Emotional intelligence refers to the ability to perceive, understand, and manage one’s own emotions and relationships. It involves being aware of emotions in oneself and others and using this awareness to guide thinking and behavior. Emotionally intelligent individuals can motivate themselves, read social cues, and build strong relationships.
A highly prominent framework used to describe these specific skills is the RULER acronym. Yale psychologist Marc Brackett and colleagues developed RULER (Brackett, Rivers, & Salovey, 2011). It breaks emotional intelligence down into five distinct abilities.
- Recognizing emotions in oneself and others by reading facial expressions, body language, and vocal tones.
- Understanding the origins and consequences of those feelings.
- Labeling emotions with precise and accurate words.
- Expressing emotions appropriately across different contexts, cultures, and relationships.
- Regulating emotions by employing effective strategies to deal with everyday feelings.
RULER turns these ideas into a whole-school curriculum for teaching emotional skills. School-based social and emotional learning programmes like it have strong support.
A meta-analysis of 213 such programmes, covering more than 270,000 students, found real gains in social-emotional skills. Academic achievement rose too. It climbed by an average of 11 percentile points (Durlak, Weissberg, Dymnicki, Taylor, & Schellinger, 2011).
Some researchers propose that emotional intelligence can be learned and strengthened, while others argue it is an inborn characteristic.
Key Takeaways
- Three Models: EI might mean a cognitive ability, a set of workplace skills, or a personality trait, depending which psychologist you ask.
- RULER Framework: recognizing, understanding, labeling, expressing, and regulating emotions is a popular five-step way schools and workplaces teach EI.
- Self-Awareness Gap: most people believe they are self-aware, yet research suggests only 10 to 15 percent genuinely are (Eurich, 2018).
- Modest Effects: EI predicts job performance and wellbeing, but the effect is real and useful, not the “EQ beats IQ” claim popular books make.
- Trainable, Mostly: ability- and competency-based EI can be developed through practice, though trait EI, rooted in personality, is more stable.
- A Dark Side: the same skills that build rapport and read others can be turned to manipulate or deceive them.
- Measurement Divide: ability tests score correct answers; self-report questionnaires ask you to rate yourself. The two barely agree.
Intrapersonal & Interpersonal Dimensions
Emotional intelligence is not a singular, static construct; rather, it is a dynamic set of both intrapersonal (self-focused) and interpersonal (other-focused) skills.
The ability to express and manage emotions is essential, but so is the ability to understand, diagnose, and react to the emotions of others.
Intrapersonal Skills
Emotional intelligence begins with self-awareness: assessing your current state of arousal, evaluating your pleasantness or unpleasantness, and identifying where your feelings are coming from.
A key component of this is emotional granularity, the ability to precisely define your emotional state. Precision matters.
Highly emotionally intelligent people understand the differences between being “anxious” (worrying about future uncertainty), “stressed” (too many demands, not enough resources), and “overwhelmed”.
Connecting a feeling to its specific cause lets you pick the right regulatory strategy. Anxiety about the future may call for a cognitive strategy, while general stress may be eased by a breathing exercise.
Interpersonal Skills
On an interpersonal level, emotional intelligence involves picking up on the emotions, energy, and personality traits of colleagues, romantic partners, and children to anticipate their needs.
Social interactions are constant exercises in co-regulating each other’s emotions.
When interacting with others, emotionally intelligent people act as “emotion coaches” or “feelings mentors.” They stay non-judgmental, show empathy and compassion, and practice active listening.
Active listening is a core part of this. It means focusing entirely on the speaker instead of judging them or planning a clever reply.
Examples of Emotional Intelligence
Emotional intelligence is “the ability to monitor one’s own and others’ feelings and emotions, to discriminate among them and to use this information to guide one’s thinking and actions” (Salovey & Mayer, 1990, p. 189).

These four skills are often called the ability model of emotional intelligence, developed by psychologists John Mayer and Peter Salovey (Mayer & Salovey, 1997). A separate account, Daniel Goleman’s mixed model, treats EI as a broader set of workplace competencies rather than a pure ability.
The two rarely overlap. Someone can score well on a hands-on ability test yet rate themselves poorly on a self-report questionnaire, or the reverse.
Emotional Awareness (Understanding Emotions)
Self-awareness, or the ability to recognize and comprehend one’s own emotions, is a vital emotional intelligence skill.
Beyond acknowledging one’s feelings, however, is being conscious of the effect of one’s actions, moods, and emotions on other people.
According to research by Tasha Eurich, an organizational psychologist, 95% of individuals believe they are self-aware. Eurich published this finding in 2018. Still, only 10 to 15 percent genuinely are, which can cause problems for the people one interacts with.
To become self-aware, one must be capable of monitoring one’s emotions while recognizing different emotional reactions and correctly identifying each distinct emotion.
Self-aware individuals also can recognize the connections between the things they feel and how they act.
Recognizing and Differentiating Complex Emotions
A foundational example of emotional intelligence is the practice of emotional granularity, which is the ability to precisely define your internal state rather than using broad, generic labels.
- Identifying the root cause: An executive or student might claim they are experiencing general “stress” or “anxiety,” but upon deeper reflection, they realize they are actually feeling “envious” of a colleague’s success or resources.
- Uncovering hidden emotions: A father who is chronically irritable and critical of his new wife’s decision to babysit her grandchildren might appear simply angry. However, an emotionally intelligent breakdown reveals that he is actually experiencing jealousy and a fear of losing her attention.
- Noticing secondary emotions: Emotionally intelligent individuals recognize when they are having a reaction to a reaction, such as a parent who feels angry at a child’s misbehavior, but then subsequently feels guilty or ashamed about having experienced that anger.
Here are some tips on improving one’s self-awareness:
-
Ask for constructive feedback from others.
-
Keep a journal of one’s thoughts and feelings.
-
Practice mindfulness – try meditating.
-
Pay careful attention to one’s thoughts and emotions.
-
Pursue one’s passions and do what makes one happy.
-
Learn new skills and set goals for oneself.
-
Reflect on one’s experiences and be grateful.
-
Use positive self-talk daily.
-
Work on building a growth mindset.
Emotional Self Regulation (Managing Emotions)
Emotionally intelligent individuals do not suppress their feelings, but they proactively manage how those feelings dictate their behavior.
This does not mean taking emotions out of sight and essentially “locking” them away, hence hiding one’s true feelings.
It just means waiting for the right time and place to express them. Self-regulation is all about communicating one’s emotions appropriately in context. A reaction tends to be involuntary.
The more in tune one is with one’s emotional intelligence, the easier one can transition from an instant reaction to a well-thought-out response.
People with healthy self-regulation skills also tend to have heightened conscientiousness. They reflect on how they influence others and take accountability for their actions.
Here are some tips on improving one’s self-regulation:
-
The intentional pause: Before engaging in a coping mechanism, such as stress-eating a bowl of ice cream, a person might pause to ask, “Is this physical hunger or emotional hunger?” and actively assess how the ice cream is temporarily feeding a feeling of stress rather than solving it.
-
Aligning with values during an emotional storm: If a person discovers a profound betrayal, such as being cheated on, their immediate emotional impulse might be a red haze of rage telling them to run the betrayer over with a car. Emotional intelligence involves looking at that intense jealousy and anger with curiosity, and asking, “How do I behave in line with my deeply held values in this situation?” rather than surrendering to destructive urges.
-
Accepting impermanence: A highly emotionally intelligent five-year-old child who recognizes he is in a “blue” mood (feeling unpleasant and low energy) might calmly tell an adult that he does not need a strategy to fix it, because he knows the emotion is impermanent and will naturally pass.
Social Empathy (Perceiving Emotions)
Empathy, or the capability to comprehend how other people are feeling, is crucial to perfecting emotional intelligence.
However, it involves more than just being able to identify the emotional states of others. It also affects one’s responses to people based on this knowledge.
While empathy involves understanding or relating to another’s pain, empathy without emotional intelligence can lead to compassion fatigue, where a person becomes entirely lost in someone else’s suffering. Compassion fatigue is a genuine risk.
Emotionally intelligent individuals recognize when they are becoming overwhelmed by another’s feelings and know how to pull back and regulate themselves.
Furthermore, emotional intelligence recognizes that endlessly talking about feelings without moving toward strategies or solutions is often counterproductive, as it merely rehearses the negative emotion.
Instead, an emotionally intelligent listener uses compassionate questioning to help the person gain perspective, eventually guiding them toward a path of feeling better.
Here are some tips on improving social empathy:
-
Be willing to share emotions.
-
Listen to other people.
-
Practice meditation.
-
Engage in a purpose like a community project.
-
Meet and talk to new people.
-
Try to imagine yourself in someone else’s place.
Social Skills (Using Emotions)
The ability to interact well with others is another vital aspect of emotional intelligence.
Solid social skills allow people to build meaningful relationships with others and develop a more robust understanding of themselves and others. These skills can be learned.
Proper emotional understanding involves more than just understanding one’s own emotions and those of others. One also needs to put this information to work in one’s daily interactions and communications.
In the workplace or professional settings, managers benefit by being able to build relationships and connections with employees.
Workers benefit from developing a solid rapport with leaders and co-workers. Some prefer to avoid conflict, but it is crucial to address issues as they arise correctly.
Research shows that every unaddressed conflict can waste almost eight hours of company time on unproductive activities, damaging resources and morale.
Essential social skills include active listening, verbal communication, nonverbal communication, leadership, and persuasiveness.
Here are some tips on improving social skills:
-
Ask open-ended questions.
-
Find icebreakers that will help start conversations.
-
Practice good eye contact.
-
Practice active listening with the entire body.
-
Notice other people’s social skills.
-
Show interest in others and ask them personal questions.
-
Watch one’s body language and that of others.
Emotional Intelligence in the Workplace
Emotional intelligence includes showing genuine compassion, empathizing with the needs of individuals, and encouraging the ongoing personal growth of individuals.
When a leader takes into account the emotions of their followers, they then learn how to best engage with them.
1. Lending a Compassionate Ear to a Frustrated Co-Worker
Employees will inevitably get upset, have bad moods, argue, and just generally have bad days.
In practice, compassion, understanding, and awareness are definite signs of emotional intelligence.
Awareness of and reacting to other people’s emotional states shows an understanding that all humans experience intense emotions and says that a person’s feelings matter.
2. Listening to Others Respectfully
Ever been to a conference when it seems like everyone is speaking over each other, trying to get the last word?
This is not only an indication of egos taking over and a lack of consideration for others; these are also indications of there being a lack of emotional intelligence. Interruptions erode trust.
When individuals are allowed to speak, and others listen without persistent interruptions, it is a good sign of EI.
It shows reciprocal respect between parties and is more likely to lead to a productive conclusion in meetings.
3. Being Flexible
Flexibility is a critical term in organizations today.
Building flexibility into how people function can be the difference between keeping the best workers and drifting out the door.
Emotionally intelligent leaders comprehend the changing needs of others and are ready to work with them rather than attempting to impose rigid restrictions on how people go about their work.
They do not expect everyone to work the hours they do, hold the same priorities, or live by precisely the same values.
Emotional Intelligence in Healthcare
1. Being Patient with Hurting Individuals
When in healthcare, it is expected that doctors and nurses will have to manage people in pain.
Emotional intelligence not only allows for better patient care but also for better self-care.
Pain often looks like anger. Recognizing this makes a nurse or doctor far less likely to take the combativeness personally, and easier to treat the patient well.
2. Acting as the Effective Leader
In healthcare, there is a necessity to have influential leaders, a trusting environment with a helpful team, critical thinking, and quality patient and family-centered care.
A higher emotional intelligence will allow healthcare professionals to respond and react better to patients.
Studies have shown a correlation between emotional intelligence and positive patient outcomes.
3. Responding Better to Stressful Situations
Multiple occasions in healthcare involve an urgent situation involving a life or death scenario. Doctors and nurses must check their own emotions.
Being in healthcare is a highly emotional career, and being aware of your feelings when they come up is key to effective self-care.
Interacting with patients can cause overwhelming joy or deep sadness, and these fluctuations can be utterly exhausting.
The ability to deal with these feelings, take breaks, and ask for help when you need it is another example of good emotional intelligence that nurses should practice.
Tips for Improving EI
Improving your emotional intelligence involves systematically training the way your brain and body process affective information.
The skills of recognizing, understanding, labeling, expressing, and regulating emotions are not fixed traits; they are highly malleable capacities that can be developed through deliberate practice.
Here are evidence-based, actionable ways to improve each of these five domains:
1. Recognizing Emotions
Recognizing emotions involves detecting signals both within yourself (intrapersonal) and in others (interpersonal).
Knowing when one is feeling anxious or angry can help process and communicate those feelings in a way that promotes healthy results.
Naming it early helps. Frequently check in with yourself to label complex emotional blends precisely (e.g., “I feel curious but a bit anxious”). This precision improves heart rate variability and positive emotion, turning a feeling into wisdom rather than suffering.
- Enhance Interoception: To recognize your own emotions, you must improve your interoception: your brain’s ability to sense and interpret internal physical signals from your body. You can train this by taking regular “interoceptive pauses” to scan your body for tension, posture, and autonomic arousal without immediately trying to change them.
- Avoid the “Hangry” Trap: Because the brain interprets homeostatic disruptions (like a drop in blood sugar) similarly to emotional distress, people frequently misinterpret physical needs, such as hunger or fatigue, as anger, anxiety, or irritability. Improving recognition means learning to accurately detect whether your body is sending an emotional signal or a basic physiological one.
- Track Nonverbal “Somatic Markers”: To recognize emotions in others, focus on their nonverbal cues rather than just their words. Pay attention to subtle shifts in vocal quality (e.g., a high-pitched, thin voice indicating restricted anxiety, or vocal perturbations that suggest a struggle to hold back tears). Observe posture, eye contact, and micromovements, recognizing that human nervous systems are constantly communicating safety or threat to one another below the level of conscious awareness.
2. Understanding Origins and Consequences
Understanding emotion requires operating like a detective to decode the “why” behind a feeling.
- Distinguish Primary vs. Secondary Emotions: A critical step in understanding is recognizing that the emotion you display (or see in others) is often a secondary emotion acting as a defense mechanism to mask a more vulnerable primary emotion. For example, a person might exhibit secondary, reactive anger because they are subconsciously trying to protect themselves from the primary, painful feeling of shame, fear, or abandonment. To understand an emotion, you must ask yourself: “What is the vulnerable feeling driving this reaction?”
- Identify the Unmet Need: Every primary emotion carries an implicit existential or interpersonal need. Sadness signals a need for comfort and connection; fear signals a need for safety; anger signals a need for boundary protection or justice. You can understand the origin of an emotion by asking, “What is at stake here, and what does this feeling need for it to be better?”.
- Analyze the Cognitive Appraisal: Emotions arise from how you appraise a situation. For instance, anger typically stems from a perceived injustice, while disappointment stems from unmet expectations. Understanding an emotion requires you to trace it back to the specific belief or interpretation you assigned to the triggering event.
3. Labeling with Precise and Accurate Words
Labeling emotions is far more than a vocabulary exercise; it is a profound regulatory tool.
- Practice Emotional Granularity: You must move beyond broad, unhelpful bins like “bad,” “stressed,” or “upset,” and strive for emotional granularity, the ability to use highly specific and nuanced words (Barrett, Gross, Christensen, & Benvenuto, 2001). Knowing the precise difference between feeling “anxious” (worrying about future uncertainty) and “envious” (comparing yourself socially) completely changes the coping strategy you should deploy. The distinction matters.
- Use “Affect Labeling” to Tame the Brain: The simple act of putting a precise word to a feeling (affect labeling) actually alters brain activity. Research by Lieberman and colleagues (2007) shows that accurately labeling a negative emotion reduces activity in the amygdala (the brain’s threat center) and increases activity in the prefrontal cortex, turning down physiological arousal and distress.
- Map Your Mood: If you struggle to find the right word, use an energy-pleasantness scale (like the Mood Meter). First, ask yourself if your physical energy is high or low. Second, ask if the feeling is pleasant or unpleasant. This places you in a specific quadrant (e.g., high energy/unpleasant), making it much easier to narrow down the label to words like “furious,” “panicked,” or “jittery”.
4. Expressing Appropriately Across Contexts
Expression must be strategically adapted to fit the cultural and relational environment you are in.
- Navigate Cultural Display Rules: Culture heavily dictates how emotions should be expressed. In Western, individualistic cultures, expressing assertive anger to defend one’s independent boundaries is often viewed as healthy. Conversely, in many East Asian or collectivistic cultures, expressing high-arousal negative emotions like anger is discouraged because it disrupts social harmony; instead, individuals may rely on more indirect communication or somatic (physical) expressions of distress. Improving expression requires multicultural humility and adapting your communication style to the context.
- Express the Primary Emotion, Not the Secondary One: In relationships, expressing secondary emotions (like lashing out in rage or withdrawing in cold silence) usually creates conflict. Expressing appropriately means sharing the underlying primary emotion. Saying “I feel hurt and lonely when you don’t ask about my day” is far more productive and invites connection, whereas yelling “You never care about anyone but yourself!” invites a defensive counterattack.
- Avoid “Co-Rumination”: When sharing emotions with friends, beware of simply venting. While venting can temporarily build a social bond, endlessly rehearsing a negative narrative without moving toward a solution (co-rumination) keeps you trapped in the negative emotion. Effective expression involves sharing the feeling to receive validation, and then actively working with the listener to broaden your perspective and problem-solve.
5. Regulating with Effective Strategies
Emotion regulation requires a flexible toolkit. When emotions hit, you must decide whether to use “bottom-up” physical strategies or “top-down” cognitive strategies.
- Use Bottom-Up (Physiological) Tools for High Arousal: When you are highly triggered, panicked, or enraged, your prefrontal cortex is impaired, making it nearly impossible to “think” your way out of the emotion. In these moments, you must regulate from the bottom up by changing your physiology. Highly effective tools include the physiological sigh (a double inhale through the nose followed by a long exhale through the mouth to rapidly offload carbon dioxide and lower heart rate), deliberate cold exposure to build resilience to adrenaline, or using physical touch and soothing environments.
- Use Top-Down (Cognitive) Tools for Reframing: Once your physical arousal is manageable, you can use your mind to shift the emotion. A powerful top-down tool is psychological distancing. Instead of immersing yourself in the pain, talk to yourself using your own name or the pronoun “you” (e.g., “How are you going to handle this situation, [Your Name]?”). This verbal shift tricks the brain into viewing the problem objectively, as if you are giving advice to a friend. Mental time travel is another tool: ask yourself how you will feel about this stressor a week, a month, or a year from now, which instantly broadens your perspective and diminishes the immediate sting.
- Create “If-Then” Plans (WOOP): To make regulation automatic, preemptively plan for your triggers. Use the framework of Wish, Outcome, Obstacle, and Plan. Identify the obstacle that usually dysregulates you, and formulate a strict “If-Then” protocol (e.g., “If I feel intense chatter and anxiety about a work project, Then I will step away from my desk for a five-minute walk in nature”).
- Beware the Self-Regulation Paradox: Regulation tools should help you feel and release emotions, not avoid them entirely (see below).
Cognitive and Attentional Shifting
Managing emotions often requires actively shifting one’s attention or adopting a new perspective to prevent a negative feeling from spiraling into total dysregulation.
- The “picture frame” distancing technique: If someone is being unfairly criticized or bullied by an angry family member at a dinner table, they might imagine a picture frame around the relative, observing them as if they are a character on a television show. This psychological distancing allows the person to remain curious about why the relative is so angry, rather than internalizing the hostility and bursting into tears or a fit of rage.
- Mental time travel: When confronted with an overwhelming problem, a person might use mental time travel to ask themselves, “How will I feel about this next week, next month, or next year?”. This instantly broadens their perspective, reminding them that the intensity of the emotion will naturally fade as time stretches on.
- Modifying attention: In the workplace, if a professional feels intensely frustrated by a colleague during a Zoom meeting, they might actively shift their gaze out the window to look at trees and birds instead of glaring at the colleague on the screen, thereby preventing themselves from saying something they will regret
Beware the Self-Regulation Paradox
While regulating your emotions is vital, you must avoid the “self-regulation paradox.”
This occurs when you constantly use tools like breathing exercises or journaling merely to avoid feeling uncomfortable emotions. The tools become a shield.
If you simply suppress or sidestep feelings like grief or anger without ever letting them complete their cycle in your body, they become trapped.
True emotional intelligence means using regulation tools to return to a “window of tolerance.” The feeling is then fully felt, processed, and released, rather than left to dictate your actions.
A core principle here is changing emotion with emotion. An unwanted or maladaptive emotion, like toxic shame, cannot easily be reasoned away. It can be transformed when you co-activate a stronger, opposing, adaptive emotion, such as self-compassion or assertive anger.
Why is Emotional Intelligence Critical?
Emotional Intelligence (EQ) is a core survival mechanism that facilitates rational decision-making and physiological health.
It involves the RULER skills: recognizing, understanding, labeling, expressing, and regulating emotions.
These skills constitute the ability to identify and manage feelings effectively in ourselves and others. That ability is trainable.
Far from being a “soft skill,” EQ allows the brain to process vast amounts of experiential data. This data guides our moral judgments and practical choices.
Without these emotional signals, the rational mind becomes overwhelmed by infinite possibilities
1. It is the Engine of Rational Decision-Making
Historically, society has pitted logic against emotion, but modern affective neuroscience reveals that rationality without feeling is virtually impossible.
Emotions act as “somatic markers,” intuitive gut feelings that guide our choices. They rarely lie.
Rather than being irrational, emotions function as a highly complex background processor.
They rapidly process huge amounts of experiential data to signal whether a situation feels right or wrong.
By steering you away from obviously bad choices and narrowing your options, emotions hand your rational mind a curated subset to work with.
This keeps the mind from becoming overwhelmed.
Consequently, emotional evaluations often form the accurate basis of our most profound moral, ethical, and practical judgments.
2. It Drives Peak Performance and Goal Attainment
In the realm of high achievement, emotional intelligence is a critical predictor of success. No one succeeds entirely alone.
Achieving “high hard goals” inevitably requires navigating the complexities of other people, who stand between you and your dreams.
Peak performers use EQ to build and maintain robust social support networks, which biologically alter how the brain perceives stress. Context matters.
When you encounter a massive obstacle alone, your brain registers it as a threat and sounds an alarm of anxiety.
However, if you have a highly functioning social network built through active listening and empathy, your brain appraises the same obstacle as a manageable challenge.
3. It Protects Physical and Mental Health
High emotional intelligence, specifically the skill of emotional granularity (labeling feelings with high precision), is directly correlated with measurable physical health benefits.
Accurately labeling your emotions improves respiratory sinus arrhythmia (RSA) and heart rate variability (HRV), key physiological markers of resilience, better sleep, and lower anxiety.
When individuals lack EQ and cannot differentiate between feeling anxious, sad, or angry, they often suffer from undifferentiated global distress that exacerbates psychological disorders. The cost is physical, not just emotional.
Furthermore, effectively regulating emotional intensity helps emotionally intelligent people prevent the chronic activation of the fight-or-flight response.
This saves their bodies from the intense wear-and-tear, or allostatic load, that leads to physical illness and burnout.
4. It Prevents Empathy from Becoming Destructive
While empathy is a beautiful trait, empathy without emotional intelligence can be dangerous and lead to compassion fatigue. Burnout often follows.
For example, caregivers or medical professionals who easily “catch” their patients’ negative emotions can quickly become paralyzed by despair if they do not know how to regulate themselves.
Emotional intelligence allows an individual to maintain self-other awareness: recognizing that they are getting lost in someone else’s feelings and deliberately pulling back to re-regulate.
It enables a person to shift from merely absorbing someone’s pain to offering compassionate, non-judgmental active listening that actively helps the other person gain perspective and feel better.
5. It Fosters Self-Restraint and Interpersonal Effectiveness
On a daily basis, emotional intelligence stops us from being hostages to our impulses. Emotional awareness is positively correlated with self-restraint and impulse control.
An intense feeling of anger might actually be a secondary reaction masking a deeper feeling of shame or fear.
Recognizing this lets an emotionally intelligent person stop themselves from lashing out.
This translates to better conflict resolution at home and in the workplace. That matters everywhere.
Emotionally intelligent individuals do not endlessly vent or “co-ruminate” on negative feelings without a strategy, as they know this merely rehearses and amplifies the distress.
Instead, they regulate their own reactions, accurately read the vocal tones and facial expressions of others, and co-regulate the people around them to foster psychological safety and trust.
Emotional Intelligence and Success
It is not the most intelligent people who are the most prosperous or the most fulfilled in life.
Many people are academically brilliant, yet socially incompetent and unsuccessful in their careers or intimate relationships. IQ alone is not enough.
Intellectual ability or intelligence quotient (IQ) is not enough on its own to achieve success in life.
Intelligence quotient can help someone get into university, but Emotional Intelligence (EI) helps that same person manage stress and emotions once they are there. The two work best together.
IQ and EI exist in tandem and are most influential when they build off one another.
Emotional intelligence also shapes leadership.
A leader who lacks emotional intelligence can drive down engagement and push up staff turnover.
Someone who is technically excellent at a job but cannot communicate or collaborate with a team will see those specialized skills go to waste.
Emotional intelligence pays off across every part of life. It helps people:
- Build relationships: succeed at work or school and achieve personal and career goals.
- Manage conflict: reduce group stress, defuse disagreements, and improve job satisfaction.
- Make better decisions: connect with inner feelings and turn purpose into action.
- Handle adversity: stay steady through confrontation, change, and other obstacles.
Practicing kindness and staying in touch with your emotions makes all of this easier.
History of Emotional Intelligence
Emotional intelligence has roots stretching back a century, long before the term itself existed:
- 1920s, social intelligence: psychologist Edward Thorndike described “social intelligence,” the ability to get along with other people.
- 1940s, non-intellective factors: David Wechsler argued that practical, non-intellective elements of intelligence shape how successful people are in life.
- 1950s, humanistic psychology: scholars such as Abraham Maslow turned attention to how people build emotional strength.
- Mid-1970s, multiple intelligences: Howard Gardner argued that intelligence was more than one single, broad capacity, a direct ancestor of EI. See multiple intelligences.
- 1985 to 1987, the label appears: Wayne Payne used the phrase “emotional intelligence” in a doctoral dissertation, and Keith Beasley introduced “emotional quotient” (EQ) in a Mensa Magazine article.
- 1990, the formal construct: psychologists John Mayer and Peter Salovey published their milestone article, Emotional Intelligence, in Imagination, Cognition, and Personality, defining EI as the capability to monitor one’s own and others’ feelings, discriminate among them, and use that knowledge to guide thinking and action.
- 1995, popularization: Daniel Goleman’s book Emotional Intelligence: Why It Can Matter More Than IQ brought the concept to a mass audience.
Salovey and Mayer also ran early research to test the idea. In one study, people who scored high on emotional clarity recovered faster after watching an upsetting film. In another, people skilled at reading others’ emotions responded more flexibly to changing social situations and built stronger support networks.
Critical Evaluation of Emotional Intelligence
Emotional intelligence is popular and genuinely useful, but it has drawn serious, well-founded criticism. Before looking at each point in detail, here is an overview:
- Definitional Incoherence: the mixed models fold in so many traits that EI risks becoming “everything but IQ.”
- Overlap With Personality: trait and self-report EI measures blend heavily into existing Big Five personality traits.
- Modest, Overclaimed Effects: genuine effect sizes are real but smaller than IQ’s, despite popular claims that EQ beats IQ.
- Measurement Disputes: ability tests and self-report questionnaires barely correlate, so different studies of “EI” often measure different things.
- Commercial Interests: several EI tests are proprietary products sold with paid certification, which can blur science and salesmanship.
- A Dark Side: the same skills that build rapport can be used to manipulate, deceive, or exploit others.
Definitional Incoherence
Organizational psychologist Edwin Locke leveled the sharpest attack on emotional intelligence in 2005, arguing the concept is not a form of intelligence at all. His case is simple.
The mixed models fold in so many disparate qualities, including self-awareness, motivation, optimism, assertiveness, impulse control, empathy, and social skill, that “emotional intelligence” stops meaning anything specific.
If a construct can include almost any positive trait, Locke argued, it explains nothing on its own. Even Mayer, whose own model is narrower, shares this worry.
The result is that “EI” in one study can mean a scored ability test, and in another an unstructured grab-bag of desirable dispositions, with no guarantee the two are related.
This is not just an academic quibble: it directly affects which claims about EQ a reader should trust.
Overlap With Personality and Incremental Validity
Trait emotional intelligence lives inside personality space by design, not by accident. Petrides and colleagues (2007) located trait EI among the lower-order facets of the Big Five, the dominant model of personality structure.
Self-report and mixed EI measures overlap substantially with Extraversion, low Neuroticism, Conscientiousness, and Agreeableness.
That overlap raises an uncomfortable question. If a “new” measure mostly retraces existing personality traits, does it add anything a personality test cannot already tell us?
The evidence is mixed. Self-report and mixed EI measures often add little once the Big Five are already accounted for.
Ability EI, tested with the MSCEIT rather than self-report, shows more defensible incremental validity, though still modest (Mayer, Roberts, & Barsade, 2008; O’Boyle et al., 2011).
In short, the case for EI as something genuinely new is strongest for the ability model and weakest for the versions closest to personality.
Popular Claims vs Modest Effect Sizes
Daniel Goleman’s bestseller made a bold promise: that emotional intelligence matters more than IQ for success. The data do not support it.
Mayer, Roberts, and Barsade’s (2008) review of the evidence found that EI’s measured effects on performance are real, but modest, and consistently smaller than those for cognitive ability. Popular writing still repeats Goleman’s stronger claim.
That gap between the science and the marketing is part of why EI attracts skepticism from psychologists who take the construct seriously. None of this means emotional intelligence is worthless: later meta-analyses, discussed below under Contemporary Research, confirm a real, if modest, predictive effect.
The honest summary is a real but modest effect, not the transformative “EQ beats IQ” story that made the topic famous.
Measurement Disputes: Ability vs Self-Report
Ask someone to rate their own EQ, then test their actual performance: the two scores barely agree. Joseph and Newman (2010) found the correlation between ability-based and self-report measures sits around r ≈ 0.2 or lower.
The gap is real. That is a strikingly weak relationship for two tools claiming to measure the same construct.
It means a person can believe they read emotions well while performing poorly when actually tested, or the reverse. Scoring itself is contested, too.
Ability tests like the MSCEIT grade “correct” emotional responses against expert judgment or the consensus of a large sample. Reasonable psychologists disagree about which scoring method is more valid.
Because studies pick one tradition or the other, findings described as being about “emotional intelligence” are not always about the same thing.
A reader comparing two EI studies should first check which kind of test each one used.
Contemporary Research
Recent research has moved from advocacy to synthesis. O’Boyle and colleagues (2011) pooled evidence across all three EI traditions: ability tests, self-report inventories, and mixed-model measures.
Each one predicted job performance with incremental validity beyond cognitive ability and personality. Mixed-model measures predicted best of the three.
They also overlap most with personality, though, so that finding partly restates the overlap problem above rather than resolving it.
Sánchez-Álvarez, Extremera, and Fernández-Berrocal’s (2016) meta-analysis turned to wellbeing and found a moderate, positive association between EI and subjective wellbeing across the accumulated literature. Neither meta-analysis settles the field’s central debate.
Whether emotional intelligence, properly measured, tells us anything about a person that intelligence and personality do not already capture, remains an open question (Mayer et al., 2008).

Why is emotional intelligence important in the workplace?
Researchers have indicated that emotional intelligence influences how excellently employees interact with their colleagues, and EI is also considered to play a role in how employees manage stress and conflict.
It also affects overall performance on the job. Other studies have connected emotional intelligence with job satisfaction.
Studies have shown that workers with higher scores on measures of EI also tend to be ranked higher on criteria of interpersonal functioning, leadership abilities, and stress management.
While standard intelligence was associated with leadership success, it alone was not enough. People who are prosperous at work are not just brilliant; they also have a high EI.
But emotional intelligence is not simply for CEOs and senior executives.
It is a quality that is essential at every level of a person’s career, from university students looking for internships to seasoned workers hoping to take on a leadership role.
Emotional intelligence is critical to success if one wants to succeed in the workplace and move up the career ladder.
Can emotional intelligence be taught?
As it turns out, the question whether emotional intelligence can be learned is not a straightforward one to answer.
Some psychologists and researchers claim that emotional intelligence is a skill that is not quickly learned or improved. Other psychologists and researchers, though, believe it can be improved with practice.
One key to improving EI is sustained practice – especially in high-stakes situations. Referring back to the above tips, one could read them and say those guidelines are pretty straightforward.
But, the challenging task is to do these practices in real-time and consistently. It takes practice to develop these skills. Then as you acquire them, you have to rehearse them under stress.
Can emotional intelligence be measured?
Several different assessments have arisen to gauge levels of emotional intelligence. These trials typically fall into one of two types: self-report tests and ability tests.
Self-report tests are the most abundant because they are the quickest to administer and score. Respondents respond to questions or statements on such tests by rating their behaviors.
For example, on a comment such as “I sense that I understand how others are feeling,” a test-taker might describe the statement as strongly agree, somewhat agree, somewhat disagree, or strongly disagree.
On the other hand, ability tests involve people responding to situations and assessing their skills. These tests often require people to demonstrate their abilities, which a third party rates.
If one is taking an emotional intelligence trial issued by a mental health professional, here are two measures that could be used: Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT) and the Emotional and Social Competency Inventory (ESCI).
What is the dark side of emotional intelligence?
The dark side of emotional intelligence is using one’s understanding of emotions manipulatively, to deceive, control, or exploit others.
High emotional intelligence can mask hidden agendas, enabling insincere charm or feigned empathy, potentially leading to deceitful or self-serving actions.
