The executive sitting across from me had just described, with some pride, the mental preparation routine he had developed over fifteen years. Before every high-stakes presentation, every difficult board meeting, every conversation he expected to be adversarial, he ran through a sequence of techniques he had accumulated from executive coaches, sports psychologists, and leadership development programmes. Breathing exercises. Visualisation. Internal affirmations about his capability and preparation. The whole sequence took about twenty minutes and, he said, it worked.
I asked him what he meant by worked.
He said he felt more confident going in. More ready. More in control.
I asked whether his performance in those high-stakes situations was consistently better than in lower-stakes ones.
He paused for a long time. Then he said, honestly, that he was not sure. That sometimes the high-stakes situations went well and sometimes they did not, and he had never been entirely certain whether the preparation was the reason or whether it was something else.
This is a more honest answer than most executives give. And it points to something important about the relationship between pressure and performance that the conventional mental toughness narrative gets substantially wrong.
The dominant model of performance under pressure in leadership development is essentially a control model. The premise is that pressure degrades performance because it generates internal states — anxiety, self-doubt, distraction — that interfere with execution. The solution, therefore, is to develop techniques for controlling those internal states: suppressing the anxiety, replacing the self-doubt with confidence, redirecting the distraction back to the task.
This model is not wrong. It is incomplete in ways that matter.
The research on elite performance — and here I mean genuinely elite, the top fraction of a percent in domains where performance under pressure is the primary variable — consistently finds something that the control model does not predict. The performers who are most reliable under pressure are not the ones who have developed the most sophisticated techniques for managing their internal states. They are the ones who have largely stopped trying to manage their internal states and have instead developed a different relationship with pressure itself.
This is not a semantic distinction. It has concrete implications for how performance under pressure should be developed.
To understand why the control model is incomplete, it helps to understand what pressure actually does neurologically.
Pressure activates the sympathetic nervous system — the fight-or-flight response — which produces a cascade of physiological changes: increased heart rate, elevated cortisol, heightened sensory alertness, reduced activity in the prefrontal cortex. The prefrontal cortex is the seat of the deliberate, analytical thinking that most high-stakes professional situations require. Its reduced activity under acute stress is the mechanism by which pressure degrades performance.
The control model responds to this by trying to prevent or reverse the activation. Breathing exercises work partly by activating the parasympathetic nervous system, which counteracts the sympathetic response. Visualisation and affirmations work partly by engaging the prefrontal cortex in a structured task, which maintains its activity against the suppressive effect of stress hormones.
These techniques are not without value. But they have a ceiling. And the ceiling is lower than most people assume, because the techniques themselves require cognitive resources — specifically, prefrontal cortex resources — to execute. Under genuine high-stakes pressure, the resources available for technique execution are precisely the resources that pressure has reduced.
This is the paradox at the heart of the control model: the techniques designed to manage the effects of pressure require the cognitive capacity that pressure has compromised.
The performers who are most reliable under pressure have not found a way to eliminate the physiological response to pressure. They have changed what that response means to them.
The research on this comes from multiple directions. Alison Wood Brooks at Harvard Business School has studied the difference between reappraising anxiety as excitement versus attempting to suppress it. Her findings are consistent: telling yourself "I am excited" before a high-stakes performance produces better outcomes than telling yourself "I am calm." The physiological state is similar — elevated heart rate, heightened alertness — but the relationship to that state is different. Excitement is a state of readiness. Anxiety is a state of threat. The difference is not in the body. It is in the interpretation.
This connects to a broader finding in the performance literature: the executives and performers who are most reliable under pressure tend to experience pressure as information rather than interference. The elevated heart rate tells them something important is happening and that they need to be fully present. It does not tell them that they are in danger or that they might fail. The distinction sounds simple. It is not easy to develop. But it is learnable.
The research on elite performance under pressure points to a practice that looks very different from the mental preparation routines most executives have been taught.
It is not about controlling internal states before the event. It is about developing, through repeated exposure, a stable relationship with the internal states that pressure produces. Not suppressing them. Not replacing them. Becoming familiar with them to the point where they no longer carry threat.
This is why the most effective preparation for high-stakes performance is not visualisation or affirmation but repeated exposure to conditions that generate the same physiological response — at progressively higher intensities, in progressively higher-stakes contexts, with progressively less time to recover between exposures.
The executive who has given a hundred difficult presentations is not less anxious before the hundred-and-first than before the first. But their relationship to that anxiety is different. They know what it feels like. They know it does not prevent them from performing. They have evidence, accumulated over time, that the feeling of pressure and the capacity to perform under pressure can coexist.
This is what the mental toughness literature calls "pressure inoculation," and it is one of the few interventions with consistent empirical support for improving performance under genuine high-stakes conditions.
The Resilience Assessment measures nine dimensions of performance capacity. The dimension most directly relevant here is what the assessment calls mental toughness — but the assessment's definition of mental toughness is deliberately different from the popular one.
Mental toughness, in the assessment framework, is not the capacity to suppress internal states under pressure. It is the capacity to maintain effective functioning while experiencing those states. The distinction matters because the first definition leads to a development pathway that has a ceiling — the control model — while the second leads to a development pathway that does not.
The assessment is designed to distinguish between executives who have developed genuine pressure tolerance — who have accumulated enough high-stakes exposure that pressure no longer carries the threat it once did — and executives who have developed sophisticated suppression techniques that work in moderate-pressure situations but fail in genuinely high-stakes ones.
Most executives, when they see their results, recognise the distinction immediately. They know which category they are in. The assessment just gives them a framework for understanding why, and what to do about it.
The executive I described at the beginning of this piece had developed a sophisticated preparation routine. It was not useless. But it was addressing the wrong problem.
The question is not how to feel less anxious before a high-stakes situation. The question is how to develop a relationship with the anxiety that allows you to perform effectively while experiencing it. Those are different problems with different solutions.
The preparation routine that actually builds pressure tolerance is not twenty minutes of breathing and visualisation before the event. It is a sustained practice of seeking out high-stakes situations, performing in them, reflecting on the performance, and returning to do it again — until the physiological response to pressure becomes familiar enough that it stops carrying the meaning of threat and starts carrying the meaning of readiness.
This is slower than learning a breathing technique. It is also more durable. And it is the only approach that does not have a ceiling.
