Emotional intelligence has had a strange twenty years. It arrived as a serious research construct, was absorbed by corporate training, and came out the other side as a phrase that means almost nothing — usually deployed to suggest that somebody else should be calmer.
Underneath the noise sits a real question: can it actually be taught, or is it a temperament you either have or you don't?
The evidence now points fairly clearly one way.
What the research found
A meta-analysis of workplace emotional-competency training pooled interventions across a wide range of professions and asked whether they worked. They did. Emotional competencies improved with training — and, notably, the effect did not depend much on which profession people came from, or on whether the programme was labelled emotional intelligence, empathy, or emotion regulation.
A separate 2025 systematic review looked specifically at nurses and nursing students — a group under sustained emotional load — and found training improved emotional intelligence, resilience, stress and communication.
That is a more interesting result than it first appears, for an unglamorous reason: it suggests the mechanism is general. Something that transfers across professions and across programme labels is probably not a niche technique. It is more likely a small set of underlying capacities — noticing what you feel, naming it accurately, and having more than one response available — that respond to deliberate practice the way most capacities do.
What the research does not say
This is the point at which the field usually overreaches, so it is worth being careful.
The reviewers themselves flag high heterogeneity and low methodological quality across the studies included, and call for more randomised controlled trials. That is not a small footnote. It means the direction of the finding is reasonably solid — training helps — while the size of the effect is not yet trustworthy.
So: emotional intelligence can be trained. How much, for how long, and whether it holds under real pressure rather than on a questionnaire two weeks later — those remain open.
Why the distinction changes the approach
If emotional intelligence were temperament, the sensible response would be self-knowledge: learn your wiring, arrange your life around it, stop expecting to be different.
If it is trainable, the sensible response is another thing entirely. It becomes a skill with a practice, which means the ordinary rules of skill apply. Skills improve with feedback rather than exposure. They improve faster with difficulty than with comfort. And they degrade without use.
That reframing matters for anyone who has quietly concluded they are “just not an emotional person” or “too reactive”. Under a temperament model, that is a fact about you. Under a skill model, it is a description of your current level.
Two better self-checks
The standard question — how emotionally intelligent am I? — is not very useful, because almost everyone places themselves in the upper half.
Two narrower ones, borrowed from how the research actually measures this.
When you were last upset, how long did it take you to name what the feeling was? Not the story about who caused it. The feeling itself.
And when you were last upset, how many responses were available to you? Most people who describe themselves as reactive do not have a feeling problem. They have a repertoire problem — one response, arriving fast.
Neither is a test. They are simply the two places the research suggests movement happens.
What did you feel last week that you never named?
