You’re leading a meeting, scanning the room (or the Zoom grid). You notice someone with their arms crossed. Another person hasn’t looked up from their notes. Someone else hasn’t spoken in ten minutes.
Your gut reaction: They’re disengaged. Something’s wrong.
Here’s the truth: You can’t trust body language to tell you how people feel—especially when it comes to trust. Relying on it can lead to faulty assumptions, broken connections, and a team that feels misunderstood.
Let’s talk about why.
We’ve been taught that nonverbal cues are universal indicators of mood, trust, or engagement. Folded arms mean resistance. Limited eye contact means discomfort. Silence means disengagement.
But Interaction Adaptation Theory—and basic human diversity—tells us this is oversimplified. What you think you see often has nothing to do with trust or connection.
People’s nonverbal behaviors are shaped by individual, cultural, and neurodivergent differences:
Real World Example: A team member on Zoom looks away and doesn’t make eye contact. A facilitator assumes they’re uninterested. In reality, the person is neurodivergent and listening more deeply without the distraction of direct gaze.
The result? The facilitator’s incorrect assumption strains trust further.
Crossed arms, quiet responses, or stillness don’t necessarily mean disengagement—they might mean caution. When people don’t yet feel psychologically safe, they’re often:
The Problem: When facilitators treat these behaviors as evidence of resistance, they often double down—cold calling, pushing for participation, or trying to “break the ice.” This pressure creates more discomfort, not less.
Context matters. Someone folding their arms in a freezing conference room is not signaling distrust. Someone staying quiet in a room where the loudest voices dominate may not feel safe speaking up—but it’s not their body language that’s the problem.
Interaction Adaptation Theory explains that behavior patterns (like matching tone or synchrony) happen within boundaries of trust and safety. Without psychological safety, people default to behaviors that protect them—like stillness, silence, or minimization.
If you misinterpret these protective actions as disengagement, you’re mistaking survival for resistance.
If you can’t rely on body language, how do you know if trust exists on your team? You look at observable patterns of behavior over time.
Here are three reliable indicators of trust:
Participation Patterns
Example: In a meeting, instead of asking people to share verbally, ask them to post ideas on a Miro board. It reduces pressure and still gathers everyone’s voice.
Willingness to Ask for Help or Clarification
Feedback Dynamics
Instead of scanning for crossed arms or silence, focus on behaviors that truly reflect trust:
Stop interpreting body language as a signal of trust—or lack of it. By focusing on observable actions and creating low-risk opportunities for engagement, you build trust instead of breaking it.
Reading body language feels intuitive, but it’s often misleading. To build real trust, you need to look beyond physical cues and create spaces where people feel safe to contribute—however they choose to show up.
Because trust isn’t found in crossed arms or eye contact. It’s found in what people do when they know they’re safe.
This post is the first in a series about why traditional icebreakers often do more harm than good. In the next post, I’ll share practical strategies leaders and facilitators can use to ensure all team members—no matter their comfort level, communication style, or background—have meaningful ways to show up, contribute, and engage.
