For more than 20 years, I have spoken about leadership, worked with leaders and spent time observing what happens inside organisations when people are asked to lead change, build teams and make difficult decisions.

One thing has consistently fascinated me.

Leaders are often very good at looking outward—and surprisingly uncomfortable looking inward.

They give feedback. They evaluate performance. They identify what others are doing wrong. They tell people what needs to improve, what needs to change and what could have been done better.

But who tells the leader? Who sits across the table and says, “Perhaps you are looking at this the wrong way”? Who tells the CEO that the decision everyone is applauding may actually be a bad decision? Who has the courage to say, “You may be part of the problem”? And, more importantly, does the leader genuinely want to hear it?

That is where leadership development becomes much more personal.

The higher you rise, the quieter the mirror becomes

Early in our careers, feedback is relatively abundant.

A manager tells us what we are doing well. A colleague challenges our thinking. A customer complains. A mentor gives us advice. Someone tells us that our presentation was poor, our communication was ineffective or our behaviour affected the team.

People become more careful around senior leaders. Employees learn what the leader likes to hear. Meetings become more predictable. The leader speaks first, others respond. A powerful opinion can unintentionally become the “right” opinion simply because it came from the person at the top. Soon, the leader may be surrounded by agreement rather than truth. 

This is one of the great dangers of hierarchical leadership. A leader can begin confusing silence with agreement, compliance with commitment and admiration with trust.

The organisation may still be functioning. Targets may still be achieved. Meetings may still be conducted professionally. But something important has been lost: intellectual friction. And without intellectual friction, leaders can become prisoners of their own assumptions.

The danger of surrounding yourself with the “yes men” 

Imagine a CEO walking into a meeting and saying: “I believe this is the best strategy. Let’s execute it.” Ten people around the table nod. The CEO feels validated. But what did those ten nods actually mean? Did they agree? Were they afraid to challenge the CEO? Did they think someone else would raise the objection? Had previous attempts to challenge the leader been dismissed? Or had the organisation simply learned that disagreeing with the boss was bad for one’s career?

This is why psychological safety matters.

Harvard Business School professor Amy Edmondson’s work on psychological safety has repeatedly highlighted the importance of creating environments where people can speak up, admit mistakes and raise concerns without fear of interpersonal consequences.

Leadership, therefore, isn’t simply about having the confidence to make decisions. It is also about creating the conditions in which someone else can tell you when your decision may be wrong.

That requires humility. And humility is not weakness. It is intellectual strength.

The most dangerous sentence in leadership

There is one sentence that can quietly destroy a leader’s capacity to learn: “I already know.” I already know why sales are falling. I already know why the employee resigned. I already know what the customer wants. I already know why the project failed. I already know what the market is doing. I already know what my people think.

The problem with “I already know” is that it closes the investigation before the evidence has arrived.

Good leadership requires a different question: “What might I be missing?” That single question can transform a leader’s thinking. It moves the mind from certainty to curiosity. And curiosity is one of the most underused leadership capabilities.

Reflection is the missing leadership muscle

Daniel Goleman’s influential Harvard Business Review article “What Makes a Leader?” identified self-awareness as one of the central components of emotional intelligence. Goleman’s research connected emotional intelligence—including self-awareness, self-regulation, motivation, empathy and social skills—with leadership effectiveness. 

Self-awareness, however, is not simply knowing your strengths and weaknesses. It is the ability to observe yourself while you are leading. Why did I react so strongly to that comment?

Why did I dismiss that idea? Why did I interrupt her? Why did I become defensive? Why do I always trust this person? Why do I struggle to trust that person? Why am I convinced this strategy will work? What evidence would prove me wrong? These are uncomfortable questions. But leadership growth often begins precisely where comfort ends.

Research on self-directed leadership development similarly points to three important capabilities: managing emotional reactions to feedback, practising self-reflection and regulating one’s behaviour in response to what is learned. 

In other words, feedback alone isn’t enough. You have to do something with it.

Feedback is information. Reflection turns it into wisdom.

Consider a leader receiving 360-degree feedback.

One colleague says “You don’t listen.”

The leader becomes defensive. “That’s unfair. I listen all the time.”

Another says: “You tend to make decisions before the discussion is complete.”

The leader thinks: “That’s because I am decisive.”

A third says: “People hesitate to challenge you.”

The leader responds: “I have an open-door policy.”

Notice what happened. The leader received feedback three times but learned nothing.

Why?

Because feedback entered the mind as a threat, not as information.

Research on multisource feedback shows that receiving feedback does not automatically produce meaningful improvement. A meta-analysis of 24 longitudinal studies found that improvement following multisource feedback was generally small, and that improvement was more likely when people recognised the need to change, responded positively to feedback, believed change was possible and translated feedback into goals and action. 

That distinction is critical. Feedback is an input. Reflection is the processing system. Action is the output. Without reflection, feedback can become noise.

Don’t ask, “Do you agree with me?”

Ask better questions.

One of the simplest ways for a senior leader to overcome the “yes” culture is to change the questions they ask.

Instead of: “Do you think this is a good strategy? “ask: “What could go wrong with this strategy?”

Instead of: “Do you agree with my decision?” ask: “If you were the CEO, what would you do differently?”

Instead of: “Why isn’t the team performing?” ask: “What might I be doing that is making it harder for the team to perform?”

Instead of: “What do you think about my leadership?” ask: “What is one thing I should stop doing, one thing I should start doing and one thing I should continue doing?”

Questions create space. They give people permission to think. And when leaders genuinely listen to the answers, they create something more valuable than agreement: perspective.

The CEO who becomes the student again

I once heard a senior leader describe his approach to decision-making with a simple philosophy: “Before I make an important decision, I try to argue against myself.” I find this an extraordinarily powerful leadership practice. If you believe an acquisition is right, make the strongest case for why it could be wrong. If you believe a person is the right successor, ask why they might not be. If you believe the market is moving in one direction, investigate evidence that suggests the opposite. If everyone in the room agrees with you, deliberately invite someone to disagree.

This is not indecision. It is decision hygiene.

The best leaders don’t necessarily have fewer biases than everyone else. They develop systems that help them recognise and challenge their biases. They understand that intuition is valuable—but intuition itself is not magic. It is often accumulated experience, pattern recognition and judgement. And experience becomes valuable only when we learn from it.

Intuition needs reflection

We often celebrate leaders who “trust their gut.” There is nothing wrong with intuition. In complex situations, experienced leaders often need to make decisions without having every piece of information.

But there is a difference between intuition and impulse.

Intuition says: “Something doesn’t feel right. Let me investigate.”

Impulse says: “Something doesn’t feel right. Shut it down.”

Reflection creates the gap between the two. That gap is where judgement lives. A leader pauses. Looks at the facts. Examines the assumptions. Listens to other perspectives. Considers the consequences. Then decides.

The pause may take five minutes. Sometimes it may take five days. But that pause can prevent five months of organisational pain.

The mirror and the window

Leadership development requires both a window and a mirror.

The window allows us to look outward—to understand markets, competitors, customers, technology, employees and opportunities.

The mirror allows us to look inward—to understand our assumptions, emotions, behaviours, biases and blind spots.

Too much window and the leader becomes externally obsessed. Too much mirror and the leader becomes self-absorbed. Great leadership requires both.

Look outside to understand the world. Look inside to understand the person interpreting that world. Because every decision passes through the filter of the person making it.

The leader’s most important conversation

Perhaps the most important leadership conversation isn’t the one you have with your board, your customers or your senior management team. It is the conversation you have with yourself after everyone else has left the room.

Ask yourself:

And finally:

What is one thing I can do differently tomorrow?

That is where self-improvement begins. Not with another leadership seminar. Not with another book. Not with another motivational speech. But with an honest conversation with yourself.

Leadership begins when certainty ends

After two decades of speaking about leadership, I have come to believe that one of the greatest measures of leadership maturity is not how confidently a leader can say, “I am right.”

It is how comfortably the leader can say: “I may be wrong. Help me see what I am missing.”

That sentence doesn’t diminish authority. It strengthens it. Because people don’t ultimately trust leaders because they have all the answers. They trust leaders who are willing to search for better answers. The greatest leadership transformation, therefore, may not happen when we learn something new about the world. It may happen when we discover something new about ourselves.

Leadership is not only the ability to lead others. It is the courage to continuously lead yourself.

And sometimes, the most powerful leadership tool is not another strategy, another framework or another decision. It is simply a mirror—and the courage to look into it.
