Culture Is What You Tolerate

I have visited organizations with beautiful values statements framed on their lobby walls. Words like "integrity," "respect," "innovation," and "excellence" displayed in elegant typography. And I have watched those same organizations tolerate behavior that contradicts every one of those words. The values on the wall are aspirational. The culture is operational. And when the two diverge, it is the operational culture—what actually happens every day—that determines organizational performance.

The Tolerance Test

If you want to understand an organization’s real culture, do not read its mission statement. Watch what happens when someone violates its stated values. Does the organization address it, or does it look away? Does the senior leader who delivers results but treats people poorly get held accountable, or do they get a pass because they are too valuable to confront?

In New-School Leadership, I describe this as the tolerance test. Culture is not what you say. It is what you tolerate. Every time leadership lets a values violation pass without consequence, it sends a message to the entire organization: these values are optional. And once values become optional, they become decorative.

The High Performer Problem

The most corrosive cultural threat in most organizations is the high performer who violates cultural norms. They hit their numbers, they deliver results, they may even be brilliant at their work. But they are toxic to the people around them—dismissive, manipulative, territorial, or simply unkind.

When leadership tolerates this person because of their results, it communicates something unmistakable: results matter more than behavior. That single tolerance decision does more to define the culture than a hundred town halls about values. Every other employee watches and draws the obvious conclusion: the values are negotiable if you are productive enough.

The organizations with the strongest cultures are the ones willing to have the hard conversation with the high performer—and, if necessary, to let them go. That decision, more than any cultural initiative, proves that the values are real.

Small Tolerances, Big Consequences

Culture erosion rarely happens through dramatic events. It happens through small, daily tolerances that accumulate over time. The meeting that starts ten minutes late because the leader does not prioritize punctuality. The email that goes unanswered because responsiveness is valued in theory but not in practice. The idea that gets dismissed because it came from the wrong person or the wrong department.

Each of these small moments is a cultural signal. Individually, they seem insignificant. Collectively, they create an environment where people learn the real rules—the unwritten ones that actually govern behavior. If you want to change culture, start by identifying the small tolerances that contradict your stated values and eliminating them one by one.

Building Intolerance for the Right Things

Strong cultures are not uniformly tolerant or uniformly strict. They are precisely intolerant of the things that undermine their core values and broadly tolerant of everything else. A culture that values innovation should tolerate failure (which is inherent in experimentation) but be intolerant of blame (which kills experimentation). A culture that values respect should tolerate disagreement (which is healthy) but be intolerant of personal attacks (which are destructive).

The leadership challenge is making these distinctions explicit and enforcing them consistently. Consistency is the key word. Intermittent enforcement is worse than no enforcement, because it creates confusion about which behaviors are actually required and which are merely suggested.

The Leader’s Mirror

Before looking outward, every leader should look inward. What do you personally tolerate that contradicts your stated values? Where do you make exceptions for convenience, conflict avoidance, or political considerations? The culture of your team is a reflection of your tolerances, and changing it starts with changing what you are willing to accept.

This is uncomfortable work. It means having conversations you have been avoiding, making decisions you have been deferring, and holding yourself to the same standard you expect from others. But it is the only path to a culture that is real rather than aspirational.
