What is personality psychology?

Personality psychology is the field within psychology devoted to individual differences: the consistent ways one person's thinking, feeling and behaving differ from another's, and from their own patterns in different periods of life. The conventional starting citation is Allport's 1937 monograph, the book that established the trait as psychology's unit for describing a person (Allport, 1937).

A working description of the field's territory comes from a review of the discipline: personality psychology studies the ways people differ that are stable enough to be worth measuring, how those differences develop and what they predict (Funder, 2001).

The field is not the same as a personality test. A test is a tool built from the field's findings; personality psychology is the research that decides what a score from one actually means. The what is personality page covers the definition of a trait itself.

What are the main approaches within personality psychology?

No single method covers everything the field wants to know, so several approaches run alongside each other.

• The trait approach. Describes people on broad, comparative dimensions such as Extraversion or Conscientiousness, built from language and questionnaires. This is the approach behind the Big Five.
• The biological approach. Looks underneath the traits, at temperament, physiology and genetics, for the machinery that produces stable differences.
• The social-cognitive approach. Studies the beliefs, goals and expectations a person carries into a situation, and how those shape what they do there, grown from the older behaviourist tradition (Funder, 2001).
• The narrative approach. Studies the story a person builds about who they have been and where they are going.

A framework for holding these together comes from McAdams and Pals, who describe personality as unfolding on three levels at once: dispositional traits, the characteristic adaptations a person builds in a particular life, and the self-defining life narrative that gives the other two levels their meaning (McAdams & Pals, 2006).

What are personality psychology's major paradigms?

A wider-angle view groups the approaches into paradigms, the larger traditions a researcher is trained into. A review of the field found several still active at once: psychoanalytic and trait approaches remain live areas of research, the older behaviourist paradigm has evolved into today's social-cognitive paradigm, the humanistic paradigm underlies much of today's cross-cultural work, and biology and evolutionary theory have reached the standing of full paradigms of their own (Funder, 2001).

That same review named two unfinished jobs: bringing the trait and social-cognitive paradigms into one account, and building up what it called a thin inventory of basic facts about how personality, situations and behaviour relate (Funder, 2001). Both are open questions, not settled ones.

What has personality psychology found?

Three findings anchor the field.

• Structure. The Big Five did not come from one study or one theory. It came from decades of lexical research, built from the words people use to describe each other, and it has survived repeated attempts by critics to replace it with something else (Goldberg, 1993).
• Stability. A quantitative review of longitudinal studies found that people keep their relative standing on a trait more as they age, from a correlation around .31 in childhood to about .54 during the college years, about .64 at age 30, and a plateau near .74 between the ages of 50 and 70 (Roberts & DelVecchio, 2000).
• Consequence. Comparing prospective longitudinal studies, personality traits predict mortality, divorce and occupational attainment at a level about as strong as socioeconomic status or measured cognitive ability predicts them (Roberts et al., 2007).

None of these findings says a trait causes an outcome by itself, and none describes one person's afternoon. They describe patterns strong enough to be worth building a field around.

How does personality psychology differ from everyday talk about personality?

In ordinary conversation, having personality usually means being lively, memorable or entertaining. Personality psychology uses the word more broadly. Every person has a personality in this sense, including the quiet, reserved person who would never be called the life of the party. What varies is the position on each dimension, not whether a dimension is present.

Everyday talk also tends to sort people into fixed types: the extravert, the perfectionist, the difficult one. The field treats each dimension as continuous, with most people clustered near the middle and few at either extreme, so a label like extravert compresses a graded position into a category that can mislead as often as it helps. Where everyday talk explains a single incident by a trait, the field treats a trait as a summary of many incidents.

The other difference is evidentiary. A claim in the field rests on a named study and a result other researchers can check, rather than on how convincing the claim feels. That standard is why the findings above carry citations.

How does Wellington measure this?

Wellington is a science-based personality assessment from Therabot Labs LLC. It measures personality as continuous traits, built on the Big Five and HEXACO models, and writes the results back as a personal report rather than a type.

The free Snapshot puts the trait approach into practice. It asks 60 questions across about 7 minutes, covering 6 dimensions, the Big Five plus Honesty-Humility, each the average of several statements. Every trait is reported as a percentile against the reference sample. The three bands, Quiet below the 30th percentile, Balanced to the 70th, and High above it, and the Portrait names built from them, exist to make the result easier to talk about; the percentile is the measurement, and it is always shown alongside. Norms are provisional while the norming sample is completed.

The Wellington Membership extends this to 90 traits, including every facet beneath the six dimensions and the 24 VIA character strengths, and continues toward all 255 traits across eight domains. This is a trait-level report, not the social-cognitive or narrative levels the field also studies. Wellington is a wellness tool for reflection, not a medical or psychological diagnosis, and it does not replace care from a qualified professional. It is not built for hiring, and you can export or delete your data at any time.

Questions people ask

What do personality psychologists actually study?

Why people consistently differ in thinking, feeling and behaving, where those differences come from, how stable they stay across a life, and what they predict, from health to occupational attainment. Some work on the trait level, some on the beliefs and goals a person brings to a situation, and some on the life stories people build to make sense of themselves (Funder, 2001; McAdams & Pals, 2006).

Is personality psychology the same as taking a personality test?

No. Personality psychology is the research field: decades of studies on structure, stability and consequence. A personality test is a tool built from that research, and the field itself is broader, also studying goals, life stories and development.

What personality psychology theories should I know?

The trait approach describes broad dimensions such as the Big Five. The three-level framework from McAdams and Pals adds characteristic adaptations, the goals and habits of a particular life, and life narratives, the story a person tells about themselves, above the trait level (McAdams & Pals, 2006).

Does personality stay stable over a lifetime?

People keep their standing relative to others more as they age, from a modest correlation in childhood to a high one after 50, though never a perfect one (Roberts & DelVecchio, 2000). Average levels of some traits still shift across adulthood, so stability is a matter of degree.

Where does Wellington fit into personality psychology?

Wellington applies the trait approach, one of several the field uses, reporting continuous Big Five and Honesty-Humility scores as percentiles rather than sorting people into types. It does not attempt the social-cognitive or narrative levels of the field, and it is a wellness tool for reflection rather than a research instrument.
