Why strong performers don’t always become strong leaders

When being good at the job isn’t the same as leading it - it’s more about range...

A slightly uncomfortable read on why capability isn’t enough...

You know that thing that happens when someone brilliant gets promoted…

They’ve been exceptional at something:

• Closing deals

• Solving complex problems

• Being the person everyone goes to

So the organisation does the obvious thing. They give them a team.

And then something shifts.

Not dramatically. Not overnight. But you start to notice it:

• Conversations feel tighter

• Decisions feel heavier

• People stop bringing things early

• The leader leans harder into what used to work

And quietly, performance flattens.

The assumption sitting underneath it

No one really says it out loud, but it’s there:

If you’re great at the work, you’ll be great at leading the work.

It sounds reasonable. Until you watch it play out.

Because leading isn’t just more of the same work. It’s a different environment entirely.

Two very different worlds

One of the most useful ideas in Epstein’s book is the distinction between environments.

Some are predictable:

• You act

• You get feedback quickly

• You refine

• You repeat

Others aren’t like that at all.

In these environments:

• Feedback is delayed or unclear

• People react differently than expected

• What worked last time… doesn’t quite land this time

Leadership lives here.

Not in repetition — but in variation.

Not in certainty — but in judgement.

Where it starts to go wrong

If you’ve built your success in a more predictable world, you’ve likely learned something powerful:

A way that works.

A way to:

• Solve

• Decide

• Move things forward

And because it works, you trust it. You refine it. You rely on it.

Then you step into leadership… and keep using it.

What others might experience

This is the bit that’s easy to miss. Because from the leader’s side, nothing feels “wrong”.

They’re doing what’s always worked. But from the outside, it can land differently:

• Clarity starts to feel like control

• Expertise starts to shut down input

• Efficiency starts to skip over people

• Consistency starts to feel rigid

The behaviour hasn’t changed much.

The context has.

And that changes the impact.

This is where “range” becomes useful

Epstein talks about range in terms of experience and thinking.

But in leadership, it shows up somewhere more immediate:

In behaviour.

Not just:

• What you know

But:

• How many different ways you can respond when the moment shifts

The real gap

Most struggling leaders aren’t lacking capability. If anything, they have too much certainty in one way of operating.

You’ll hear it in how they describe themselves:

• “I’m quite direct”

• “I’m very collaborative”

• “I tend to empower people”

Which sounds like self-awareness.

But it’s often something else.

A default. A reliable place they go — regardless of what the moment actually needs.

A different way of looking at it

At Noggin, we’d describe this as range in the moment.

Questions like:

• What becomes easier for you to access?

• What quietly drops out when things get tense?

• How many options are genuinely available to you right now?

Because leadership isn’t about choosing the right style.

It’s about having enough range to choose at all.

And under pressure, that range often narrows — we go back to what’s familiar.

The consistency myth

There’s a common idea that great leaders are consistent.

It sounds right. But watch closely, and something else is happening.

The strongest leaders aren’t consistent in behaviour. They’re consistent in calibration.

They might be:

• Direct in one moment

• Quiet in another

• Challenging here

• Supportive there

Same person. Different response.

Because the situation is different.

So what’s actually happening?

When specialists struggle in leadership, it’s rarely about intelligence or effort.

It’s usually this:

They’ve built depth…

…without needing to build flexibility.

So when the environment changes, their behaviour doesn’t.

The shift

If leadership is unpredictable (and it is), then the question changes.

Not:

How do we make better leaders?

But:

How many options does this leader have when things don’t go to plan?

Because in those moments:

• One way of operating feels safe

• Multiple ways of operating creates choice

And choice is what allows adjustment.

Final thought

There’s nothing wrong with having a strong way of operating.

It’s often what got you here.

The risk is when it becomes the only way available. Because at that point:

You’re no longer responding to the situation.

You’re asking the situation to respond to you.

And that’s usually where leadership starts to break.
