In May 2023, educational technology company Chegg faced a challenge that few leaders anticipated.
For years, the company had built a successful business around helping students access answers, tutoring, and learning support. Its leaders possessed deep expertise in education, technology, and customer behavior. Then generative AI entered the mainstream. Within months, students began turning to ChatGPT and similar tools for many of the same needs. Chegg’s stock dropped sharply as executives acknowledged that AI was fundamentally changing how students sought help.
Stories like this reveal an uncomfortable truth about leadership.
The problem was not a lack of expertise. The problem was that the assumptions underlying that expertise changed faster than anyone expected.
In my work studying organizational disruption, I have focused on what I call Rogue Waves — sudden, high-impact shifts that reshape industries, markets, and organizations with little warning. These disruptions are rarely the result of poor leadership. More often, they occur because successful leaders are operating with mental models built for a world that no longer exists.
The challenge is not whether expertise matters. It does. The challenge is knowing when expertise is helping us — and when it is quietly preventing us from seeing what has changed
When Expertise Becomes a Blind Spot
Most leaders are rewarded for expertise. Experience allows us to recognize patterns, make faster decisions, and navigate complexity with confidence.
Over time, however, expertise can create what psychologists call cognitive entrenchment.
Research by Erik Dane suggests that deep expertise can reduce cognitive flexibility. As our knowledge grows, we become more efficient at interpreting information through the lens of what we already know. The downside is that we grow less likely to question the assumptions behind our interpretations.
In stable environments, this efficiency is an advantage. In rapidly changing environments, it becomes a liability.
The world shifts, but the mental model stays the same.
This is not stubbornness. It is a natural consequence of how expertise is built — and why the very experience that helped us succeed can make it harder to recognize when the rules have changed.
Why Success Creates Overconfidence
Cognitive entrenchment often leads to a second challenge: overconfidence.
Confidence is generally viewed as a leadership strength. Teams want leaders who can make decisions under pressure and communicate a clear direction. But success naturally reinforces certainty. When a decision works repeatedly, we trust our judgment more deeply. Over time, that confidence can quietly harden into an assumption that our understanding of a situation is complete.
Research by David Dunning and Justin Kruger demonstrated that people are often far less aware of the limits of their knowledge than they believe. More recent leadership studies consistently find that overconfidence contributes to decision-making errors, particularly in uncertain and rapidly evolving environments.
Confidence itself is not the enemy. Many breakthroughs require leaders willing to act decisively in the face of ambiguity. The problem is confidence without calibration — when leaders stop asking what they might be missing.
The greatest risk during periods of rapid change is not uncertainty. It is certainty built on outdated assumptions.
The Leadership Skill We Actually Need
If expertise can become entrenchment and confidence can become overconfidence, what helps leaders remain adaptable?
Increasingly, researchers point to intellectual humility.
A growing body of psychological research defines intellectual humility as the ability to recognize the limits of one’s knowledge while remaining genuinely open to new information and alternative perspectives. The concept is often misunderstood. Intellectual humility is not self-doubt. It is not a lack of conviction or an inability to decide. It is the willingness to acknowledge that even our strongest conclusions may need revision when circumstances change.
Leadership Essential Reads
Expertise, in other words, is a resource — not a verdict.
The most adaptive leaders I know are not those with the most answers. They are the ones who continue asking questions long after they have become experts. They regularly challenge their own assumptions, actively seek out disconfirming evidence, and create space for the people around them to disagree.
Why Organizations Are Vulnerable Too
Individual leaders are not the only ones susceptible to these blind spots. Organizations are as well.
That realization led me to develop what I call the Octopus Organization, a business framework designed to make companies more distributed, intelligent, and adaptable to rapid change. Unlike traditional hierarchies that concentrate intelligence at the top, octopus organizations distribute it throughout the system. Information flows continuously from customers, frontline employees, partners, and emerging markets back into the core decision-making process.
When leadership teams rely exclusively on their own expertise, outdated assumptions can spread unchallenged through an entire organization. When information is distributed and assumptions are tested continuously, organizations become far more adaptive to disruption.
The goal is not to eliminate expertise. The goal is to build systems where expertise is constantly updated by reality.
The organizations that navigate disruption most effectively are rarely those with the smartest leaders. They are the ones that learn the fastest.
Expertise Is Not Enough
The central leadership challenge of our time is not acquiring expertise. It is knowing when to question it.
The pace of change continues to accelerate. Technologies evolve rapidly. Customer expectations shift without warning. Entire industries can be transformed in months rather than decades.
Cognitive entrenchment reminds us that expertise can become a blind spot. Overconfidence shows how success can produce false certainty. Intellectual humility offers a path forward.
The leaders who thrive in the years ahead will not be those who hold most tightly to what they know. They will be those who remain willing to learn — because surviving rogue waves requires more than experience. It requires the ability to recognize when yesterday’s expertise is no longer enough for tomorrow’s challenges.
