What is openness to experience?

Openness to experience is the Big Five personality trait that describes how drawn you are to new ideas, art, feelings and ways of living. People high in it tend to be curious, imaginative and quick to question the usual way of doing things. People low in it tend to be practical and grounded, and they know what they like.

Neither end is the better one. High openness can look like a mind that never sits still. Low openness can look like someone who actually finishes what's in front of them. Most people sit somewhere in the middle, curious about some things and quite settled about others.

What openness actually covers

Openness is broader than "likes travel" or "has unusual taste in music". It tends to bundle a few related habits:

• Imagination: you drift into daydreams, what-ifs and possible futures.
• Aesthetic response: a song, a building or a view can genuinely move you.
• Curiosity about ideas: you enjoy a puzzle or a theory for its own sake.
• Comfort with the unfamiliar: a new food, a new city or a new routine sounds fun rather than tiring.
• Willingness to rethink: you can hold a belief loosely and turn it over.

You can be high on some of these and not others. A software engineer might love abstract ideas and have zero interest in poetry. A painter might be deeply moved by colour and bored stiff by theory.

How openness shows up

At work

If you lean high, you probably enjoy the early stage of a project, when anything is possible. You may be the person who asks why a process exists at all. You tend to pick up new tools fast and connect ideas from unrelated fields. The trade-off is that the fortieth repetition of a task can feel like wading through mud.

If you lean low, you tend to value what already works. You bring realism to brainstorms and can spot the idea that looks clever on a whiteboard and falls over on a Tuesday afternoon. Clear expectations and proven methods help you do your best work. Sudden pivots can feel like a waste of good effort, and that's often a fair call. Career interests overlap here too: the investigative career type and the artistic career type both tend to attract people who enjoy exploring.

In love

Open partners tend to see a relationship as something to keep discovering. They suggest the weird weekend away and want to talk about what a film really meant. Less open partners often show love through reliability: the same Sunday walk, the favourite cafe, the rituals that make a life feel like yours. Couples with different levels can be great for each other, as long as the adventurous one doesn't treat routine as boring and the steady one doesn't treat every new idea as a threat.

With friends

High-openness friends bring the odd documentary, the new restaurant and the 11pm conversation about whether free will exists. Low-openness friends are the ones you can call and know exactly what you'll get. They remember your order. They keep the tradition going for fifteen years. Most friendship groups are better for having both.

Strengths and watch-outs

If you lean high, your strengths include creativity, adaptability and an ability to see a problem from an angle nobody else tried. The watch-out is starting more than you finish, or dismissing what's tried and true because it's familiar. A simple fix: for every new idea you chase, name the one thing you'll keep going with. Pairing openness with some conscientiousness and follow-through is where ideas turn into something real.

If you lean low, your strengths include focus, consistency and common sense. You tend to be good at protecting what's working. The watch-out is saying no before you've looked properly. A useful habit is the small experiment: try the new thing once, for a fixed time, and then decide. You keep your judgement and you get better information.

How to work with someone high or low in openness

Someone high in openness

• Give them the why, and room to shape the how.
• Let them explore first, then agree on a point where exploring stops.
• Don't read their questions about a process as an attack on you. It's usually just curiosity.
• Help them turn ideas into next steps by asking, "What would we do on Monday?"

Someone low in openness

• Lead with what stays the same before you explain what changes.
• Bring evidence and concrete examples, not just a vision.
• Give them time to warm up to a new idea. A first "no" isn't always a final one.
• Value their reality checks out loud. They often save the team from expensive detours.

If your colleague also tends to yield or compromise in a disagreement, make sure the quiet objection gets said. It often holds useful information.

Research notes

Openness is one of the five broad factors in the Big Five model of personality. Here's what the research suggests, and where to be careful.

• Creativity. McCrae (1987) tracked 268 men and found that tests of divergent thinking, taken years earlier, were consistently linked to openness, and not to the other four traits. Feist's (1998) meta-analysis found that creative people, on average, tend to be more open and less conventional. These are group-level patterns: high openness doesn't guarantee creative output, and low openness doesn't rule it out.
• Learning at work. In Barrick and Mount's (1991) classic meta-analysis, openness and extraversion both predicted how well people did in job training across occupations. That's a narrower finding than "open people do better at work".
• Change over a lifetime. Roberts, Walton and Viechtbauer (2006) pooled 92 samples. On average, openness rose in adolescence and fell in old age. So your score isn't fixed, and averages say little about any one person. Our article on whether your personality can change goes further.
• Who sees it best. Vazire (2010) found that friends were better than the person themselves at judging traits related to intellect, which sit close to openness. That's a good argument for asking people who know you, which is the idea behind Second Sight.

Find out where you sit

Reading about a trait gets you a rough sense. Measuring it tells you where you actually land, on openness and the other four traits together. Take the Core Personality Expedition, which uses public-domain IPIP items, to see your own map. It's a starting point for curiosity, not a verdict.
