The 50/50 Rule: How to Turn Blame into Ownership
Stop asking “who messed up?” Start asking this instead.
“Who screwed up?”
I said it. You said it. Every leader has walked into a room after something went wrong and asked this question.
It feels like it promotes accountability. But it doesn’t.
We’re wired to look for someone to blame. We think that if we name a culprit, the problem will disappear. But blame is the easy way out. Instead of finding a real solution, we sacrifice someone for the greater good.
Here’s the thing: most failures aren’t caused by one person. They’re the cumulative results of mistakes made by many people. Blaming, or even firing someone, doesn’t fix the real problem. It just gives the illusion that we did.
But we didn’t. We just reset the clock.
The antidote to blame is shared ownership. This means when something goes wrong, everyone on the team shares responsibility, not just one person. That simple rule changes everything.
Change the Question. Change the Conversation.
Our brain naturally tries to protect us. Psychologists call this self-serving bias. When things go well, we credit our own skills and hard work. When things go wrong, we blame bad luck or other people.
In Forward Talk, I explain that blame is one of three conversational killers — along with avoidance and groupthink. All three hurt your team by keeping conversations stuck in the past. Who did what? Who dropped the ball? Who said what? The more your team focuses on finding fault, the less time people spend finding solutions.
Blame is cognitively cheap and emotionally satisfying in the moment. It seems like an effective defense mechanism. But it’s a decoy. It takes our attention away from the real problem and puts it on something less useful: figuring out who to blame.
I stumbled onto that realization about thirty years ago — not in a boardroom, but at home.
My wife and I were going through one of those arguments couples have over and over again. We were both sure that the other person was wrong. Then it struck me: by trying so hard to be right, we’d forgotten what we actually wanted — to fix a problem that was hurting our relationship.
So I proposed something that seemed absurd at the time. What if we both agreed we were equally responsible, no matter what actually happened?
Not because we were equally at fault. But because sharing the responsibility could change the conversation.
It worked. We’ve been married thirty years.
That’s what I call the 50/50 rule — the principle that changes the question from “who screwed up?” to “what was my part in this?”
I started using this principle with other relationships — friends, coworkers, and difficult bosses. Same result: when I stopped fighting to be right and started owning my part, everything changed. I stopped trying to win arguments and started solving problems. And making sure they didn’t resurface.
Eventually, I brought the 50/50 rule into my work with teams.
With two people, the split is intuitive. With a group, it works like this: the leader owns their half, the team owns theirs. And within the team, everyone must think about their part. The percentage doesn’t scale, but the principle stays the same. I want to invite you to try it with your team.
Change the question, and you change the conversation. Ask questions about the problem, not who to blame.
How to Use the 50/50 Rule with Your Team
When something goes wrong, everyone shares some responsibility — no matter what happened. Not equal percentages. The point isn’t to split accountability exactly in half. It’s to make sure no one’s share is zero.
Yes, sometimes one person really is mostly responsible. That happens. But in my experience with teams, it’s much rarer than you think — and thinking that way is often the self-serving bias talking. When in doubt, apply the rule first.
This works because it flips the script. When no one is the villain, no one needs to be the hero. Instead of fighting each other, we work together to solve a common problem.
Research from Stanford and the University of Michigan shows that organizations that attribute setbacks to factors within their control significantly outperform those that blame external factors. The 50/50 builds this mindset into your team.
The real power isn’t in the rule itself. It’s in how it changes five key dynamics that decide whether your team learns from mistakes or keeps making them.
Here are the key shifts:
From being right to understanding each other.
Most teams treat conflict like a debate they need to win. Nobody wants to be wrong, so people refuse to listen. When everyone shares responsibility, the conversation shifts from pushing our views to understanding the problem.
From taking sides to working together.
When a leader picks one side, someone wins and someone loses. And the bad feelings usually last longer than the decision. The 50/50 rule removes sides completely. There’s no side to pick, just a shared problem to solve together.
From defending yourself to being curious.
Blame turns colleagues into enemies. And enemies don’t ask good questions; they attack. Ownership brings people together. When there’s no right or wrong to defend, we become more curious about what others need and how they see things.
From pointing fingers to solving problems.
Blame is effortless. Owning your part requires courage. When everyone admits their part in the problem, the energy that went into self-defense is redirected toward resolution. Accountability comes from outside — it drives compliance and adds pressure. Ownership comes from the inside – it makes people want to solve the problem and increases commitment.
From winning to making good decisions.
Teams that focus on winning arguments do worse than teams that focus on better decisions. The 50/50 rule keeps everyone focused on what matters: what’s better for the team, not who gets to be right. Instead of fighting to win, the team asks: What do we need to decide right now to move forward?
Five Tips for Implementation
Building a culture of ownership starts with everyone owning their part — in failures, yes, but also in successes.
Knowing the 50/50 rule is one thing. Using it when tensions are high is another. Here’s how to make it work:
1. Go first:
Before the next difficult conversation, ask yourself: what did I contribute to this, even unintentionally? Ownership is contagious — but only if leaders start it. And you don’t need a title to go first.
2. Make it a team agreement:
The 50/50 rule only works when everyone plays by it. Introduce it explicitly, not as a one-off intervention but as a shared operating principle: when things go wrong, we all own part of it. That one agreement changes every hard conversation after that.
3. Run blameless postmortems:
Replace “what went wrong?” with “how did each of us contribute to this?” That one question turns a blame session into a learning conversation — and surfaces solutions that finger-pointing never would.
4. Separate the person from the problem:
Blame is personal. The 50/50 rule makes problems shared. When the conversation shifts from “you did this” to “we created this together,” you can focus on the decision, the communication, or the process that broke down — not the person across from you.
5. Call a time-out when needed:
The rule is hard to apply mid-conflict. Give your team permission to pause if things get too tense. Facilitating blameless conversations is not easy. Cooling down doesn’t help everyone think more clearly, but it stops things from running out of control.
This Principle Will Shape Your Culture
You can have a culture of ownership or a culture of blame. You can’t have both. The difference lies in the question your team asks.
When something goes wrong, do people immediately ask, “Who did this?” or do they step back and ask, “What was each of our parts in this?”
The 50/50 rule isn’t perfect. It’s an invitation to stop protecting ourselves and start solving problems so they don’t happen again. It’s a rule because it changes behavior. When things break down, you can’t stand on the sidelines and point fingers. You have to own your part.
