Personality

Most of us could recognize the people we love from a few lines of their writing, or from the way they react to good news. That recognizable shape, what a person tends to notice, want, fear, feel, and do, again and again over the years, is what psychologists mean by personality. The older word was character, and the two are used interchangeably here.

The Psychodynamic Diagnostic Manual (PDM-3) puts it simply: “Personality is more about who one is as a person than what disorder one has” (McWilliams & Shedler, 2026, p. 653). It includes much more than outward behavior or measurable traits: temperament, motives, fantasy life, inner conflicts, habitual ways of thinking and feeling, ways of experiencing ourselves and others, ways of attaching, and ways of coping and defending (p. 653). The same manual observes that psychological problems “may be the flip side of a person’s strengths” (p. 653).

Psychodynamic writers look for recurring themes rather than lists of traits. Nancy McWilliams points out that people tend to show both sides of whatever matters most to them: someone conflicted about closeness can be unsettled by closeness and by distance alike (McWilliams, 2011, pp. 40–41). Everyone has regular ways of experiencing and coping that make up a personality, and in most of us it is not “disordered” (p. 153). This section describes the patterns clinicians have learned to recognize, the strengths each one carries, and the places where each one can make life harder. It is a map of human variety, not a list of things wrong with people.

Style Versus Disorder

The PDM-3 starts from the idea that all people, whether healthy or troubled, have personalities and personality styles, and that “it is a mistake to conflate personality styles with ‘disorders’” (McWilliams & Shedler, 2026, p. 652). There is no clear line between the two. The word “disorder” is, in the manual’s phrase, a “linguistic convenience” for clinicians: it marks a degree of extremity or rigidity that causes significant dysfunction, limitation, or suffering to the person or to others (p. 653). One can have a narcissistic, depressive, or obsessive style without having a disorder of that kind.

McWilliams makes the same point from the clinic. The boundary between benign personality traits or styles and mild personality disorders, she writes, is “quite blurry” (McWilliams, 2011, p. 51), and “dynamics are not pathology” (p. 154). It makes sense to speak of pathology only when a person’s patterns are so stereotyped that they block growth and adaptation. Her example: one obsessive man organizes his life around thinking and takes pride in scholarship, careful planning, and good judgment; another ruminates in circles, accomplishes nothing he wants, and hates himself for it (p. 154). Same style, very different lives.

Across the psychodynamic literature and the official manuals, a handful of markers keep returning:

Rigidity
Healthy people use many ways of coping, depending on the situation; a person who meets every stress with the same move is less free. Ego psychologists linked mental health to emotional flexibility, and Wilhelm Reich’s image of “character armor” captured its opposite (McWilliams, 2011, p. 29). Even fairly healthy, neurotic-level people are “notable for their relative rigidity” in their particular sore spots (McWilliams & Shedler, 2026, p. 657).
Pervasiveness
At healthier levels the trouble tends to stay in one area, such as conflicts with authority, while other parts of life go well. At more severe levels the same patterns color nearly every relationship and setting (McWilliams & Shedler, 2026, p. 657). The DSM-5’s alternative model asks whether problems are “relatively inflexible and pervasive across a broad range of personal and social situations” (as quoted in Clark, 2025).
Suffering
Some patterns mainly hurt the person who has them; others mainly hurt the people around them. The PDM counts suffering “to self or others” (McWilliams & Shedler, 2026, p. 653).
Impairment
Does the pattern get in the way of love, work, and the rest of life? Both the PDM and the official manuals tie the word “disorder” to real limitation in functioning (McWilliams & Shedler, 2026, p. 653; Bach & First, 2018).
Capacity to reflect on it
A pattern a person can step back from and find puzzling is easier to change than one that feels like simply the way things are. Clinicians call the first “ego alien” and the second “ego syntonic” (McWilliams, 2011, pp. 28–29). Long-standing patterns can be “as invisible to the person as water to a fish” (McWilliams & Shedler, 2026, p. 654).

Context matters before any of these markers are applied. A person living under unrelenting stress can look disordered when the pattern is really a response to the situation. McWilliams describes employees and students in humiliating, “paranoiagenic” institutions whose suspicious traits faded once they left (McWilliams, 2011, p. 154), and the PDM-3 notes that under enough strain or trauma, “any of us can look borderline or even psychotic” (McWilliams & Shedler, 2026, p. 654). Some look-alikes are not personality at all. Ritualized behavior, for example, might reflect an obsessive–compulsive disorder unrelated to personality, an obsessive–compulsive style, a psychotic belief, an organic brain condition, or the repetitive behavior of the autism spectrum (p. 654).

The official manuals draw the line their own way. DSM-5-TR (2022) keeps ten categorical personality disorders, grouped into Clusters A, B, and C, and defines a personality disorder as an enduring pattern of inner experience and behavior that departs significantly from the norms and expectations of the person’s culture (Fariba et al., 2024). DSM-5 also printed an alternative, dimensional model in its Section III, which requires at least moderate impairment in self and interpersonal functioning plus one or more pathological traits (Clark, 2025). Some familiar styles have no DSM home at all: depressive personality, which the PDM-3 suggests may be the most common style in clinical practice, is absent from the DSM (McWilliams & Shedler, 2026, p. 667; McWilliams, 2011, p. 10).

ICD-11, which came into effect in January 2022 (World Health Organization, 2019), dropped personality types altogether. It rates personality disorder as mild, moderate, or severe, with optional trait qualifiers and an optional borderline pattern. Below the threshold sits “personality difficulty,” which is explicitly not a mental disorder: relatively stable problems that show up only intermittently, such as in times of stress, or at low intensity (Bach & First, 2018; Lingiardi & McWilliams, 2026, p. 5). It is the closest any official system comes to naming the space between a style and a disorder.

Two Dimensions

McWilliams once explained her work to a friend who sorted people into just two groups, the troubled and the untroubled. Psychoanalytic thinking, she replied, assumes everyone is a little irrational and asks two different questions: how much difficulty, and of what particular kind (McWilliams, 2011, pp. 43–44). Those two questions became the two axes of psychodynamic personality diagnosis, though she stresses that they cover only some of what it helps to know about any person (p. 2).

The first is personality style: the familiar configurations, such as narcissistic, obsessive–compulsive, dependent, or paranoid, that clinicians have recognized over generations and that statistical research has since confirmed (McWilliams & Shedler, 2026, p. 652). The Personality Styles page lists all fifteen described on this site.

The second is level of organization, a spectrum running from healthy through neurotic and borderline to psychotic (McWilliams & Shedler, 2026, p. 652). Here “borderline” names a level of functioning, not the DSM diagnosis. The Organization page explains the levels.

The two axes cross. In principle any style can appear at any level, which is why the PDM-3 can say that a person with a narcissistic style at a high level of organization “may be a leader or visionary,” while the same style at a low level may cause trouble in almost every part of life (McWilliams & Shedler, 2026, p. 652). The one exception is the emotionally dysregulated style, which is by definition tied to the borderline level (p. 665). People are not spread evenly across the grid: styles built on more costly defenses, like the paranoid style, turn up more often at the severe end, and those built on gentler ones, like the obsessive style, more often at the healthy end (McWilliams, 2011, p. 96). Clinically, McWilliams adds, a person’s overall level often matters more than which type best describes them (p. 97).

The PDM-3 adds a third lens: thirteen mental capacities (the M Axis), from regulating feelings and mentalizing to regulating self-esteem and finding agency and purpose, grouped into four domains and each rated on a 5-point scale (Lingiardi et al., 2026, pp. 710–712). Level of organization can be thought of as a general synthesis of these capacities (McWilliams & Shedler, 2026, p. 656). The capacities also show why two people at the same level can be quite different: one may be at the borderline level mainly because of immature defenses, another because of shaky relationships and a poorly integrated sense of self (Lingiardi et al., 2026, p. 710).

Why Describe Personality at All

For many people, McWilliams acknowledges, “diagnosis” is a dirty word. Diagnostic labels have been used to oversimplify complicated people, to keep painful feelings at a distance, to punish people who are hard to deal with, and to dress up racism, sexism, and other prejudices (McWilliams, 2011, p. 7). She quotes writers who call diagnoses “insults with a fancy pedigree” and insist that “labels are for clothes, not people” (p. 7). Her answer is that the misuse of a tool is not a reason to throw it away. Used carefully, a language for individual differences gives people a way to imagine minds that work differently from their own (pp. 7–8).

She lists five ways a thoughtful picture of someone’s personality helps in therapy (McWilliams, 2011, p. 8):

There are smaller benefits too. A working hypothesis calms the therapist, and a calmer therapist is easier to talk to. It also helps to treat any formulation as tentative; clients tend to appreciate care and humility more than certainty (McWilliams, 2011, pp. 16–17).

Her case for diagnosis is not a case for checklists. McWilliams argues that the DSM has no implicit definition of mental health, that the validity and reliability of its post-1980 editions have been disappointing, and that some of its decisions look arbitrary, such as the disappearance of the long-standing diagnosis of depressive personality (McWilliams, 2011, pp. 9–10). She also worries about a quieter social effect: saying one “has” a disorder can be a more estranged way of describing oneself, as when “I have social phobia” replaces “I am a painfully shy person” (p. 11).

McWilliams is just as clear about the limits. Once she knows someone well and the work is going well, she stops thinking diagnostically, and she suspects herself of hiding from the person’s pain if she cannot (McWilliams, 2011, p. 18). Some people simply do not fit the categories. For others, their faith, age, race, class, disability, politics, or sexual orientation matters more at first than their personality type (p. 19). “People are much more complex than even our most thoughtful categories admit” (p. 19).

She also warns readers about her own tone. Nearly everything one can say about character patterns is disputable, and many of these ideas are hard to test. She chose to oversimplify rather than obscure, and she encourages readers to outgrow her constructions (McWilliams, 2011, p. 4). The PDM-3 frames the whole enterprise the same way: “A model of personality is ultimately a form of map” (McWilliams & Shedler, 2026, p. 651), useful only if it helps someone find their way.

A Note on Labels

Psychological words tend to go sour. McWilliams traces how what DSM now calls antisocial personality disorder was “moral insanity” in 1835, then psychopathy, then sociopathy, each new term coined to be neutral and each eventually tainted (McWilliams, 2011, p. 2). A newcomer who reads “masochistic” may assume it means someone who loves pain, when the actual literature is a humane effort to understand why people keep ending up hurt despite trying hard not to (pp. 2–3). As the PDM-3 says of the term “hysteric,” there is “a difference between the term and the phenomenon” (McWilliams & Shedler, 2026, p. 685).

So this site never calls anyone “a narcissist” or “a borderline.” It speaks of people with a narcissistic style, narcissistic dynamics, or someone organized at the borderline level. A few more things to keep in mind:
