The café smelled like burned sugar and wet wool the afternoon I first started listening properly. Not to music, not to the scrape of chairs on tile or the hiss of the espresso machine, but to the river of words sliding past me from every direction. Two students arguing about a group project, a man on a loud phone call, a couple on what sounded like a third or fourth date. Their sentences floated through the steam and chatter like birds crossing the same patch of sky, different colors, same wings. And slowly, something strange began to stand out: the way certain phrases kept repeating, heavy and blunt, as if everyone had borrowed them from the same dusty drawer.
Psychologists, as it turns out, have been paying attention to these drawers of language for years. They don’t use them to judge people as “smart” or “stupid”—at least, not if they’re good at their jobs—but to understand how thinking styles show up in daily conversations. Some phrases, research suggests, are more common among people who lean toward rigid, black‑and‑white, low‑complexity thinking. It’s not that a single sentence can expose someone’s IQ score; life is messier than that. But our favorite verbal habits can reveal the shape of the mental furniture we keep inside our heads.
The real story here is not about mocking “low‑IQ people.” It’s about recognizing when our own language quietly flattens the world, when we swap curiosity for certainty, nuance for slogans. If you listen closely—to others, and to yourself—you may start to hear seven particular phrases ring out like warning bells.
1. “It Is What It Is” – The Sigh That Shuts the Door
There’s a special kind of silence that falls after someone says, “It is what it is.” Not a peaceful silence, like snowfall on a back road, but the dull quiet of a slammed door. The phrase hangs in the air, heavy and lifeless, and the conversation wilts around it.
Psychologically, this sentence is a surrender flag. It signals learned helplessness—the belief that nothing can be changed, so thinking more deeply is pointless. People with low cognitive engagement tend to reach for it when a situation demands effortful problem‑solving, emotional complexity, or uncomfortable self‑reflection. Rather than explore choices, question assumptions, or ask for help, they drop this brick of words and walk away.
Researchers studying what’s called a “need for cognition” have long noticed the split: some people enjoy wrestling with hard questions; others avoid mental effort the way a cat avoids bathtime. “It is what it is” belongs to that second camp. It marks the end of thinking, not the beginning.
Of course, everyone says it sometimes. The difference lies in frequency and function. When used habitually, it becomes a psychological off-switch—especially common among those who have never been encouraged, or never learned how, to sit with complexity. Compared with more reflective responses like “What can we actually change here?” or “I don’t like this, but let’s figure out options,” this phrase shrinks the mental landscape to a bare, grey field.
2. “That’s Just How I Am” – The Cemented Personality
A friend once told me this while tapping ash from his cigarette into a coffee cup: “I’m always late, man. That’s just how I am.” The clock on the wall disagreed; so did his frustrated partner sitting beside him. But the phrase landed like a locked gate. No more negotiation. No more possibility.
Psychologically, “That’s just how I am” is a cousin of “It is what it is,” but turned inward. It reflects what Carol Dweck’s research calls a fixed mindset: the belief that abilities, traits, and habits are carved in stone. People with lower cognitive flexibility—often correlated with lower measured intelligence and less exposure to challenging problem‑solving—are more likely to view personality as a static thing instead of a work in progress.
The trap here isn’t just stubbornness. It’s a rejection of self‑examination. Instead of asking “Why do I react this way?” or “What would it take to change?” the phrase builds a short, thick wall around the ego. Inside that wall, nothing grows. Blame can be safely redirected outward—to the world, to others, to “how things are.”
Used sparingly, the sentence might be an attempt at setting boundaries: “I’m introverted; that’s just how I am.” But when it shows up as a reflex every time growth is requested—arriving on time, communicating better, learning a new skill—it becomes a linguistic shield. Psychology sees that shield more often among people who lack either the tools or the confidence to believe in their own capacity for change.
3. “Whatever” – The Shrug That Cancels Connection
“Whatever” is barely a word; it’s more like a verbal eye‑roll rolled into a single puff of air. Spoken softly, it’s a withdrawal. Spoken sharply, it’s a little knife.
From a psychological point of view, “Whatever” is a classic marker of low elaborative thinking. It shows up when someone either can’t or won’t articulate their feelings, reasons, or preferences. People with stronger verbal and abstract reasoning skills tend to couch disagreements in more specific language—“I see it differently because…” or “I’m frustrated that…” Those with less practice or ability at turning inner states into words often default to dismissive shortcuts.
That doesn’t mean the person is empty inside; far from it. Instead, there’s a gap between emotion and expression—a narrow bridge with missing planks. Saying “Whatever” allows them to exit the discomfort of that gap. It’s a way to avoid cognitive and emotional work: naming the problem, exploring compromise, tolerating tension.
Over time, frequent use of “Whatever” erodes relationships. It tells the other person: “Your perspective doesn’t matter enough for me to bother with full sentences.” In studies of conflict communication, contempt and dismissal rank among the top predictors of relational breakdown. You can hear tiny shards of that contempt in each flat “Whatever.”
4. “That’s Stupid” – The Blunt Club Against Complexity
There’s a certain kind of person who stands at the edge of every new idea swinging this word like a dull club: “That’s stupid.” No questions asked. No curiosity offered. Just instant judgment, delivered with the bored confidence of someone who believes they’ve already seen everything worth seeing.
This phrase gives psychologists a small but telling clue: a low tolerance for cognitive complexity. Calling something “stupid” is seductively easy. It requires almost no mental effort—no break down of arguments, no search for evidence, no attempt to understand context. Compared to “I don’t agree because…” or “I don’t understand how that would work,” it’s a verbal drive‑by.
Research on cognitive reflection—the ability to override a gut reaction and think more carefully—shows that people who struggle with this tend to prefer simple, emotionally satisfying labels. “Smart” or “stupid,” “good” or “bad.” The middle ground, the “I’m not sure, let’s unpack this,” demands more mental fuel than they’re willing or able to burn.
More subtly, “That’s stupid” protects the speaker’s ego. If a new idea threatens their worldview, dismissing it outright keeps their internal map from being redrawn. In this way, the phrase acts like psychological bubble wrap: comforting, noisy, and ultimately preventing any real impact.
5. “Everybody Knows…” – The Lazy Crowd
Listen closely the next time someone begins a sentence with “Everybody knows…” You’ll almost feel the weight of an invisible crowd leaning in behind them. It sounds powerful, like an army of agreement. But when you look for the soldiers, the field is suspiciously empty.
“Everybody knows…” is a linguistic shortcut for borrowed certainty. Instead of citing evidence, reflecting on sources, or acknowledging doubt, the speaker hides behind an imagined majority. Psychologically, this connects to what’s called the bandwagon effect and to lower levels of independent analytical thinking. Studies consistently find that individuals with weaker critical thinking skills are more susceptible to “social proof”—the assumption that if many people believe something, it must be true.
People with stronger reasoning habits may still reference consensus, but they usually qualify it: “Most studies suggest…” or “In my experience, a lot of people…” The absoluteness of “Everybody knows…” leaves no room for exceptions or nuance. It paints knowledge as a blunt object: either you have it or you’re an outsider.
In casual conversations, this phrase often prefaces myths and half‑truths: “Everybody knows men are better at math,” or “Everybody knows therapy is for crazy people.” The wider and more sweeping the claim, the more likely it reflects not facts but inherited stereotypes. Psychology flags its frequent use as a red light for low skepticism—and, sometimes, for low willingness to think alone.
6. “I Don’t Care” – The Quiet Mask of Avoidance
At first glance, “I don’t care” seems like indifference: a shrug at the universe. But if you look closer, you’ll often find something trembling underneath—fear of failure, fear of judgment, fear of having to try.
Psychologically, this phrase often masks avoidance coping. Instead of confronting a challenge (“This is hard for me”), a potential loss (“I might not get what I want”), or a vulnerability (“Your opinion matters to me”), the speaker pre‑emptively burns the bridge: “I don’t care.” When used habitually, it’s associated with lower emotional intelligence and a more fragile sense of self—traits that can co‑occur with lower cognitive complexity.
In classrooms, you hear it from students seconds after a bad grade. In relationships, it slips out when partners feel dismissed or overwhelmed. In both cases, what’s really being said is closer to “Caring would hurt, so I’m disowning the feeling.” Compared to more mature responses like “I’m disappointed, but I’ll try again” or “This matters to me, even though it’s scary,” “I don’t care” is a cheap escape hatch.
Over time, that escape hatch leads somewhere barren. If nothing matters, nothing is worth the work of understanding, improving, or protecting. Low curiosity, low investment, low reflection—all of these live comfortably next door to low mental engagement. The more often someone leans on “I don’t care,” the more their world quietly flattens around them.
7. “It’s Just Common Sense” – The Illusion of Obviousness
“It’s just common sense,” said the man in line behind me at the hardware store, explaining loudly how to “fix the economy” between price checks. His solution, delivered with the ease of a weather report, ignored about fifty years of economic research. But wrapped in those four words was a shimmering shield: if you disagreed, you weren’t offering another perspective—you were betraying obvious truth.
From a psychological standpoint, “It’s just common sense” is one of the subtler phrases on this list. It sounds reasonable. Who could be against common sense? Yet, as cognitive scientists like Daniel Kahneman have shown, what feels like “obvious truth” is often just our brain’s fast, intuitive system talking. And that system, while useful, is riddled with biases.
People with higher reflective thinking ability tend to distrust their immediate “this is obvious” feeling, at least a little. They’ve learned that complex problems—climate change, inequality, mental health—don’t yield to snap answers. Lower‑IQ individuals, or those less trained in analytical thought, are more likely to lean heavily on gut‑level “common sense” and treat it as universal law.
When someone says “It’s just common sense,” what they usually mean is “This fits neatly into my existing mental model, so I haven’t bothered to examine it.” The phrase discourages questions. It frames disagreement as a failure of basic reasoning rather than a possible sign that the issue is… not so simple.
The Subtle Patterns Behind These Phrases
Seen one at a time, each of these phrases could belong to anyone, on a bad day or in a tired moment. But when you put them side by side, a pattern begins to emerge—one that psychology has been mapping for decades. Here’s how these verbal habits cluster together beneath the surface:
| Phrase | Underlying Habit | What It Often Replaces |
|---|---|---|
| It is what it is | Mental surrender | Problem‑solving, brainstorming |
| That’s just how I am | Fixed mindset | Self‑reflection, growth |
| Whatever | Low emotional articulation | Honest dialogue, negotiation |
| That’s stupid | Low tolerance for complexity | Evaluation, curiosity |
| Everybody knows… | Reliance on social proof | Evidence, independent thought |
| I don’t care | Avoidance coping | Vulnerability, investment |
| It’s just common sense | Overconfidence in intuition | Analysis, nuance |
What links them isn’t just intelligence in the narrow, test‑score sense. It’s openness versus closure. Curiosity versus retreat. Each phrase draws the curtains a little tighter around the mind, shutting out fresh air in favor of stale certainty.
But language, like a forest trail, can be walked in another direction.
Turning the Lens Back on Ourselves
It would be tempting to use these seven phrases as a secret checklist, a way of sizing people up in line at the grocery store or at holiday dinners. He says “Whatever” a lot; she leans on “Everybody knows…” Maybe they’re not so bright. That kind of thinking, ironically, would be its own form of “That’s stupid”—a cheap shortcut, a refusal to see the full picture.
Psychology reminds us that IQ is only one slice of a much larger pie: upbringing, trauma, schooling, culture, mental health, and simple exhaustion all shape the words that tumble out of our mouths. A brilliant person under stress can sound shallow; a quiet person with average test scores can ask a question that cuts straight to the heart of a problem.
The more useful, humbling move is to listen for these phrases in our own conversations. When do we say “It is what it is” instead of “What could we try?” When do we reach for “I don’t care” rather than admitting, “This matters more than I want to admit”? Each moment is a fork in the path: one direction leads toward mental tightening, the other toward expansion.
Changing the words isn’t magic. But it is a start. Swapping “That’s just how I am” for “That’s how I’ve been, but I’m working on it” cracks a small window. Replacing “Everybody knows…” with “I was taught that…” puts your belief back in your hands, where you can examine it. Letting “That’s stupid” soften into “Help me understand why you think that” invites a conversation instead of a verdict.
Back in that café, when I finally stood up to leave, the storm outside had turned the windows into sheets of moving glass. The world blurred, then sharpened as cars passed. Conversations still swirled around me—some clipped, some rich with questions, some punctuated with those familiar, heavy phrases. I stepped into the rain wondering not who was “smart” or “dumb,” but how much larger our lives could feel if we treated every sentence as a small act of choosing: between closing the mind and leaving it just a little more open.
FAQ
Do these phrases always mean someone has a low IQ?
No. Anyone can use these phrases, especially when tired, stressed, or upset. Psychology links them to certain thinking styles that can correlate with lower cognitive complexity, but a single phrase never proves anything about a person’s intelligence.
Isn’t it disrespectful to connect language with IQ?
It can be, if used to insult or judge. The point here is not to label people as “dumb,” but to notice how some common expressions shut down thinking and curiosity—traits that affect everyone, regardless of IQ.
Can changing the way I speak actually make me think better?
Over time, yes. Language and thought feed each other. Choosing more precise, curious phrases nudges your brain toward deeper reflection, better problem‑solving, and more nuanced understanding.
Are there cultures where these phrases mean something different?
Yes. Cultural context matters. Some languages and communities have similar expressions that function more as politeness or emotional shorthand. What psychology pays attention to is how often they replace reflection, not the words themselves.
What are healthier alternatives to these seven phrases?
Try replacing them with questions and specifics: “What can we change?” instead of “It is what it is,” “I’d like to get better at this” instead of “That’s just how I am,” “I’m upset because…” instead of “Whatever.” Any phrase that opens the door to more detail, feeling, or exploration is a step toward richer thinking.
