Even at the highest level, decision-making rarely breaks down because of a lack of intelligence or experience. It breaks in the moments where friction appears — and is quietly moved past.
A data point doesn’t fit. A concern is raised. Something feels slightly off. The signal is there, but instead of slowing down to examine it, the nervous system resolves it. The tension disappears, the decision continues, and the sense of clarity returns.
That shift is not always conscious. It is the cortisol feedback loop — a pattern that reduces discomfort by moving attention away from contradiction. What feels like progress is often the result of friction being neutralised rather than understood.
While the dopamine loop, Dopamine-Driven Momentum, accelerates conviction when something fits, the cortisol loop operates in the opposite direction. It softens what doesn’t fit. It reduces the weight of contradiction. It allows decisions to continue without fully processing the signals that should challenge them.
This is one of the most consistent findings in our research. In our study of 100 CEOs and senior executives in the UK technology sector, 80% fell into the High range of cortisol-driven discomfort in decision-making — meaning that for four out of five leaders, contradiction was being neutralised rather than examined, and it felt like clarity while it happened.
How the Loop Works
The cortisol loop follows the same structure as the dopamine loop: trigger, response, and reinforcement. The difference is that this loop is built around avoidance rather than reward.
The trigger occurs when you encounter information that contradicts your initial belief about a project or decision. It might be data that doesn’t support your forecast, feedback that challenges your assumptions, or a signal that something is not working as expected. The information does not fit.
In response, your brain releases cortisol. This is not experienced as panic or obvious stress. It feels more like discomfort, disappointment, unease, resistance, or a subtle urge to move past the issue. There may also be a sense of rushing — a desire to resolve the tension quickly.
Avoidance follows. You downplay, reinterpret, or rationalise the information. “It’s too early.” “This doesn’t apply to us.” “We’ve handled bigger challenges.” The explanation sounds logical, but its function is to reduce discomfort.
Then reinforcement occurs. Once the uncomfortable signal is dismissed, cortisol drops and the nervous system stabilises. Attention shifts back to confirming evidence. Dopamine rises again. The decision feels aligned and correct. Relief strengthens the pattern.
Over time, the brain learns to avoid contradictory evidence because avoiding it reduces discomfort. Instead of treating friction as a signal to investigate, the nervous system learns to neutralise it quickly. The result is a decision process that feels confident and smooth — but is less precise than it appears.

The Blind Spots That Come With It
When avoidance becomes embedded, the decision process remains active — but its direction changes. You continue moving, but not necessarily with full visibility.
Instead of asking what might be missing, attention shifts toward what supports continuation. Contradictory signals are reinterpreted rather than examined. Risks feel manageable rather than urgent. Momentum is preserved, but accuracy is reduced.
Corrections still happen, but they happen later — under pressure, under cost, and under time constraints that were not originally necessary. The system protects the decision in the moment, but not the outcome over time.
Why This Matters for CEOs
At the executive level, the issue is not hesitation. It is the lack of awareness of how chemistry shapes what gets examined and what gets dismissed.
You are used to operating under pressure, making decisions with incomplete information, and maintaining momentum when others hesitate. But when the cortisol loop is active, the nervous system does not recognise friction as a signal to investigate. It resolves it instead.
This creates a subtle but critical shift. You are no longer deciding based on what is fully examined, but on what feels resolved. The decision remains coherent, but the process behind it is incomplete.
Awareness changes that dynamic. The moment you recognise discomfort as a signal — not something to remove, but something to examine — the decision process becomes more precise. Chemistry still operates, but it no longer determines what you choose to see. This is what leaders describe once the pattern becomes visible — not more hesitation, but sharper thinking:
“He introduced a structured decision-making framework that materially enhanced the quality of our thinking, reduced unhelpful assumptions, and brought greater precision to how we communicate… work that translates into sustained improvement in how people think and operate.”

See If This Loop Is Driving You
If you’d like to see how cortisol-driven discomfort shapes your decision-making — how often friction is reduced rather than examined — you can take the Neurochemically Optimised Executive Assessment. It reveals how dopamine and cortisol interact in your decision process, showing where momentum may be overriding scrutiny and where avoidance may be influencing what you choose to examine.
It isn’t a personality test. It measures the intensity of the internal signals — reward, avoidance, alertness — that shape your decisions before logic engages. It takes five minutes, it’s free, and it gives you the same baseline measurement used with the 100 CEOs in our study.

Tomasz Drybala is the founder of the Neuro-Based Leadership Centre and the architect of a neuroscience-based regulatory framework designed for CEOs, founders, and senior executives. His work focuses on measuring and regulating the neurochemical feedback loops that shape executive decision-making, daily execution, and recovery cycles — operating at the level where perception is formed, before logic engages. Alongside building his executive framework, he pursued targeted programs through institutions including Harvard, Cambridge, Oxford, and the University of California, Berkeley, and leads an applied research body that examines how feedback loops involving dopamine, cortisol, oxytocin, serotonin, and testosterone influence judgment, timing, and execution in real organisational environments.
