If any NLP idea has solid ground beneath it, it is rapport. People open up to those they feel connected to. The question is whether deliberately copying someone is the way to build it.
What NLP teaches
NLP rapport techniques include:
- Mirroring: matching someone’s posture, gestures or expressions
- Matching: their pace, volume and tone of voice
- Pacing: joining their mood before trying to shift it
- Language matching: picking up their key words and phrases
The idea is that people like people who are like them, so being similar builds trust.
What the research says
Mimicry and liking. In a well-known 1999 study, Chartrand and Bargh found that people naturally and unconsciously mimic the posture and mannerisms of those they talk to, which they called the chameleon effect. In a second experiment, when a researcher’s assistant deliberately mimicked participants, those participants liked the assistant more and found the interaction smoother.
The relationship in therapy. A 2018 meta-analysis of 295 studies and more than 30,000 patients (Flückiger and colleagues) found a modest but reliable link between the quality of the therapist–client relationship and the outcome of therapy, with a correlation of about 0.28. The bond matters whatever the method.
Where it goes wrong
- Obvious copying feels strange. If someone notices you mirroring them, it can come across as fake or mocking.
- Natural beats mechanical. The studies looked at subtle, natural mimicry, not a scripted technique.
- Rapport is not just matching. Warmth, listening, honesty and consistency matter more than copying a posture.
- Mimicry is not a lever for control. A small boost in liking does not make anyone do what you want.
How to build rapport well
- Pay full attention. Put the phone away and listen.
- Match energy, not gestures. Be calmer with an anxious person, brighter with a flat one.
- Use their words. Repeat their key terms back to check you understood.
- Ask, then wait. Silence is allowed.
- Be reliable. Do what you said you would do.
In hypnotherapy
Hypnotherapists need rapport because expectation and trust shape responsiveness (see hypnosis series, parts 8 and 33). Most of that comes from a clear explanation, a calm voice and a client who feels respected.
The bottom line
Rapport is real and important. Chameleon-style mirroring happens naturally and may help a little, but the foundation is attention and care, which no technique can fake.
