- 70% of change initiatives fail to deliver their intended results.
- Research shows that having a people-centric approach increases the chances of success by up to 12x.
- To do this, leaders need to have an understanding of the human brain and how it responds to change, uncertainty and the unknown.
This is the first in a series of eight articles where I’ll teach you my ‘REWIRE Model’of leading organisational change. Eight neuroscientific principles that will help you create lasting positive change in your team or organisation.
PRINCIPLE 1: THREAT & UNCERTAINTY RESPONSE
Resistance to change is a natural response to threat and uncertainty, status risk, and loss of control. Your task as a leader is to make things predictable, and maintain people’s status and autonomy as much as possible.
THE NEUROSCIENCE
Your brain is a prediction machine. Change is interpreted by the brain as potential threat: it signals uncertainty, reduced control, and possible social risk. The amygdala and other salience networks scan for danger, and when threat is detected the stress response is activated.
In a state of threat, stress hormones and sympathetic arousal narrow attention and bias thinking toward short-term safety. Executive functions associated with the prefrontal cortex – planning, decision-making, problem-solving, emotional regulation and learning – become less reliable, and working memory capacity shrinks.
So at the very moment you need people to think clearly, effectively and adapt – their brains are biologically less able to do so.
Social threats matter as much as operational ones. We are profoundly social creature so risks to status (expertise, contribution), fairness or belonging also trigger defensive responses.
Uncertainty amplifies all these effects. When people cannot predict what will happen, the brain fills gaps with worst-case scenarios, increasing rumination and resistance. This sensitivity to uncertainty is why even positive change (a new system, or restructuring for growth) can provoke anxiety and resistance.
Just as uncertainty amplify the stress response, perceived control (sense of agency) dampens threat detection. Sense of control fundamentally changes how the brain processes stress, so it is lower and shorter-lived.
THE BOTTOM LINE
Resistance isn’t about the quality of your strategy. It’s about the state of people’s brains.
WHAT TO DO
Do these things to reduce threat and enable adoption:
1) Clearly articulate WHAT is changing and WHY.
The brain’s threat response escalates when change feels arbitrary. Present clear evidence of why the status quo is unsustainable – financial realities, market data, competitive threats. Make the case that NOT changing is the bigger threat.
2) Be explicit about what is NOT changing.
Create islands of predictability by being explicit about what will remain stable. “Your team structure is changing, but your location, salary, and core responsibilities are not.” This gives the brain something certain to anchor to.
3) Be open and honest about what is known – and what remains UNDECIDED.
Communicate what you do know with precision. But demonstrate that leadership shares the uncertainty. When leaders pretend to have all the answers, it activates distrust and increases threat response. Say “I don’t know, but here’s how we’ll figure it out” rather than fabricating false certainty.
4) Acknowledge the threat explicitly and validate the emotional response.
Don’t dismiss or minimise people’s concerns. The brain needs acknowledgment that the threat it’s detecting is being taken seriously. This paradoxically reduces threat response because the brain feels “heard” and can begin processing rather than remaining in defensive mode.
5) Increase communication frequency by 10x what feels sufficient.
Repeat core messages through multiple channels, multiple times. People don’t properly encode or remember information delivered when they’re under threat. Consider creating a single source of truth, or FAQs accessible to everyone – so people know where to find the most current information.
6) Create predictable touchpoints and rhythms during the transition.
Even if the destination is unclear, predictable structures reduce uncertainty. Establish regular update meetings, consistent communication schedules, and reliable feedback loops. “We’ll meet every Tuesday at 10am to discuss progress” provides neural scaffolding.
7) Protect perceived status
Status threats activate the same neural circuitry as physical pain. Acknowledge expertise built under the old system, avoid language that implies people are “behind” or “obsolete”, and involve respected insiders as visible contributors to the change.
8) Give people agency and control wherever possible
Offer choices in timing, method, or implementation approach. The perception of control significantly reduces the psychological impact of loss, even when the ultimate outcome is the same.
9) Treat resistance as diagnostic data and respond with curiosity rather than defensiveness or coercion
When people resist, they’re providing valuable diagnostic information about unmet needs, unclear benefits, or genuine risks you may have missed. Ask “What specifically concerns you? What would need to be true for this to work for you?”
DIAGNOSTIC QUESTIONS
Answer the following questions and you’ll get a sense of how you’re doing with Principle 1: Threat & Uncertainty Response:
- Can people articulate what IS, and what is NOT changing?
- What uncertainties can we clarify, and are we communicating enough?
- Where are we unintentionally increasing uncertainty?
- Do managers have the language and time to hold emotions and questions?
- Where might this change threaten status, identity, belonging?
- What choices have we given teams about how the change is implemented?
RED FLAGS TO WATCH OUT FOR
Watch for these patterns – they signal you’ve got some work to do:
🚩 Communication is not landing, or the same questions are being asked repeatedly
Information delivered when the amygdala is activated simply doesn’t encode into memory effectively. Repetition alone won’t fix this; you need to reduce threat first.
🚩 Emotional reactivity and anxiety are visible (or conspicuously absent)
When people show heightened emotional reactions (frustration, anger, anxiety), their limbic systems are running the show.
🚩 Defensiveness and risk aversion escalate
When the amygdala is activated, the brain defaults to defensive, self-protective mode. You’ll notice people suddenly raising objections to things they’d normally accept, focusing on what could go wrong or worst-case scenarios.
🚩 Rigidity or over-attachment to existing systems
Under threat, the brain clings to what’s familiar because familiarity equals safety. You’ll hear language like “but we’ve always done it this way” or “the current system works fine.”
🚩 Withdrawal and disengagement become noticeable
When people stop asking questions, become quiet in meetings, or seem checked out, their brains may have moved from active threat response (fight) to passive threat response (flight or freeze).
🚩 Trust scores or engagement metrics are declining
When some people’s amygdalas activate, others observe the threat signals (body language, tone, behaviour) and their own threat systems activate in response. This is why resistance can seem to spread like wildfire – even among people not directly affected by the change.
