In people management, trust comes up all the time. But it’s usually treated as a soft, intangible concept—hard to define and even harder to manage. Science tells a different story. Trust isn’t just an emotion or a good intention: it’s a biological process. And when it’s activated, it changes everything.
Trust isn’t intuition: it’s chemistry
Thanks to the work of neuroeconomist Paul Zak, we now know that trust has a measurable foundation: oxytocin.
This neurotransmitter, released in moments of social connection, is directly linked to behaviors such as generosity, cooperation, and engagement.
So what happens when trust exists within a team?
People stop wasting energy protecting themselves and start using it to innovate, collaborate, and create value. Trust literally frees up mental bandwidth.
What breaks (and what sustains) trust
Harvard professor Frances Frei sums it up with three pillars: Authenticity, Empathy, and Logic. When one fails, trust starts to wobble.
-
Empathy: You can’t connect if you’re distracted. Checking your phone in the middle of a conversation or meeting shuts down oxytocin. Presence is the foundation of connection.
-
Authenticity: Leading behind a professional mask doesn’t create safety. People need to know they can be themselves without fear of consequences.
-
Logic: Even with good intentions, if decisions or ideas aren’t clearly explained, credibility is lost. Starting with the key message helps create understanding.
How to build a high-trust environment: the OXYTOCIN model
Paul Zak also identified eight practices that stimulate trust at work. Together, they form the acronym OXYTOCIN, and they can help you design more human and effective work experiences:
Ovation: recognize publicly and unexpectedly
Recognition activates oxytocin and strengthens bonds. When people feel seen and valued, not only does individual motivation increase—team cohesion improves as well.
That’s why it matters to celebrate wins, big or small, genuinely and in shared spaces. Gratitude costs nothing, but it has a direct impact on collective energy.
Expectation: set motivating challenges
People perform better when they feel their work matters. Setting ambitious but achievable goals, aligned with a shared purpose, activates engagement and voluntary effort.
It’s not about applying pressure—it’s about setting a direction that inspires the team to grow and excel together.
Yield control: give autonomy and trust
Intentional delegation is one of the strongest signals of trust. When teams have room to decide how to approach their work, creativity, accountability, and engagement flourish.
Micromanagement, by contrast, communicates distrust and limits people’s potential.
Transfer: allow roles to be redesigned
Giving people space to adapt their roles to their strengths, interests, and experience—what’s known as job crafting—boosts engagement and a sense of belonging.
This flexibility encourages self-management and turns work into a place where people can bring their best selves.
Openness: share key information
Trust erodes in uncertainty. When leadership shares goals, decisions, and major changes transparently, it creates a climate of safety and maturity.
Perfection isn’t expected, nor having all the answers—but honest, respectful communication is.
Caring: show genuine interest in people
Beyond goals and tasks, work is done by human beings. When leaders show real interest in how people are doing—not just what they deliver—it activates a sense of connection that sustains trust, even in tough moments.
Asking, listening, and supporting are simple acts that leave a lasting mark.
Investment: commit to professional growth
Engagement grows when people feel their development matters. Investing in training, learning, or new opportunities isn’t just generous—it’s a smart strategy for retaining talent and building the future.
Those who feel supported in their growth tend to give that commitment back through involvement and loyalty.
Naturalness: lead with authenticity
People don’t connect with perfect versions—they connect with real leaders. Showing vulnerability, acknowledging mistakes, or speaking honestly doesn’t reduce authority; it strengthens it.
Authenticity humanizes leadership, inspires others, and creates an environment where psychological safety is possible. And when that happens, teams dare to go further.
What does all this have to do with performance?
Everything.
In high-trust cultures, mistakes are acknowledged earlier, innovation emerges more often, and teams perform better without excessive control. Google confirmed this in its famous Project Aristotle: psychological safety was the most decisive factor in team success.
How to get started: measure, talk, redesign
The first step in building a culture of trust is to stop assuming—and start asking.
With Team Insights, you can measure perceptions of safety, support, and openness within your team and identify where trust is breaking down.
From there, you can take small, high-impact actions: give honest feedback, recognize an achievement, share a difficult decision transparently. Consistency is what matters.
In conclusion
High performance doesn’t start with processes—it starts with relationships. And trust is built from the inside out.
If you want your team to collaborate, innovate, and learn faster, all you need to do is activate what already exists in the human brain and start designing environments where trust is a daily practice.
