The Big Five in five minutes

Extraversion

High. People who score high on extraversion say they are the life of the party, start conversations easily and are comfortable around people they do not know. They tend to talk more than they listen, enjoy attention and feel energised by a busy room. In daily life that often shows as a wide circle of acquaintances, a preference for doing things with others, and little hesitation in speaking up. It says nothing about how deep those friendships are, how confident someone is underneath, or whether they are good company.

Low. People who score low on extraversion say they have little to say in groups, keep in the background and are quiet around strangers. They tend to prefer one or two people to a crowd, think before speaking, and find long stretches of socialising tiring rather than energising. In daily life that often shows as a small circle of close friends, a liking for time alone, and a reluctance to draw attention to themselves. It is not shyness, and it is not a lack of social skill: many quiet people are very good with others when they choose to be.

Agreeableness

High. People who score high on agreeableness say they are interested in people, feel others' emotions and take time out for them. They tend to assume good intentions, avoid conflict, and go out of their way to make others feel at ease. In daily life that often shows as being the person others confide in, giving way in arguments, and finding it hard to say no. It does not mean being a pushover, and it does not mean being liked: it describes how much weight someone gives to other people's feelings, not how well they handle them.

Low. People who score low on agreeableness say they feel little concern for others, are not much interested in other people's problems and will say what they think even if it stings. They tend to be sceptical of motives, comfortable with disagreement, and more concerned with being right than with being liked. In daily life that often shows as blunt feedback, a willingness to negotiate hard, and a small number of close relationships that run deep. It is not the same as being unkind: many low scorers are loyal and fair, just not soft.

Conscientiousness

High. People who score high on conscientiousness say they are always prepared, pay attention to details, follow a schedule and get chores done right away. They tend to like order, keep their belongings in their proper place, and feel uneasy when things are left half done. In daily life that often shows as punctuality, tidy spaces, long-term plans that get carried out, and a reputation for reliability. It does not mean being rigid or joyless, and a very high score can come with difficulty relaxing or delegating.

Low. People who score low on conscientiousness say they leave their belongings around, forget to put things back, make a mess of things and sometimes shirk their duties. They tend to work in bursts rather than steadily, improvise rather than plan, and tolerate clutter that would bother others. In daily life that often shows as deadlines met at the last minute, a flexible attitude to rules, and a knack for changing course. It is not a measure of intelligence or talent: many low scorers do excellent work when the work interests them.

Emotional stability

High. People who score high on emotional stability say they are relaxed most of the time, seldom feel blue and are not easily disturbed. They tend to take setbacks in their stride, recover quickly from bad days, and keep an even mood under pressure. In daily life that often shows as being the calm one in a crisis, sleeping well, and not dwelling on what went wrong. It does not mean feeling nothing: high scorers have the full range of emotions, they just return to baseline faster.

Low. People who score low on emotional stability say they get stressed out easily, worry about things, change their mood a lot and get upset or irritated easily. They tend to feel setbacks keenly, notice threats early, and take longer to settle after a bad day. In daily life that often shows as careful planning for what might go wrong, sensitivity to criticism, and moods that others can read. It is a tendency, not a condition: the scale measures how readily feelings arise, not whether anything is wrong, and sensitive people are often perceptive and conscientious friends.

Intellect or imagination

High. People who score high on intellect or imagination say they have a rich vocabulary, a vivid imagination, excellent ideas and are quick to understand things. They tend to enjoy abstract discussion, reflect on things, read widely and use difficult words without noticing. In daily life that often shows as curiosity, a taste for the new, and pleasure in puzzles, arguments and art. The scale measures interest in ideas and self-rated quickness, not measured ability, and it says nothing about practical sense.

Low. People who score low on intellect or imagination say they have difficulty with abstract ideas, are not interested in them, and do not have a good imagination. They tend to prefer the concrete to the theoretical, the proven to the novel, and plain words to difficult ones. In daily life that often shows as practical judgement, a liking for routine and hands-on work, and impatience with speculation. It is not a measure of intelligence: the scale asks what people enjoy and how they see themselves, not how well they think.

Internal consistency (coefficient alpha) per scale: the published figure, and the figure computed from the norm sample by the script that built the norm table, kept apart:

Coefficient alpha for each 10-item scale as reported on the IPIP key page (https://ipip.ori.org/newBigFive5broadKey.htm), accessed 3 November 2026. No test-retest figure is published there.

Cronbach's alpha from the 603322 kept rows, computed by the generating script. Published alphas are in the instrument file.

Percentiles compare you with 603,322 people (everyone in the sample) in Open-Source Psychometrics Project, IPIP Big-Five Factor Markers responses (IPIP-FFM-data-8Nov2018.zip), 1,015,342 responses collected 2016 to 2018. 1015341 rows read; 318496 dropped because more than one record came from the same IP address (IPC not 1); 93523 dropped for a response outside 1 to 5; 603322 kept. The dataset presented the same 50 items with an "I" prefix on a scale labelled 1 = Disagree, 3 = Neutral, 5 = Agree, not the IPIP accuracy labels the site uses. The country groups use the dataset's technically determined country column. No age is recorded. The dataset page states that all data are anonymous and released for general public edification.

No test-retest figure is published on the IPIP key page for these markers. Personality scores are fairly stable over weeks and months; a change of a few points between attempts is usual and does not mean you have changed.

Limits worth knowing: this is a self-report, so it measures how you see yourself, and it uses ten items per trait, so it cannot separate the facets within a trait (the 120-item version does). The comparison sample answered online and is not a representative sample of any country.
