Emotional Intelligence: Is It More Important than your IQ?
Huffingtonpost

Is emotional intelligence more important than IQ? The honest answer is that they do different jobs. IQ, or general mental ability, remains one of the stronger single predictors of how well people learn and perform in complex work. Emotional intelligence (often shortened to EI or EQ) describes how well you notice, understand and manage emotions, your own and other people’s. Research suggests it adds something useful, especially in decisions, relationships and handling stress, but the bold claim that it matters “twice as much” as IQ is not supported by the evidence. The most useful way to see them is as partners rather than rivals.

This guide explains what emotional intelligence is, what one well-known experiment found about emotions and decision making, what the wider research says, and how you can build these skills in everyday life.

What emotional intelligence actually means

The idea was set out by psychologists Peter Salovey and John Mayer in 1990 and became famous through Daniel Goleman’s 1995 bestseller Emotional Intelligence. Salovey and Mayer’s “ability model” describes four linked skills:

  • Perceiving emotions: reading faces, voices and your own bodily signals accurately.
  • Using emotions: letting moods support thinking, for example using a calm, curious state for creative work.
  • Understanding emotions: knowing what causes feelings, how they blend and how they change over time.
  • Managing emotions: regulating your own reactions and responding helpfully to other people’s.

Other researchers define EI differently. Goleman’s popular “mixed model” bundles in motivation, empathy and social skill, while the “trait” approach treats EI as a set of self-perceptions measured by questionnaire. These differences matter, because a lot of confusion about EI comes from people using one word for several different things.

The experiment: anxiety that has nothing to do with the decision

A study by Jeremy Yip and Stéphane Côté, published in Psychological Science in January 2013, looked at one specific part of emotional intelligence: understanding where your feelings come from. Yip was then at the Wharton School of the University of Pennsylvania and Côté at the University of Toronto’s Rotman School of Management. The study is sometimes misreported online as Yale research, but neither author was based there.

The researchers were interested in “incidental” anxiety, worry that comes from something unrelated to the choice in front of you. Imagine you are nervous about a presentation tomorrow, and today you need to decide whether to accept a reasonable investment or a new opportunity. The worry belongs to the presentation, yet it can still make you play safe.

In the first experiment, incidental anxiety made people more cautious, but mainly those who scored lower on emotion-understanding ability. People who understood emotions well seemed to recognise that the worry was irrelevant and set it aside. In the second experiment, the gap disappeared when the researchers simply told participants where their anxiety came from. Once people knew the true source of the feeling, it stopped steering their decision.

In the authors’ words, emotion-understanding ability “guards against the biasing effects of incidental anxiety.” Côté also stressed that emotionally intelligent people do not remove emotion from decisions altogether. As he told reporters, “they remove emotions that have nothing to do with the decision.”

EQ versus IQ: what the wider research says

One experiment cannot settle a big question, so it helps to look at the broader evidence.

  • EI does relate to job performance. A 2011 meta-analysis by O’Boyle and colleagues found moderate correlations (roughly 0.24 to 0.30) between EI and job performance across the main models.
  • But some of that overlaps with IQ and personality. Dana Joseph and Daniel Newman’s 2010 meta-analysis found that ability-based EI added little once intelligence and the Big Five personality traits were taken into account, though self-report measures kept some predictive power.
  • In education, EI seems to add something. A 2020 meta-analysis led by Carolyn MacCann found that students with higher EI tended to have better grades, even after controlling for intelligence and personality.
  • Measurement is still debated. Critics point out that emotional situations often have no single correct answer, which makes EI harder to test than reasoning or vocabulary.

So EI is not a magic ingredient that replaces intelligence, and IQ is not the whole story either. What EI seems to do best is help people use the abilities they already have, especially under pressure, in relationships and in jobs that depend on working with others.

Where each one tends to make the bigger difference

A practical way to think about the two is to ask what a situation demands. Learning a new technical subject, analysing data, diagnosing a fault or following a complex argument lean heavily on reasoning ability. Leading a team through a tense reorganisation, calming an upset customer, negotiating a pay rise or keeping a long marriage healthy lean much more on reading and managing emotions.

Most real jobs and most of daily life mix both. A gifted surgeon still has to explain risks to a frightened patient. A warm, intuitive manager still has to understand the budget. That is why researchers increasingly stop asking which one “wins” and look instead at how they work together. A person with solid reasoning who also notices when stress, pride or fear is colouring their judgement has a real advantage over someone who relies on either skill alone.

It is also worth remembering that neither score is destiny. Habits, health, opportunities, the people around you and simple persistence all shape outcomes, often more than any single test can capture.

How low emotional awareness plays out in real life

Consider someone bright and successful whose job brings months of steady stress. If they never stop to ask what they are feeling and why, the stress does not stay at work. It can surface as irritability with a partner, short temper with children, poor sleep or reaching for alcohol to switch off. The original problem, an overloaded job, gets buried under new ones.

Someone with stronger emotional awareness might notice the same pressure earlier and name it: “I’m tense because of the project deadline, not because of anything at home.” That small act of labelling makes it easier to choose a better response, such as talking it through with a friend, going for a walk, or speaking to a manager about workload. Psychologists sometimes call this ability to step back and watch your own reactions an “observing ego”.

None of this means people with lower EI are doomed to bad choices, or that difficulties such as addiction or relationship breakdown have a single cause. Life is more complicated than that. But understanding your inner state is one of the few tools that helps in almost every situation.

Common myths about emotional intelligence

  • “EQ matters more than IQ for success.” This line became popular after Goleman’s book, but research does not support a fixed ranking. Both matter, in different ways and different jobs.
  • “Emotionally intelligent people are always calm and nice.” Being skilled with emotions can mean expressing anger clearly, saying no, or staying with discomfort rather than smoothing it over.
  • “Good decisions are emotion-free.” Emotions carry useful information about risk, values and other people. The Yip and Côté study suggests the skill is in sorting relevant feelings from irrelevant ones.
  • “You either have it or you don’t.” Researchers disagree on how much EI can be trained, but several studies report benefits from training. In one 2019 field study, Australian special forces soldiers who received EI training showed lower stress-hormone levels during simulated stress than a comparison group.

Practical ways to build emotional intelligence

You do not need a test score to start. Small, regular habits make the biggest difference:

  • Name the feeling. Go beyond “fine” or “stressed”. Are you disappointed, embarrassed, overwhelmed, restless? A precise word makes the feeling easier to work with.
  • Ask where it came from. Before an important choice, check whether your mood belongs to this decision or to something else that happened today.
  • Delay when the feeling is unrelated. If you notice strong emotion from another source, and the decision can wait, give it a few hours or sleep on it.
  • Listen for the emotion behind other people’s words. A colleague’s sharp email may be about pressure, not about you.
  • Use healthy outlets. Exercise, time outdoors, talking to someone you trust and writing things down all help feelings move rather than build up.
  • Review the day. A two-minute note each evening, listing one moment you felt strongly, what triggered it and how you responded, quickly reveals patterns you would otherwise miss.
  • Ask for honest feedback. People close to you often see your emotional habits more clearly than you do. Ask one trusted friend or colleague how you come across when you are under pressure, and listen without arguing.

Progress is gradual. Most people notice the change first in small moments: catching a sharp reply before it leaves their mouth, or realising halfway through a bad mood that it started with something unrelated hours earlier.

If stress, anxiety or low mood keep getting in the way of daily life, talk to a doctor or a qualified mental health professional. Emotional skills are valuable, but they are not a substitute for proper support when you need it.

The bottom line

IQ helps you solve problems; emotional intelligence helps you notice which problem you are really dealing with and stay steady while you solve it. Neither is a guarantee of a good life. Together, plus effort, good relationships and a bit of luck, they make it far more likely. If you want one habit to take from this article, let it be the simplest: before a big decision, ask yourself what you are feeling and whether it belongs here.
