What is the Big Five personality test?

The Big Five describes personality with five broad traits: openness, conscientiousness, extraversion, agreeableness and emotional stability (its opposite is called neuroticism). Each is a scale, not a type. This test uses the 50-item Big-Five markers from the International Personality Item Pool, a free, public-domain set of statements built for research [1] [2].

Quick facts

  • What it measures: how you describe yourself on five broad traits, each from 10 statements.
  • The statements: the IPIP 50-item Big-Five factor markers by Lewis Goldberg, free for anyone to use [1] [2].
  • Your result: a score from 0 to 100 for each trait: 0 if you gave the lowest possible answers, 100 if you gave the highest.
  • No type: the Big Five gives five scores, not a four-letter type. Most people sit near the middle on most traits.
  • Stable but not fixed: traits are fairly stable in adults, and on average people become more conscientious, agreeable and emotionally stable as they get older [3].

How the test works

  1. Read a statement. For example, "I am the life of the party."
  2. Choose how well it describes you, from "Very inaccurate" to "Very accurate". Describe yourself as you generally are now, not as you would like to be.
  3. Get your profile. Each trait comes from 10 statements; some are reversed, so agreeing with "I keep in the background" counts towards lower extraversion.

There are 50 statements and nothing is timed. Your answers are scored on our server and saved to build comparisons; our privacy policy says what is kept.

How to read your result

  • Openness (in this item set: intellect and imagination): enjoying ideas, abstract thinking and imagination.
  • Conscientiousness: being organized, careful and reliable, and following through.
  • Extraversion: being outgoing, talkative and energized by company.
  • Agreeableness: being warm, caring and considerate of others.
  • Emotional stability: staying calm and even-tempered. Its opposite end, neuroticism, means feeling stress, worry and mood changes more strongly.

No end of a trait is better than the other: each fits some situations and goals better than others. A score of 70 means your answers sat 70% of the way from the lowest to the highest possible answers. It is not a percentile and not "70% extraverted".

We don't show percentiles yet. No large, published comparison data exists for this exact set of 50 statements, and the people who run the item pool advise against borrowing numbers from other questionnaires [7]. Once enough people have taken the test here, we can compare your answers with theirs.

What research has found

  • The five keep turning up. When researchers analyse the words people use to describe each other, five broad groups appear again and again, in many languages [1] [4].
  • Traits relate to life outcomes, modestly. In a large check of 78 earlier findings, most links between traits and outcomes such as health, relationships and work held up in new samples, but were usually smaller than first reported [5].
  • Personality changes slowly. Across 92 studies, people became more conscientious, agreeable and emotionally stable from young adulthood into middle age [3].
  • Both genes and life play a part. In a review of twin and family studies, about 40% of the differences between people's traits were linked to genes [6].

What this test can and can't tell you

This is a self-report: it shows how you see yourself today. Mood, how you read a statement and how you compare yourself with others all affect the answers, so taking it again can shift each trait a little. It is not a clinical or hiring test, and it says nothing about mental health. Compare with friends for fun, and keep in mind that two people's scores only mean something if both answered honestly.

Frequently asked questions

Is this Big Five test accurate?

The 50 statements are a well-studied research set. Each trait's 10 statements hang together well: their reliability (Cronbach's alpha) is .79 to .87 [7], and they match longer Big Five questionnaires closely [1] [2]. Your result is still a self-description, so it is as accurate as your answers. Taking it twice a few weeks apart usually gives similar results.

What is the difference between the Big Five and 16Personalities or Myers-Briggs?

The Big Five measures five traits on scales and is the model most personality research uses [4]. Type tests such as the Myers-Briggs sort people into categories. A trait score tells you how much of a trait you describe, instead of putting you in a box.

Why is it "emotional stability" and not "neuroticism"?

They are two names for the same trait, seen from opposite ends. The IPIP item set scores it as emotional stability [2], so a high score means calm and steady, and a low score means more stress and mood changes (high neuroticism).

Can my personality change?

Yes, slowly. On average, conscientiousness, agreeableness and emotional stability rise through adulthood [3]. A single result is a snapshot of how you see yourself now, not a fixed label.

Is the Big Five personality test free?

Yes. The test and your full result are free: no sign-up, no email, no payment, and nothing is held back for a "full report". We save results to build comparisons, as our privacy policy explains.
