Many leaders talk about transformation. But behind closed doors, most will admit it often feels like trying to sprint through molasses — heavy, slow, and draining.
Deadlines blur, decisions pile up, and new initiatives fight for the same shrinking pool of energy and attention.
It’s easy to frame that as a motivation problem. Maybe people just need to “get on board.”
But what if the real issue is biological? What if change stalls because the brain can’t keep up with the pace of organizational ambition?
That question took centre stage at a Calgary event this fall hosted by Cortical Consulting & Coaching, which brought leaders and scientists together to explore how the brain shapes performance under pressure.
“Stress is not objective,” said neuroscientist Matthew Hill. “It’s an incredibly subjective experience. There is nothing in this world that, in and of itself, is inherently stressful.”
Hill is the research chair for the Mental Health Initiative for Stress and Trauma (MIST) at the Hotchkiss Brain Institute where he studies what stress actually does to the brain.
As Hill explained, when your brain is telling you a situation is stressful, a cascade of responses affects your hormones, psychology, and the very way you approach a situation. In other words, the brain decides what’s a threat, and the body follows.
In the workplace, that can present challenges. When organizations move too fast, pile on new priorities, or shift direction without helping people process what’s happening, they short-circuit any meaningful capacity.
Tammy Arseneau, founder of Cortical Consulting & Coaching and the driving force behind the summit, sees this pattern play out every day.
She designed the event around a question that drives much of her work. Why do so many change efforts fall short? Her answer is rarely about flawed plans or weak execution. It is that leaders underestimate the stress response change creates inside the system itself.
“What if the missing link in leadership isn’t another model or framework?” she asked. “What if it’s just about understanding ourselves better in those moments of stress… in those moments where it really matters and we need to step up. What if it’s in those moments where we’re leading our team and we have a better understanding of who they are and what motivates them, or what’s happening during high times of change and stress.”
It’s a question that shifts the focus from performance to physiology. Because the moment stress enters the system, it stops being a leadership problem and becomes a brain problem.
And not the fun sudoku kind.
When pressure turns into noise
The irony is that stress itself isn’t the enemy. As Hill points out, the right kind of pressure can sharpen performance.
“Good stress tends to fall into the category of things that might be challenging, but things that we are able to muster ourselves through,” he explains. “Bad stress… is almost always defined by unpredictability and uncontrollability.”
The moment the brain flips from focus to defence is the breaking point.
Once it decides it has no control, it shuts down higher reasoning and narrows attention. It’s not a personal flaw or lack of resilience. It’s just how our systems are wired.
Arseneau often talks about the importance of reading a room’s cognitive load, or gauging how much pressure people can realistically process before they stop hearing what’s being said.
After all, you can’t think strategically if your brain is still trying to find safety.
That’s why Cortical’s approach to organizational change isn’t about pushing harder. It’s about sequencing transformation at a pace the human brain can actually process.
“Organizations don’t fail because of change itself,” said Arseneau. “They fail when change exceeds our ability to adapt. Our job is to help leaders clarify and sequence ambition in a way that people can actually absorb.”
When the brain hits its limits
What we can draw from Hill’s “bad stress” explanation is that chronic stress doesn’t just make people tired, but it rewires the brain.
Neuroscience research shows that when the brain senses threat or uncertainty, it triggers a surge of stress hormones such as cortisol and adrenaline. In short bursts, they help us stay alert. But when pressure lasts too long, those same hormones can disrupt how the brain and body communicate, affecting focus, judgment, and recovery.
When leaders are under sustained stress, their perception narrows and reactions become more defensive. Arseneau sees that pattern frequently in her work with leaders navigating complex change. She says it shows up as “a kind of cognitive and physical overload” that leaders rarely notice until it starts affecting their teams.
That insight reframes communication entirely.
For Cortical, effective leadership begins with awareness, and knowing how stress shapes what people can hear, process, and trust.
Why empathy is a performance tool
Deborah Yedlin, president and CEO of the Calgary Chamber of Commerce, also shared her thoughts at the event and brought the conversation back to the human side of leadership.
She spoke about how mental health needs to be seen not as a private struggle, but as a shared responsibility within the business community.
When a respected surgeon she knew died by suicide, Yedlin could see the ripple effect across Calgary.
“The village hurts when we lose a person,” reflected Yedlin.
Yedlin reminded the audience that behind every title and achievement, people carry unseen strain. When leaders make space for honest connection, they help others feel less alone.
“We need to give the entrepreneurs the tools to support their employees,” she said. “We need to give the employees the comfort to say that they need the help that they seek in order to show up as their best self, whether that’s at home or in the workplace.”
Arseneau calls that “organizational empathy.” She describes it as the awareness that attention, focus, and energy are shared resources, not infinite ones.
It’s the ability to treat attention, focus, and energy as shared corporate resources instead of assuming everyone has an infinite supply.
Arseneau often says empathy is misunderstood in business. In her view, empathy allows organizations to absorb strain and adapt instead of breaking under pressure.
“What looks like disengagement is often just overload,” she said. “When leaders can read that signal early, they can adjust expectations and keep the work — and the people — moving forward.”
One of Yedlin’s initiatives is the Chamber’s Mental Mondays series, a three-year initiative between the Calgary Chamber of Commerce and Cenovus. The series aims to promote and encourage mental wellness among both leadership and employees, and serves as an example of how that empathy takes shape.
They’re the same kinds of conversations Arseneau encourages inside companies, which are candid, grounded, and focused on making the invisible work visible.
Change isn’t strategic until it’s biological
It’s easy to forget that change starts in the brain, not the boardroom.
Every new system, restructure, or innovation demands that the brain unlearn old patterns and form new ones. That takes time, energy, and safety.
So if the brain adapts in stages, not leaps, then leadership needs to be paced with that reality in mind.
That’s an additional lens that Cortical brings into their work in organizational change. By helping companies plan and execute transformation in a way that matches human capacity, the result isn’t just less burnout. It’s higher-quality decisions made by people who still have the bandwidth to think.
Arseneau coaches executives to understand how stress shifts perception and judgment, what she calls “learning your own dashboard.”
She says leadership starts with self-awareness, understanding what stress does to perception and decision-making. Awareness of those shifts is what allows leaders to respond with clarity instead of instinct.
Change succeeds when pace, purpose, and pressure are aligned with what people can realistically process. In a world where volatility has become the norm, that may be the most strategic skill a leader can have.
Final shots
- Leaders can’t out-strategize the brain. Real transformation happens when people have time and safety to adapt.
- The fastest way to derail change is to rush it. Sequencing transformation to match human capacity keeps teams thinking instead of reacting.
- Seeing attention and energy as shared resources helps organizations absorb strain instead of breaking under it.
- When leaders understand how stress shapes perception and decision-making, they can respond with focus instead of instinct.
