What the Big Five Says About Two People Together

Why there is no Big Five compatibility score

The Big Five places each person on five separate ranges. The five traits are measured separately, and a person's place on one range does not decide their place on the other four.

Adding five separate results into one number mixes together things that have nothing to do with each other. Two couples could get the same number for opposite reasons. One couple might match on how social they are and differ on how much they plan. The other couple might be the reverse. Those two couples would argue about completely different things.

A single number also cannot point to a moment. A result that says two people differ on planning can explain why one person was packed on Thursday and the other person was still packing on Saturday morning. A score of 72 cannot explain anything.

The five traits, side by side

Each trait has two ends, and neither end is the better one. For each trait below, the example shows what a difference between two people can look like.

• Extraversion, from Introversion to Extraversion. At a party, one person is ready to leave after an hour and the other person is just getting started.
• Agreeableness, from Directness to Warmth. When a friend asks for feedback on a business idea, one person names the problems first and the other person starts with what works.
• Conscientiousness, from Spontaneity to Structure. On a trip, one person has a printed schedule and the other person wants to see what the day brings.
• Emotional Stability, from Sensitivity to Steadiness. After a tense meeting, one person replays it all evening and the other person has moved on by dinner.
• Openness to Ideas, from Practicality to Imagination. Planning a kitchen remodel, one person asks what it will cost and the other person sketches three layouts nobody asked for.

When two people are far apart on a trait

A big difference on one trait tends to show up as the same small friction, over and over. Two roommates far apart on Conscientiousness might both be annoyed every Sunday. One roommate wants the week's chores on a list, and the other roommate does the dishes when the sink is full.

A difference like that often helps the pair as much as it costs them. The roommate who likes structure makes sure the rent gets paid on time. The spontaneous roommate is the one who says yes when a friend calls with a last-minute plan. Each person handles something the other person would skip.

The useful move is to name the difference out loud. Once both roommates know the Sunday friction comes from a real difference in how they each work, the argument tends to shift from whose way is right to how to split the week.

When two people land close together

Two people who land close together on a trait tend to find that part of life easy. Two business partners who both lean toward Structure rarely argue about deadlines, because both of them already care about deadlines.

The catch is that neither person pulls the other way. Two partners who both lean toward Structure may plan every quarter in detail and never leave room for an opportunity that shows up mid-quarter. Neither partner notices the gap, because neither partner is the one who would have filled it.

So a shared position is worth a conversation too. The question is not whether the two people agree, since they do. The question is what neither person is watching for.

What a Big Five comparison does not tell two people

A Big Five comparison describes how two people answered a set of questions at one point in time. The comparison has limits, and knowing the limits makes the results easier to use well.

• The comparison does not predict whether a relationship, friendship or business will last.
• The comparison does not say which person is easier to live or work with.
• The comparison does not measure how two people feel about each other, how they handle money, or what they want out of life.
• The comparison can shift over time, because each person's results can shift over time.

How to read a Big Five paired report together

A paired report works best as the start of a conversation. A few habits help two people get more out of the first read.

• Each person reads their own result first, so neither person meets their own result for the first time while the other person is watching.
• Pick one difference to talk about, not all five traits in one sitting.
• Tie the difference to a recent, specific moment, like last weekend's plans or yesterday's meeting.
• Ask what the difference is like from the other side, before either person explains their own side.

How to get a Big Five paired report

Taking the Big Five at selfwyse is free, and nobody needs an account to start. At the end, the results page has a link to send to one other person.

The second person takes the Big Five for free and keeps their own result. Once both people have finished, both get a free paired report that places the two results on each of the five traits. A more detailed paired report is available as a paid upgrade.

Common questions

Is there a Big Five compatibility test?

Not in the sense of a test that returns one fit score. Two people can each take the Big Five and compare their results trait by trait, which shows where the two are alike and where the two differ.

Which Big Five trait matters most for two people?

No single trait matters most for every pair. The trait that matters most depends on what the two people do together. Roommates feel Conscientiousness in the kitchen every day, while two friends who meet once a month may barely notice it.

Is it better for two people to have similar Big Five results?

Neither similar nor different results are better. A similar result on a trait usually makes that part of life easier and leaves a shared blind spot. A different result usually brings more friction and covers more ground.
