.
If narcissism were a single trait, grandiosity and vulnerability would rise together along the dashed diagonal. Measured jointly, people scatter across the plane, which is the empirical basis for treating narcissism as (at least) two weakly correlated dimensions rather than one level.

The Narcissism Spectrum

If grandiose and vulnerable narcissism share a core, the natural question is how to represent the whole construct. The Narcissism Spectrum Model of Krizan and Herlache answers it by placing entitled self-importance at the centre and treating grandiosity and vulnerability as two directions of expression from that shared centre (Krizan & Herlache, 2018). Grandiosity is the approach-oriented expression, boldness, dominance, and reward-seeking; vulnerability is the avoidance-oriented expression, reactivity, insecurity, and threat-sensitivity; and entitlement is what every narcissist, grandiose or vulnerable, has in common.

The spectrum view resolves a long-standing puzzle. Clinically, grandiose and vulnerable patients can look like opposite kinds of person, yet the same individual can shift between them over time and context, the grandiose narcissist collapsing into vulnerability under failure, the vulnerable narcissist flashing grandiosity when safe. A model with a shared core and two expressions captures both the stable between-person differences, how much entitled self-importance a person carries, and the within-person movement between a bold and a fragile face of it (Krizan & Herlache, 2018). The second model renders the spectrum directly, letting the reader vary the core and the direction of expression and see the profile that results.

Measuring Narcissism

Narcissism became an empirical science when it became measurable. The Narcissistic Personality Inventory (NPI), introduced by Raskin and Hall and given its enduring factor structure by Raskin and Terry, was the instrument that moved the construct out of the clinic and into the personality laboratory (Raskin & Hall, 1979; Raskin & Terry, 1988). The NPI measures narcissism as a normally distributed trait in the general population, and the two decades of research it enabled established the correlates, the developmental course, and the social consequences of what is now recognised as grandiose narcissism specifically.

That last qualification is the NPI's limitation and the reason the field built successors. Because the NPI taps the bold, self-promoting, grandiose face of narcissism, it is nearly blind to the vulnerable dimension, and a literature that relied on it alone systematically under-represented half the construct (Cain et al., 2008). The Pathological Narcissism Inventory (PNI) of Pincus and colleagues was built to capture both grandiosity and vulnerability and the oscillation between them, and it reframed pathological narcissism as a dysregulation of self-esteem rather than a stable level of it (Pincus et al., 2009). Meta-analytic work on the trait has since mapped its structure in detail, including a robust but modest gender difference, with men scoring higher on grandiose narcissism, especially entitlement and exploitativeness (Grijalva et al., 2015).

Admiration and Rivalry: A Process Model

A different line of work asks not what narcissism is but what it does, treating it as a self-regulatory process. Morf and Rhodewalt's dynamic self-regulatory processing model framed narcissism as a chronic project of constructing and defending a grandiose self-image through social interaction, with the paradox that the very strategies that build esteem in the short run undermine the relationships that would sustain it (Morf & Rhodewalt, 2001). Back and colleagues sharpened this into the Narcissistic Admiration and Rivalry Concept (NARC), which splits grandiose narcissism into two distinct pathways to the single goal of a grandiose self (Back et al., 2013).

Admiration is the agentic, self-promotion pathway: striving for uniqueness, charmingness, and grandiose fantasies, which produce social potency and, at first meeting, genuine popularity. Rivalry is the antagonistic, self-defence pathway: striving for supremacy, devaluation of others, and aggressiveness, which produce social conflict and, over repeated interaction, rejection. The NARC explains one of the most reliable findings about narcissists: they are liked on first acquaintance, because admiration is what shows first, and progressively disliked as acquaintance lengthens, because rivalry accumulates (Back et al., 2013). This admiration-then-rivalry dynamic also underlies the robust link between narcissism, especially its antagonistic, rivalrous component, and aggression following ego threat (Kjærvik & Bushman, 2021). The third model sets admiration and rivalry independently and traces the popularity trajectory their balance produces; the worked example computes a case in full.

Worked Example

The NARC's central claim is that liking changes sign over time because admiration and rivalry act on different schedules, and the third model renders the consequence. Suppose liking for a narcissistic person after t interactions is written as a weighted sum of their admiration A and rivalry R, L(t) = wA(t)·A − wR(t)·R, where admiration's weight decays as novelty fades, wA(t) = e−0.25t, and rivalry's weight grows as conflict accumulates, wR(t) = 1 − e−0.25t. Take a person high on both, A = 8 and R = 7 on a 1–10 scale. These numbers are didactic, chosen to make the structure visible, not estimated parameters.

At first meeting, t = 1: wA = e−0.25 = 0.779 and wR = 0.221, so L(1) = 0.779(8) − 0.221(7) = 6.23 − 1.55 = +4.68, a strongly positive impression. After ten interactions, t = 10: wA = e−2.5 = 0.082 and wR = 0.918, so L(10) = 0.082(8) − 0.918(7) = 0.66 − 6.43 = −5.77, a strongly negative one. The same person, with unchanged admiration and rivalry, moves from markedly liked to markedly disliked purely because the two pathways are weighted differently as acquaintance lengthens.

A single-dimension model of narcissism cannot produce this reversal, because it has only one quantity whose sign cannot change: whatever liking it predicts at first meeting it must predict, attenuated, later. The NARC produces it because it carries two processes with opposite social consequences and different time courses, which is the worked form of the chapter's argument that narcissism is better described by separable dimensions than by a single trait level (Back et al., 2013).

Discussion

The trajectory of the narcissism construct is the reverse of the libido concept from which it sprang: where libido was a strong mechanism attached to a real question, narcissism was a real phenomenon in search of a workable structure, and the structure arrived through measurement. Freud's self-invested libido and the Kohut-Kernberg debate identified the clinical reality, a self that is at once inflated and fragile, but could not say how many dimensions it had or how to count them. The answer, reached empirically, is that narcissism is minimally two-dimensional, grandiose and vulnerable, over a shared core of entitled antagonism, and that the clinical, trait, and process literatures converge on that picture once the measurement is right (Miller et al., 2017; Crowe et al., 2019).

Table 1. Grandiose and vulnerable narcissism compared.
Feature Grandiose narcissism Vulnerable narcissism
Overt presentation Bold, dominant, exhibitionistic Hypersensitive, anxious, withdrawn
Big Five loading High extraversion, low agreeableness High neuroticism, low agreeableness
Self-esteem High and relatively stable Low and feedback-dependent
Shared core Entitlement and antagonism
Chief instrument NPI PNI (both dimensions)

What remains contested is the architecture above that core. The trifurcated model argues that narcissism resolves into three building blocks, agentic extraversion, self-centred antagonism, and narcissistic neuroticism, drawn from general personality structure, so that grandiose and vulnerable narcissism are different weightings of the same elementary traits rather than two irreducible types (Weiss et al., 2019). Whether narcissism is best treated as a thing in its own right or as a configuration of ordinary personality dimensions is the live disagreement, and it is a disagreement the field can now have precisely because the measurement is good enough to adjudicate it (Miller et al., 2017).

Current Directions

The most active empirical front is the within-person dynamics of narcissism: the movement between grandiose and vulnerable states in the same individual over hours and days, studied with experience-sampling and modelled as a state process rather than a fixed trait (Edershile & Wright, 2022). This work asks when a grandiose narcissist tips into vulnerability and what triggers the swing, treating the two dimensions not as two kinds of person but as two states a narcissistic self-regulation system moves between, and it is the direct descendant of Morf and Rhodewalt's process model armed with the tools to observe the process in real time.

A second front is structural: large-sample factor-analytic and item-response work aimed at settling whether narcissism's core is best modelled as entitled self-importance, as antagonism, or as the trifurcated set of elementary traits, and how the many instruments map onto one another (Crowe et al., 2019; Weiss et al., 2019). A third is consequential: meta-analytic consolidation of what narcissism predicts, from aggression after ego threat to leadership emergence and relationship trajectories, which turns the construct from a description into a set of testable forecasts (Kjærvik & Bushman, 2021; Grijalva et al., 2015). What unites the three is the strategy that has served the field best since the NPI: keep the clinical phenomenon the psychoanalysts identified, and answer it with measurement, dimensional structure, and observed dynamics rather than with a single postulated type.

Frequently Asked Questions

What is narcissism in psychology?

Narcissism is a personality style organised around grandiosity, entitlement, and a need for admiration that rests on a self-esteem that is both inflated and fragile. In modern personality science it is a measurable, normally distributed trait with grandiose and vulnerable dimensions, not only the clinical disorder that shares its name (Pincus et al., 2009; Krizan & Herlache, 2018).

Where does the concept of narcissism come from?

Freud introduced it as a technical term in On Narcissism (1914), naming a turning of libido back onto the self and distinguishing primary from secondary narcissism. The clinical theory was then developed by the object-relations and self-psychology traditions before personality psychology made it an empirical construct (Freud, 1914/1957; Kohut, 1971).

What is the difference between grandiose and vulnerable narcissism?

Grandiose narcissism is bold, dominant, self-promoting, and relatively insensitive to others; vulnerable narcissism is hypersensitive, anxious, shame-prone, and defensively withdrawn. The two are only weakly correlated and relate oppositely to traits like extraversion and neuroticism, but they share a core of entitlement and antagonism (Cain et al., 2008; Miller et al., 2011).

How did Kohut and Kernberg disagree about narcissism?

Kohut saw pathological narcissism as a developmental deficit, a fragile self left hungry for the mirroring it never received, and treated it empathically. Kernberg saw it as a defence, a grandiose structure erected over envy and aggression, and treated it confrontatively. The deficit-versus-defence opposition shaped clinical thinking for a generation (Kohut, 1971; Kernberg, 1970).

How is narcissism measured?

The Narcissistic Personality Inventory is the classic instrument but taps mainly grandiose narcissism. The Pathological Narcissism Inventory was built to capture both grandiosity and vulnerability and the oscillation between them, reframing narcissism as a dysregulation of self-esteem (Raskin & Terry, 1988; Pincus et al., 2009).

What are admiration and rivalry in narcissism?

They are the two pathways of the Narcissistic Admiration and Rivalry Concept. Admiration is agentic self-promotion that wins initial popularity; rivalry is antagonistic self-defence that produces conflict and eventual rejection. Together they explain why narcissists are liked at first and disliked over time (Back et al., 2013).

Are men more narcissistic than women?

Meta-analysis finds a robust but modest gender difference, with men scoring higher on grandiose narcissism, and the difference is largest for entitlement and exploitativeness. It is an average difference between heavily overlapping distributions, not a categorical divide (Grijalva et al., 2015).

Is narcissism one thing or several?

Most current evidence holds that narcissism is minimally two-dimensional, grandiose and vulnerable, over a shared core of entitled antagonism, and some models resolve it further into three elementary trait blocks. Whether it is a construct in its own right or a configuration of ordinary personality dimensions is the field's live debate (Weiss et al., 2019; Miller et al., 2017).
