You’re in the middle of a conversation and something feels… off.
The person across from you keeps repeating the same kind of phrases, flattening every topic, shutting every door you try to open. You mention a book, they shrug it off. You share a doubt, they laugh it away. After ten minutes, your brain is begging for an exit and your phone suddenly looks very, very interesting.
We rarely say it out loud, but some expressions act like red flags for shallow thinking.
Not because people are “stupid”, but because these phrases often show a rigid, closed way of seeing the world.
And once you start spotting them, you can’t unsee them.
1. “That’s just how it is”
This sentence sounds harmless, even wise, when you hear it the first time.
Yet it often marks the exact moment a conversation stops growing. Someone raises a question about work, relationships, money, or politics, and the reply falls like a brick: “That’s just how it is.” Full stop, no nuance, no curiosity.
Psychologists often link this kind of phrase to a fixed mindset: the belief that nothing can change, so there’s no point in thinking further.
It kills exploration in three seconds flat.
Picture a colleague who hates their job.
You ask if they’ve thought about retraining or applying elsewhere. They sigh: “I’d love to, but that’s just how it is, jobs are all the same.” You suggest a free online course, or talking to HR. Same reply, same wall.
After a while, you stop offering ideas because they all bounce back like ping-pong balls hitting concrete.
The phrase becomes a shield against effort and reflection. And the worst part is, it sounds like reality, when it’s actually just resignation dressed as wisdom.
From a psychological angle, this is a classic defense mechanism. Accepting “that’s just how it is” is easier than admitting “I feel lost and I don’t know where to start.” The brain saves energy by shutting the door on complex thinking and uncomfortable emotions.
The problem is that this tiny sentence reinforces learned helplessness over time.
Each time someone says it, they’re quietly telling their brain: “You have no power here, don’t bother.” *The more this reflex installs itself, the more the person seems “low IQ”, when in reality they’re often just low curiosity.*
The phrase doesn’t reveal raw intelligence.
It reveals how much a person is willing to think beyond their comfort zone.
➡️ Dolphins and orcas have passed the evolutionary point of no return
➡️ Motivation acts as a camera lens that shapes how memories form
➡️ The mental reason people confuse emotional intensity with urgency
➡️ Invisible scaffolding of the universe’ revealed in ambitious new James Webb telescope images
➡️ With an OLED screen on 60 hours a week for 2 years, the image degraded in a strange way
➡️ This natural soil signal tells you when it’s time to stop watering, even in hot weather
➡️ Elon Musk fired so many staff he had a 20-year-old student train an entire AI engineering team
2. “It’s common sense”
At first glance, “It’s common sense” sounds like a compliment to logic.
In real conversations, it often works the opposite way. It’s used to shut down debate, to suggest that if you don’t agree, you’re just dumb or naive. Complex topics like health, parenting, or money get reduced to a single “obvious” answer, and any nuance suddenly looks like overthinking.
Behind this phrase lies a refusal to accept that reality is messy, layered, often contradictory.
Intelligence thrives on nuance. “Common sense” is sometimes just laziness dressed up as clarity.
Imagine a family dinner.
You mention a study showing that people don’t always make rational choices with money, even when they know better. Your uncle rolls his eyes: “Come on, it’s common sense, you just need to save more than you spend.” He says it loud, with that tone that means: case closed.
No curiosity about why so many people are in debt. No interest in psychology, marketing manipulation, or social pressure.
He reduces a whole field of research to one moral lesson. You feel the air getting a bit heavier around the table.
Psychologically, this phrase often hides what’s called cognitive closure: the desire for quick, clean answers that keep anxiety low. Admitting that things are complex is uncomfortable. It forces us to accept uncertainty and gray areas.
People who cling to “common sense” as a universal rule tend to rely on stereotypes and personal anecdotes as proof.
They confuse “what feels obvious to me” with “what is objectively true”.
Let’s be honest: nobody really examines their own “common sense” every single day.
Yet when this phrase becomes automatic, it can signal a mind that prefers shortcuts to thinking, and certainty to learning.
3. “It’s always been like that”
This one is a close cousin of “That’s just how it is”, but with a nostalgic twist.
“It’s always been like that” often shows up when something new appears: a new tool at work, a new social rule, a new way of raising kids. Instead of asking “Does this bring something better?”, the person falls back on time as the only argument that matters.
Psychology calls this status quo bias: the irrational love for what already exists, simply because it already exists.
And this phrase is its favorite uniform.
Think about a boss refusing remote work.
You mention higher productivity, less commuting stress, lower costs. They cut you off: “We’re not doing that here, it’s always been like that.” No numbers, no argument, just tradition as a shield. The message is clear: the past is proof enough.
The same happens in families. A teenager questions a sexist or racist joke. The answer flies back: “Relax, in our family it’s always been like that.”
What is really being protected is not truth, but comfort.
From a cognitive point of view, this phrase lets people avoid the effort of reevaluating their beliefs. Rethinking habits forces the brain to work harder, compare options, feel doubt. That can be painful for self-image.
Saying “It’s always been like that” makes the old way look legitimate and the new way suspicious, without any analysis.
Over time, this reflex locks people into outdated models, and they look intellectually rigid.
The irony is that human intelligence evolved precisely to adapt to change.
Clinging to “always” and “never” is often a sign that fear is driving the bus, not reasoning.
4. “People are just stupid”
Here, the tone shifts from resignation to contempt.
“People are just stupid” is the kind of sentence you hear from someone who thinks they’re above the crowd. This global judgment flattens all human behavior into one lazy insult. No context, no empathy, no attempt to understand why people act the way they do.
In psychology, this often signals low perspective-taking: the difficulty of putting yourself in someone else’s shoes.
It looks like lucidity. It often hides a defensive arrogance.
Picture a friend talking about voters, clients, or coworkers.
The train is late? “People are just stupid, they always complain.” Someone falls for a scam? “People are just stupid, they believe everything.” A colleague is burned out? “People are just stupid, they don’t know how to say no.”
Each time, complex situations are crushed into one convenient insult.
No curiosity about social pressure, manipulation, lack of information, or mental health. Just a blanket judgment that keeps the speaker feeling superior and “smarter” than the rest of the planet.
Studies on emotional intelligence show that the ability to consider multiple explanations for a behavior is linked to more flexible thinking. When someone constantly reduces others to “stupid”, they’re not analyzing, they’re venting.
This phrase also blocks learning: if “people are just stupid”, there’s nothing to understand, no system to improve, no communication to refine.
It’s a dead end.
A genuinely sharp mind usually asks: “What made this person act that way?”
A mind that feels threatened prefers to insult and move on. It’s simpler, but it looks shallow very fast.
5. “That’s pointless”
You propose an idea.
A new routine, a book, a therapy, a side project. The answer lands immediately: “That’s pointless.” No trial, no experiment, no question about your motivation. The thing is declared useless before you even explain it.
This phrase often reveals a low tolerance for ambiguity. If the result isn’t guaranteed, visible, measurable, and quick, it’s labeled as “pointless”.
It’s a mindset that struggles with delayed gratification and deep work.
Imagine telling a colleague you’ve started journaling to clear your head.
They laugh: “Writing your feelings? That’s pointless, it doesn’t change anything.” You mention studies linking journaling to better mental health. They shrug: “If you’re sad, you just get over it.” Same pattern with reading, exercise, saving small amounts, learning a language.
If the payoff isn’t instant or spectacular, they reject it.
The result is a life lived in short bursts, with little investment in long-term growth. You feel alone with your attempts to evolve.
Psychologists talk about low future orientation: difficulty imagining a future self and acting today in their favor. “That’s pointless” is often code for “I don’t immediately see the reward, so my brain refuses to spend energy on it.”
This habit makes many people look “unintelligent”, when what’s really missing is patience and imagination.
They underestimate small actions, slow learning, compound effects.
*The truth is, most significant changes look pointless in the first weeks.*
The ability to believe in invisible progress is one of the quiet signs of higher-level thinking.
6. “You’re overthinking it”
Sometimes this phrase is caring.
It can genuinely mean “You’re torturing yourself with details that don’t matter.” But very often, “You’re overthinking it” is used to escape reflection altogether. Any attempt to analyze a situation, a relationship, a decision is brushed aside as excessive.
The result is a kind of anti-intellectual posture: feeling is allowed, but not thinking.
That might look cool and relaxed on the surface. Inside, it’s often just avoidance.
You talk to a friend about a weird comment from your partner.
You’re not obsessing, you’re trying to understand a pattern. They cut you off: “You’re overthinking it, just chill.” The same person will say the same thing if you question a company policy, a news headline, or a social trend.
After a while, you notice that any form of questioning makes them uncomfortable.
So they label it as a problem in you, instead of seeing it as a normal sign of an active mind. You start editing yourself down, just to stay “simple” enough.
In psychology, this can reflect low metacognition: weak awareness of how thinking works. For some people, all reflection beyond the immediate feels like a threat to emotional stability.
The phrase “You’re overthinking it” becomes a quick fix to avoid doubt, nuance, or vulnerability.
Yet research shows that the ability to analyze your own thoughts without drowning in them is a mark of mental maturity.
One plain-truth sentence here: reflexively mocking thought as “overthinking” is often just anti-effort disguised as chill.
Real calm can sit with complexity without rushing to shut it down.
7. “That’s just my opinion”
On paper, this phrase sounds humble.
In practice, it’s often used as armor. Someone drops a harsh or unfounded statement, then wraps it up with “That’s just my opinion” as if that magically protects it from criticism. The underlying message: “I don’t want to justify this, and you’re not allowed to challenge me.”
From a cognitive standpoint, it’s a way to avoid the work of argument, evidence, and self-correction.
Opinion is treated as sacred, not as something that can evolve.
You’re talking about vaccines, climate, or social issues.
A friend throws a claim that’s clearly false or at least very shaky. You gently bring up data, studies, or personal testimonies. They shrug: “Well, that’s just my opinion.” Conversation closed.
They’re not using opinion as a starting point for dialogue, but as a final barrier.
No matter what you bring, they retreat behind that wall. And if you insist, you become the “intolerant” one, even though you’re the one open to evidence.
Psychologists link this behavior to low epistemic humility: the difficulty of admitting “I might be wrong.” A more flexible mind sees opinions as temporary maps, not absolute truths.
When “That’s just my opinion” is used to block questions, it reflects a fragile relationship with knowledge.
The person prefers to keep their belief intact rather than risk updating it.
As a result, they appear intellectually stuck. *An opinion that refuses dialogue stops being an opinion and starts looking like a dead-end belief.*
How to respond when you hear these phrases
The goal isn’t to mentally label people as “low IQ” and walk away feeling superior.
These phrases are habits, and many of us use them without realizing it. The first step is simply to notice them, in others and in yourself. When you catch one, pause. Ask a gentle question instead of throwing a counter-attack.
For example, you can respond to “That’s just how it is” with “What makes you say that?” or “Has it always been like that for you?”
Small openings like these invite reflection without humiliation.
One big mistake is to respond with aggression or irony.
If you answer “People are just stupid” with “Well, that’s a stupid thing to say”, you’ve just confirmed their worldview. The other person will close up even more. They might double down on their phrases, just to protect their ego.
A more effective attitude is curious and grounded. You can say, “I used to think that too, until…” and share a story or a fact.
You’re not attacking their identity, you’re offering an alternative path. It won’t always work, and that’s okay. Your job isn’t to fix everyone. It’s to keep your own mind awake.
Sometimes the smartest thing you can do in a conversation is not to win, but to gently reopen a door that someone has slammed shut.
- Ask one more question instead of giving one more lesson.
- Replace “You’re wrong” with “What if there’s another angle?”
- Notice your own shortcuts and mentally underline them.
- Keep one or two real examples ready instead of abstract theories.
- Use silence: let the person hear their own phrase echo a bit.
Beyond “low IQ”: what these phrases really reveal
These seven phrases don’t measure someone’s brainpower.
They reveal something more subtle and more uncomfortable: our relationship with uncertainty, effort, and change. A very educated person can repeat them all day long. A person with little formal schooling can avoid them and show striking mental agility.
The real question behind each expression is simple: “Am I willing to let this topic move me, even a little?”
Some people say “That’s just how it is” because they’re exhausted. Others say “People are just stupid” because they’re disappointed. Some hide behind “That’s just my opinion” because they were humiliated once and never want to feel that again.
We’ve all been there, that moment when a lazy phrase slips out because thinking deeper feels too heavy.
Spotting these shortcuts in daily conversations isn’t a way to rank people, it’s a way to notice where curiosity is dying and where it could be gently revived. And sometimes, that work starts in the mirror, with the next sentence that’s about to leave our own mouth.

FAQ:
- Question 1Does using these phrases automatically mean someone has a low IQ?Not at all. These expressions show habits of thinking and emotional reactions, not actual measured intelligence. Everyone uses them sometimes.
- Question 2Are there phrases that “high IQ” people tend to use?They’re more likely to ask open questions, use “I might be wrong, but…” and talk about probabilities instead of certainties, yet tone and context matter more than magic words.
- Question 3How can I stop using these phrases myself?Start by catching them in your head before they reach your mouth, then replace them with a question like “What else could be true here?” or “What am I not seeing?”
- Question 4What if someone close to me constantly talks like this?You can offer gentle openings and different models of speech, but you can’t force change; sometimes the healthiest move is to limit certain topics with that person.
- Question 5Isn’t this just being too sensitive about words?Words reveal mental shortcuts and shape how we see the world; paying attention to them isn’t sensitivity, it’s a way to protect and sharpen your own thinking.
