BY THE OPTIMIST DAILY EDITORIAL TEAM Before your credentials or job title even enter the conversation, your brain and body are already working behind the scenes sending and interpreting signals of trust. These subtle cues, often unconscious, can make or break first impressions in the workplace. In an age of hybrid teams and digital communication, they matter more than ever. The good news? You don’t need to be a mind reader. You just need to be a little more mindful. According to Scott Hutcheson, PhD, a technology and engineering leadership expert and Senior Lecturer at Purdue University, trust isn’t a mystery. Hutcheson is the mind behind the Leadership Biodynamics Program, a behavior-based approach to executive presence. In short, it’s a series of small, intentional behaviors you can practice every day. Here are five science-backed ways to make others feel safer, seen, and more connected starting right now. 1. Give your full attention You know the difference between someone truly listening and someone just waiting for their turn to talk. So does your brain. Eye contact, leaning in slightly, nodding—all of these small behaviors signal active listening and help calm the other person’s nervous system. This reduces perceived social threats and builds psychological safety. According to research on neuroception (how our brains scan for signs of safety), showing you’re present and attentive makes others far more likely to see you as trustworthy. 2. Acknowledge what others bring to the table You don’t have to give a standing ovation every time a colleague speaks up. But small gestures like a sincere “thank you,” validating someone’s concern, or praising good work can go a long way. Acknowledgment triggers the release of oxytocin, the so-called bonding hormone, reinforcing trust and social connection. As Hutcheson explains, “Validation is a biological mechanism of social bonding.” 3. Be curious—not just charismatic It’s easy to default to your own experiences in a conversation. But when you keep the spotlight on the other person by asking thoughtful questions or letting them share more you amplify warmth. Behavioral research shows that people feel more positively about conversations when someone takes genuine interest in them. It’s one of the most underrated (and powerful) trust-builders. 4. Relax your vibe A friendly smile, a calm tone of voice, and an open posture might seem like soft skills but they have hard science behind them. These signals lower stress responses in others and encourage connection. Even subtle shifts can make a difference. A relaxed demeanor makes you more approachable and helps others self-regulate, especially in high-stakes situations. Humor, when used appropriately, can help too. 5. Let small actions speak loudly You don’t need grand gestures to build trust. Following up after a meeting, remembering someone’s birthday, or helping out before being asked can all send powerful signals of reliability and care. These consistent, thoughtful actions build what some call a “positive relational microclimate”. This is a kind of emotional weather system where trust, collaboration, and loyalty can thrive. Why warmth matters now more than ever In hybrid and remote workplaces, where hallway chats and coffee breaks are rare, intentional trust-building becomes essential. And science confirms: teams that build trust faster perform better, especially under pressure. As it turns out, trust isn’t about charisma or credentials. It’s about biology. And your biology already knows how to connect. You just have to let it.The post 5 subtle signals that make you more trustworthy at work (and beyond) first appeared on The Optimist Daily: Making Solutions the News.
