Mirroring: How We Build Rapport

Overview

When we meet others for the first time, we quickly scan their body to assess whether they are positive or negative toward us — just as other animals do for survival. We do this by checking whether they move and gesture the same way we do, a process known as mirroring. We mirror each other's body language to bond, to be accepted, and to create rapport, but we are usually oblivious that we are doing it. In ancient times mirroring helped our ancestors fit into larger groups; it is also a leftover from a primitive learning method that worked through imitation.

Nonverbally, mirroring says, "Look at me; I'm the same as you. I feel the same way and share the same attitudes." It is why a crowd at a rock concert leaps up and applauds in unison, why a queue works, and why an angry mob can sweep up normally calm people. Professor Joseph Heinrich found the urge to mirror is hardwired into the brain because cooperation leads to more food, better health, and economic growth. This topic defines what mirroring is and the rapport mechanism behind it, then works through the gender and timing differences in who mirrors whom, how long-term mirroring reshapes couples, the cellular and vocal layers of synchrony, and the decision rules for using mirroring intentionally — including when mismatching breaks rapport and when copying backfires.

What mirroring is

Mirroring is the act of copying another person's body language — their gestures, posture, facial expressions, and even their voice. One of its most noticeable forms is yawning: one person starts and it sets everyone off. Robert Provine found yawning so contagious that you don't even need to see another person yawn; the sight of a wide-open mouth is enough. Far from oxygenating the body, yawning is a form of mirroring that creates rapport and avoids aggression, exactly as it does for monkeys and chimps.

A bonding and survival device

We mirror to bond, to be accepted, and to fit in — and we are usually oblivious that we are doing it. The urge is the basis on which a queue works: people willingly cooperate with strangers they will never see again, obeying an unwritten set of behavioral rules while waiting for a bus, at an art gallery, or side by side in war. Because cooperation leads to more food, better health, and economic growth, the urge is hardwired into the brain. It also explains why highly mirror-disciplined societies — the British, Germans, and ancient Romans — dominated the world for many years.

How deep it runs

Mirroring makes others feel "at ease," and it operates well below conscious control. Slow-motion video research shows it extends to simultaneous blinking, nostril-flaring, eyebrow-raising, and even pupil dilation — remarkable, because these microgestures cannot be deliberately imitated. The signal is so strong that wearing the same outfit as another woman is a mirroring no-no, while two men who turn up at a party in the same outfit could become lifelong friends.

Mirroring as a rapport indicator

Studies of synchronous body language show that people who feel similar emotions, are on the same wavelength, and are likely experiencing rapport will begin to match each other's body language and expressions. Being "in sync" begins in the womb, where our body functions and heartbeat match the rhythm of our mother, so mirroring is a state we are naturally inclined toward.

"The vibes are right"

When someone says "the vibes are right" or that they "feel right" around another person, they are unknowingly referring to mirroring and synchronous behavior. At a restaurant, a person can be reluctant to eat or drink alone for fear of being out of sync, and diners check "What are you having?" as they try to mirror their meals. It is one reason background music on a date is so effective — it gets a couple to beat and tap in time together. In early courtship, couples move with synchronous, almost dance-like movements: one begins a sentence and the other finishes it.

The cause-and-effect layer

Because of cause and effect, intentionally assuming a body-language position begins to produce the emotion associated with it. If you feel confident you may unconsciously Steeple your hands; but if you intentionally Steeple, you will both begin to feel more confident and be perceived as confident. This makes intentional matching a powerful way to create rapport, not merely a readout of rapport that already exists. The phenomenon even appears at a cellular level: heart surgeon Dr. Mehmet Oz reported that some transplant recipients took on gestures and postures of a donor they had never seen, as though the heart's cellular memory instructed the recipient's brain. Conversely, conditions such as autism remove the ability to mirror, and a drunk person's gestures fall so out of sync with their words that no mirroring can occur.

Gender and timing differences

Geoffrey Beattie at the University of Manchester found that a woman is instinctively about four times more likely to mirror another woman than a man is to mirror another man. Women also mirror men, but men are reluctant to mirror a woman's gestures or posture — unless they are in courtship mode.

Why women "see" disagreement

When a woman says she can "see" that someone disagrees with the group, she is reading the fact that the person's body language is out of sync — they are signaling disagreement by failing to mirror the group. Most men's brains are simply not equipped to register these fine mirroring discrepancies. Men and women are also wired differently to express emotion: a woman can use an average of six main facial expressions in a ten-second listening period, mirroring the speaker's emotions so closely that it can look as if the events are happening to both of them. Men can make fewer than a third of those expressions and tend to hold an emotionless mask in public — an evolutionary habit of withholding emotion to appear in control and ward off attack. Brain scans confirm men feel emotion as strongly as women; they simply avoid showing it.

What to do if you're female

The key to mirroring a man is recognizing that he signals attitudes with his body, not his face, so facial mirroring is not required. A woman should reduce her facial expressions so as not to seem overwhelming, and — most important — should not mirror what she imagines he might be feeling, which can backfire and read as "scatterbrained" if she gets it wrong. Women in business who listen with a more serious face are described by men as more intelligent, astute, and sensible. The reverse holds for men: when a man mirrors a woman's facial expressions as she talks, she describes him as caring, intelligent, interesting, and attractive.

Looking alike over time

When two people live together for years in a good relationship, they often begin to look alike, because constant mirroring of facial expressions builds muscle definition in the same areas of the face; even couples whose faces differ can look similar because they share the same smile. The link runs the other way too: Dr. John Gottman found in 2000 that marriages are more likely to fail when one partner does not mirror the other's expressions of happiness and instead shows contempt — and this affects the smiling partner even when they are unaware of it. The same unconscious pull shows up in pet choice: people tend to favor pets that physically resemble them or seem to reflect their attitudes.

Matching voices — pacing

Mirroring is not only visual. Intonation, voice inflection, speed of speaking, and even accents synchronize during mirroring to establish mutual attitudes and build rapport — a process called pacing. It can sound as if two people are singing in tune: a speaker beats time with his hands while the listener matches the rhythm with head nods. As a relationship matures, the mirroring of body positions fades as each person learns to anticipate the other, and vocal pacing becomes the main medium for maintaining rapport.

The core rule: never speak at a faster rate than the other person. People describe feeling "pressured" when someone speaks faster than they do, because speed of speech reflects the rate at which a brain can consciously analyze information. Speak at the same rate or slightly slower, and mirror their inflection and intonation. Pacing is critical on the telephone, where the voice is your only channel.

Intentionally creating rapport

The significance of mirroring is one of the most important body-language lessons available, because it is a clear way that others tell us they agree with or like us — and a way for us to tell others we like them, simply by mirroring their body language. A boss can build rapport with a nervous employee by copying the employee's posture; an up-and-coming employee may copy the boss's gestures to signal agreement. Mirroring positive gestures puts the other person in a receptive, relaxed frame of mind because they "see" that you understand their point of view.

Weigh the relationship first

Before mirroring anyone, consider your relationship with them. If a junior employee asking for a raise copies a manager who has assumed a dominant Catapult-with-Figure-Four posture, the manager can feel affronted and the employee's standing can suffer — even if the spoken words were perfectly subordinate. The same tactic, however, is effective for disarming "superior" types — accountants, lawyers, and managers who use superiority clusters around people they consider inferior. By mirroring them you can disconcert them and force a change of position. But never do it to your own boss, and never mirror a person's negative signals.

Who mirrors whom

When the leader of a group assumes certain gestures and positions, subordinates copy — usually in pecking order. Leaders tend to walk through a doorway first, sit at the end of a sofa or bench rather than the center, and take the head of the boardroom table farthest from the door. If the boss sits in the Catapult, subordinates copy in order of their importance, which lets you watch a meeting and see who "takes sides" — who will vote with you and who against. Even when leaders disagree verbally, they often keep mirroring each other, which signals mutual respect.

Teams, couples, and decisions

Mirroring is a strong strategy for a presentation team: agree in advance that when the spokesperson makes a gesture, the whole team mirrors it. This makes the team look cohesive and unnerves competitors who sense something is coordinated without being able to name it. When presenting to a couple, watching who mirrors whom reveals where the real decision-making power lies — if the woman makes the initial small movements (crossing her feet, lacing her fingers, a Critical Evaluation cluster) and the man copies, there is little point asking him for the decision, because he does not hold the authority to make it.

Mismatching to break rapport

Mirroring builds bonds, so its absence is itself a tool. We make a point of NOT mirroring people we dislike or strangers — those riding with us in an elevator or queuing at the cinema — and deliberately mismatching another person's posture, pace, or expression signals distance and withholds rapport. This is the same mechanism that lets a woman "see" a dissenter in a group: the dissenter has simply stopped mirroring. Three options exist whenever someone takes a position toward you — ignore it, do something else, or mirror it — and the choice sets whether rapport grows or stalls.

One caveat on intentional mirroring: do not do it too early in a new encounter. Awareness of mirroring strategies is now widespread, so an obvious early copy can read as manipulation rather than rapport. Used well and not too soon, mirroring still pays big dividends — people come to feel there is "something about you they like" and describe you as "easy to be with," because they see themselves reflected in you.
