In my first blog in this series, I introduced you to the SCARF model — a brain-based framework by David Rock that explains why people react the way they do.
To recap, SCARF covers five elements our brains are constantly scanning for threats or rewards: Status, Certainty, Autonomy, Relatedness, and Fairness. Today we’re diving into the second element: Certainty.
Certainty: Why We Crave Clarity
The brain is a prediction machine. It wants to know what’s coming next so it can save energy. When things feel uncertain, the brain burns more resources to process what’s happening, and attention is pulled away from our goals.
Even small amounts of uncertainty set off an “error” response, like a flashing printer icon you can’t ignore until the paper jam is fixed. Larger uncertainties, like unclear expectations from a manager, or not knowing if your job is secure, are highly debilitating.
On the other hand, even a small dose of clarity feels rewarding. Meeting expectations creates a dopamine hit, which is why a familiar routine, clear instructions, or a predictable rhythm can feel so comforting.
My Recent Airbnb Anxiety
On our recent month-long trip to France, Andy and I coined a new phrase (for us, others may already have experienced it) Airbnb Anxiety.
Each new place we stayed in came with questions: Will it be as pictured and described? Will it be clean? Will it feel safe? Most of the time, the answer was yes and sometimes even better than expected. But two experiences triggered this sense of uncertainty and anxiety.
One place looked beautifully staged in the photos, the description amazing, even the reviews were high. In reality, it was dirty, smelly, on a busy road, and the “cleaning cloths” had mould growing on them, looking closer, seems like the reviews might have been staged or from ‘mates’. Another was pitched as a ‘country house’ with a pool, but turned out to be towered over by ramshackle flats, the pool pictures were at least 10 years old and the room so tiny, up narrow back stairs, it felt like we were being hidden away like naughty children.
That’s what uncertainty does. Until it’s resolved, your brain can’t relax — you’re stuck scanning for what might go wrong.
What Threat Looks Like
In the workplace, Certainty threats can look like:
- Unclear roles or shifting priorities.
- Leaders being vague about expectations. According to Gallup Only 44% of employees know what’s expected of them at work.
- Meetings that drag on without clear direction.
- Organisational change with no timeline for information.
The brain reads all of this as “error messages,” and attention shifts to the uncertainty instead of the task at hand. Productivity and morale plummet.
From Threat to Reward
The good news is that leaders and peers can create Certainty rewards in surprisingly simple ways:
- Set clear expectations upfront.
- Break complex projects into smaller, predictable steps.
- Be explicit: “This meeting will run for 30 minutes” or “You’ll have an update on Friday.”
- Repeat and summarise key messages (“Tell them what you’re going to tell them, tell them, then tell them what you told them”).
Gallup research shows that clarity is critical: employees who strongly agree that their manager helps set priorities and performance goals are nearly 4x more likely to be engaged at work.
Why Certainty Matters for Teams
Certainty is one of the fastest ways to unlock stronger teamwork.
When expectations are clear, people can use their strengths intentionally. An Analytical knows where to focus, a Maximizer can polish the right things, and an Activator can channel energy into action rather than spinning wheels.
Certainty helps build trust, because people know what to expect from each other and can rely on shared commitments.
It reduces the temptation to retreat into silos. When people know the bigger picture, they’re more willing to share across teams rather than protect only their patch.
Certainty improves communication by removing noise. Stating what success looks like, clarifying the “why,” or simply giving an end time for a meeting means everyone can relax and contribute more fully.
Questions to Create More Certainty
Leaders and coaches can ask:
- What would help make expectations clearer for you?
- How confident do you feel about what success looks like here?
- What’s one thing I can clarify that would help you focus right now?
These aren’t complicated but they reduce the flashing error signals and free up the brain to do its best work.
Certainty is about clarity and predictability. When it’s missing, our brains work overtime, fuelling anxiety and disengagement. When it’s present, people engage and perform better.

Reflection for You:
Where might a lack of certainty be holding back you or your team right now? What’s one small step you could take to make things clearer?
