Why Good Leaders Make Bad Decisions Under Pressure.
Introduction
Most leadership failures are not caused by incompetence. They are caused by strengths that have been pushed too far, in the wrong moment, without enough self-awareness to catch it in time.
The most disorienting thing about leadership failure is that it almost never looks the way people expect. It does not usually involve a bad leader doing predictably bad things. It involves a good leader, someone with a track record of real results, genuine capability, and earned credibility, doing something that in hindsight makes very little sense. And when people try to explain it afterward, they reach for words like stress, or ego, or losing perspective. What they are actually describing is something the research on leadership has a precise name for: derailment.
Derailment is not a sudden collapse. It is a slow drift. It happens when the behaviors that built a leader's success stop fitting the context they are now operating in, and the leader, often without realizing it, keeps reaching for what has always worked even as the situation demands something different. The result is a performance gap that grows quietly until it becomes impossible to ignore. And by the time it is visible to the organization, it has usually been visible to the team for quite some time.
Research from Hogan Assessments, which has studied leadership performance across decades and hundreds of thousands of leaders, found that between 40 and 50 percent of senior leaders fail to meet expectations within 18 months of promotion or appointment. That is not a marginal failure rate. That is a near-coin-flip probability that the person just given more responsibility, more resources, and more organizational trust will not perform at the level the role requires. Understanding why that happens is one of the most important and most neglected conversations in leadership development.
The counterintuitive finding at the center of the research
The instinct when a leader fails is to look for what was missing. What skill did they lack. What blind spot did they carry. What character flaw eventually caught up with them. The research on leadership derailment consistently challenges that framing. Studies show that derailment does not correlate with low intelligence or poor social skills. In fact, some research shows the opposite: the derailed group often tests higher in perceived charisma and cognitive ability than their peers.
The problem is not what derailed leaders lack. It is what they have in excess, and what they cannot stop doing even when the situation is asking them to.
Researchers David Dotlich and Peter Cairo, whose work on executive derailment has shaped the field for two decades, identified the primary driver of leadership failure as habitual tendencies that turn toxic under pressure. These are not random or unpredictable patterns. They are repeatable and recognizable. The achiever becomes compulsive. The detail-oriented leader becomes paralyzed by caution. The relationship builder avoids every difficult conversation until the avoidance itself becomes the problem. These are not new behaviors. They are old behaviors, ones that worked well enough for long enough to become deeply ingrained, now operating without the calibration that better conditions once provided.
Why strengths become liabilities
The mechanism behind this pattern is one of the more uncomfortable findings in organizational psychology. Research consistently shows that executives derail under intense pressure largely because their strengths become weaknesses. And the reverse is not true. Under pressure, weaknesses do not suddenly become strengths. The leader ends up in a situation where they are only showing the overextended version of what used to serve them.
The leader whose drive and high standards produced exceptional results in a stable environment becomes, under sustained pressure, someone whose team experiences as relentless and impossible to satisfy. The confidence that made them decisive in moments of clarity becomes, when the stakes are highest and the information most incomplete, a closed-mindedness that shuts down the input they most need. The charisma that built followership becomes the authority that silences honest feedback.
Research on derailment behavior patterns shows that under pressure, people revert to type, relying on their preferred ways of doing things rather than stepping outside their existing comfort zones. The brain under stress defaults to what is familiar. And what is familiar for most successful leaders is the behavior that got them to where they are. The problem is that the context has changed, the role has expanded, the demands are different, and the old behavior is no longer the right tool for the situation even though it still feels like it should be.
The patterns that appear most often
The Center for Creative Leadership, which has studied leadership derailment across industries for decades, identified several patterns that consistently surface regardless of sector, role, or organizational level. None of them are technical failures. They are relational, behavioral, and cumulative.
They include the breakdown of interpersonal relationships, described in the research variously as arrogance, aloofness, or an inability to build and maintain trust across levels. Failure to deliver results, not from lack of effort but from overpromising, micromanaging, or becoming overwhelmed by the complexity that comes with expanded scope. And an inability to adapt to a changed context, continuing to apply a narrow set of proven approaches even as the environment requires something broader.
What makes these patterns so difficult to catch is that they develop gradually and without clear warning signals. Weaknesses tolerated early in a career become serious liabilities at senior levels. In early roles, supervisors tend to focus on a person's strengths and overlook or downplay their more difficult tendencies, which teaches the rising leader that those tendencies are not a serious risk. Every promotion reinforces that message. By the time the behavior becomes genuinely destructive at a senior level, it has been operating quietly for years, steadily reinforced by the success that surrounded it.
The self-awareness gap that makes it worse
The most frustrating feature of leadership derailment is that the people experiencing it are usually the last to see it clearly. Leaders often cannot recognize these patterns in themselves because the behaviors feel familiar and have produced results in the past. It seems, from the inside, like business as usual. But context does not stay still. Organizations evolve, roles shift, and the demands of leadership at each new level are meaningfully different from the demands of the level before. When leaders do not evolve alongside those demands, what was once a strength quietly becomes a liability.
This is not a failure of intelligence. It is a failure of feedback. In most organizations, the higher a leader rises, the less honest feedback they receive. The people around them have the most to lose from delivering difficult information and the least structural protection when they do. The leader operates in an increasingly filtered environment, receiving a version of reality shaped by what others believe they want to hear, while the patterns that most need to change continue unchallenged.
Research on what protects against derailment consistently points to two factors above all others: the ability to learn from experience and the active seeking of honest feedback. Not the absence of difficult tendencies, almost every leader has them, but the self-awareness to recognize them under pressure and the organizational environment that makes it safe to name them before they become destructive.
What this means for how organizations develop leaders
The practical implication of the derailment research is a significant reframe for how most organizations think about leadership development. The dominant model focuses on building skills, adding capabilities, and developing the competencies the role requires. All of that matters. But it addresses only half of the equation.
The other half, the half the research identifies as the primary driver of failure at senior levels, is the development of self-awareness about how a leader's own patterns of strength and tendency show up under pressure, and the cultivation of the psychological flexibility to adapt those patterns when the context demands it. That is not a skills conversation. It is a deeper one, about identity, about the stories leaders tell themselves about why they do what they do, and about the conditions under which those stories stop serving them and the people they are responsible for leading.
The organizations that take that conversation seriously are the ones building leaders who do not just perform when conditions are favorable. They build leaders who can recognize the moment their strengths are about to become liabilities and make a different choice before the damage is done. That kind of leadership does not develop through experience alone. It develops through the combination of honest feedback, deliberate reflection, and the willingness to keep growing after success has already arrived.
If you want your organization to develop leaders who perform consistently under pressure and not just when things are going well, Juan Bendana builds keynotes around the psychology of leadership, confidence, and what it takes to lead effectively through disruption and uncertainty. His talks are built for leadership conferences, corporate events, and sales kick-offs where the goal is not inspiration for the room but lasting change in how leaders show up when it counts.
The leaders who derail are rarely the ones who lacked talent. They are the ones who stopped growing after they found something that worked.
