If You Avoid These 10 Things, You Are Smarter Than Most

Most people chase intelligence by adding more. The smartest people quietly subtract: cutting out the habits, distractions, and decisions that hold them back.

Most of us spend a surprising amount of our mental energy doing things that quietly make us less intelligent.

Not because we are careless or lazy. But because we have habits that feel completely normal, even productive, in the moment.

We talk endlessly about what smart people do.

But the more honest and useful question is:

What do they stop doing?

Because the path to sharper thinking is not always about adding more.

Sometimes it is about cutting the dead weight.

So, let's dive into the habits that separate people who get smarter from those who spin their wheels.

If several of these hit really close to home, that's the point. Examining these habits and avoiding them will help you become more intelligent.

1. You Let Emotions Drive the Car

Feeling something deeply is not the problem. Obeying every feeling as if it's the absolute truth. That's the trap.

Highly intelligent people feel everything too. They know the difference between experiencing an emotion and being ruled by it.

Psychologist Daniel Goleman, who wrote the landmark book Emotional Intelligence: Why It Can Matter More Than IQ, spent decades studying why some brilliant people derail while others thrive.

The ones who thrive have learned to use emotions as data, not directives.

They ask themselves this question:

What is this feeling trying to tell me?

And then they decide, consciously, what to do about it.

Think about the last time you fired off an angry email you later regretted, or made a big decision while still raw from a rough day.

That's not low intelligence. That's just a skill that hasn't been practiced yet.

And it's very much a skill.

Research consistently shows that emotional regulation is one of the strongest predictors of success across every domain of life.

"Anyone can be angry, that is easy. But to be angry with the right person, to the right degree, at the right time, for the right purpose, and in the right way. That is not within everybody's power and is not easy." — Aristotle, an Ancient Greek philosopher, student of Plato, and one of history's most influential thinkers

2. You Multitask

Multitasking is one of the greatest lies modern culture has sold us.

We wear it like a badge.

"I'm great at multitasking!"

This is something people say with genuine pride.

And yet the science says this:

Multitasking makes you worse at everything you are trying to do simultaneously.

Stanford University researchers put this to the test directly. They studied heavy multitaskers versus people who focused on one thing at a time. The multitaskers performed worse on all cognitive measures: attention, memory, and task-switching.

Research from Stanford found they couldn't keep things separate in their minds and were constantly pulled toward whatever task they weren't doing.

That's not productivity. That's mental chaos dressed up as efficiency.

There's also a sobering finding. During cognitive tasks, multitasking caused IQ scores to drop by an amount equivalent to missing a full night of sleep.

Highly intelligent people protect their focus like the finite, precious resource it is.

• They do one thing.
• They finish it.
• Then they move on.

Your attention is your most valuable asset. Multitasking is just spending it on credit.

3. You Think You Already Know Enough

The smartest people you'll ever meet are almost always the most curious, the most willing to say "I don't know," and the most eager to be wrong.

That's not false humility. That's how the sharpest minds stay sharp.

There's a famous psychological phenomenon called the Dunning-Kruger Effect, first studied at Cornell University by David Dunning and Justin Kruger.

Their research found that people scoring in the bottom quartile of ability consistently overestimated their performance, sometimes by a stunning margin.

Meanwhile, the genuinely skilled tended to underestimate their abilities. The more you truly know, the more clearly you see how much you don't.

In practice, this means that people who have stopped learning often don't realize they have.

They feel confident and informed.

And that feeling of certainty is exactly what keeps them from growing.

Highly intelligent people treat every conversation, every book, and every failure as their best teacher.

They are not performing humility. They genuinely believe there is always more to understand.

"The more I learn, the more I realize how much I don't know." — Albert Einstein, a Nobel Prize-winning theoretical physicist and one of the most brilliant scientific minds in human history

4. You Gossip and Tear People Down

Gossip is seductive. It creates an instant sense of closeness, fills awkward silence, and gives you something juicy to share.

But it comes with a hidden price that smart people have figured out.

If you talk about others behind their backs, everyone in the room quietly assumes you'll do the same to them.

Highly intelligent people are not saints.

They notice bad behavior, unfair situations, and frustrating people, just like everyone else. The difference is in where they take those observations.

• They address issues directly, bring concerns to the right people, or simply let it go.
• They don't turn other people's struggles into entertainment.
• They understand that every word you say is a signal about your character, not just the subject you are discussing.

There's also a focus issue.

Spending mental energy analyzing, judging, and discussing other people is energy not spent on your own work, growth, and goals.

As the saying goes:

Great minds discuss ideas, average minds discuss events, small minds discuss people.

What you say about others when they are not in the room is who you actually are.

5. You Chase Perfection Over Progress

Perfectionism sounds virtuous. High standards. Attention to detail.

But in practice, perfectionism is often fear wearing a very respectable disguise.

• Fear of judgment.
• Fear of failure.
• Fear of putting something real out into the world

Having it be imperfect, which is to say, human.

Researchers at the Wharton School of Business have studied what separates consistently successful people from those who plateau.

Risk tolerance, specifically the willingness to try, fail, and try again, came up again and again.

The most accomplished people are not the ones who got everything right. They are the ones who kept going when they got it wrong.

Highly intelligent people understand that done and learning almost always beats perfect and waiting.

They ship the work, get the feedback, and improve. They don't let the pursuit of a flawless version prevent the existence of a good one.

"I have not failed. I've just found 10,000 ways that won't work." — Thomas Edison, an American inventor who held over 1,000 patents, including the phonograph and practical incandescent lightbulb

6. You Judge People Without Walking in Their Shoes

Snap judgments are a feature of the human brain, not a bug. Our minds are wired to categorize quickly, and it's a survival mechanism.

But highly intelligent people have learned to catch that first judgment and hold it loosely, knowing it's almost certainly incomplete.

What fills the space where judgment used to live?

Curiosity, mostly. And empathy.

The recognition that every person is navigating their own invisible story.

• The struggles you can't see from the outside.
• The history you haven't been told.
• The pressures you haven't felt.

That doesn't mean excusing everything. It means not pretending you have the full picture when you never do.

This isn't just philosophically admirable, but practically useful.

People who reserve judgment tend to build better relationships, make better decisions, and see opportunities that others miss because they dismiss people too quickly.

Judging someone's chapter 12 when you only read chapter 1 isn't intelligence. It's impatience.

7. You Stay Stuck in One Way of Thinking

The most dangerous words in anyone's vocabulary might be.

"That's just how I see it."

Not because perspective is bad, it's essential, but because treating one perspective as the final word is how people stop growing entirely.

Intelligent people actively seek out views that challenge their own. Not to lose themselves, but to sharpen their thinking against something with real resistance.

Cognitive scientists call the alternative fixed thinking patterns, or mental ruts, in which we keep reaching the same conclusions despite new evidence.

Research by Stanford psychologist Carol Dweck on growth versus fixed mindsets shows that people who believe their abilities can grow actually do grow, in measurable, lasting ways.

Meanwhile, those who believe they are stuck with the intelligence they have tend to confirm that belief through their choices.

Highly intelligent people read the argument they disagree with before they dismiss it.

They ask:

"What would I have to believe for this to make sense?"

That question alone can unlock more understanding than a hundred hours of consuming only what already confirms what you think.

"The measure of intelligence is the ability to change." — Albert Einstein, a theoretical physicist and author of the theory of relativity

8. You Blame Everything and Everyone Else

There's a comfortable story available to all of us at any moment.

It's someone else's fault.

The economy, the timing, the people around us, and bad luck.

And sometimes, honestly, those things really are part of it.

But highly intelligent people know there's a massive difference between acknowledging external factors and handing them all your power.

When everything bad that happens to you is someone else's doing, you are also quietly saying that nothing good can happen without their permission.

That's a cage built from resentment, and it's one you can only unlock yourself.

Research in psychology consistently links an internal locus of control, or the belief that your choices genuinely shape your outcomes, with higher achievement, better mental health, and greater resilience under pressure.

This doesn't mean blaming yourself for everything either.

It means asking the braver, more productive question:

"Given the situation I'm in, what can I actually do?"

That question is the beginning of real intelligence, or the kind that moves things.

You can be right about who's to blame and still be stuck. Smart people choose to be unstuck.

9. You Skip Self-Reflection

Most people review their work. Very few review themselves.

And that gap, between analyzing what you did and honestly examining who you were while doing it, is where a lot of potential quietly evaporates.

Self-awareness is not a personality trait you either have or don't.

Research from UC Berkeley's Greater Good Science Center frames it as a practice, or something you build through consistent, honest effort.

That includes not just private journaling and introspection, but also actively seeking feedback from people who will tell you the truth and being willing to hear it without immediately defending yourself.

Highly intelligent people know that blind spots are called blind spots for a reason: you can't see them on your own.

They create systems, like regular check-ins, honest conversations, and reflection practices, that make self-knowledge a habit rather than an occasional crisis.

"Knowing yourself is the beginning of all wisdom." — Aristotle, a philosopher whose work on ethics, logic, and science laid foundations that shaped Western thought for over two millennia

10. You Neglect Rest and Self-Care

This one will bother the people who wear exhaustion like a trophy. We have built a culture that glorifies being busy or that treats sleep deprivation as a sign of dedication and rest as laziness.

Highly intelligent people have largely seen through this myth because the evidence against it is overwhelming.

Your brain isn't a machine that works better the harder you push it. It's an organ that requires recovery, nutrition, sleep, and downtime to perform at its peak.

Research links chronic sleep deprivation to measurably impaired memory, decision-making, and creative thinking, or the very faculties you are trying to develop.

Some of the most innovative thinking happens precisely when the brain is resting, not working. That's when it consolidates, connects, and generates the unexpected insights that focused effort can't always produce.

Taking care of yourself isn't self-indulgence. It is, quite literally, the maintenance of the only tool you have.

Highly intelligent people treat their physical and mental health not as a luxury they'll get to someday, but as the foundation on which everything else is built.

You cannot pour from an empty cup. And you cannot think clearly from a depleted brain.

Bringing It All Together

Intelligence is not a score on a test or the speed at which you solve puzzles. At its most useful, it's a set of habits.

It's all about the ways you move through the world that keep you honest, curious, and capable of growth long after formal education ends.

Every single item on this list is something you can change.

Not overnight, and not without effort, but genuinely and durably, because none of these are fixed personality traits.

They are patterns. And patterns, with enough awareness and intention, can be rewritten.

The question comes down to whether you are willing to behave intelligently, starting today.

If even two or three of these resonated with you, that's not a reason to feel bad about yourself. It's actually a sign of the exact kind of self-awareness that separates people who grow from those who stay stuck.

The fact that you recognize the pattern is the first step to breaking it.

So pick one. Just one to start.

Don't pick the easiest one, but the most honest one. And do the work of becoming, one choice at a time, the sharpest version of yourself that you are capable of being.

You are more than capable. The only question is whether you will stop doing things that get in your way.
