Definition of Emotional Intelligence: Key Theories and Perspectives

Why do some people, despite average academic records, rise to become exceptional leaders, negotiators, and colleagues? Why do others, brilliant on paper, struggle to handle criticism or connect with a team? The answer often lies not in IQ but in a different kind of intelligence, one that governs how we feel, express, and respond to emotions. This is Emotional Intelligence (EI), a construct that has reshaped how psychologists, administrators, and educators think about human capability since the 1990s.

What is emotional intelligence? 🔗

At its simplest, emotional intelligence is the capacity to recognise, understand, and manage emotions, both our own and those of the people around us. It is the skill set that helps a district officer stay calm during a public grievance hearing, a teacher sense that a student is struggling at home, or a team leader defuse a conflict before it escalates.

The concept was formally introduced by American psychologists Peter Salovey of Yale University and John Mayer of the University of New Hampshire in 1990, who defined it as the ability to monitor one’s own and others’ feelings, to tell them apart, and to use that information to guide thought and behaviour. However, it was the journalist and psychologist Daniel Goleman whose 1995 bestseller brought the term into everyday vocabulary, arguing that emotions matter far more than we had traditionally assumed in predicting life outcomes.

Why a separate kind of intelligence? 🔗

For most of the twentieth century, intelligence was treated as a largely cognitive phenomenon, measured through IQ tests focused on memory, reasoning, and problem-solving. Yet even early thinkers suspected this was incomplete. As far back as 1920, E.L. Thorndike described “social intelligence” as the skill of understanding and managing others, and in 1983 Howard Gardner’s theory of multiple intelligences gave formal space to interpersonal and intrapersonal abilities. Emotional intelligence emerged as a modern refinement of this older intuition, that handling feelings intelligently is a distinct human capacity.

Goleman’s definition: feelings, motivation, and relationships 🔗

Daniel Goleman’s definition has arguably shaped public understanding of EI more than any other. In his influential 1998 Harvard Business Review work, Goleman described emotional intelligence as the capacity for recognising our own feelings and those of others, for motivating ourselves, and for managing emotions well in ourselves and in our relationships.

Notice how this definition stretches across four linked domains: self-awareness, self-motivation, social awareness, and relationship management. It is practical, action-oriented, and deeply relevant to workplaces, classrooms, and governance.

The five (and later four) components 🔗

Goleman’s original framework broke EI into five competencies. His model outlines self-awareness (recognising one’s emotions, strengths, weaknesses, drives, values, and goals), self-regulation (controlling or redirecting disruptive impulses), motivation, empathy, and social skill.

In 2002, working with Richard Boyatzis, Goleman revised this into four clusters. Statistical analyses supported collapsing the twenty-five competencies into twenty, and the five domains into four: Self-Awareness, Self-Management, Social Awareness, and Relationship Management. This refinement matters because it separates what we do with ourselves from what we do with others, a clean architecture that is now standard in leadership training globally.

Why Goleman calls it a “mixed” model 🔗

Goleman’s approach is often categorised as a mixed model because it combines mental abilities with personality-like traits and learned competencies. To Goleman, emotional competencies are not innate talents but learned capabilities that must be worked on and can be developed to achieve outstanding performance. This is an encouraging message for administrators and trainers alike: EI is teachable, not fixed at birth.

Mayer, Salovey, and Caruso: the ability model 🔗

While Goleman popularised EI, Mayer, Salovey, and Caruso kept it anchored to rigorous psychology. Their work treats emotional intelligence as a genuine form of intelligence, measurable much like verbal or logical reasoning.

Their refined four-branch model, most fully developed by 2004, defines EI as a set of four interlinked abilities. They published a four-branch model defining EI as the ability to perceive emotion, use emotion to facilitate thought, understand emotions, and manage emotion. Each branch builds upon the previous one, from the most basic skill of reading a face to the sophisticated ability of regulating feelings in oneself and others.

Breaking down the four branches 🔗

Perceiving emotion is the foundation. It is the ability to identify emotions in faces, voices, postures, and even in art or music. A police inspector who senses fear in a witness’s trembling voice is using this branch.

Using emotion to facilitate thought recognises that feelings can sharpen our thinking. Anxiety before an exam can heighten focus; mild sadness can improve attention to detail. Emotions are not obstacles to good reasoning; sometimes they are the engine of it.

Understanding emotion is the cognitive layer. It involves knowing why we feel what we feel, how one emotion leads to another (frustration to anger, loneliness to withdrawal), and what vocabulary captures the subtleties. A counsellor distinguishing disappointment from grief is exercising this branch.

Managing emotion is the executive function. It is the ability to stay open to feelings, moderate them where useful, and channel them for personal growth and healthy relationships. This is the branch we see most clearly in crisis situations, where a leader who can stay composed while acknowledging the team’s fear helps everyone move forward.

How the two models differ 🔗

The Mayer-Salovey-Caruso ability model treats EI strictly as a mental capacity, measurable through performance-based tests such as the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT), an ability-based test designed to measure the four branches of the EI model of Mayer and Salovey. Goleman’s mixed model, by contrast, folds in competencies, traits, and behaviours that stretch beyond pure ability.

Both views are useful. The ability model gives us scientific precision; the mixed model gives us practical levers for workplace development. Most training programmes today borrow from both.

A third voice: the Bar-On emotional-social model 🔗

No discussion of EI definitions is complete without Reuven Bar-On, the Israeli psychologist who coined the term “emotional quotient” or EQ. Bar-On views emotional intelligence as part of a broader emotional-social intelligence framework. Bar-On describes it as a cross-section of interrelated emotional and social competencies, skills and facilitators that impact intelligent behaviour.

His model covers intrapersonal skills, interpersonal skills, stress management, adaptability, and general mood, and is measured through the Emotional Quotient Inventory (EQ-i). Bar-On’s contribution reminds us that EI is not just about what goes on inside us but also how we adapt to our social worlds, a perspective particularly valuable in diverse, multi-lingual societies.

Why definitions matter for public administrators 🔗

Definitions shape practice. If we treat EI as a fixed ability, we will try to recruit for it. If we treat it as a learnable competency, we will train for it. If we treat it as a broad social capacity, we will build teams around it. Public administrators must deal with emotionally charged situations daily, from disaster response to grievance redressal to inter-departmental negotiations. How we define EI determines how we develop our officers.

The common thread 🔗

Despite their differences, all three major definitions converge on a simple insight: effective emotional functioning involves a constant interplay between feeling and thinking. Emotions supply information; cognition makes sense of that information; and together they guide behaviour. EI has been called the rudder for feeling, thinking, learning, problem-solving, and decision-making.

This is why the field matters beyond the therapist’s office or the HR department. An officer who can read a room, motivate a discouraged team, and stay calm under fire is not simply being “nice.” They are deploying a distinct intelligence that research now takes as seriously as IQ.

Evolution of the concept 🔗

Emotional intelligence has travelled a long road. Thorndike’s social intelligence in 1920, Wechsler’s acknowledgement of non-cognitive factors, Gardner’s multiple intelligences in 1983, Salovey and Mayer’s formal 1990 definition, Goleman’s popularisation in 1995, and the continuous refinement of ability and mixed models since then, each step has added a new layer.

Today, EI is taught in schools, embedded in leadership curricula, and built into civil service training modules. Yet disagreements persist. Substantial disagreement exists regarding the definition of EI, with respect to both terminology and operationalization, and currently there are three main models: the ability model, the mixed model, and the trait model. This ongoing debate is not a weakness of the field; it is a sign of its vitality.

What do you think? Which definition of emotional intelligence resonates most with your own experience, the ability model that treats EI as a pure mental skill, or the mixed model that blends competencies and traits? And can a government department realistically train its officers to strengthen their EI, or is it something each person must build on their own?
