Don’t Overrely on Words: The Power of Nonverbal Cues in Communication
/
You’ve carefully structured your argument, chosen the right words, and presented your case. But instead of agreement, you’re met with hesitation. “Let’s revisit this later.” What went wrong?
Often, it’s not what we say—it’s how we say it. Research suggests over half of communication is nonverbal, yet many professionals, especially in STEM, rely almost entirely on words. The result? Misinterpretation, messages that don’t land as intended, and loss of influence.
Think about the last time someone told you, “I’m open to feedback,” but their arms were crossed, their foot tapped impatiently on the floor, and their tone was clipped. Did you believe them? Probably not. We sense misalignment instinctively, and when words don’t match body language, we trust the body more.
Or consider two engineers pitching the same idea. The first speaks clearly but stares at their laptop, arms crossed. The second maintains steady eye contact, gestures naturally, and modulates their voice for emphasis. Who’s more persuasive? The second—not because their idea is better, but because their delivery feels more confident and credible.
A key factor in aligning words and body language is self-awareness. If you’re anxious, your body knows before your brain catches up—your voice tightens, posture shrinks, or gestures become rigid. Instead of ignoring it, acknowledge it: “I’m feeling nervous, but I believe in this idea.” Simply naming your state can help regulate it, allowing you to adjust your tone, stance, or gestures intentionally.
Try this before an important conversation: Take a deep breath, plant your feet firmly, and exhale slowly. Roll your shoulders back, soften your gaze, and remind yourself of your intention: What do I want them to understand? This simple practice can help you shift from tension to presence.
Here’s how to ensure your nonverbal cues work for you, not against you:
Tune into yourself. Before speaking, ask: What am I feeling? How is it showing up in my body? Awareness is the first step to making adjustments.
Check your posture. Upright and open exudes confidence; slouching suggests uncertainty.
Be mindful of gestures. Hands jammed in pockets signal nervousness; purposeful gestures reinforce key points.
Use eye contact strategically. Not a stare-down, but enough to convey confidence and engagement.
Match your tone to your message. A hesitant voice undercuts a strong argument. A warm tone softens critical feedback.
Read the room. Others’ nonverbal reactions tell you when to clarify, pause, or shift approach.
In STEM, where complex ideas need clarity and trust, communication is more than words. It’s how you show up.
Have you ever seen great ideas fall flat due to poor delivery? What helped you or your colleagues improve?
