The café is loud in that soft, human way—porcelain clinking, low conversations weaving together like threads, the hiss of milk steaming. At the next table, two friends sit across from each other, one speaking in quick, bright phrases, the other answering with a shrug and the same words over and over: “Whatever. It is what it is.” Their cups cool between them. The conversation, you can almost see it, slowly flattens out.
We don’t usually notice it, but the language we reach for in moments like these says more about us than our résumés or IQ test scores ever will. Psychologists have spent decades studying how people think, reason, and argue. One thing is clear: people who struggle with complex thinking or have lower scores on traditional IQ tests are more likely to rely on certain phrases—not because they are “bad” people, but because these phrases make the world feel simple, controllable, and safe.
Of course, no single phrase can diagnose intelligence. Everyone, from genius to exhausted barista, says lazy things when they’re stressed or tired. But some expressions show up again and again in research on rigid thinking, low cognitive flexibility, and poor problem‑solving. When these phrases become someone’s default setting, they can reveal a mind that prefers shortcuts to curiosity.
Think of this not as a witch hunt for “dumb” sayings, but as a lantern you can carry into your own daily speech. As you read, notice which phrases you’ve used, or heard, or maybe grown up with. Notice how they feel in your mouth. And notice which ones shut doors—and which questions might open them again.
1. “It Is What It Is” – The Quiet Surrender
There’s a certain comfort in these five words. You can almost taste the resignation in them, like lukewarm tea. Psychologically, “It is what it is” often signals a retreat from thinking—especially when it shows up as the final word on a problem that still has options left on the table.
Researchers who study learned helplessness—a state where people stop trying to change difficult situations—have found that language of surrender tends to travel with low problem‑solving persistence. People with lower IQs, or simply with less confidence in their own thinking, are more likely to default to phrases that close off effort rather than spark new ideas.
There are times when this phrase fits: you miss the train, the concert’s over, the rain ruins your picnic. Reality is, in fact, reality. But when “It is what it is” gets trotted out during conflicts, careers, or relationships, it can be a linguistic white flag. Instead of asking, “What could we try?” or “What am I missing?” the phrase shrugs its shoulders and turns away.
Psychologically, this suggests a low tolerance for ambiguity. Complex thinkers can sit in the middle space between what is and what could be, even if it’s uncomfortable. Simpler thinkers want to land somewhere—anywhere—quickly. “It is what it is” lets them land, even if it’s on a patch of ground that could have been better explored.
2. “That’s Just the Way I Am” – The Brick Wall of Identity
Imagine saying to a river, “That’s just the way you are,” and expecting it to stop changing course. Humans are not so different. Personality psychologists have long argued that while temperament has roots in biology, behavior is astonishingly flexible. Yet you’ll often hear people say, “That’s just the way I am” as if their entire self were poured into concrete years ago and left to set.
This phrase is a cousin of “It is what it is,” but now it’s pointed inward. Studies on mindset, particularly Carol Dweck’s work on fixed versus growth mindsets, show that people who believe traits are unchangeable put in less effort to improve. They interpret mistakes as proof of permanent flaws rather than feedback.
People with lower IQ scores are statistically more likely to experience school as a place of repeated failure. Over time, the nervous system learns a defensive story: if I can’t change, then I don’t have to keep trying and failing. “That’s just the way I am” becomes armor—heavy, limiting armor that keeps growth at bay.
In conversation, this phrase often appears right after someone has gently pointed out a problem: a pattern of interrupting, a tendency to blow up, a habit of disappearing when things get hard. Instead of curiosity—“Really? I do that a lot? Tell me more”—the phrase slams the door: this is me, take it or leave it.
High‑level thinkers, in contrast, tend to see identity as a river, not a statue. They might say, “That’s how I’ve been, but I’m working on it,” or “It’s hard for me, but I can get better.” Same person, different story—and radically different future.
3. “Everyone Knows That” – The Illusion of Obviousness
“Everyone knows that.” Listen closely when someone says it. You can almost hear the air leave the room, like a door slamming softly. The phrase doesn’t just make a claim about facts—it makes a claim about belonging. If you question what “everyone knows,” you risk being marked as an outsider, maybe even as foolish.
In cognitive psychology, there’s a phenomenon called the “false consensus effect”: people overestimate how many others share their beliefs and habits. This effect tends to be stronger among those with more rigid thinking styles. Instead of seeing beliefs as one possibility among many, they see them as obvious truths that “everyone” shares.
People with lower IQs—or with less exposure to diverse perspectives—may lean on “Everyone knows that” when they feel mentally cornered. The phrase functions like a smoke bomb. Instead of defending an idea with evidence or logic, they declare it common sense and shame any dissent as ignorance.
The danger here is not just intellectual laziness but social pressure. When someone says, “Everyone knows that,” they stop the conversation before it can deepen. It’s a verbal way of putting a hand over someone else’s mouth.
More nuanced thinkers are usually more comfortable with phrases like, “Most people think,” or “In my experience,” or “From what I’ve read.” These phrases leave room for variation, for surprise, for the wildness of reality, which rarely aligns with “everyone.”
4. “That’s Stupid” – The Fastest Way to End a Thought
Two people sit on a park bench watching the late light skim the tops of the trees. One says, “What if cities planted more fruit trees so people could eat for free?” The other snorts: “That’s stupid.” You can feel the idea crumple between them like paper.
Calling something “stupid” is very different from carefully explaining why it might not work. The word is a blunt instrument. Psychologists link this style of language to low cognitive empathy and low openness to experience—both traits that correlate with reduced complex reasoning.
In research on argumentation skills, higher‑IQ individuals are more likely to use specific criticism: “That would make maintenance really hard,” or “How would we deal with pests and food safety?” Lower‑IQ individuals, on average, are more likely to use global, dismissive language: “That’s dumb,” “That’s nonsense,” “Only an idiot would think that.”
This kind of phrasing is protective. It allows the speaker to avoid being challenged. If an idea is “stupid,” then they don’t have to examine whether they misunderstood it, or whether it threatens their worldview. The insult acts as a shield.
The tragedy is that “That’s stupid” kills curiosity before it can hatch. Instead of asking questions, the brain collapses the whole moment into a single judgment. A more curious mind might say, “I don’t see how that would work—can you walk me through it?” Now the idea has a chance to breathe.
| Common Phrase | Underlying Pattern | Healthier Alternative |
|---|---|---|
| It is what it is | Resignation, avoidance of problem‑solving | “What can I still influence here?” |
| That’s just the way I am | Fixed mindset about personality | “That’s a habit I’m working on changing.” |
| Everyone knows that | False consensus, social pressure | “From what I’ve seen, many people think…” |
| That’s stupid | Dismissiveness, low curiosity | “I don’t get it yet—can you explain more?” |
| It’s not my fault | Externalizing responsibility | “Here’s the part I can own.” |
5. “It’s Not My Fault” – The Vanishing Act of Responsibility
You hear it everywhere: in customer service lines, in group projects, in family arguments over who forgot to lock the door. “It’s not my fault” is a simple sentence, but it reveals a lot about how a person understands cause and effect.
Psychologists talk about “locus of control”—whether you tend to see outcomes as shaped by your choices (internal locus) or by outside forces (external locus). An external locus isn’t always a sign of low IQ; many people in unstable, unfair environments learn to believe that nothing they do matters. But when “It’s not my fault” is a constant reflex, it can signal weak causal reasoning and poor self‑reflection, both associated with lower cognitive ability.
People who struggle to hold complex stories in mind often prefer simple ones: I’m the victim, you’re the problem, the universe is unfair. This story feels tidy. If it’s never your fault, you never have to feel guilt or shame—or learn anything useful from what just happened.
More flexible thinkers don’t fling themselves into self‑blame, but they do parse events with more nuance. Instead of “It’s not my fault,” you might hear: “The system is messed up, but I also dropped the ball here,” or “I couldn’t control the weather, but I could have left earlier.” These people can hold two truths at once: yes, life is unfair, and yes, my choices still matter.
In conversation, “It’s not my fault” is the moment when the learning curve goes flat. No questions, no new strategies, no deeper understanding of how the world actually works—just a clean exit from responsibility.
6. “You Always / You Never” – The Black‑and‑White Trap
Couples therapists can predict conflict by listening for two words: always and never. “You always ignore me.” “You never help around the house.” These phrases aren’t just emotionally loaded—they show a kind of thinking that has trouble with nuance.
Cognitive psychologists call this “dichotomous” or black‑and‑white thinking: everything is either perfect or ruined, good or bad, for or against. This style of thought shows up more in people who struggle with abstract reasoning and perspective‑taking, both of which are related to IQ.
When someone says “You always” or “You never,” they erase all the counter‑examples that would make the statement more accurate but less dramatic. “You often forget to text” might be closer to the truth, but it requires paying attention to patterns over time—a more cognitively demanding task than flinging out absolutes.
Language like this is hard on relationships because it attacks character rather than behavior. It doesn’t invite change, it predicts doom. Underneath it, there is often a fear that the brain can’t quite name: if I admit that you sometimes do show up for me, then I have to live with the messy, unpredictable reality of who you are. It’s easier to flatten you into “always” or “never.”
High‑level thinkers can still get angry, hurt, or dramatic; they’re human. But when calm returns, they tend to revise their language. “Lately, I’ve felt ignored,” they might say, or “In the last few months, I haven’t seen you help much.” Those words leave space for change, and for a more truthful, layered story.
7. “I Don’t Care” – The Escape Hatch from Complexity
Said with a shrug in a crowded hallway, “I don’t care” sounds like freedom. No one can hurt you if you don’t care. No one can expect anything from you if you float above it all. But beneath its casual surface, this phrase is often a signal of emotional shutdown and cognitive overload.
When the brain feels outmatched—by an argument, a task, a relationship—it sometimes slams on the brakes. One way that looks, out loud, is “I don’t care.” It’s easier to claim apathy than to admit confusion, frustration, or fear. People with lower IQs, who may frequently feel out of their depth in academic or technical settings, are at particular risk of using indifference as a shield.
In studies on motivation, psychologists find that engagement thrives on a sense of competence and autonomy. When you believe, deep down, that you can’t understand something, “I don’t care” becomes a kind of anesthesia. The less you care, the less it hurts when you fail.
But caring is where growth lives. A more honest, more cognitively engaged response might be, “I’m overwhelmed by this,” or “I don’t get it yet, and that frustrates me,” or even, “I’m afraid to try and look stupid.” These sentences are tender and risky, but they open the door to help, to learning, to connection.
When “I don’t care” rules a person’s speech, their world quietly shrinks. Fewer things matter. Fewer questions are asked. Fewer horizons are chased. Over time, the statement becomes self‑fulfilling: the person genuinely stops caring, and with that, stops growing.
Language as a Mirror, Not a Verdict
By now, you might feel a small knot of recognition in your chest. Maybe you’ve said all of these phrases. Most of us have. None of them, on their own, make you less intelligent or more. They’re part of the shared toolbox humans reach for when life feels confusing, unfair, or just too much.
What psychology suggests, though, is that when these phrases become a pattern—when someone leans on them like crutches day after day—they often reveal deeper habits of mind: rigidity, avoidance, helplessness, black‑and‑white thinking. Those habits tend to show up more often in people with lower measured IQs, not because they are morally lacking, but because complex thinking is harder work, and life hasn’t trained or supported them to do it.
The beauty of language, and of the brain, is that both are changeable. You can start to notice when you say “It is what it is” and experiment with “What might still be possible?” You can catch “That’s just the way I am” halfway out of your mouth and swap in “That’s hard for me, but I’m learning.” Every time you do, you give your mind a tiny workout in flexibility and nuance.
Think of your daily phrases like the footpaths that crisscross a familiar forest. The more often you walk a path, the clearer it becomes. You’re allowed to step off it. You’re allowed to wander. Sometimes, intelligence doesn’t look like a test score—it looks like catching yourself just before you say “That’s stupid,” taking a breath, and choosing instead to ask, “Tell me more. I’m listening.”
FAQ
Does using these phrases mean someone definitely has a low IQ?
No. Everyone uses these phrases sometimes. Psychology looks at patterns over time, not isolated words. Frequent, rigid use of these expressions can hint at less flexible thinking, but it’s not a diagnosis.
Can changing the way I speak really affect how I think?
Yes. Research on “linguistic relativity” and cognitive behavioral therapy shows that language and thought influence each other. Choosing more precise, curious phrases can gradually train your brain toward more complex thinking.
Are people with lower IQs doomed to think this way?
No. IQ is only one piece of cognition, and brains remain plastic throughout life. Practice, education, and supportive environments can strengthen reasoning, reflection, and communication skills at any age.
Is it rude or ableist to notice these phrases in others?
It can be, if used to judge or shame. The goal is self‑awareness and empathy, not superiority. Notice patterns in yourself first. With others, focus on understanding and asking better questions, not labeling.
How can I gently encourage deeper thinking in conversation?
Respond with curiosity rather than confrontation. When you hear a shut‑down phrase, try questions like “What makes you say that?”, “How did you come to that conclusion?”, or “What do you think we could try instead?” These open doors instead of slamming them.
