What emotional intelligence actually is (and what it isn't)

By hmmm.me editorial team · Published April 19, 2026

Emotional intelligence is the psychology concept most likely to come up at a leadership retreat. It is also the concept most likely to be oversold.

The short version: there is something real at the core, and there is a lot of noise around it.

The origin

Psychologists John Mayer and Peter Salovey coined the term in 1990. They defined emotional intelligence as the ability to perceive emotions, use them to assist thinking, understand them, and regulate them. Their framing was careful and academic. A paper in a journal. A fairly narrow set of claims.

Then, in 1995, the journalist Daniel Goleman published a book called Emotional Intelligence: Why It Can Matter More Than IQ. The book made a much bigger argument: emotional intelligence predicts success in life — in relationships, in work, in leadership — at least as much as cognitive intelligence does, maybe more.

The book sold five million copies. Consultants turned it into workshops. HR departments turned it into hiring rubrics. The concept became a brand before the science could catch up.

What the research actually supports

Strip away the bestseller-era claims and what is left is still useful.

There are two main measurement approaches. Ability-based EI — the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT) — treats EI like an IQ-adjacent aptitude. It asks you to identify emotions in faces, resolve emotional scenarios, and so on. Answers can be scored against expert or consensus judgements. The scores correlate modestly with social outcomes and are relatively independent of IQ.

Mixed or trait EI — the approach Goleman popularised — is measured by self-report questionnaires and covers a broader mix of emotional skills, personality-adjacent traits, and social competencies. The scores predict outcomes too, but the predictions overlap heavily with what you would already get from Big Five personality data (especially Emotional Stability and Extraversion).

Short version: ability EI is a narrower construct that adds modest predictive power beyond IQ and personality. Trait EI is broader and largely overlaps with existing personality measures.

What got oversold

The claim that EI predicts career success “more than IQ” is not really supported by careful studies. When you control for general intelligence and Big Five traits, the additional predictive power of EI is modest — real, but much smaller than the book-jacket copy implied.

The claim that EI is a skill you can train up to any level through workshops is also thin. Short training programs show small effects. Longer practices — therapy, sustained self-reflection, significant life changes — show larger ones.

None of this means EI is fake. It means it is a normal-sized effect in a literature that got treated like a magic bullet.

What your score actually tells you

A 20-question self-report quiz is a sketch, not a measurement. It tells you how you describe your own emotional habits to yourself, filtered through whatever mood you are in while answering. That is useful for reflection, not for diagnosis.

The four dimensions we use — self-awareness, self-management, social awareness, relationship management — come from Goleman’s popular framing. If the quiz tells you your strongest area is social awareness, the honest reading is: “in the kinds of scenarios this quiz asks about, I report noticing other people’s emotional states more than I report, say, regulating my own.”

Translating that into a life strategy is up to you. The dimension labels are a starting point for “where do I pay attention?” and “where do I keep getting tripped up?” — nothing more.

One practical thing worth keeping

Of everything the EI literature covers, the single idea worth holding onto is this: noticing your emotional state before acting on it is a skill that improves with practice.

People who score high on self-awareness, behaviourally, are not unusually calm. They are unusually fast at clocking what they are feeling in a given moment. That gap between the feeling and the action is where every other piece of emotional skill gets installed.

You do not need a quiz to work on that. But the quiz is a decent snapshot of where you currently are. If your self-awareness score is low and your relationship management score is high, that is a recognisable pattern — someone who looks after other people’s feelings well while staying a bit foggy about their own.
