The free IPIP-NEO-120 test, explained — what each score means

If you took the free Big Five test on Are We Friends? and now you're staring at five numbers and 30 more numbers, this is the page that translates them.

The IPIP-NEO-120 is a real psychometric instrument, not a Buzzfeed quiz. The scores are percentile ranks — they tell you where you fall relative to a normative sample of thousands of test-takers. A 70 on Openness means you scored higher than 70% of the people in the comparison sample.

Here's what each score actually says, in plain English.

Reading the percentile

The five domain scores at the top are the headline. Each is a number from 1 to 99. 50 is exactly average — half the population scores above you, half below.

Anything in the 40-60 range is essentially "typical" — there's enormous variation within that band but nothing about your personality is statistically distinctive on that domain.

60-79 is the moderately-distinctive band. You're noticeably higher (or lower, on the inverse end) than most people, but not extreme. Most "high Openness" creative-class people are actually in this range, not above 80.

80+ is genuinely distinctive — top quintile. About 1 in 5 people score this high on any given domain. 20- is the same on the low end.

95+ or 5- is rare and worth taking seriously as a defining feature of your personality. About 1 in 20 people scores this extreme.

The five domains, in order of what they predict

### Openness (O)

What it actually measures: how much you lean into the new and abstract. High = imaginative, intellectually curious, open to unconventional ideas. Low = practical, conventional, prefers the tested.

If you scored high (70+): you're probably someone who reads omnivorously, gets restless when conversations stay surface-level, and gets bored before most people in stable jobs. The Openness facets break this down further — you might be high on Imagination and Adventurousness but moderate on Artistic Interests, for example.

If you scored low (30-): you probably have strong opinions about practicality, find abstract conversations a little exhausting, and prefer to invest in things you've already proven work. This is also where most very effective operations and management people score.

### Conscientiousness (C)

What it actually measures: whether you finish things and how you handle structure. High = organized, plans ahead, reliable. Low = spontaneous, flexible, comfortable with messiness.

This is the single most studied trait in the Big Five → outcomes literature. If you scored high, you almost certainly do better at school, work, and long-term planning than your IQ alone would predict. If you scored low, you likely struggle with deadlines and follow-through but may have above-average creative output (the relationship is U-shaped — moderate is best for creativity).

### Extraversion (E)

What it actually measures: how you get and lose social energy. High = recharged by people. Low (introverted) = recharged by solitude.

The most common misreading: people think Extraversion is "outgoing-ness." It's not. Plenty of introverts are confident and articulate in social settings — they're just drained by extended exposure to people, while extraverts are fueled by it.

A high score doesn't mean you're popular or fun. It means you have more social bandwidth and you self-report happier on average. A low score means you have less bandwidth but typically deeper relationships within it.

### Agreeableness (A)

What it actually measures: how cooperative vs. competitive you are by default. High = warm, trusting, gives people the benefit of the doubt. Low = direct, skeptical, willing to disagree.

The single most surprising and well-replicated finding: high Agreeableness correlates negatively with income. The reason is straightforward: low-Agreeableness people negotiate harder, leave bad jobs faster, and are more comfortable with conflict — all of which is rewarded financially.

If you're a man and scored high on Agreeableness, you're probably leaving money on the table at work. If you scored low, you're probably making a normal amount of money but accidentally pissing more people off than you realize.

### Neuroticism (N)

What it actually measures: how reactive your nervous system is. High = feels emotions intensely, weather inside changes fast. Low = steady, doesn't fluster easily.

Of all the Big Five, this is the one most worth taking seriously about how you organize your life. High-Neuroticism people benefit enormously from external structure (consistent sleep, regular exercise, fewer dramatic life changes per year). Low-Neuroticism people can absorb chaos better but often miss social cues that the high-N people pick up automatically.

High Neuroticism is the strongest single-trait predictor of clinical depression and anxiety risk. If you scored 80+ here, paying attention to mental-health hygiene is meaningfully more important for you than for most people.

The 30 facets — the underrated half

Below the five domain scores, you'll see 30 facet scores. Each of the five domains breaks into six narrower traits. The facets are where the actual signal is.

A specific example. Two people both score 60 on Extraversion. Person A is high on Assertiveness and Activity Level but low on Cheerfulness and Excitement-Seeking. Person B is the reverse — high on Cheerfulness and Excitement-Seeking, low on Assertiveness. They have the same domain score but completely different personalities.

The facet table is what to use if you actually want to understand what your scores predict. The full facet glossary:

• Openness facets: Imagination, Artistic Interests, Emotionality, Adventurousness, Intellect, Liberalism
• Conscientiousness facets: Self-Efficacy, Orderliness, Dutifulness, Achievement-Striving, Self-Discipline, Cautiousness
• Extraversion facets: Friendliness, Gregariousness, Assertiveness, Activity Level, Excitement-Seeking, Cheerfulness
• Agreeableness facets: Trust, Morality, Altruism, Cooperation, Modesty, Sympathy
• Neuroticism facets: Anxiety, Anger, Depression, Self-Consciousness, Immoderation, Vulnerability

Every facet has its own implications for behavior, relationships, and career fit. Most people skip the facet view because it's information-dense, but if you've taken the test, the marginal time investment to read your full facet table is genuinely high-leverage.

What the scores DON'T tell you

A few important boundaries:

• The Big Five doesn't measure intelligence. Openness correlates ~0.3 with IQ, but the relationship is moderate. There are smart conventional people and unintelligent eclectic ones.
• The scores aren't destiny. They're weak predictors at the individual level — useful only at population scale. A 90 on Conscientiousness doesn't guarantee you'll be successful at work; it shifts the probability slightly upward.
• They're not a label. "INFP" is a label. "Openness 67, Conscientiousness 41, Extraversion 28, Agreeableness 72, Neuroticism 54" is a description. The Big Five is descriptive of behavior tendencies, not a category you fit into.
• They're stable but not fixed. Big Five scores correlate strongly across years (test-retest in the 0.7+ range over 5 years), but life events do shift them. Marriage shifts Conscientiousness up. Loss shifts Neuroticism up. Long-term life satisfaction shifts Agreeableness up.

What to do with your scores

A few practical implications:

1. Use them to reduce friction with people, not to label yourself. If you know your partner is high on Neuroticism, your default move during their stressed-out moments shifts. If your friend is low on Conscientiousness, you stop interpreting their flakiness as "they don't care."

1. Use them to choose environments, not to limit yourself. High Openness + low Conscientiousness should make you skeptical of careers requiring lots of unbroken focus on routine work. High Agreeableness + low Neuroticism is a great profile for nursing or teaching but maybe a poor one for litigation.

1. Use the FACETS, not just the domains. This is where the Big Five does its real work. Two people with the same domain score can be wildly different on the facets, and the facets are where your actual life happens.

1. Use them to understand your friendships. Some facet patterns (high Openness, similar Trust levels) predict easy friendships. Some (low Trust on both sides, very different Excitement-Seeking) predict friction. The facet-level matching is what we use at Are We Friends? to rank compatibility — exactly because the domain-level summary loses too much information.
