We talk a lot about what makes a good leader—communication, decision-making, strategic thinking. There’s lots of aspirational traits to – being ‘visionary’ or ‘inspiring’ or that buzzword at the moment: bringing ‘clarity’.

But there’s one capability that sits underneath all of those, and without it, the rest doesn’t land particularly well.

That’s self-awareness.

It’s not flashy, and it’s not always comfortable. But in practice, it’s often the difference between a leader people respect and one people quietly work around.

What is self-awareness in leadership?

Self-awareness is simply having a clear and honest understanding of how you operate—and how that impacts other people.

That includes things like:

your strengths and blind spots
how you communicate under pressure or in general
your emotional triggers (and how they show up)
the assumptions you make about others
how your behaviour is experienced by your team

Most leaders have some level of self-awareness. The gap is usually in how accurate it is—and whether they’re willing to do anything with it.

Why self-awareness in leadership matters more than people think

Leadership is relational. You’re not just delivering outcomes—you’re doing it through people.

If you don’t understand how you come across, you’re essentially leading with a blind spot.

Self-aware leaders tend to:

communicate with more intention
build stronger trust with their teams
take feedback on board without getting defensive
adjust their approach depending on the person or situation.

Leaders who lack self-awareness often don’t realise the impact they’re having, and that’s where things start to unravel.

An illustration: two leaders, same team

A simple way to see this in action is to compare two leaders in the same situation.

Same organisation. Same expectations. Same pressure. The only real difference is their level of self-awareness.

Sam …

Sam would describe themselves as a strong, results-focused leader. They value efficiency and being direct.

From their perspective, they’re clear and to the point.

From the team’s perspective, it feels different.

People get cut off in meetings
Feedback comes across as criticism
Questions are taken as pushback
There’s a lot of checking and follow-up

Sam doesn’t see an issue with their approach. If anything, they think the team needs to lift.

So, they double down with more pressure, more oversight, less patience.

Over time:

people stop speaking up
ideas dry up
engagement drops
performance diminishes.

Sam notices the decline, but attributes it to the team rather than their own leadership.

Alex

Alex is just as focused on results. That’s not the difference.

The difference is that Alex has a better understanding of themselves.

They know they can come across as intense when things are busy.
They know they tend to jump in quickly.
They’re aware that how they intend to show up isn’t always how they’re experienced.

So, they make some deliberate adjustments.

They pause before responding.
They let people finish their point.
They ask questions instead of jumping to conclusions.
They check how their message has landed.

They also actively ask for feedback, even when it’s a bit uncomfortable.

It doesn’t happen overnight, but over time:

people contribute more
issues get raised earlier
trust builds
performance improves.

The difference isn’t personality

It’s easy to look at those two and think one is just “nicer” than the other. That’s not really it. The difference is awareness—and what they do with it –

Sam doesn’t recognise the impact they’re having.
Alex does, and adjusts accordingly.

That’s the difference between an OK leader and a great leader. And because of this difference, Alex’s team is likely to perform better, have higher engagement scores, less turnover and a much reduced chance of employees experiencing high stress and burnout.

Where leaders can get it wrong: the ‘authenticity trap’.

This is a trap that can show up once leaders start developing self-awareness. They become aware of their style… and then use it to justify staying the same.

You’ll hear things like:

“I know I’m direct”
“That’s just my style”
“People need to get used to it”

Sometimes it’s framed as authenticity. But being authentic doesn’t mean being fixed.

As I’ve covered in my article on authentic leadership, real authenticity isn’t about saying “this is just who I am” and making everyone around you put up with your bad behaviour. It’s about being genuine and taking responsibility for your impact on the people around you.

If your behaviour is creating friction, disengagement, or confusion, the answer isn’t to defend it. It’s to adjust it.

Self-awareness gives you the insight, but it only becomes useful when you act on it. So how do you do that?

How leaders actually build self-awareness

This isn’t something that just develops over time on its own. It usually needs a bit of structure and external input. We like to take a scientific approach to it, because believe it or not, data can help you to understand and change your behaviour. So we use some incredibly effective measurement tools.

Psychometric assessments

Psychometric assessments or psychometric testing is a self-report tool. It works well if the questions are answered honestly, rather than what the person thinks is socially acceptable (in fact these assessments are so clever they can even tell if a person is answering questions inconsistently or in a ‘socially acceptable’ way!). They help a leader (or potential leader) to understand themself and –

help leaders understand their natural preferences
highlight communication styles and tendencies
give a starting point for reflection.

360-degree feedback

This is where the leader gets a richer picture. 360-degree feedback helps leaders to understand how others experience their behaviour –

providing input from managers, peers, and direct reports
highlighting gaps between intention and impact
bringing to the surface things leaders wouldn’t otherwise see

Combining measurement tools

Neither of these are magic on their own, but used well and with follow-up training and coaching, they can significantly speed up the process. Combining the two tools – psychometric testing and 360-degree feedback – becomes exponentially more powerful when you use the same measurement tools for both. This will show the gaps between how the leader thinks they are showing up, and how others are experiencing them.

A good leadership development programme will use one of these tools. A great leadership development programme will use both because they give leaders something concrete to work with.

Self-awareness is only the starting point - social intelligence takes it further

Understanding yourself is important, but it’s not the end goal.

The real shift happens when leaders start to apply that awareness in how they interact with others.

That’s where social intelligence training comes in.

It helps leaders:

read the room more effectively,
understand different working styles,
recognise how their behaviour impacts different people,
adapt their approach to get better outcomes.

In simple terms, self-awareness is about understanding yourself.

Social intelligence is about using that understanding to work better with others. Our SOCIAL STYLE ™ training and coaching gives you all of these skills.

Bringing it all together

Self-awareness isn’t a “nice to have” for leaders – it’s foundational.

Without it, even capable leaders can create unnecessary friction and disengagement.

With it, things tend to run a lot more smoothly:

communication improves
trust builds
people contribute more
performance lifts.

It’s not about being perfect. It’s about being aware enough to notice what’s going on, and willing enough to adjust.
