12 Signs of a Highly Unintelligent Person, According to Science

In the next few minutes, you’re about to gain some insights that could elevate your intellectual standing. While this might not make you a certified genius, it will certainly sharpen your awareness of what sets smart people apart from the rest.

12 Signs of a Highly Unintelligent Person, According to Science

But first, let’s clear the air: intelligence is a multifaceted concept. It’s like trying to explain why cats love knocking things off tables—there’s no single answer. The traits we’ll discuss are general observations, not an all-encompassing checklist. Intelligence is too complex to be neatly boxed in.

1. Dressing Inappropriately for the Occasion

We all know that person who shows up to a formal event looking like they just rolled out of bed. Here’s a tip: that’s not a sign of brilliance. Smarter individuals understand the importance of dressing appropriately, whether it’s a tux for a formal dinner or business attire for a meeting. A study in Scientific American reveals that what you wear can influence your thinking, negotiating skills, and even your hormone levels.

2. Poor Posture

Slouching might make you look too cool to care, but it also sends the wrong signal. Confident, intelligent people maintain good posture, which not only improves your presence but can also make you feel more self-assured. While an article in New Scientist challenges some assumptions about posture, standing tall still aligns with projecting confidence.

3. Mindless Nodding

You might be an excellent nodder, but if you’re not truly listening, what’s the point? Pretending to follow a conversation without engaging is like being an extra in a Shakespeare play—just there for show. Intelligent people actively participate in discussions, even if it means nodding less and listening more. Research from ScienceDaily suggests that nodding or shaking your head can influence your own thoughts, so be mindful.

4. Jumping to Conclusions

If you’ve ever met someone who thinks they know everything, you’ve likely encountered someone who isn’t winning any IQ awards. True intelligence involves being open to new ideas and learning from experiences. A Scientific American article highlights how those who jump to conclusions often make poor decisions, choosing low-odds bets over smarter options.

5. Smoking

Don’t shoot the messenger, but smoking has been linked to lower intelligence. It’s like setting your money on fire and claiming you’ve got plenty to burn. A study cited by Reuters found a correlation between the number of cigarettes smoked and IQ levels. Maybe it’s time to invest in a healthier, more brain-friendly hobby.

6. Being Out of Touch with Reality

Not sure if the Earth is round or flat? That’s a problem. Staying grounded in reality is crucial for intelligence. A Psychology Today article discusses how perception can become someone’s reality, influencing how they view the world. If you’re not sure about basic facts, it might be time to recalibrate your understanding of the world.

7. Poor Interpersonal Skills

If your social skills are as rusty as an old tin can, it’s time for a tune-up. Intelligent people tend to be empathetic, good communicators, and able to foster win-win situations. A study in the International Journal of Educational Technology in Higher Education discusses how AI is changing the way we interact, which could impact interpersonal skills, especially in online environments.

8. Overconfidence

Bertrand Russell once said, “The fundamental cause of the trouble is that in the modern world, the stupid are cocksure while the intelligent are full of doubt.” If you think you know it all, chances are you’re not in the genius club. Embrace a bit of doubt; it’s a hallmark of intelligence. Research from ScienceDaily suggests that overconfidence often stems from the belief that intelligence is fixed and unchangeable.

9. Lack of Curiosity

Smart people are like sponges, absorbing knowledge from every corner of the universe. They’re curious about everything and can discuss a wide range of topics. If your interests are narrow, it might be time to broaden your horizons. An article from Experience Life cites studies showing a positive correlation between curiosity and intelligence.

10. Dependency on the Internet for Answers

We live in a digital age where Google can answer almost any question. But if your thinking is shallow, and you rely solely on the internet for brainpower, it might be time to unplug occasionally. True wisdom often comes from within. An article from the World Economic Forum discusses how easy access to information can alter how we perceive our own intelligence.

11. Poor Sleeping Habits

If you’re a night owl who thinks early birds are just plain boring, science might be on your side. Research reported by Psychology Today suggests that night owls tend to have higher IQs than those who stick to a more traditional sleep schedule. So if you’re burning the midnight oil, pat yourself on the back—you’re in good intellectual company. But don’t worry, early birds, there’s room for everyone in the intelligence spectrum.

12. Lack of Musical Ability

Even if you can’t tell a flute from a kazoo, don’t fret. While musicians do tend to have uniquely wired brains, you don’t need to be a maestro to be smart. However, picking up a musical instrument could unlock new cognitive abilities. Learning music can change the brain’s neurophysiology, so why not give it a try?

So, there you have it—12 signs that might suggest you’re either more intelligent or less so than you thought. If you’ve made it this far, congratulations! You’re already a little bit wiser than you were a few minutes ago. Keep seeking knowledge, stay curious, and remember: only nod your head when it’s appropriate.
