The base dozen key techniques covert operatives use to manipulate nonverbal communication effectively for deception.

People rarely hear dishonesty – they see it. When your body contradicts your words, it’s the silent signals that betray you.

In any situation where deception or concealment is key, controlling body language is just as important as the words you choose. Mastering this tradecraft often means aligning your microexpressions, posture, and gestures with the narrative you’re spinning – whether you’re building trust with a source or diverting attention from your true intentions.


Think of body language as the subtitles to the movie you’re playing in someone’s head. It’s the unspoken part of your communication, and people rely on it to figure out whether they can trust you. If your words say one thing but your face, hands, or posture say another, the audience (the person you’re talking to) is going to believe what they see, not what they hear.

That’s why controlling your body language – your microexpressions, gestures, and even the way you breathe – is so important. When everything lines up, you come across as confident and believable, whether you’re telling the truth or spinning a story.


      Neutralizing Microexpressions

Microexpressions are those split-second facial movements that can reveal your true emotions – fear, anger, or even joy. To conceal intent, practice keeping a neutral or mild expression regardless of your emotional state. Slow blinking and slight head tilts can project calmness and openness, masking internal stress or anxiety.

PRO TIP: Practice neutralizing microexpressions in front of a mirror or record yourself reacting to emotional triggers like surprise or frustration. Focus on relaxing your forehead, softening your eyes, and keeping your mouth in a neutral position. Over time, you’ll train yourself to respond with controlled expressions, even under pressure.


      Mirroring the Target’s Movements

People naturally trust those who appear similar to them. Subtly mimic the posture, gestures, and energy of the person you’re interacting with. Keep it natural and delayed by a few seconds, so it doesn’t come off as artificial. Done right, it’s a great way to build rapport while working an angle.

PRO TIP: When mirroring, focus on subtle movements rather than copying everything. Match their tone, pace, or posture, but avoid mimicking unique gestures like scratching their face or adjusting their glasses – it’ll feel unnatural and may raise suspicion.


      Reducing Self-Soothing Gestures

Fidgeting, touching your face, or adjusting clothing can be interpreted as nervousness or dishonesty. Control these instinctive reactions by training yourself to keep your hands still or engage them in purposeful, slow movements – like gesturing to emphasize a point.

PRO TIP: If you catch yourself wanting to fidget or self-soothe, redirect that energy into controlled, purposeful movements. For example, lightly pinch your fingers together or rest your hands on a stable surface like a table or your lap. This creates the appearance of calmness while giving your body an outlet for nervous energy. Over time, practicing these techniques during low-pressure situations will make it second nature when the stakes are high.


      Maintaining Consistent Eye Contact

Too little eye contact can make you seem evasive, while too much can feel aggressive or unnatural. Strike a balance by maintaining steady but intermittent eye contact. Break it naturally by looking at your surroundings, then returning focus to the person – this gives the impression of honesty and confidence.

PRO TIP: When maintaining eye contact, follow the “triangle technique”: subtly shift your gaze between the other person’s eyes and the bridge of their nose in a triangular pattern. This keeps your focus natural and prevents prolonged stares that might feel uncomfortable or overly intense. Add occasional, natural breaks to glance to the side or nod, which helps reinforce the impression of confidence and authenticity.


      Open Hand Gestures

When trying to build trust, avoid crossing your arms or clenching your fists. Use open palm gestures, which signal transparency and invite connection. When deceiving, however, minimize over-exaggerated movements to avoid drawing attention to your hands.

PRO TIP: When using open hand gestures, keep your palms facing slightly upward or at a relaxed angle – this subconsciously signals openness and cooperation. Avoid overdoing it; exaggerated or overly dramatic gestures can make you appear rehearsed or disingenuous.


      Controlling Your Breathing Rate

Stress affects your breathing patterns, which can give you away during high-pressure situations. Practice diaphragmatic breathing (deep, controlled breaths) to maintain calmness and prevent rapid or shallow breathing from betraying nervousness.

PRO TIP: When under pressure, count your breaths in cycles of four: inhale for four seconds, hold for four seconds, exhale for four seconds, and pause for four seconds before repeating. This “box breathing” technique not only regulates your breathing but also calms your heart rate and reduces visible signs of stress, making it easier to project confidence and control in high-stakes situations.

      Purposeful Posture

Your posture can signal confidence, authority, or submission. Keep your spine straight but relaxed, shoulders back, and movements deliberate. If you’re lying or misleading, avoid defensive stances like hunching over or crossing your arms – they suggest discomfort or guilt.

PRO TIP: When standing, slightly shift your weight evenly onto both feet and avoid leaning too far in any direction – it signals confidence and stability. If seated, plant your feet firmly on the ground and keep your back straight but relaxed. Small posture adjustments can signal adaptability and confidence without coming across as rigid or unnatural. Stay intentional with your positioning to command authority without looking stiff.


      Masking Startle Reactions

Unexpected questions or events can cause involuntary reactions, such as a quick head jerk, widening eyes, or a stiffened posture. Train yourself to respond to surprises with a neutral, practiced reaction, such as calmly raising your eyebrows and nodding slightly.

PRO TIP: Practice desensitizing yourself to surprises by exposing yourself to unexpected stimuli during training. For example, have someone unexpectedly clap, drop objects, or ask curveball questions while you’re focused on a task. Over time, you’ll learn to suppress automatic startle reactions and respond with calm, controlled body language instead.


      Pacing Gestures to Speech

When trying to align your body language with a narrative, synchronize your hand gestures with your speech cadence. This creates the illusion of authenticity. Avoid hesitation or mismatched gestures, as they can appear unnatural and raise suspicion.

PRO TIP: Practice pacing your gestures with a metronome or by recording yourself speaking. Watch for mismatched timing or jerky movements. The goal is to make your gestures flow naturally with your words – subtle, not theatrical. Over time, this will help your movements feel automatic and believable, even under pressure.


      Strategic Smiling

A smile is one of the most disarming tools you can use, but it needs to match the scenario. When building trust, a soft, warm smile can create connection. When concealing intent, avoid overdoing it or smiling at inappropriate moments – it can come off as insincere.

PRO TIP: When using a smile strategically, practice the “Duchenne smile,” which engages both the mouth and the eyes. People subconsciously associate this with genuine happiness. If your smile doesn’t reach your eyes, it can come off as forced or insincere, raising red flags. Practice in the mirror until it looks natural and effortless.


      Anchoring with Props

To divert attention from your body language, anchor yourself with an object – like holding a pen, cup, or piece of paper. Using a prop can help channel nervous energy away from fidgeting and make you appear composed. Just make sure it doesn’t become a distraction or seem out of place.

PRO TIP: Choose a prop that blends naturally into the environment and fits the scenario you’re in. A coffee cup works well at a café, a pen at a meeting, or a clipboard during a walkthrough. Avoid fidgeting excessively with it – your goal is to look composed, not distracted. Use the prop to subtly draw attention away from nervous body language, like clasped hands or tapping fingers, without making it obvious you’re doing so. It’s all about using the object to project control and focus.


      Minimizing Overthinking Movements

Deliberately controlling your body language can sometimes backfire if you overthink it. Avoid robotic or overly calculated movements that might feel unnatural to observers. Blend deception into your baseline behaviors by practicing it regularly so it feels seamless.

PRO TIP: To avoid overthinking your movements, practice grounding yourself in the moment by focusing on your breathing and surroundings. A subtle trick is to slow down all your actions – whether it’s sipping from a cup or adjusting your position. Slower, deliberate movements appear natural and confident while giving you time to stay mentally in control.


The most believable lies aren’t told; they’re embodied. To deceive effectively, wear the lie like a tailored suit – it should fit you perfectly.


Whether you’re looking to inspire trust or pull off a strategic deception, controlling body language is a critical element of the game. The key isn’t to eliminate all tells – it’s to align your nonverbal cues with your narrative. Consistency is king. Practice until these techniques become second nature, and you’ll have another weapon in your tradecraft arsenal.
