How to read body language
Read body language in clusters and against a person's baseline — not single cues. The accurate approach, plus the myth that won't die.
Reading body language accurately means reading clusters of signals against a person’s individual baseline — not interpreting single gestures in isolation. Chase Hughes (The Ellipsis Manual, 2015) argues that one cue is noise; three aligned cues are a pattern. The difference between those two approaches is the difference between useful reading and confident misreading.
Why single cues mislead you
The popular version of body language reading goes like this: crossed arms mean defensive, avoiding eye contact means lying, touching your nose means deception. Every one of those rules fails under scrutiny, because every one of them ignores individual variation.
Some people cross their arms when they’re cold. Some avoid eye contact when they’re thinking. Some touch their face constantly, regardless of their internal state. Carol Kinsey Goman (The Silent Language of Leaders, 2011) makes the baseline argument clearly: you cannot read a deviation until you know what that person looks like at rest. Without it, you’re not reading — you’re projecting.
The fix is two-part. First, give yourself a few minutes at the start of any interaction to observe without interpreting. Notice how this specific person holds their body, where they look, how fast they speak. Second, never act on a single cue. Wait until three or more signals point in the same direction before treating the cluster as meaningful.
The 93% myth — and what Mehrabian actually said
Here is the explicit stance: the claim that ‘93% of communication is nonverbal’ is wrong, and repeating it makes you less trustworthy, not more.
Albert Mehrabian (1971) ran a narrow series of experiments on how people judge feelings and attitudes when verbal and nonverbal signals contradict each other — a specific, constrained setup. His 7-38-55 finding (words / voice tone / facial expression) applies only to that context. It says nothing about giving directions, negotiating a contract, explaining a technical problem, or most of the communication that makes up daily life. Elizabeth Stokoe (Talk, 2021) documents how thoroughly the misquote has colonized management training and self-help literature, usually in service of overselling a workshop.
This matters practically. If you believe nonverbals dominate everything, you’ll over-index on gesture and under-weight words — which is exactly backwards in high-stakes conversations where precision matters. The accurate view: nonverbal channels, especially voice and face, carry significant emotional and attitudinal information, but they work alongside words, not instead of them. Joe Navarro (What Every Body Is Saying, 2008) spends the opening chapters of his book establishing this same calibration.
The channels that actually carry signal
Not all channels are equal. Dirk Standop (Read the Face, 2019) argues the face is the richest single channel — and within the face, the eyes and the area around the mouth carry the most. Standop also notes that the two sides of the face frequently express different things at once, with the left side tending to reflect genuine felt emotion more directly than the right.
After the face, vocal tone, pace, and hesitation consistently outperform posture and gesture as predictors of authentic emotional state. Carmine Gallo’s analysis of Steve Jobs in Presentation Secrets of Steve Jobs (2010) makes this concrete: it was the deliberate pauses, the dropped pace before key phrases, and the vocal variety that created impact — not the standing-on-stage posture. Hands, head tilts, and body orientation add context, but they’re also the channels most easily managed by someone who knows they’re being watched.
The practical hierarchy: watch the face first, listen to the voice second, and treat postural signals as supporting context rather than primary evidence. This discipline makes you a significantly better reader, and it aligns with what the active listening literature recommends for attending to both channels simultaneously.
What body language can and cannot tell you
Here is where most popular treatments go wrong: they promise certainty where the evidence supports only probability.
Body language is one channel of a multi-channel signal, as Elizabeth Stokoe (Talk, 2021) argues throughout her book. A cluster of discomfort signals tells you someone is uncomfortable — it does not tell you why. They may be anxious about the topic, physically uncomfortable in the chair, distracted by something unrelated, or, yes, concealing something. Treating the cluster as a verdict rather than a hypothesis is what produces false reads and damaged trust.
The honest use of body language reading is this: let it generate questions, not conclusions. When you notice a cluster of tension signals, it’s a prompt to ask an open question, not to confront or accuse. When you notice sudden relaxation in someone’s shoulders and voice, it’s a cue that you’ve said something that landed well — worth noting, not worth announcing. And if you want to build the kind of presence that makes others comfortable being read, our guide on confident body language covers the signals worth managing in yourself.

FAQ
Is the '93% of communication is nonverbal' statistic true?
No — and it is one of the most durable misquotes in popular psychology. **Albert Mehrabian (1971)** ran studies on communicating _feelings and attitudes_ in situations where verbal and nonverbal signals were incongruent. His 7-38-55 rule (words / voice / face) applies only to that narrow context. It says nothing about communication in general. When someone gives you directions or negotiates a contract, the words carry most of the meaning. Repeating the 93% figure in any other context is simply wrong — **Elizabeth Stokoe** (*Talk*, 2021) makes this point extensively.
What does it mean to read body language in clusters?
A cluster is a group of signals that point in the same direction at the same time. A single **crossed arm** might mean cold, not defensive. A single **averted gaze** might mean thought, not deception. But crossed arms plus averted gaze plus a leaning-away torso plus a clipped voice — that cluster is harder to explain away. **Chase Hughes** (*The Ellipsis Manual*, 2015) argues clusters are the minimum unit of meaningful nonverbal reading. One signal is noise; three or more aligned signals are a pattern worth noting.
What is a 'baseline' and why does it matter?
A **baseline** is how a specific person behaves when they are comfortable and at ease. It varies by individual: some people naturally avert their eyes; others fidget constantly. **Carol Kinsey Goman** (*The Silent Language of Leaders*, 2011) stresses that you can only spot a meaningful deviation when you first know someone's normal. Without a baseline, you will consistently misread the shy person as hiding something, or the energetic person as anxious. Establish the baseline in the first few minutes of interaction — then watch for departures.
Which body language channels carry the most signal?
The **face** — specifically the eyes and the mouth — carries the richest information of all the channels. **Dirk Standop** (*Read the Face*, 2019) notes that the two sides of the face often express different things simultaneously, with the left side tending to reflect genuine emotion more directly. After the face, **vocal tone and pace** outweigh literal word choice for conveying attitude — a point Carmine Gallo documents in *Presentation Secrets of Steve Jobs* (2010). Hands and posture add context but are more easily controlled by a motivated person.
Can you tell if someone is lying from body language alone?
No — not reliably. This is the most dangerous myth in this field. **Paul Ekman's** microexpression research is real and interesting, but the claim that trained observers can detect lies at high accuracy is contested. Meta-analyses find human deception detection is barely above chance. The honest position: **clusters of stress signals** tell you someone is _uncomfortable_, not necessarily _deceptive_. They may be shy, anxious, tired, or distracted. For a deeper look at what the evidence actually supports, see our piece on [how to tell if someone is lying](/en/blog/how-to-tell-if-someone-is-lying).
What is mirroring and does it work?
**Mirroring** is the unconscious (or deliberate) matching of another person's posture, pace, and gesture. It works in two directions: people who feel rapport naturally mirror each other, and _deliberately_ adopting similar postures can create a sense of connection. **Alan Alda** describes in *If I Understood You, Would I Have This Look on My Face?* (2017) how mirroring attention made him a far better interviewer — and, in turn, helped him read the person across from him more accurately. The practical implication: slow down, match their energy, and your reading improves alongside the rapport.
How important is voice compared to words or body movement?
More important than most people assume. **Carmine Gallo** (*Presentation Secrets of Steve Jobs*, 2010) documents how Jobs's deliberate pace, strategic pauses, and vocal variety carried emotional weight far beyond the scripted words. Joe Navarro (*What Every Body Is Saying*, 2008) makes the same point: the vocal channel — pitch, speed, volume, hesitation — is harder to consciously control than posture, and therefore leaks more authentic emotional state. If you want to improve your nonverbal reading, start by listening to the **voice, not just the words**. See also our guide on [voice and tone](/en/blog/voice-and-tone).
Does body language mean the same thing across cultures?
Often not. **Joe Navarro** (*What Every Body Is Saying*, 2008) is careful to note that while some expressions — particularly the basic six emotions documented by Ekman — appear cross-culturally, many gestures are culturally specific. A thumbs-up, direct eye contact, or the meaning of personal space varies significantly by region and context. The cluster-and-baseline approach is partly valuable because it sidesteps cultural generalizations: you are comparing this person to _themselves_, not to a universal standard that may not apply.
How can I practice reading body language without misreading people?
Three habits help. First, **observe without interpreting** — watch for a few minutes before drawing any conclusions. Second, test your reads against multiple signals (the cluster rule) before acting on them. Third, treat your read as a **hypothesis, not a verdict** — check it against what you hear in words and tone before deciding. Active listening disciplines train exactly this dual-channel awareness; our guide on [active listening](/en/blog/active-listening) covers the overlap. The goal is calibration, not mind-reading — you want to be consistently less wrong, not occasionally brilliant.
What role does body language play in building trust and connection?
A significant one — in the direction most people underestimate. **Goman** (*The Silent Language of Leaders*, 2011) shows that open posture, forward lean, and sustained (not staring) eye contact signal availability and safety before a word is spoken. Mirroring, as described above, deepens this effect. The practical implication runs in both directions: reading someone else's body language makes you more attuned; managing your own makes you more trustworthy. Our guide on [body language that builds trust](/en/blog/body-language-that-builds-trust) covers the specific signals and how to use them without looking performative.
