Two numbers get repeated in almost every article about emotional intelligence at work: 90 percent of top performers have it, and it accounts for 58 percent of job success. Both trace back to the same source, a company that sells emotional intelligence tests, and neither has been published in a peer-reviewed journal. That does not mean emotional intelligence is unimportant. It means the case for it is usually made badly, with numbers that will not survive a second look.
There is a better case, built on research that has actually been through peer review, and it is more interesting than the marketing version because it comes with a real caveat.
What is emotional intelligence?
Emotional intelligence, often shortened to EQ or EI, is the capacity to recognize emotions in yourself and others and to use that information to guide thought and behavior. The term originates with psychologists Peter Salovey and John Mayer, who introduced it academically in 1990 as an ability, closer to a cognitive skill that can be tested than a personality trait that can be surveyed. Daniel Goleman popularized the concept for a general audience in 1995 and is the source of the five-part model most workplace training still uses.
That origin matters more than it looks, because it splits emotional intelligence research into two camps that measure different things and get confused constantly.
Ability EI versus trait EI: the distinction nobody explains
Salovey and Mayer’s original version is ability EI, measured with performance tests where there is a right and wrong answer, similar to an IQ test but for emotional reasoning. Almost nothing sold as an EQ assessment in the corporate training market uses this method, because it is expensive to administer and score.
What gets sold instead is trait EI, sometimes called mixed EI: a self-report questionnaire where you rate your own emotional skills. It is fast, cheap and popular, and it is also the version behind the 90 percent and 58 percent statistics. The problem, established by Joseph, Jin, Newman and O’Boyle in a 2015 meta-analysis in the Journal of Applied Psychology, is that self-report EI overlaps heavily with a set of already well-known traits: self-efficacy, conscientiousness, emotional stability, extraversion and general mental ability, correlated at .79. Once those are statistically controlled for, self-report EI’s link to supervisor-rated job performance falls to essentially nothing.
Read plainly: if a statistic about EQ and performance came from a self-report test, it is probably measuring confidence and personality wearing an EQ label. That includes the TalentSmart figures, drawn from the company’s own proprietary assessment database and popularized in Bradberry and Greaves’ 2009 book, never published for independent peer review.
What the more careful research actually shows
None of this means emotional intelligence does not matter. It means the honest version of the claim is smaller and more specific than the marketing version.
Zaghmout (York St John University, 2024) surveyed and interviewed 150 managers and staff across 30 UK companies, comparing self-rated emotional intelligence scores against firm-level metrics including revenue growth and profitability, controlling for age, gender, sector and company size. The finding: a 10 percent increase in a manager’s emotional intelligence score was associated with a 7 percent increase in overall business performance. That is a real, controlled, if modest and self-report-based, finding, and it is a fraction of the size implied by figures like “34 percent higher profit margin,” which do not trace to any locatable published source.
The honest summary sits between two extremes. Emotional intelligence is not the single biggest driver of workplace success, as vendor marketing claims. It also is not nothing, as a purely skeptical reading of the self-report literature might suggest. It is one real, moderate factor, best measured through behavior rather than a questionnaire score.
The five components of emotional intelligence
Goleman’s model remains the most widely used framework, even though it was built as a popularization rather than an empirically derived taxonomy.
- Self-awareness. Recognizing your own emotional states and how they shape your thinking and behavior.
- Self-regulation. Managing emotional responses rather than being controlled by them, particularly under pressure.
- Motivation. A drive toward goals that is not purely external, status or compensation.
- Empathy. Reading and responding appropriately to what others are feeling.
- Social skills. Building relationships, resolving conflict, and influencing others constructively.
These five categories are a useful vocabulary for talking about the skill. They are not, on their own, a training curriculum, which is a distinction that matters for anyone about to commission a workshop.
How EQ shows up in day-to-day work
The abstract categories above translate into a small number of observable behaviors. Communication that adjusts to the listener rather than repeating the same delivery regardless of audience. Conflict that gets addressed directly instead of avoided until it escalates. And composure under pressure that holds up in the actual high-stakes moment, not just in a calm debrief afterward.
Each of those is something a manager can actually observe, which is the more useful measurement than a self-report score. Our detailed breakdown of workplace communication protocols covers the communication piece specifically, including why structured protocols outperform generic listening advice.
Is emotional intelligence a future-of-work skill?
It is often cited as one, but the exact claim is usually overstated. The World Economic Forum’s Future of Jobs Report 2025 does not list “emotional intelligence” by that name in its top 10 core skills. The closest entry is “empathy and active listening,” which ranks seventh, alongside analytical thinking, resilience, leadership and social influence, and creative thinking above it. That is a real and specific finding, and it is a narrower, more defensible claim than “EQ is one of the top skills for the future,” which is the version most articles print instead.
Building it: where the real work happens
Reading about emotional intelligence changes very little on its own. What moves the needle is converting each component into a specific, practiced behavior with a manager checking in on it, not a workshop that ends when the slides do.
We cover that process in full, including a 12-week structured plan with weekly checkpoints, in our guide to building emotional intelligence in the workplace. This page is the why. That one is the how.
If emotional intelligence development sits inside a broader leadership track, keep it on the same record as the rest of that program rather than tracking it separately. Leadership development programs that fragment across three different tools tend to lose the observation data that actually proves anything happened.

Where to start
Skip the assessment and start with observation. Pick one behavior from the list above, communication that adapts to the audience, conflict addressed directly, composure under real pressure, and ask a colleague whether they see it in you. That single data point is worth more than a percentile score on a self-report test.
