Emotional Intelligence in Leadership: What the Evidence Supports
March 3, 2025 · Education · 7 min read
Emotional intelligence is often presented as a leadership superpower. The evidence supports a more useful conclusion: leaders benefit from being able to recognise emotions, regulate their own responses, understand other people’s perspectives and manage relationships, but emotional intelligence is not a substitute for judgement, technical competence, ethics or organisational systems.
A 2026 systematic review and correlational meta-analysis found positive associations between emotional intelligence, transformational leadership and team effectiveness. The authors also reported substantial conceptual and methodological heterogeneity and noted that much of the evidence is correlational rather than proof that increasing an EI score will automatically improve team performance.
What emotional intelligence means
There is more than one model of emotional intelligence, and different assessments do not necessarily measure exactly the same construct.
In practical leadership terms, EI discussions commonly include capabilities such as:
- recognising your own emotional state;
- regulating impulsive reactions;
- recognising emotional cues in others;
- understanding how relationships affect decisions;
- communicating in a way that fits the situation;
- handling disagreement without unnecessary escalation.
These are useful leadership behaviours even if an organisation never administers a formal EI assessment.
Self-awareness is useful when it changes behaviour
Knowing that you become defensive under challenge is only useful if it helps you respond differently.
Leaders can improve self-awareness by examining:
- which situations trigger strong reactions;
- how their tone changes under pressure;
- which feedback they resist;
- whether others experience them differently from how they see themselves;
- which assumptions shape their decisions.
Reflection should lead to a behavioural adjustment, not only a personality label.
Emotional regulation does not mean suppressing emotion
Regulation means managing how emotions influence action.
A leader can be frustrated and still choose not to humiliate an employee. A leader can be anxious about a project and still communicate priorities clearly. A leader can be disappointed and still separate the performance problem from the person’s worth.
Useful techniques include:
- pausing before responding;
- checking the evidence behind an interpretation;
- asking a question before making an accusation;
- delaying a difficult conversation until the leader can conduct it constructively;
- preparing the purpose and facts before high-stakes conversations.
Empathy is perspective taking, not automatic agreement
A leader can understand why an employee is upset without agreeing with every conclusion or request.
Practical empathy involves:
- listening without immediately preparing a rebuttal;
- checking what the other person means;
- recognising constraints the leader may not see;
- considering how a decision will be experienced;
- explaining a decision respectfully when the answer is still no.
Empathy without boundaries can create inconsistency. Boundaries without empathy can create unnecessary distrust.
Emotional intelligence matters in feedback
Feedback can trigger defensiveness for both the person giving it and the person receiving it.
A leader with strong interpersonal awareness can:
- describe observable behaviour;
- explain impact;
- listen to context;
- keep the conversation focused on improvement;
- avoid turning a performance issue into a character judgement.
This does not mean avoiding difficult feedback. It means delivering it in a way that preserves clarity and dignity.
It also matters in conflict, but conflict still needs structure
Recognising emotion can help a leader notice when a disagreement is becoming personal or unsafe. But EI alone does not resolve disputes.
Leaders still need:
- clear behavioural standards;
- fact finding;
- role clarity;
- appropriate escalation;
- HR or legal processes where necessary.
See MATSH’s Conflict Management at Work guide for the distinction between ordinary disagreement and issues such as bullying, harassment or discrimination.
Emotional intelligence can support decision-making by improving the inputs
Emotions contain information, but they are not infallible evidence.
A leader might notice that a team is unusually anxious about a deadline. That signal can prompt useful questions:
- Is the scope unclear?
- Is the deadline unrealistic?
- Is there a hidden risk?
- Has the team lost confidence in the plan?
The leader should then investigate rather than assuming the emotional signal itself proves the answer.
EI should not become a reason to ignore structural problems
An organisation can overuse emotional-intelligence language by framing every difficulty as an individual’s inability to regulate emotions.
Sometimes the real issue is:
- excessive workload;
- unclear authority;
- poor process design;
- inconsistent leadership;
- unfair treatment;
- unsafe behaviour;
- insufficient resources.
Teaching employees to cope better does not fix a system that needs redesign.
Do not use EI scores as a universal leadership ranking
Different EI instruments use self-report, ability tests, observer ratings or mixed models. Scores can therefore mean different things.
Before using an assessment for selection or promotion, organisations should ask:
- What construct does it measure?
- Is it valid for the intended use?
- Is it reliable?
- Has it been tested in a relevant population?
- Could it create adverse or unfair outcomes?
- Should it be only one source of evidence rather than a gatekeeping score?
Leadership decisions should not rest on a single personality or EI test.
Emotional intelligence and transformational leadership are related, not identical
The 2026 meta-analysis found a strong positive correlation between EI and transformational leadership in the studies it included. That does not mean the concepts are interchangeable.
Transformational leadership concerns behaviours such as inspiring direction, intellectual stimulation and individual consideration. Emotional intelligence concerns emotional information and regulation. A leader may use emotional skill in many leadership styles.
Team effectiveness is influenced by more than the leader’s EI
Teams are also affected by:
- goals;
- skills;
- resources;
- trust;
- psychological safety;
- decision rights;
- information sharing;
- workload;
- incentives;
- team design.
See MATSH’s How to Build Effective Teams guide for the wider evidence base.
Can emotional intelligence be developed?
Specific behaviours related to EI can be practised.
Useful development methods include:
- behavioural feedback;
- coaching;
- reflection after difficult situations;
- role-play;
- practice with real conversations;
- 360-degree feedback where appropriately designed;
- structured listening and questioning practice.
Improvement should be judged by behaviour, not only by whether a training participant reports feeling more emotionally intelligent.
A practical EI development routine for managers
Before a difficult conversation
- What outcome do I need?
- What facts do I have?
- What am I assuming?
- What emotion am I bringing into the conversation?
- How might the other person see the issue?
During the conversation
- Describe the issue clearly.
- Ask for the other person’s perspective.
- Listen for both facts and concerns.
- Check your interpretation.
- Agree the required next step.
After the conversation
- Did I achieve clarity?
- Did I react to anything unnecessarily?
- What did I learn that changed my understanding?
- What should I do differently next time?
Use EI alongside managerial discipline
Good leadership requires both relational skill and operating discipline.
A leader may be empathic and still need to:
- set a deadline;
- make an unpopular decision;
- address poor performance;
- allocate scarce resources;
- say no;
- enforce a policy.
Emotional intelligence should improve how the leader handles those responsibilities, not remove them.
Emotional intelligence in multicultural teams
Emotional cues and communication norms vary between individuals and cultures. Leaders should therefore avoid assuming that one behaviour always signals one emotion.
Useful habits include:
- asking rather than guessing;
- checking meaning when communication is ambiguous;
- making team norms explicit;
- learning individual preferences;
- avoiding stereotypes about how a nationality “shows emotion”.
Measure development with behavioural evidence
If a leadership programme includes EI-related development, possible measures include:
- quality of feedback conversations;
- 360-degree behavioural ratings;
- manager observation;
- conflict escalation patterns;
- employee experience of manager communication;
- specific leadership behaviours agreed in the development plan.
Do not claim that an EI course increased organisational performance by a fixed percentage without an evaluation design that supports that conclusion.
Frequently asked questions
Is emotional intelligence proven to make leaders more effective?
Current meta-analytic evidence finds positive associations between emotional intelligence, transformational leadership and team effectiveness. Much of the evidence is correlational and heterogeneous, so it does not justify a universal causal percentage.
What are the main emotional intelligence skills for leaders?
Useful practical capabilities include self-awareness, emotional regulation, perspective taking, listening, relationship management and responding constructively under pressure.
Is empathy the same as agreeing with employees?
No. Empathy means trying to understand another person’s perspective. A leader can understand a concern while still making a different decision or holding a boundary.
Can emotional intelligence be trained?
Related behaviours can be practised through feedback, coaching, reflection and real conversations. Improvement should be evaluated behaviourally rather than assumed from course completion.
Should companies hire leaders based on EI tests?
A single EI test should not be treated as a universal leadership verdict. Any assessment used for selection should be valid for the purpose and combined with broader evidence of job capability.
