Doubt is not leadership’s enemy but a practical response to uncertainty. Jenny Williams argues that leaders build trust by naming what they do not know, holding opinions lightly and inviting challenge. In complex environments, active doubt keeps thinking flexible, supports learning and helps organisations adapt, decide and move forward together.
Leadership can feel like a relentless roller-coaster ride: rapid turns, unexpected drops and little visibility of what lies ahead. The only certainty is uncertainty. And that uncertainty requires a reboot of the leadership playbook. The qualities of vision, clarity and decisiveness are not redundant, but they need to be partnered with other leadership qualities and skills.
I make the case for doubt: the uncomfortable bedfellow we are taught to ignore
Through my work with leaders and in my book Brilliant Doubt I make the case for doubt. Yes, doubt: the uncomfortable bedfellow we are taught to ignore, push through and certainly not associate with leadership. We are arguably over-familiar with its little sibling, imposter syndrome; something to overcome and leave behind. And yet, for many leaders, it follows them as they progress.
But what if doubt is the active partner of uncertainty and can help bring clarity?
Why doubt has a poor reputation
Doubt has long had a poor reputation in leadership. It is often seen as something to suppress or push through. Leaders are expected to appear confident and certain, particularly in public settings. Many of us have been taught that doubt signals weakness, hesitation or lack of capability.
But the reality is that doubt is not the opposite of leadership. In many situations it is an essential part of it. As leaders take on greater responsibility, they often become more aware of the complexity of the decisions they face. Information is incomplete, circumstances shift quickly, and the consequences of decisions are difficult to predict.
Why doubt matters in uncertainty
In these conditions, the expectation that leaders should always have the right answer becomes unrealistic. What leaders need instead is the ability to engage with uncertainty thoughtfully and constructively.
When uncertainty is high, projecting certainty can begin to ring hollow. Imagine the leader who stands in their monthly town hall assuring the organisation that the plan is the right plan, only for that plan to be revised again four weeks later. Over time, repeated certainty can begin to undermine trust rather than strengthen it.
Trust is built not from pretending we know everything, but from an honest assessment of the situation and from staying in conversation while working out the way forward. In 2026 we crave trust from our leaders. We also crave safe spaces to express our thinking. This is where doubt becomes useful.
Doubt allows thinking to remain flexible. It creates space for curiosity, challenge and adaptation. Without doubt, thinking becomes rigid and fixed. With it, leaders can adjust their understanding as new information emerges.
Professional doubt
In other words, leaders need a broader relationship with doubt, one that goes beyond the self. I call this Professional Doubt: doubt that operates across three layers:
- The self
- The situation
- The wider system
When leaders recognise these layers, doubt stops being something to avoid and becomes something to work with. It brings a maturity across the wider system.
Active doubt in practice
This is where Active Doubt comes in. Active Doubt is doubt with purpose. It is the process of actively engaging with doubt to see how it can help the situation. I think of it as doubt with its sleeves rolled up, ready to work. Rather than avoiding uncertainty or pretending it does not exist, leaders engage with it directly. They recognise that doubt is not a signal to stop, but a signal to think more carefully, ask better questions and remain open to change.
Active Doubt allows leaders to move forward while still acknowledging uncertainty.
In practice, this shows up in several ways.
- First, leaders name uncertainty openly. Instead of presenting decisions as fixed and final, they are transparent about what is known, what is still evolving and what may need to change. This honesty builds credibility rather than undermining it.
- Second, leaders hold their own opinions lightly. Decisions are treated less as permanent conclusions and more as working hypotheses. As new information emerges, leaders adjust their thinking rather than defending outdated assumptions.
- Third, leaders invite the opinions of others. They create a safe space for healthy challenge and curiosity. They encourage people in their teams to ask questions, raise concerns and test ideas. When doubt is welcomed rather than suppressed, it becomes a source of collective intelligence.
In uncertain environments, organisations that learn faster than the challenges they face are the ones that thrive. Active Doubt helps create the conditions for that learning.
Leadership in 2026 does not require less doubt. If anything, it requires more of it. But it requires a different relationship with doubt than many of us were taught. The leaders who will be most effective in the years ahead will not be those who eliminate doubt. They will be those who learn how to work with it to create change; change that benefits the organisation, its people and its customers.
In a world defined by uncertainty, doubt may be one of the most valuable leadership resources we have.
