Why Emotional Intelligence Matters More Than IQ—and How DISC Helps Leaders Actually Grow It

Most business leaders I work with are smart.

High performers.
Technically competent.
Well-educated.
Decisive.

Yet many of them are frustrated.

Not because they lack strategy or intelligence—but because people don’t always respond the way they expect.

Teams shut down.
Feedback gets misunderstood.
Good intentions land poorly.
The same conflicts repeat—just with different people.

This is the leadership problem Daniel Goleman surfaced from his book Emotional Intelligence years ago—and it’s even more relevant today. The Real Problem: IQ Gets You There, EQ Determines How Far You Go

Research consistently shows something surprising to many leaders:

• Up to 80% of success in work and life is attributed to emotional intelligence, not IQ or technical skills
• Emotional intelligence accounts for nearly 58% of job performance across roles
• 90% of top performers have high EQ, while only about 20% of low performers do
• 71% of employers value EQ more than IQ when evaluating talent

In leadership roles, the numbers are even more striking:

Studies suggest up to 85% of leadership effectiveness is linked to emotional intelligence—how leaders manage themselves and relate to others.

In other words:
IQ may get you hired.
EQ determines whether people trust you, follow you, and stay.

Why Emotional Intelligence Still Feels Hard to Apply

Most leaders agree that emotional intelligence matters.

They know they should:

• Be more self-aware
• Manage emotions better
• Show empathy
• Communicate well

But here’s what I hear in coaching sessions:

“I know EQ is important—but what does that actually look like in real conversations?”

That’s the gap.

EQ explains the goal.
But without a practical tool, it often stays theoretical.

This is where DISC changes everything.

DISC: The Bridge Between Emotional Intelligence and Daily Leadership

DISC doesn’t measure feelings.
It measures observable behavior—how people communicate, decide, and react under pressure.

That makes emotional intelligence visible and actionable.

I often tell leaders:

EQ is the capability.
DISC is the operating system that helps you practice it daily.

A Coaching Story: When Good Intentions Create Bad Impact

I once coached a business owner who was fast, decisive, and results-driven.

Strong D-style tendencies.

From his perspective:

“I’m just being clear and efficient.”

From his team’s perspective:

“We feel pressured. Afraid to speak up. Always on edge.”

When he saw his DISC profile, he paused.

Then he said:

“So this is how I come across.”

That moment wasn’t about personality—it was self-awareness.

He didn’t need to slow the business down.
He didn’t need to soften standards.

He simply learned to:

• Pause before responding
• Ask one clarifying question
• Adjust tone without losing clarity

Performance stayed high.
Trust went up.
Turnover went down.

That’s EQ growth—made practical through DISC.

How DISC Develops Emotional Intelligence in Leaders

1. DISC Builds Self-Awareness

Emotional intelligence begins with knowing yourself.

DISC helps leaders answer:

• How do I naturally communicate?
• How do I react under stress?
• How might others experience me—even if I don’t intend it?

Awareness stops being abstract and becomes specific.

2. DISC Strengthens Self-Regulation

EQ requires managing emotional reactions.

DISC shows leaders:

• Where strengths get overused
• Which behaviors escalate tension under pressure

Instead of “control your emotions,” leaders learn:

“This is my pattern—and here’s how to adjust it.”

That’s regulation with clarity.

3. DISC Turns Empathy Into a Skill

Empathy isn’t about being soft—it’s about being effective.

DISC teaches leaders how different people feel respected:

• D styles value results and decisiveness
• I styles value recognition and energy
• S styles value stability and reassurance
• C styles value logic and accuracy

Adapting communication becomes practical empathy, not guesswork.

4. DISC Improves Influence and Social Skill

Instead of asking:

“Why are they so difficult?”

Leaders begin asking:

“How should I adjust my communication so they can hear me?”

That question alone changes:

• Feedback conversations
• Meetings
• Conflict resolution
• Team morale

A Personal Leadership Reflection

Early in my own leadership journey, I believed clarity meant saying more.

DISC taught me something humbling:
Some people needed less detail.
Others needed more structure—not more passion.

When I stopped communicating my way and started leading their way:

• Resistance dropped
• Alignment improved
• Leadership felt lighter

That’s when emotional intelligence stopped being an idea—and became a habit.

The Simple Plan for Leaders 

Here’s the clear path:

1. Understand emotional intelligence (the goal)
2. Use DISC to identify behavior patterns (the mirror)
3. Practice intentional adjustments daily (the discipline)

No hype.
No personality labeling.
Just better leadership choices—consistently applied.

What Success Looks Like

Leaders who combine EQ and DISC experience:

• Fewer emotional blind spots
• Stronger trust with teams
• Clearer communication
• Healthier culture
• Better results

You don’t become perfect.
You become intentional.

Final Thought

IQ helps you solve problems.
EQ helps you lead people.
DISC helps you practice EQ—one conversation at a time.

If leadership feels heavier than it should, the issue may not be strategy or intelligence.

It may simply be how you show up.

And that’s something you can grow.
