I once knew two young founders who were building a company together. From the outside, they were the perfect partners. They were always polite, always in agreement. They never argued.
Six months later, their company was dead.
Around the same time, I was mentoring another pair of founders. They fought constantly. Their board meetings were tense. They would debate product features with a passion that bordered on anger. I was worried their partnership would implode.
Today, their company is worth a fortune.
It took me years to understand the difference. I used to think all conflict was a sign of trouble. I thought harmony was the goal. I had it all wrong. The silence between the first pair wasn't harmony; it was the slow creep of death. The noise from the second pair wasn't chaos; it was the sound of something being forged.
Here is the simple, hard truth I learned:
Healthy conflict is a debate about what is right. Unhealthy conflict is a fight over who is right.
When the argument is about what is right, the focus is external. It’s on the mission, the customer, the product, the truth. It’s two people on the same side of the table, looking at a problem on the other side and attacking it from different angles. It’s like two blacksmiths hammering on the same piece of steel. The process is loud and violent, but the steel gets stronger with every blow.
This kind of conflict sharpens ideas. It stress-tests assumptions. It leaves no stone unturned. The goal isn't to win the argument; the goal is to find the best answer, together.
But when the conflict shifts to who is right, the focus turns inward. It’s no longer about the problem; it’s about ego. It’s about territory. It’s about personal validation. It becomes a tug-of-war, where every inch you gain is an inch your partner loses.
This kind of conflict doesn't build up; it tears down. It creates resentment. It erodes trust. It makes people afraid to bring up their best ideas for fear of being shot down. In a tug-of-war, even when one person "wins," the rope gets weaker. And eventually, it snaps.
Everything hinges on that distinction. But how do you know which one you’re in when emotions are running high? The signs are always there if you know where to look.
Ask yourself these questions in the heat of a disagreement:
What language are we using?
When the conflict is healthy, the language is about the problem. “I don’t think this strategy will work because of X.” “What if the product did Y instead?” The focus is on the thing you are building together.
When it’s unhealthy, the language becomes personal. “You always want to do this.” “My idea is better than your idea.” The pronouns shift from "it" to "I" and "you." That's the first and clearest danger signal.
How does it feel afterward?
Healthy conflict is exhausting, but it’s also energizing. You may feel drained from the debate, but you also feel a sense of progress. You feel closer to the truth, and often, closer to your partner because you’ve stress-tested the relationship and it held.
Unhealthy conflict just leaves you drained. There’s no progress, only resentment. It feels like you’ve lost ground, not gained it. You walk away feeling more distant from your partner, not more aligned.
What is the goal of the conversation?
In a healthy debate, the unspoken goal is to kill the bad idea so the best idea can live. You are both willing to be proven wrong. You are searching for the truth.
In an unhealthy fight, the goal is simply to win. The goal is to have your idea chosen, to be validated. You are defending a position, not searching for the truth.
So what do you do when you realize you're in a tug-of-war? How do you shift back to the anvil?
It starts with a simple, physical act. The next time you feel a disagreement becoming a personal fight, stop talking and change your position. Literally get up and move so you are standing or sitting next to your partner, looking at the problem together on a whiteboard or a piece of paper.
This small change in geography creates a massive change in psychology. It physically transforms the dynamic from a face-to-face confrontation into a side-by-side collaboration.
You cannot pull a rope when you are standing on the same side. You can only look at the problem in front of you.
Stop pulling. Start hammering on the steel. Together.
