Emotional intelligence training has research support. Reviews of adult training and workplace interventions have found average improvements on the emotional intelligence or related competency measures used in the studies. That is a useful reason to take training seriously.
The next question is what improved. A higher self-rating, better performance on an emotional task and a change in everyday communication provide different evidence. None automatically establishes the others, and an average training effect cannot tell you how much you personally will benefit.
To evaluate a program, connect its claim to its actual outcome measure, comparison and follow-up.
Start with the outcome behind “it works”
A training evaluation can investigate several different questions:
If you want to turn reading into self-measurement, continue into an assessment.
Evidence
What it can help establish
What remains to be checked
Self-report questionnaire
How participants describe their emotional tendencies or skills
Whether behavior or task performance changed
Emotional performance task
Performance on specified materials under a scoring rule
Transfer to unfamiliar situations and everyday interactions
Ratings by colleagues or other observers
What others noticed within their observation opportunities
Rater expectations, context and coverage
Real-world behavior or outcomes
What happened in a particular setting
Whether training caused the change and whether it generalizes
Suppose someone finishes a course believing they understand other people better. That is a self-perception outcome. Recognizing emotions more accurately on an unfamiliar task would provide different evidence. Checking an interpretation with a colleague and accepting a correction would provide information about an actual interaction.
These observations can complement each other. Treating them as interchangeable makes a training claim stronger than its evidence.
Self-report also has a useful role: it can capture experiences an observer cannot directly see. But learning may change the standard a person uses. Someone who previously equated staying silent with managing emotion may begin to notice that silence sometimes conceals an unresolved problem. A flat or lower self-rating would not, by itself, establish that nothing was learned. A higher rating would not establish improved ability either.
Mattingly and Kraiger’s 2019 meta-analysis identified 58 published and unpublished studies using before-and-after or treatment–control designs. Its abstract reports a moderate positive effect of formal training on emotional intelligence scores. This supports the possibility of improvement on EI measures; it does not validate every program using the EI label. 2019 training meta-analysis
A workplace review published in 2024 examined employed adults. It synthesized before-and-after changes across 50 studies and separately analyzed 27 studies with control groups. Both analyses produced positive overall results. Its scope included emotional intelligence, empathy and emotion regulation under the umbrella of emotional competencies. Those are related areas, not one interchangeable EQ score. The review’s literature search was last updated in November 2022. 2024 workplace review
The interventions used methods including instruction, discussion, role-play, practice and feedback. Evidence about those programs does not establish that any single ingredient works on its own, or that another course using similar activities will produce the same result.
Measurement matters here: the workplace review reports that most studies used self-report, while only seven of the 50 used ability tests. The authors also discuss differences among self-report, observer ratings and performance measures. The clearest interpretation stays with the outcomes actually assessed. Measurement and limitations discussion
Population matters too. A 2025 review concerns nurses and nursing students. It contributes evidence for those groups, but cannot directly stand for every occupation or adult setting. A newer publication does not necessarily have a broader application. 2025 nursing review abstract
An average effect is not your percentage improvement
Meta-analyses often use standardized effect sizes to combine results from different measures. These express a difference relative to the spread of scores, rather than putting everyone on a universal scale of emotional development.
A “moderate effect” therefore does not mean a 50% improvement or a 50% success rate. It describes an average difference in the synthesized research. It cannot tell you that every participant improved, how much a particular person changed or whether the change mattered for that person’s goals.
The 2024 review found substantial variation among studies and signs of possible publication bias. Available published findings may not fully represent all training that has been evaluated. The authors also identify low methodological quality as a major limitation: many studies had serious or critical risk of bias, and most lacked random allocation or adequate control of confounding. Sensitivity analyses still produced positive estimates, but their size changed with the analysis and did not remove these methodological limitations. The evidence supports trainability while leaving uncertainty about the precise size and conditions of benefit. Results and sensitivity analyses
The review did not detect significant differences between occupational groups. That is not proof that every profession, participant or course benefits equally. Failing to detect a difference and demonstrating equivalence are different conclusions.
Do gains last, and do they transfer?
An assessment near the end of training tells you about that period. Retention requires later observation. Transfer requires evidence that learning can be used beyond the practiced materials or classroom.
Among studies providing relevant follow-up, the workplace review found evidence of improvement beyond three months. This does not mean all 50 studies followed participants for the same period, or that gains are permanent. The authors call for more high-quality studies with follow-up. Follow-up findings and recommendations
Improved competency scores also do not automatically establish higher pay, better job performance or better relationships. The review says the available evidence is not extensive enough to provide a comprehensive account of training participation and outcomes such as job performance, work stress and sick days. A claim about one of those outcomes needs evidence directly addressing it.
For personal practice, a goal such as “check what the other person is concerned about before defending my position” is easier to examine than “become a high-EQ person.” Look for a suitable opportunity, the action you took, the feedback and the practical cost. If no relevant interaction occurred, the outcome remains unknown.
Look at the comparison, not just the testimonial
A before-and-after increase is a useful observation. On its own, it cannot separate training from other explanations, including familiarity with the assessment, expectations, recent events or a changed understanding of the questions.
A comparison group assessed over the same period helps investigate what might have happened without the program. Random allocation helps reduce systematic differences between groups. An alternative activity can help examine whether attention or participation in a group explains some of the change. These designs answer different questions; “we collected data” does not tell you which question was tested.
Also check who was included in the reported result. Were outcomes available only for completers? Were people who left the program accounted for? Was assessment immediate or delayed? Did it involve practiced tasks or a new setting?
Who evaluates the program is relevant as well. The 2024 review discloses that some authors offer small-scale emotional competency training through a university-based center. Such involvement does not automatically invalidate findings. It makes transparent methods and independent evaluation useful context when judging the evidence.
Missing information limits the claim you can accept. It does not establish that the course is ineffective.
A worked example: “25% better EQ in four weeks”
The following program, person and numbers are original synthetic examples. They are not a review of a real course or results from a training study.
Jamie wants to stop rushing into explanations during project disagreements and become more accurate at checking the other person’s concern. A course advertises “25% better EQ in four weeks, improving team communication.”
Jamie requests the evaluation. Twenty-four people enrolled. Eighteen completed both administrations of the same 0–100 self-report questionnaire. Their mean increased from 60 to 75. The report includes no control group, no outcomes for the other six participants and no later observation.
First, Jamie checks the arithmetic. The increase is 15 points, and 15 divided by 60 is 25%. That calculation describes a relative change in the completers’ questionnaire mean. It does not mean each person improved by 25%, or that their real-world communication ability increased by that amount. The report also has not established that zero on the questionnaire means a complete absence of emotional ability, so it has not justified interpreting the percentage as an increase in ability.
Second, Jamie identifies the supported finding: the mean self-report score among the 18 completers increased on that questionnaire. The result alone does not establish that the course caused the increase. Nor can Jamie assume the six missing participants failed to improve—or count them as successes.
Third, Jamie returns to the goal. The relevant question is whether, in a new disagreement, they can check a concern before defending their position. They ask what skill the course practices, whether the evaluation assesses that skill, what feedback is available and how long any change was observed.
Suppose the provider explains that the course includes discussion and role-play, but has no further outcome evidence. Jamie can recognize possible learning value while concluding that the advertised improvement claim exceeds the supplied evidence. Because the course requires a substantial time commitment and Jamie’s choice depends on evidence of effectiveness, they decide not to enroll on that basis.
This decision concerns whether the available evidence supports accepting the promise. It does not prove the program ineffective. Better evidence matched to the program, population and goal could change the decision.
What to look for when choosing or trying training
Begin with a specific goal and look for content, practice and feedback that address it. Finding role-play or discussion in a research review does not make every program using those methods equivalent. Duration alone is not a measure of quality, and these reviews do not establish one optimal number of days or hours for everyone.
During practice, separate what you learned from what you did and what happened afterward. More accurate understanding, a clearer request or a corrected misunderstanding can be meaningful targets. Permanent calm, no disagreements and universal approval are poor universal success criteria.
The existing emotional awareness and communication practice guide provides complete synthetic scenes involving criticism, an extra request and a misunderstanding. It includes observable actions, failure adjustments and boundaries. These are editorial practice suggestions, rather than validated training protocols.
Where FermatMind EQ-60 fits
EQ-60 organizes 60 self-descriptions across Self-Awareness, Emotion Regulation, Empathy and Relationship Management. It can help generate reflection questions. It does not currently serve as a training-effectiveness measure: a score difference alone cannot establish improved ability, an effective course or a successful exercise.
If you have used it, the EQ-60 results guide explains indicators, versions, reference status and response conditions. Read those alongside relevant interactions. Whether to continue training should depend on evidence matched to your goal, useful feedback and acceptable costs, rather than one higher self-rating.
