In 1995, Daniel Goleman popularized a concept in his book Emotional Intelligence that has shaped leadership research ever since. His central claim: IQ accounts for at most 20% of the difference between more and less successful leaders. The remaining 80% comes down to emotional intelligence.
That may sound like a soft skill. It is one of the hardest.
The 5 dimensions of emotional intelligence, according to Goleman
Self-awareness
The ability to accurately recognize your own emotions, strengths, weaknesses, and motives. Leaders with high self-awareness have fewer illusions about themselves and tend to build stronger teams as a result.
Self-regulation
The ability to manage impulses, regulate your mood, and reflect before reacting. Leaders who can regulate themselves don't lead based on their mood. They lead based on judgment.
Motivation
An intrinsic drive that goes beyond external rewards. Leaders with high EI hold themselves to their own standards and maintain them whether or not anyone is watching.
Empathy
The ability to recognize and take into account what others are feeling without taking those emotions on as your own. Empathy isn't sympathy. It is the foundation of trust.
Social skill
The ability to build relationships, develop networks, and move people toward shared goals. Leadership isn't about giving orders. It's about persuading, connecting, and enabling.
What research says about EI and leadership success
EI in virtual teams: a particular challenge
In virtual and hybrid work environments, emotional intelligence becomes even more important. Why? Because many of the nonverbal cues that make up an estimated 55% of in-person communication (Mehrabian) are missing. Leaders with strong EI find ways to bridge that gap. Leaders without it may not notice the problem until the team is no longer functioning effectively.
Research suggests that trust and psychological safety are even more important in virtual teams than in in-person settings, and both depend heavily on the emotional intelligence of the leader.
"In a very real sense we have two minds, one that thinks and one that feels." — Daniel Goleman, Emotional Intelligence
What emotionally intelligent leaders actually do differently
- They don't simply react to other people's emotions — they respond to them
- They give feedback that people can actually hear because it is delivered with respect
- They recognize stress in the team before it turns into a crisis
- They address conflict without sacrificing the relationship
- They are consistent, so the team knows what to expect from them
- They motivate through meaning, not pressure
Can EI be trained?
Yes. This is one of the most important findings from neuroscience: the brain is plastic. Emotional intelligence isn't fixed. It is a skill that can grow through deliberate practice, feedback, and reflection. What can't be trained is the willingness to do the work.
Leaders who aren't willing to admit that they have limitations will rarely become more emotionally intelligent. Self-reflection is the prerequisite. And self-reflection begins with a willingness to accept uncomfortable truths about yourself.
This article will be expanded in a future version with findings from Irene Flaming's master's thesis, Emotional Intelligence in Virtual Teams (University of Bremen, grade A+). The thesis examines which EI competencies correlate most strongly with leadership success in virtual team settings.
Emotional intelligence isn't softness. It may be the hardest leadership skill there is because it requires self-reflection, honesty, and consistent practice. Leaders who have it retain their teams, resolve conflicts, and make better decisions. Leaders who don't often don't understand why their team isn't following them.
