The Dark Side of CliftonStrengths® Self-Assurance 

Self-Assurance is often admired. It lives deep inside the person who remains calm under pressure, trusts their judgement when others hesitate, and moves forward without needing constant validation. In uncertain situations, people with high Self-Assurance can be a stabilising force. They provide confidence when others are overwhelmed by doubt.

At its best, Self-Assurance helps people make tough decisions, back themselves when taking calculated risks, and remain resilient when facing criticism or setbacks.

But every strength has a shadow side.

When Self-Assurance becomes overplayed, confidence can become certainty, certainty can become inflexibility, and independence can unintentionally distance us from the people we need most. The very quality that makes someone decisive can make them appear dismissive. The inner voice that says, “I’ve got this,” can stop them hearing other voices that matter.

And when partnered with Strategic, can become an indecisive burden. When there is no clear ‘right’ choice. A fellow coach with both these, we laughed long and hard at our inability to make train or hotel bookings. The strengths combination spiralled to the bottom of the helpful pile.

Like every CliftonStrengths theme, Self-Assurance is most effective when it operates in partnership with awareness, curiosity, and humility. As it pops up at number 3 in my profile I have spent a lifetime living with and exploring it. And I was really struck by a recent interview of Simon Sinek with Jon Clifton – Sinek describes Self-Assurance as the co-factor that makes him contrary. One of my childhood family names was Contrary Mary. I most certainly did not do what was wanted of me.

What Self-Assurance really is

Gallup describes Self-Assurance as people who feel confident in their ability to manage their own lives. They possess an internal compass. While others seek reassurance from outside sources, those high in Self-Assurance tend to trust their own judgement. 

This doesn’t necessarily mean they are loud, dominant, or extroverted. 

Many highly self-assured people are quietly confident. They simply have a deep belief that they can navigate challenges and make sound decisions. 

Others may experience uncertainty and think: 

What if I get this wrong? 

The person with high Self-Assurance is more likely to think: 

I’ll figure it out. 

This inner confidence, self-belief, can be incredibly energising for teams, particularly during change, ambiguity, or crisis. 

However, problems emerge when confidence becomes disconnected from feedback. 

How Self-Assurance shows up in communication

Communication is often where the dark side of Self-Assurance becomes most visible.

Because people with high Self-Assurance trust their instincts, they may communicate conclusions before others have processed the evidence. They can sound more certain than they intend. They may inadvertently close down discussion rather than invite it.

Common phrases might include:

• I’ve already thought this through.
• Trust me.
• I know this will work.
• Let’s just get on with it.
• We’re overcomplicating this.

From their perspective, they are helping the group move forward.

From someone else’s perspective, they may appear:

• Dismissive
• Arrogant
• Impatient
• Unwilling to listen
• Resistant to challenge

This creates an interesting paradox.

People with Self-Assurance often believe they are being clear and decisive. Others may experience them as overly certain or difficult to influence.

This truly showed up when I wrote a lightning talk on Self-Assurance at a coach’s convention. I called it Puppy training my Self-Assurance and my image/metaphor is of a lion looing in a mirror and seeing a kitten.

This is where conflict often begins.

Not because the Self-Assurance person intends to dominate the conversation, but because their confidence can unintentionally reduce psychological safety for those who process ideas differently.

And another curious thing. Those with Self-Assurance are rarely aware of how it appears to others. I am quite sure if I had a deck of strength descriptors I would not have chosen it. The challenge is that Self-Assurance often experiences itself very differently from how others experience it. Internally, it feels calm, grounded and certain. Externally, it can sometimes look stubborn, dismissive or completely convinced that everyone else is wrong.

If this sounds familiar, you may find our Katalytik white paper on conflict and communication helpful. Many workplace disagreements are not about capability or intention. They emerge because people interpret confidence, challenge, caution, and certainty through different communication lenses.

The hidden challenges of high Self-Assurance

1. Listening without really listening

One of the biggest risks for Self-Assurance is believing you’ve understood before someone has finished speaking. Because you trust your own judgement, you may quickly reach a conclusion about the issue, the solution, or the next step. 

While others are still exploring possibilities, your mind may already be making decisions. 

This can lead to: 

• Interrupting 
• Finishing people’s sentences 
• Closing discussions too quickly 
• Missing valuable information 

The irony is that confidence in your judgement can reduce the quality of your judgement if it stops you gathering all the available data. 

Jedi strategy 

Practise listening for understanding rather than confirmation. 

Before responding, ask: 

“What am I not seeing yet?” 

Intentionally seek information that challenges your initial conclusion. 

The strongest leaders do not simply trust their instincts. They test them.

2. Becoming difficult to influence

Self-Assurance creates resilience. Unfortunately, resilience can sometimes become resistance. 

When someone offers feedback, a highly self-assured person may instinctively filter it through their internal belief system rather than genuinely considering it. We HATE being told something we already know.  

The internal dialogue can sound like: 

• They don’t have the full picture. 
• I’ve already considered that. 
• I know what I’m doing. 

Over time, colleagues may stop offering feedback because they assume it won’t be welcomed. 

This creates a danger zone. 

The stronger your Self-Assurance becomes, the more feedback you actually need. 

Jedi strategy

Create deliberate feedback mechanisms. 

Ask trusted colleagues: 

• What am I not seeing? 
• What am I overestimating? 
• What impact am I having that I may not be aware of? 

Most importantly, listen without defending yourself. 

Remember that impact matters more than intention.

3. Moving faster than everyone else

People with high Self-Assurance often make decisions quickly. The decision feels obvious. 

The route forward feels clear. 

The problem is that other people may still be processing, analysing risks, gathering perspectives, or seeking alignment. 

The Self-Assurance individual can become frustrated: 

Why are we still talking about this? 

Meanwhile the rest of the team may be wondering: 

Why are they rushing? 

This creates tension between speed and inclusion. The Self-Assurance person sees delay. Others see due diligence. Especially if they have Deliberative, Analytical, or Consistency.  

Jedi strategy

Separate decision quality from decision speed. 

Before moving forward, ask: 

• Who needs to be involved? 
• Who needs time to process? 
• What assumptions am I making? 

You do not need to slow your thinking. 

You may need to slow your communication. 

Jedi training

Lean into your other CliftonStrengths and consider if other strengths are disrupting your ability to change gear. For me, my Maximiser and Activator mean that I can become impatient and supercharge my Self-Assurance.

Stop providing answers (quite so quickly). Try asking better questions of others:

• What do you think?
• What’s your recommendation based on the evidence you have?

Value and use their deep talents to provide evidence to strengthen your gut feeling.

4. Appearing arrogant when you feel confident 

One of the hardest aspects of Self-Assurance is that intent and perception can be dramatically different. People may perceive your in the tone of: I have descended from the mountain carrying tablets of truth.  

The gap between intention and impact can be surprisingly large. 

Inside, you feel: 

• Calm 
• Certain 
• Focused 
• Prepared 

Outside, others may see: 

• Overconfidence 
• Dismissiveness 
• Ego 
• Lack of curiosity 

The greater the gap between your confidence and someone else’s confidence, the more likely this misunderstanding becomes. 

This is especially common when working with people who value Harmony, Deliberative, Analytical, Empathy, or Input. 

They may need to be more discussion before reaching the same level of certainty. 

Jedi strategy

Show your thinking rather than simply stating your conclusions. 

Jedi training

Instead of: This is the right answer.  

Try this: Based on X, Y and Z, my current thinking is this. What am I missing? 

Confidence combined with curiosity is far more influential than confidence alone.

5. Carrying too much alone

Many people with high Self-Assurance become fiercely independent. And this can be evident from a very early age. 

After all, they trust themselves. 

They know they can cope. 

They have often succeeded by backing themselves when others doubted them. 

The downside? They can become reluctant to ask for help. 

They may carry excessive workloads, avoid showing vulnerability, and feel responsible for solving everything themselves. Again, this can vary depending on proximal strengths. 

Eventually this can lead to: 

• Burnout 
• Isolation 
• Poor delegation 
• Reduced team development 

The very strength that creates resilience can become a barrier to connection. 

Jedi strategy

Remember that interdependence is not weakness. It is maturity. 

Strong leaders do not prove themselves by carrying everything. They create environments where others contribute, learn, and succeed. 

Jedi training: the mature expression of self-assurance

The mature version of Self-Assurance is not certainty. It is grounded confidence. 

A Jedi Self-Assurance leader can: 

• Trust themselves while remaining open to learning. 
• Make decisions while welcoming challenge. 
• Lead confidently without overpowering others. 
• Stay resilient without becoming isolated. 
• Hold strong views without becoming attached to them. 

Being confident does not require being right all the time.

Confidence is not the absence of doubt. 

It is the ability to move forward while remaining willing to learn. 

Coaching questions for self-reflection 

If Self-Assurance is one of your dominant strengths, consider the following questions. 

Exploring Your Impact 

• How does my confidence affect other people? 
• When might my certainty unintentionally silence others? 
• What feedback do I regularly dismiss or ignore? 

Exploring Your Blind Spots 

• What assumptions am I making? 
• Where might I be overestimating my understanding? 
• Who sees things differently from me and why? 

Exploring Relationships 

• How often do I genuinely invite challenge? 
• Do people feel safe disagreeing with me? 
• What signals do I unintentionally give when someone questions my view? 

Exploring Growth 

• When was the last time I changed my mind because of someone else’s perspective? 
• How could I combine confidence with curiosity more effectively? 
• What would greater humility look like in practice? 

The strengths that most challenge Self-Assurance 

Every theme has a natural foil. The strengths most likely to challenge Self-Assurance often include: 

• Analytical: What’s the evidence? 
• Deliberative: What could go wrong? 
• Input: What information are we missing? 
• Harmony: How will this affect others? 
• Empathy: How are people feeling about this? 
• Context: What can we learn from the past? 
• Relator: Who needs bringing with us? 

These are the strengths we need to partner with.  Because the people we perceive as slowing us down are often preventing us driving confidently in the wrong direction. 

Final thought

Self-Assurance is a powerful strength. But it is not confidence. It is in danger of being confidence untethered from external validation. 

Its greatest gift is crafting confidence and self-belief in others. It helps people navigate ambiguity, make courageous decisions, and remain steady when others lose confidence. Many successful leaders, entrepreneurs, academics, and innovators rely on Self-Assurance to challenge convention and move ideas forward. 

Yet the greatest risk of Self-Assurance is not confidence. 

It is believing that confidence alone is enough. 

The dark side emerges when certainty replaces curiosity, when independence replaces collaboration, and when conviction stops us listening. 

The Jedi version of Self-Assurance trusts its own inner compass while remaining open to other maps. That’s when Self-Assurance becomes more than confidence. It becomes wisdom. 

And wisdom is what allows confidence to inspire others rather than intimidate them. 

Reflection Challenge 

Over the next week, pay attention to the moments when you feel most certain. 

Ask yourself one simple question: 

Am I demonstrating confidence, or am I closing down curiosity? 

Your answer may reveal the difference between the dark side and the Jedi path of Self-Assurance.
