Glossary

How readily you experience unpleasant emotions — worry, irritation, low mood, embarrassment, feeling overwhelmed. It is about the frequency and intensity of negative feeling, not about being unstable or unwell.

Why we ask. It is one of the five broad dimensions that emerge whenever personality descriptions are analysed at scale, in language after language. It also predicts more life outcomes than most single measures in psychology.

What it shows. High scorers feel negative emotions more often and more strongly, and take longer to settle afterwards. Low scorers are calm, even-tempered, and less easily rattled. Neither is a verdict: high Neuroticism goes with vigilance and emotional attunement, low with steadiness and sometimes with not noticing things.

Why it matters. This is the domain where the overall number most often misleads, because its six parts can point in opposite directions. Someone can be almost entirely free of anxiety, anger and low mood and still be intensely self-conscious. The average of those describes nobody.

How much you seek out and are energised by engagement with the outside world — people, activity, stimulation, and positive feeling.

Why we ask. One of the five broad dimensions, and the one most visible to other people. It is also frequently misunderstood as simple sociability, when it is really about where your energy goes and what replenishes it.

What it shows. High scorers are drawn outward: talkative, active, cheerful, comfortable taking up space. Low scorers are not necessarily shy or unfriendly — they are simply less pulled toward stimulation, and often find it costly rather than replenishing.

Why it matters. The parts diverge more here than people expect. Someone can score low overall while being highly active and habitually cheerful — busy and content, but genuinely uninterested in crowds or thrills.

How drawn you are to novelty, complexity, abstraction, art and unfamiliar ideas, and how readily you notice your own inner experience.

Why we ask. One of the five broad dimensions, and the one most closely tied to how people think rather than how they behave. It is also the least internally coherent of the five, which is a real property of the construct rather than a flaw in the measurement.

What it shows. High scorers seek variety, tolerate ambiguity, and enjoy ideas for their own sake. Low scorers prefer the familiar, the concrete and the practical, and are often more efficient for it.

Why it matters. The overall score is easy to misread. Because the parts hang together loosely, one unusual facet can drag the whole domain and produce a description that fits badly. Read the parts before believing the summary.

How you orient toward other people — whether you assume good faith, feel their difficulties, put their needs first, and avoid claiming advantage over them.

Why we ask. One of the five broad dimensions, and the one this project exists because of. Its items ask about people in general, which turns out to be the wrong question for a lot of people.

What it shows. High scorers are trusting, considerate, straightforward and reluctant to press an advantage. Low scorers are more sceptical, more comfortable with confrontation, and more willing to prioritise their own position.

Why it matters. This is where the instrument most obviously fails people whose warmth is conditional on closeness. Someone guarded with strangers and near-unconditional with a small circle answers "I am concerned about others" and gets back an average they have never once behaved like.

How much you regulate yourself toward goals — planning, persisting, honouring commitments, thinking before acting.

Why we ask. One of the five broad dimensions, and the best single personality predictor of long-run outcomes in work, health and education.

What it shows. High scorers are disciplined, reliable and deliberate. Low scorers are more spontaneous and flexible, and less inclined to subordinate the present to a plan.

Why it matters. The overall score conflates two rather different things: keeping your environment orderly, and keeping yourself directed. Plenty of people are highly effective and thoroughly untidy, and the parts show that where the total does not.

How readily you worry, anticipate trouble, and feel tense about what might happen.

Why we ask. It separates forward-looking apprehension from other negative feelings like anger or sadness, which behave quite differently.

What it shows. High scorers scan for what could go wrong and feel it in the body. Low scorers are hard to alarm and rarely rehearse disaster.

Why it matters. Very low anxiety with high self-consciousness is a distinctive combination: unafraid of events, but acutely sensitive to being seen.

How easily you feel irritation, frustration and resentment when things go against you.

Why we ask. Anger is a separate channel from anxiety or sadness, and people vary enormously in how accessible it is to them.

What it shows. High scorers flare quickly and feel the heat of it. Low scorers rarely register anger at all.

Why it matters. A very low score cannot distinguish "does not generate anger" from "does not have access to anger". Self-report cannot tell those apart, and they are different situations.

How prone you are to low mood, discouragement and a flat sense of things being not worth it.

Why we ask. Distinct from anxiety and from anger, and one of the strongest single indicators of general wellbeing.

What it shows. High scorers feel down more often and take longer to lift. Low scorers rarely sink, and recover quickly when they do.

Why it matters. This is a personality measure, not a clinical screen. It describes a tendency, not a condition, and it cannot diagnose anything.

How sensitive you are to being observed and judged — how easily you feel exposed, embarrassed or ashamed in front of others.

Why we ask. It is the social face of negative emotion, and it behaves quite differently from the private kinds.

What it shows. High scorers are acutely aware of how they are landing, and feel shame readily. Low scorers are comparatively unbothered by being watched.

Why it matters. This facet frequently contradicts the rest of its domain. Someone can be almost entirely free of anxiety, anger and low mood and still score at the very top here — and that combination says something a single Neuroticism number completely erases.

How strongly urges pull you, and how hard they are to resist in the moment.

Why we ask. Impulse control under desire is separable from planning or discipline generally.

What it shows. High scorers find cravings hard to override. Low scorers can sit with an urge without acting on it.

Why it matters. Often confused with low Conscientiousness, but it is specifically about appetite rather than organisation.

How well you hold together under pressure, versus feeling swamped and unable to cope.

Why we ask. Coping under load is distinct from how much negative emotion you feel at rest.

What it shows. High scorers feel overwhelmed when demands stack up. Low scorers stay functional in a crisis.

Why it matters. A low score here alongside high anxiety is common and coherent: worried in advance, but steady when it actually arrives.

How readily you feel warmth toward people and show it.

Why we ask. Warmth is separable from wanting company — you can like people individually and still not want a room of them.

What it shows. High scorers connect easily and make others comfortable. Low scorers are more reserved, which is not the same as cold.

Why it matters. This is one of the facets most likely to depend on who the other person is, which is precisely what a single score cannot show.

How much you want to be around other people, and in what numbers.

Why we ask. It is the clearest "crowd or no crowd" facet, and it separates cleanly from warmth.

What it shows. High scorers seek company and find it energising. Low scorers prefer smaller groups or solitude, and find crowds depleting.

Why it matters. A crowd of strangers and a room of close friends are plainly different experiences, and standard items rarely say which they mean.

How readily you speak up, take charge and make your position felt.

Why we ask. Social dominance is separable from sociability — quiet people are often highly assertive.

What it shows. High scorers lead, direct and state their view. Low scorers stay in the background and let others set direction.

Why it matters. Frequently confused with confidence. It is about taking up space, not about self-belief.

How fast you live — pace, busyness, and how much you keep going.

Why we ask. Sheer energy is distinct from sociability, and it is one of the better predictors of what a day actually looks like.

What it shows. High scorers keep many things moving and dislike idleness. Low scorers work at a more measured pace.

Why it matters. High Activity with low Gregariousness is a very common and very underdescribed profile: constantly busy, rarely at a party.

How much you crave stimulation, risk and intensity.

Why we ask. Thrill-seeking is separable from every other part of Extraversion, and it varies enormously.

What it shows. High scorers want noise, speed and novelty. Low scorers find that unpleasant rather than exciting.

Why it matters. A low score does not mean a narrow life. It means the appeal of an intense experience is not the intensity itself.

How readily you feel positive emotion — joy, enthusiasm, amusement.

Why we ask. Positive feeling is not simply the absence of negative feeling; they are separate systems.

What it shows. High scorers laugh easily and feel good often. Low scorers are more sober in tone, without necessarily being unhappy.

Why it matters. Can sit surprisingly high alongside low Gregariousness — cheerful, and still not wanting company.

How much you live in invented worlds, daydreams and possibilities.

Why we ask. Fantasy is separable from intellect and from artistic taste.

What it shows. High scorers have rich inner lives and elaborate freely. Low scorers stay with what is actually in front of them.

Why it matters. A low score is compatible with enormous creativity — many makers map reality rather than invent alternatives to it.

How much beauty and artistic experience matter to you.

Why we ask. Aesthetic responsiveness is one of the clearest and most stable parts of Openness.

What it shows. High scorers are absorbed by art, music and design. Low scorers are unmoved by them, which is not the same as unable to appreciate them.

Why it matters. Measures how much aesthetics move you, not how much you know about them.

How aware you are of your own feelings, and how readily you express them.

Why we ask. Access to your own inner states is separable from how strong those states are.

What it shows. High scorers notice and name what they feel. Low scorers are less aware of their own emotional weather and express it less.

Why it matters. A very low score can drag the whole Openness domain down while the other five parts sit near average — one of the most common ways this domain misleads.

How willing you are to try unfamiliar things and change your routines.

Why we ask. Behavioural novelty-seeking is separable from intellectual or aesthetic openness.

What it shows. High scorers prefer variety. Low scorers prefer what they know works.

Why it matters. About actions rather than ideas. People are often high on one and low on the other.

How much you enjoy abstract ideas, argument and thinking for its own sake.

Why we ask. Intellectual appetite is separable from intellectual ability, and only the appetite is measured here.

What it shows. High scorers enjoy theory and debate. Low scorers prefer the concrete and the applicable.

Why it matters. This is emphatically not an intelligence measure. It asks what you enjoy, not what you can do.

How readily you question authority, tradition and inherited arrangements.

Why we ask. Readiness to re-examine received values is part of openness to experience.

What it shows. High scorers challenge convention. Low scorers value continuity and established ways.

Why it matters. Despite the name, this is about disposition toward tradition rather than party politics.

Whether you assume other people mean well.

Why we ask. A basic stance toward others that shapes almost every interaction before it begins.

What it shows. High scorers assume good faith. Low scorers assume self-interest and stay watchful.

Why it matters. One of the facets most likely to depend on who is being trusted — which is exactly what this project measures.

How straightforward you are — how little you use pretence, flattery or manipulation.

Why we ask. Candour is separable from warmth. Blunt people can be kind, and charming people can be evasive.

What it shows. High scorers are frank and dislike guile. Low scorers are comfortable with strategic presentation.

Why it matters. This reads as a conduct rule rather than a feeling, which is why we predict it stays roughly constant regardless of who you are dealing with.

How much you find helping others rewarding rather than costly.

Why we ask. It distinguishes helping that comes from wanting to from helping that comes from obligation.

What it shows. High scorers find helping fulfilling. Low scorers find it draining, or do it for other reasons.

Why it matters. The facet that motivated this whole project. Its standard items ask about people in general, so someone guarded with strangers and unconditional with a small circle gets back an average that describes neither.

How far you go to avoid friction and accommodate others in a disagreement.

Why we ask. Conflict behaviour is separable from how warmly you feel toward people.

What it shows. High scorers yield and smooth things over. Low scorers hold their position.

Why it matters. Another conduct facet, predicted to stay steady across relationships — which makes it a useful control on whether the other facets really do change.

How reluctant you are to claim you are better than other people.

Why we ask. Self-presentation is worth measuring in its own right, and it affects every other score.

What it shows. High scorers are uncomfortable claiming superiority. Low scorers state their strengths readily.

Why it matters. A very high score systematically deflates every self-descriptive item on the test. Someone deeply uncomfortable claiming excellence will answer "moderately" where an equally capable person answers "very", so their true standing on other traits is probably higher than reported.

How much you feel other people’s difficulties as if they were partly your own.

Why we ask. Feeling with someone is separable from acting for them — and the two often come apart.

What it shows. High scorers are moved by suffering. Low scorers register it without being pulled by it.

Why it matters. Low Sympathy alongside high Dutifulness is a specific and common profile: consistent care driven by obligation and principle rather than by vicarious feeling.

How capable you believe you are of handling what comes.

Why we ask. Belief in your own competence predicts persistence independently of actual skill.

What it shows. High scorers expect to manage. Low scorers doubt they will.

Why it matters. A belief, not a measurement of ability. The two correlate, but not perfectly.

How much you keep things organised, tidy and structured.

Why we ask. External order is separable from self-direction — and this is the split people most often miss.

What it shows. High scorers keep systems and surfaces in order. Low scorers tolerate mess.

Why it matters. The most commonly misread facet in the domain. Plenty of extremely disciplined, effective people are thoroughly untidy.

How strongly you feel bound by obligations and commitments.

Why we ask. Obligation is a distinct motive from ambition or from affection.

What it shows. High scorers keep their word as a matter of principle. Low scorers treat commitments more flexibly.

Why it matters. High Dutifulness with low Sympathy describes caretaking driven by principle rather than feeling — two very different reasons for identical behaviour.

How hard you push toward goals and standards you set yourself.

Why we ask. Ambition is separable from discipline. Some people want a great deal and struggle to execute.

What it shows. High scorers set demanding aims and work toward them. Low scorers are content with sufficient.

Why it matters. Measures drive, not accomplishment. The two are related but far from identical.

How reliably you start and finish things without external pressure.

Why we ask. The ability to sustain effort is the part of Conscientiousness that best predicts outcomes.

What it shows. High scorers begin and persist. Low scorers put things off and stall midway.

Why it matters. This, not Orderliness, is the facet that carries most of the domain’s predictive power.

How much you think before you act.

Why we ask. Deliberation is separable from discipline. Careful people are not always persistent, and vice versa.

What it shows. High scorers weigh consequences first. Low scorers decide quickly and adjust later.

Why it matters. Neither end is better. Deliberation costs speed; speed costs accuracy.

The share of a comparison group who scored below you. The 70th percentile means you scored higher than about 70 of every 100 people in that group.

Why we ask. A raw score means nothing on its own. Twelve out of twenty is only interpretable against what other people scored.

What it shows. Where you sit relative to a specific, named group of people — never relative to humanity in general.

Why it matters. This is the most misread number in personality testing. It is not a percentage of the scale, and it is not a grade. It is also only as meaningful as the group behind it, which is why we always say who that group is and how many people are in it.

The range your true score is probably in, shown as a band around the point estimate.

Why we ask. A trait measured with four items carries real measurement error. Reporting a single number claims a precision the data does not have.

What it shows. How much the number could move if you took the test again without actually changing. A wide band means we genuinely cannot tell whether you are at the 60th or the 85th.

Why it matters. Almost no other personality test shows this. On a four-item facet the band is not a hedge — it is the finding. "94th percentile" honestly means "somewhere in the top quarter, probably".

The specific set of people your score is measured against, usually matched on age and on the group you chose.

Why we ask. Personality scores shift with age and differ between groups, so an unmatched comparison quietly mixes those differences into your result.

What it shows. Who exactly you are being placed among, and how many of them there are.

Why it matters. A percentile without a stated comparison group is close to meaningless, and three different tests will give you three different numbers without ever telling you why. We label every one.

How consistently a set of items measures the same thing, on a scale from 0 to 1. Usually reported as Cronbach’s alpha.

Why we ask. It determines how much confidence any single score deserves, and it varies a lot between traits.

What it shows. Higher values mean the items agree with each other, so the score is more stable. Our facets run from about .63 to .88.

Why it matters. This is the direct link between the statistics and what you see: lower reliability produces a wider confidence band. It is why some of your facets are measured more precisely than others.

The unadjusted total from the items themselves — for a facet, the sum of four answers after reverse-keyed items are flipped.

Why we ask. It is the actual measurement. Everything else is derived from it.

What it shows. Where you fall on the scale itself, before any comparison to other people.

Why it matters. Shown alongside every percentile so nothing is hidden behind a transformation. If our comparison group is wrong, the raw score still stands.

Some items are written so that agreeing counts against the trait rather than for it. Those answers are flipped before scoring, so a 5 becomes a 1.

Why we ask. Without them, someone who agrees with everything would score high on every trait automatically.

What it shows. In the item drill-down, reverse-keyed items are marked, and you can see both what you answered and what it counted as.

Why it matters. It is also what makes it possible to detect people who are agreeing without reading — a check we run on every submission.

Whether the narrow traits inside a broad one agree with each other, or contradict each other.

Why we ask. A broad score is the average of its parts. When the parts disagree sharply, that average describes a person who does not exist.

What it shows. When coherence is low, we de-emphasise the broad score and lead with the parts instead. When it is very low, we do not show the single number at all.

Why it matters. No other test does this. Someone can be at the 7th percentile on Neuroticism overall while sitting at the 94th on Self-Consciousness — and being told "you are not neurotic" would erase the single most informative thing in their profile.

Habits in how you use the scale rather than what you actually think — agreeing with most things, or always choosing the extremes, or staying near the middle.

Why we ask. These habits shift every score on the test, in a way the raw numbers cannot show.

What it shows. Whether your profile needs reading with a particular caution attached.

Why it matters. The clearest example is Modesty. Someone deeply uncomfortable claiming to be better than others will answer "moderately" where an equally capable person answers "very" — so their real standing on almost everything is probably higher than reported.

How your expression of a trait changes depending on how close you are to the person involved.

Why we ask. Standard tests ask about "people in general" and return one number. For many people that averages across a difference that is the most important thing about the trait.

What it shows. A flat line means you are the same whoever you are with. A slope means you taper. A sharp step means there is a boundary, and it matters which side of it someone is on.

Why it matters. Two people with identical Altruism scores can be completely different: one consistently moderately helpful to everyone, the other near-zero toward strangers and near-total inside a small circle. No existing test can tell them apart.

One of four levels of closeness we ask about: your inner circle, your friends, acquaintances, and strangers.

Why we ask. Four ordered points let us see the shape of a change, not just that a change happened. Two points would only give a difference, and differences between two noisy measurements are unreliable.

What it shows. The same behaviour, asked about four times, with only the person on the other end changing.

Why it matters. The middle rings matter more than they look. "Acquaintances" is concrete and distant at once, which lets us check whether a gradient is real or just an artefact of thinking more vaguely about people further away.

How steeply a trait falls off as people get less close to you.

Why we ask. It is the single number that best summarises the shape of a gradient.

What it shows. Larger values mean the trait is more conditional on closeness.

Why it matters. We report this combined across traits rather than for any single one, because a single facet’s slope is measured too imprecisely to say anything about a person on its own.

A sharp drop between two adjacent rings, rather than a gradual decline — a step rather than a slope.

Why we ask. A step function is exactly the pattern a single average misrepresents most badly, because the average sits at a level the person rarely actually acts at.

What it shows. That there is a boundary, and where it falls.

Why it matters. We only name a cliff when we are reasonably confident it is real. A four-point curve always looks like it has a shape, and saying so when it does not would be inventing a story from noise.

We did not find a difference between how you answered about the four groups — and separately, we could not show there is no difference. Those are two different statements, and this phrase means only the first.

Why we ask. Not finding something is weak evidence at the best of times, and this instrument asks only three statements per group. Failing to detect a gradient is exactly what you would expect whether you have no gradient at all or a modest one the measurement cannot resolve. Reporting those two as the same thing would be the most common way this site could mislead you, simply because it is the most common result.

What it shows. That your four points sit close enough together that the difference between them is inside the measurement error. Alongside it we show the size of gradient we could still have missed — if that number is large, the result is telling you about the instrument rather than about you.

Why it matters. The honest version of "you are the same with everyone" requires positive evidence, not the absence of evidence, and at this instrument length we can almost never supply it. So we say what we actually found. If your points look flat and the bound beside them is small, that is close to consistency; if the bound is wide, the flat line means very little.

Generated numbers standing in for real respondents while the site is being built.

Why we ask. The charts, comparisons and confidence intervals have to be built and checked before anyone has taken the assessment.

What it shows. Nothing about real people. Every figure derived from it is fabricated.

Why it matters. Whenever the preview banner is showing, no number on the site is a finding. It is there so the design can be judged, not so the results can be believed.

How far your five scores sit from average, taken together rather than one at a time. It is the straight-line distance from the middle of the population to where you are, measured in standard deviations.

Why we ask. A five-letter code throws away everything except which side of the middle each trait fell on. Someone at the 51st percentile and someone at the 99th get the same letter, and the code cannot tell you which one you are. Strength is the part the letter discards.

What it shows. A high value means several of your traits are a long way from typical. A low value means you are close to the middle across the board — which is the commonest shape a person comes in, not an absence of personality.

Why it matters. It is reported against everyone else’s strength, not against zero. Distance from the middle piles up across five traits, so the typical person is already some way out; measuring from zero instead would tell almost everybody they were unusual, which is flattery rather than measurement.

How evenly your distance from average is spread across the five traits. High when all five are extreme by roughly the same amount, low when one trait carries almost all of it.

Why we ask. A type is a corner of the space — a direction in which every trait is extreme at once. Your profile points somewhere, and the question a type is trying to answer is how close that direction is to a corner.

What it shows. A high value means the type name describes the whole of you, because all five traits agree about how far out you are. A low value means one or two traits dominate, and the other letters are along for the ride even if each is individually firm.

Why it matters. This is the number that catches the failure a five-letter code cannot report. Someone at the 95th percentile on one trait and average on the rest gets five confident letters from any type system, and only this says that no corner describes them well. Strength and direction quality disagree often, and both are shown rather than averaged into one comfortable figure.

The probability that all of your letters would come out the same if you took the test again — computed from the confidence interval on each trait, not from a retest.

Why we ask. Roughly half of people get a different code from a type test a few weeks later, and no type test warns them. Every letter here already carries an interval saying how much room the true score has to sit on the other side of the middle, so the warning is available for free.

What it shows. Each letter has its own probability of holding. Multiplying them gives the chance the whole code survives. Five firm letters can reach the high eighties; two soft ones can drag it under a third.

Why it matters. The figure is usually humbling, and that is why it is printed. It assumes the five traits are independent, which slightly understates the true probability, so treat it as a floor. A code is a memorable summary of the numbers above it, never a category you belong to.
