Is anger a sign of low intelligence? The idea pops up regularly on social media, usually alongside a clip of someone losing their temper and a caption suggesting that clever people stay calm. It is a neat story, but psychology paints a more interesting and more forgiving picture.
Anger is one of the most common emotions people feel. The question is not whether you get angry, but what you do with that feeling, and how it shapes the way you think and decide in the moment.
This piece looks at what the research says about anger and intelligence, why angry people may feel smarter than they are, and how to handle anger in a way that works for you rather than against you. It also explains when it may be time to ask for support.
Is anger a sign of low intelligence?
There is no good evidence that feeling anger reflects low intelligence. Intelligence is usually understood as the capacity to reason, learn, and solve problems, as explained in our guide to intelligence and the different quotients. Anger is an emotion, and people across the full range of ability experience it.
The NHS describes anger as something most people feel from time to time. It often shows up when we feel we are being treated unfairly, feel threatened, or are interrupted while trying to reach a goal. In that sense anger works as a signal that something matters to us.
Angry people may overestimate their intelligence
One study often cited in this debate looked at how anger relates to how clever people think they are. In a 2018 paper in Intelligence, Marcin Zajenkowski and Gilles Gignac examined trait anger and self-assessed intelligence across two studies of 303 and 225 participants.
Once neuroticism was taken into account, people higher in trait anger rated their own intelligence more highly, even after controlling for their scores on an objective intelligence test. In the second study, narcissism partly explained the link. The authors suggested that trait anger may have two faces, one tied to anxiety and one tied to overconfidence.
This does not show that angry people are less intelligent. It suggests that a tendency towards anger can come with an inflated sense of one’s own ability, which is a different and more subtle finding.
How anger changes thinking
Anger also affects judgement in the moment. In a widely cited review in the Journal of Behavioral Decision Making, Jennifer Lerner and Larissa Tiedens described how anger shapes decision making. They argued that anger tends to come with a sense of certainty and control, which can make people more optimistic about risk and more likely to rely on quick mental shortcuts.
The review also noted that anger differs from other negative emotions. Fear tends to make people cautious, while anger tends to make them act. That drive can be useful when something needs fixing, but it can also lead to snap decisions that look less wise later.
Interestingly, some research has even linked anger to positive outcomes in certain contexts, such as helping people pursue their goals and, for some, contributing to happiness when it feels appropriate to the situation. Anger, in other words, is not simply a flaw to be stamped out.
Why the myth sticks
The myth probably persists because explosive anger can look like a loss of reasoning, and people who stay calm often seem more thoughtful. Social media clips also tend to show the worst moments of someone’s day, stripped of context.
Intelligence and emotional regulation are different skills. A highly capable person can still struggle with their temper, and someone who finds academic tasks hard may be very good at managing conflict. Judging intelligence by anger mixes up two separate things.
Healthy ways to manage anger
Managing anger is a skill that anyone can build. The NHS suggests a few practical approaches:
- Pause first: Counting to 10 or stepping away gives your body time to settle before you respond.
- Notice the signs: Mindfulness can help you spot tension early, before it turns into an outburst.
- Move your body: Regular exercise can reduce stress and help release built-up tension.
- Try self-help: Cognitive behavioural therapy techniques can help you challenge angry thoughts.
Anger also tends to spill into close relationships, where stress builds quickly. Our piece on reducing anger and stress in relationships offers more ideas.
When to get help
If anger is affecting your relationships, work, or health, or if you have hurt someone or behaved in an abusive way, the NHS advises speaking to a GP. In England you can also refer yourself to NHS Talking Therapies.
If you are struggling and need to talk, you can call Samaritans free on 116 123 at any time. If anyone is in immediate danger, call 999.
FAQs
- Is anger a sign of low intelligence? No. Research does not show that feeling anger means someone is less intelligent, and anger is a normal emotion.
- Do angry people think they are smarter? One 2018 study found that people higher in trait anger rated their own intelligence more highly, even after accounting for test scores.
- Does anger affect decision making? Yes. Anger can bring a sense of certainty and control, which may lead to riskier choices and quicker judgements.
- When should I get help for anger? Speak to a GP if anger is harming your relationships, work, or health, or if you have behaved in an abusive way.
Takeaway
Anger is not a sign of low intelligence, and almost everyone feels it. What research does suggest is that anger can make people overconfident about their abilities and quicker to take risks. Learning to pause, notice the signs, and seek support when needed matters far more than whether you ever get angry.
