Most leaders would answer yes.

The better question is whether the people around them believe it.

Leadership requires making decisions in the absence of complete information. Every day, leaders form conclusions about customers, employees, competitors, market conditions, priorities, and risk. Those conclusions become assumptions, and assumptions become the foundation upon which decisions are made.

There is nothing inherently wrong with that process. It is impossible to lead without assumptions.

The challenge begins when assumptions stop being examined.

Over time, experience can create a subtle form of confidence that feels like certainty. What was once a hypothesis becomes accepted as fact. What was once tested becomes taken for granted. The questions that helped build success become less frequent because the answers appear obvious.

This is often where blind spots start forming.

Blind spots emerge because success itself can become evidence that our thinking is correct.

The danger is that yesterday’s evidence is not always evidence for today’s reality.

• Blockbuster was not short of resources.
• Kodak was not short of innovation.
• BlackBerry was not short of market share.

Each organization contained intelligent people, talented teams, and capable leadership. Yet assumptions about customers, technology, and the future became increasingly difficult to challenge.

The problem was not simply that they were wrong. The problem was that the assumptions remained largely untested while the environment continued to change around them.

This is why I am less interested in whether leaders say they welcome feedback and more interested in what actually happens when a deeply held belief is questioned.

• What happens when someone presents information that contradicts the current strategy?
• What happens when a junior employee sees a risk that senior leaders do not?
• What happens when data points in one direction while experience points in another?

Those moments reveal far more about a leadership culture than any mission statement ever could.

People pay close attention to these interactions. They learn whether questions are welcomed or tolerated. They learn whether disagreement is viewed as contribution or resistance. They learn whether the purpose of discussion is understanding or validation. Over time, those observations shape behaviour.

When people believe they can challenge an idea without damaging a relationship, threatening their reputation, or creating unnecessary friction, information flows more freely. Concerns surface earlier. Risks become visible sooner. Alternative possibilities receive consideration before decisions become commitments.

When people believe challenge carries a cost, something else happens.

The room becomes quieter. People may not be in agreement, but they collectively decide it’s not worth speaking.

One of the most important leadership capabilities may be the ability to move quickly from defensiveness to curiosity.

Feeling challenged is human.

Feeling uncomfortable is human.

Having your thinking questioned can create an immediate impulse to explain, defend, justify, or persuade. The real leadership work begins immediately after that moment.

• Can you become curious before becoming certain?
• Can you explore before concluding?
• Can you ask, “What am I not seeing?” before explaining why you are right?

Strong decisions are strengthened by challenge. The question is whether people believe it is worth challenging them.

That belief is rarely shaped by policy. It is shaped by experience. People learn very quickly whether questioning an assumption leads to thoughtful discussion, quiet dismissal, or personal consequences.
