In a recent LinkedIn post, Liz Bradford challenges conventional wisdom on building confidence, arguing that it is fundamentally a biological response rather than a purely psychological one. Bradford, who works with high-achieving executives, observes a common pattern: individuals who excel in many areas can falter in high-stakes situations, such as board meetings or public announcements.
According to Bradford, these moments of faltering are not indicative of a flawed mindset but rather a physiological reaction. She explains the underlying biological mechanism:
“Amygdala hijacks prefrontal cortex. Cortisol floods the system. Heart rate spikes. Breath goes shallow. Biology defaults to threat mode – not performance mode.”
Bradford asserts that traditional methods like confidence workshops, visualization, or even power poses often fail because they do not address this core biological reality. She contends that one cannot simply think their way out of a deeply ingrained physiological response triggered by perceived threats.
The Biology of Performance Under Pressure
Bradford points to executives who appear unflappable, suggesting they have not necessarily mastered their mindset but have inadvertently cultivated habits that regulate their biological stress responses. Drawing on the concept that “the body keeps the score,” a principle often discussed in trauma therapy, she emphasizes the body’s role in our reactions.
The Sequence to Reclaiming Control
The sequence Bradford outlines for regaining composure and effective performance is straightforward: a regulated body leads to a clearer mind, which in turn allows one’s voice to return, ultimately shifting the dynamic of the situation. As Bradford puts it:
“Safe body → clear mind → voice returns → room shifts. This is the sequence. Every time.”
This perspective shifts the focus from cognitive reframing to physiological regulation as the primary pathway to performing confidently under pressure. The implication is that by managing the body’s stress response, the mind can then function optimally.
Practical Strategies for Physiological Regulation
Bradford offers a surprisingly simple, evidence-based technique to counteract the physiological stress response before high-stakes events. Instead of relying on mental affirmations, she recommends a specific breathing exercise.
The Power of Breath
Bradford advocates for a 90-second breathing exercise with longer exhales – a 4-count inhale followed by a 6-count exhale. She clarifies the purpose behind this practice:
“Not because you’re ‘centering yourself.’ Because you’re changing your biochemistry.”
This technique is designed to activate the parasympathetic nervous system, which counteracts the fight-or-flight response and signals safety to the brain. By altering the body’s biochemistry, this practice aims to create the calm necessary for confidence to emerge.
Confidence Follows Calm
In conclusion, Liz Bradford’s insights on LinkedIn challenge the prevalent notion that confidence is solely a mental construct. She argues forcefully that addressing the biological underpinnings of stress and threat response is paramount. Her message to professionals is clear: confidence is not the starting point; it is the result of a regulated physiological state. As Bradford summarizes:
“Confidence follows calm. Never the other way around.”
This perspective offers a practical, biologically-informed approach for executives and professionals seeking to enhance their performance and presence in demanding situations.
