Game Theory and The Evolution of Trust

Why Trust Takes So Long to Build—and How to Get It Right

Every deal you've closed, every team you've held together, every partner who stuck with you through a rough quarter—all of it ran on trust. As a founder or executive, it's arguably the highest-leverage asset you have. And it's the one you can't buy, fake, or rush.

So how does trust actually get built? What enables its formation between two people—or prevents it?

A fascinating  game-theory simulation by Nicky Case offers one of the clearest answers I've seen. It models how cooperation evolves between self-interested players over repeated encounters—and watching trust emerge (or collapse) from a few simple rules is genuinely illuminating.

Set aside 30 minutes and play it yourself. Put it on your calendar like any meeting that matters. I promise it's worth the time. But if you want the short version first, here it is.

What makes trust possible

The simulation points to three conditions that have to be in place before trust can take root:

A shared future. Trust only develops when both sides expect to deal with each other again. The shadow of the next interaction is what makes cooperation rational today—it's why a one-off transaction feels riskier than an ongoing relationship, and why it should.

Room for a win-win. Trust requires a non-zero-sum game: one where both players can genuinely come out ahead. When the only way to win is at the other's expense, cooperation never gets off the ground—and no amount of goodwill changes that math.

Clear signals. A little miscommunication is survivable. Too much, and trust falls apart no matter how good everyone's intentions are. The noise itself becomes the problem.

When there is miscommunication, and uncertainty or doubt creeps in, it's better in the long run to tend toward giving the benefit of the doubt and away from assuming malice.

What this means for how you lead

Three things stuck with me after playing it through.

Don't expect trust on a startup timeline. You move fast and you want trust to keep up. It won't. Trust compounds through repeated, good-faith interactions—which means the only way to build it is to keep showing up and delivering, again and again, before you've seen the payoff. There's no growth hack here. The effort is the strategy.

Treat win-win as a discipline, not a disposition. Anyone can say they want everyone to win. Under pressure—a tight raise, a contentious negotiation, a co-founder disagreement—most people quietly default to zero-sum. The leaders who build lasting relationships do the harder thing: they get genuinely good at collaborative problem-solving and conflict resolution, and they deliberately surround themselves with and develop others who play the same way.

Over-communicate, then forgive. This is the one most leaders underrate. The strongest relationships are built on communicating clearly, accurately, and often—pausing to confirm understanding before acting on assumptions, rather than after. And when signals do get crossed (they will), the simulation is unambiguous: the players who extend the benefit of the doubt, rather than assume malice, win over the long run. In a high-stakes, high-speed environment, that generosity is a competitive advantage, not a weakness.

That last point is worth sitting with. The instinct under pressure is to read silence as a slight and a mistake as a betrayal. The math says do the opposite.

If this resonates, here are two ways I help teams put this into practice:

Solve the Right Problems, Faster

If you lead—or work with—a team in a growing startup or small business, you already know how quickly misalignment, rework, and stalled decisions can slow progress.

Leadership and the Middle Path is our foundational workshop designed to build the collaborative problem-solving skills your team needs to move faster, align better, and stay focused on what matters most.

Battle-tested in over 150 startups and Fortune 100 companies, this highly practical course helps teams:

• Reduce friction and costly missteps.

• Solve the right problems once—rather than repeatedly.

• Strengthen trust, clarity, and accountability.

Created by world-class OD expert Chris Holmberg, Leadership and the Middle Path is the cornerstone of our leadership development curriculum—and a game-changer for teams ready to level up.

Join us for the next series.

Hire with Confidence. Develop with Insight.

A misaligned executive hire can cost up to three times that leader’s salary—not counting the damage to culture, momentum, and trust. Hogan assessments bring evidence-based insight to these high-stakes decisions, showing how leaders are likely to perform, collaborate, and respond under pressure.

As a certified Hogan coach, I partner with founders, boards, executive teams, and search firms to hire with confidence and avoid costly missteps.

But hiring is only part of the story. I also use Hogan assessments with executive teams, founders, and senior leaders to accelerate their professional growth and create leadership development plans that are clear, specific, and useful. These same insights that help you select the right leaders can be turned into targeted strategies that help current leaders scale and thrive.

If you want more effective hiring decisions—and stronger leaders—let’s talk.
