Embracing the 10%

For years, we have been taught to build high-performing teams by hiring the best talent we can find. We refine job descriptions. We sharpen interview processes. We look for experience, credentials, cultural fit, and potential. When we get it right, we celebrate. We believe we have assembled a team capable of excellence. And often, we have.

Even in the healthiest, most thoughtfully constructed organizations, something inevitable happens.

People fall short.

They miss a detail. A deadline slips. A conversation does not land the way it was intended. A client walks away frustrated. A decision does not produce the outcome that was expected.

These moments are part of the rhythm of human work. I have been thinking about this as what I call “Embracing the 10%.”

The idea is simple. Even the most capable, committed, high-performing individual will not meet expectations 100% of the time. Most people, even at their best, consistently deliver somewhere around 90%. That remaining 10% shows up in visible ways.

It becomes the moment we remember most. The moment we document most carefully. The moment we discuss in leadership meetings. The moment that begins to influence how we see someone. A person can spend months, even years, performing at a high level, building trust, delivering results, and strengthening relationships. One visible failure can carry a different kind of weight.

There is research that helps explain this pattern.

Psychologists have long documented what is known as the negativity bias, the tendency for negative events to have a stronger psychological impact than positive ones. In organizational settings, this means mistakes and failures often carry more influence in evaluation than consistent, strong performance. Research by Baumeister and colleagues found that negative experiences shape perception and behavior more powerfully than positive ones.

This dynamic places a unique responsibility on leadership.

How leaders respond in these moments shapes the environment people work in and the way they show up in their roles. When mistakes are met with heightened scrutiny or emotional weight, employees begin to shift their focus. Attention moves toward avoiding errors and protecting reputation. Over time, this can narrow how people approach their work. Creativity becomes more measured. Risk-taking, which is necessary for innovation, becomes less frequent. Communication becomes more cautious and calculated.

There is also strong evidence that the environment leaders create directly impacts how people respond to mistakes. Research on psychological safety by Amy Edmondson shows that when individuals feel safe to take interpersonal risks, they are more likely to speak up, share ideas, and engage in learning behaviors. In environments where mistakes carry heavy consequences, people are more likely to remain silent and limit their engagement.

Leadership plays a central role in shaping how these moments are experienced.

Embracing the 10% begins with recognizing that these moments are part of performance, not separate from it. Leaders still hold standards. They still address what happened. They still expect accountability. They also place the moment within the broader context of the person’s contributions and growth. Conversations focus on understanding what occurred and identifying what can be learned. Feedback is given in a way that supports development. Attention remains on the work while maintaining respect for the individual.

This approach requires intention.

The 10% often carries real consequences. A project may fall short. A client relationship may need repair. A team may need to adjust quickly. Leaders feel the pressure connected to these outcomes. At the same time, leadership includes the ability to remain steady in how people are treated during these moments. The goal is to ensure that a single experience does not become the defining lens through which a person is viewed.

There is growing evidence that this approach supports long-term performance. Studies on learning-oriented leadership and error management show that teams perform more effectively when mistakes are treated as opportunities for learning. Individuals are more likely to adapt, improve, and remain engaged when they can process what happened and move forward with clarity.

When this environment is present, people stay connected to their work. They remain open about challenges. They recover more quickly. They continue contributing at a high level over time. This does not change expectations. It strengthens the conditions that allow people to meet them.

Sustained performance depends on resilience, adaptability, and the ability to learn from experience. These qualities develop in environments where people are supported as they navigate both success and difficulty.

Embracing the 10% is about recognizing the full range of human performance and leading in a way that allows people to continue growing within it. Because in the end, people will have moments where things do not go as planned. Leadership determines what happens next.
