Emotional Intelligence (EQ) is the ability to understand and manage emotions in yourself and others. Based on Daniel Goleman's Emotional Intelligence model (1995), the four EQ competencies are: self-awareness (knowing your emotions), self-management (controlling impulses), social awareness (empathy), and relationship management (influencing others). Essential for leadership, teamwork, and conflict resolution.
Emotional intelligence is the ability to recognise, understand, manage, and effectively use emotions in yourself and others. The concept was formalised by psychologists Peter Salovey and John Mayer in 1990 and popularised by Daniel Goleman in his 1995 book "Emotional Intelligence: Why It Can Matter More Than IQ."
The idea is not new. What Goleman did was synthesise decades of research showing that cognitive intelligence (IQ) alone does not fully predict success in real-world situations. IQ predicts academic performance and the ability to handle cognitive complexity, but many other factors also contribute to career and life outcomes, including emotional competencies, social skills, motivation, and opportunity.
This does not mean IQ is irrelevant. You need a certain level of cognitive ability to function in a demanding role. But above that threshold, the differentiator between average performers and exceptional ones is almost always emotional intelligence.
The data on EQ and workplace performance is substantial:
TalentSmart tested emotional intelligence alongside 33 other workplace skills and found that EQ was the strongest predictor of performance, accounting for 58% of success across all job types. This was consistent across industries, roles, and seniority levels.
The Hay Group studied leaders at 15 global companies and found that those in the top 10% of EQ scores delivered 20% more revenue than those with average EQ.
Google's Project Oxygen analysed what makes a great manager and found that technical expertise ranked last among eight key qualities. The top qualities were all emotional intelligence competencies: being a good coach, communicating and listening well, being interested in team members' lives, and creating an inclusive environment.
The pattern is consistent: above a baseline of technical competence, emotional intelligence is a strong differentiator between good performers and great ones. The higher you climb in an organisation, the stronger the effect, because senior roles involve more interpersonal complexity, influence, and stakeholder management.
Goleman's framework breaks emotional intelligence into four domains, each containing specific competencies:
The foundation of all emotional intelligence. Self-awareness is the ability to recognise your own emotions as they happen, understand their causes, and know how they affect your behaviour and decisions.
Why it matters: Self-awareness is the prerequisite for every other EQ skill. You cannot manage emotions you do not recognise. You cannot empathise with others if you are blind to your own emotional state.
Research by organisational psychologist Tasha Eurich found that although 95% of people believe they are self-aware, only about 10-15% actually are. This gap is one of the biggest obstacles to professional development.
The ability to regulate your emotions, control impulsive reactions, and adapt to changing circumstances without being derailed.
Why it matters: Every professional faces situations that trigger strong emotions: unfair criticism, sudden changes, difficult colleagues, high-pressure deadlines. Self-management does not mean suppressing emotions. It means choosing your response instead of being controlled by your reaction.
The ability to read other people's emotions, understand social dynamics, and pick up on unspoken signals in group settings.
Why it matters: Effective collaboration requires understanding what other people are feeling and why. Leaders with high social awareness build trust faster, manage conflict more effectively, and create environments where people feel psychologically safe.
The ability to use your awareness of your own emotions and others' emotions to build strong relationships, communicate clearly, and influence positively.
Why it matters: Relationship management is where EQ becomes visible. It is the competency that directly drives teamwork, leadership effectiveness, and career advancement.
Goleman's research found that leadership effectiveness depends on emotional intelligence more than any other factor. He identified six leadership styles, each rooted in different EQ competencies:
The most effective leaders switch between styles depending on the situation. This requires a broad EQ skill set. Leaders who rely on a single style, usually commanding or pacesetting, consistently underperform compared to leaders who can adapt.
A 20-year longitudinal study by the Center for Creative Leadership found that the primary cause of executive derailment (being fired, demoted, or plateauing below potential) is deficits in emotional competence: difficulty handling change, inability to work in a team, and poor interpersonal relationships. These are all EQ failures, not IQ failures.
Low emotional intelligence is not always obvious. Some of the most technically brilliant people struggle with EQ, and their skill in other areas can mask the problem for years. Common signs include:
If you recognise these patterns in yourself, that recognition is itself a sign of self-awareness, which means you have the foundation to develop the other skills.
EQ is a skill set, not a fixed trait. Here are evidence-based approaches to developing each domain:
Organisations increasingly assess EQ during hiring, particularly for leadership and client-facing roles.

Yes. Unlike IQ, which is largely fixed by early adulthood, emotional intelligence is a set of skills that can be developed at any age. Research by Goleman and the Hay Group found that targeted EQ development programmes produce measurable improvement in self-awareness, empathy, and emotional regulation. The key is sustained practice, not just reading about it. Like physical fitness, EQ develops through consistent effort over time.
Yes. IQ predicts your ability to learn technical skills and handle cognitive complexity. EQ predicts how well you work with people, handle stress, navigate office politics, and lead teams. Google's Project Oxygen found that technical expertise ranked last among eight key qualities of great managers - the top qualities were all EQ competencies. Both IQ and EQ contribute to career success in different ways.
EQ scores vary depending on the assessment used, so there is no single universal average. What is consistent across research is that most people overestimate their own emotional intelligence. Tasha Eurich's research found that while 95% of people believe they are self-aware, only 10-15% actually demonstrate strong self-awareness. The gap between perceived EQ and actual EQ is one of the most consistent findings in the field.
In theory, no, but EQ skills can be misused. Someone with high social awareness but low ethical standards can manipulate others effectively. This is sometimes called "dark EQ." Genuine emotional intelligence includes moral reasoning and empathy, not just the ability to read people. The goal is emotional intelligence in service of authentic connection and ethical behaviour.
Self-report questionnaires like our EQ quiz give you a useful baseline by measuring how you perceive your own emotional skills. For a more complete picture, 360-degree assessments (where colleagues, managers, and direct reports rate your EQ) are more accurate because EQ is about how you affect others, not just how you see yourself.
