Intelligence: this bad habit, identified by a study, reveals a higher-than-average IQ

We often think that swearing betrays a lack of education. Yet research suggests a link with intelligence. So a “bad” habit could tell us a lot about our minds, in much the same way as certain cocooning habits at home reveal how we deal with stress.

What science says about intelligence and “bad” habits

A study published in 2015 in Language Sciences made a lasting impression. Participants were asked to list swear words and then other neutral categories. The greater the fluency, the higher their verbal intelligence seemed to be. So, no more known swearwords, no more words at all, a bit like exploring varied cultural exhibitions and outings.

The authors point to a statistical correlation, not a definitive label. What’s more, other teams extended the trail in 2017. In short, taboo language sometimes informs social and verbal intelligence. However, this work says nothing about a license to insult, nor does it prescribe a single way to spend the perfect New Year’s Eve.

Why does this link come up so often? Because swearing mobilizes rapid lexical and emotional networks. Consequently, this flexibility could betray an intelligence in action. Also, the brain manages context, emotion and social rules in parallel, a balance comparable to that sought when planning art- and museum-oriented tourist destinations.

“Swearing can signal a rich lexicon, not unculture.”

Big words, brain and verbal intelligence

In these tests, word access speed is key. Also, producing different swear words requires flexibility and social context. In other words, verbal intelligence is expressed through cognitive agility. It also requires memory, inhibition and attentional flexibility.

Studies on pain show that swearing has a cathartic effect. However, repetitive use quickly loses its power. On the other hand, a rare word, tactfully placed, is more soothing. In this way, the word sometimes serves as a brief emotional release valve.

• What the tests measure: verbal fluency and flexibility.
• What these results don’t say: a license to injure.
• Context of use: between close friends, or to release pressure.
• Channel the impulse: humor, self-mockery, substitute words.
• Warning signs: personal attacks, repetition, unsuitable audience.

What this habit really reveals about intelligence

In real life, swearing isn’t just a slip of the tongue. It can signal repartee, emotional regulation and practical intelligence. What’s more, the precision of the word counts for more than its volume. So you gain rapport without losing respect.

But it all depends on the setting and the people involved. Also, aiming at someone is hurtful and against the rules. Consequently, it’s better to keep the draw for the object or the idea. In short, this energy remains a resource, not a license to insult.

Swearing has many functions: humorous, cathartic, aggressive. In short, only certain forms coincide with cognitive benefits. And this is where relational intelligence makes the difference. On the other hand, it’s best to avoid the human target and contempt.

From office to home: instructions for use

At work, agree on a clear code with the team. That way, the tone remains light and no one feels targeted. What’s more, link humor to the objective to enhance collective intelligence. Then, stop if someone expresses discomfort.

At home, set rules according to age and context. However, explain the difference between relieving tension and reaching out. Also, remember that networks retain everything, even verbal impulses. Then, choose gentle synonyms when children are present.

Practical tips and limits of interpretation

Studies on swearing are still diverse in their methods. However, let’s not forget that correlation does not equal causation. Consequently, intelligence can never be reduced to a single marker. Also, samples and contexts can skew the reading.

Standards vary according to culture, age and background. A swearword that’s acceptable here may be offensive elsewhere. In short, it’s all about the place, the time and the relationship. What’s more, different platforms impose different charters.

Stay focused on your intention and your impact. Also, transform this energy into humor, mutual aid or creativity. Then it’s your relational intelligence that will leave its mark. So choose your words as you would choose your actions.
