Labels like “low IQ” are blunt and often unhelpful, but psychology does study the ways language can reflect thinking styles. Certain conversational shortcuts—absolutist words, dismissive retorts, and blanket claims—tend to correlate with less reflective reasoning, overconfidence, or poor argumentation. Below are seven common phrases that research into cognition and language use associates with these kinds of thinking patterns. Note: using one of these phrases doesn’t prove anything about a person’s intelligence; context, education, stress, and culture all matter.
1. “You always…” / “You never…”
Absolutes leave no room for nuance. When people habitually use words like “always” or “never,” they’re often relying on memory shortcuts and confirmation bias instead of checking facts.
- Psychologically, absolutist language can indicate cognitive rigidity and a tendency to overgeneralize.
- In arguments, absolutes escalate conflict and shut down constructive dialogue.
2. “No offense, but…”
This prefatory phrase frequently precedes a blunt criticism or prejudiced statement. It functions as a social license: the speaker signals that they know the remark might be hurtful, but they proceed anyway.
- Research on politeness strategies shows “no offense” often reduces accountability rather than softening impact.
- Habitual use can signal poor social reasoning: prioritizing blunt expression over empathy or accuracy.
3. “I’m not a scientist, but…”
This phrase is meant to distance the speaker from error while giving their opinion extra weight. It often appears when someone asserts a claim outside their expertise.
- Cognitive humility would prompt consulting sources or acknowledging uncertainty; this phrase sometimes masks overconfidence.
- It can be a verbal shortcut that substitutes for genuine inquiry or evidence-gathering.
4. “Because I said so.”
An appeal to authority—especially a personal, unsupported one—closes discussion. It signals that the speaker believes their position is sufficient justification on its own.
- From a reasoning perspective, this bypasses evidence and encourages compliance rather than understanding.
- In debate, it converts disagreement into obedience, which doesn’t foster critical thinking.
5. “I literally can’t.”
The word “literally” is often used hyperbolically. While most people intend it as emphasis, frequent misuse can reflect sloppy language habits and weak precision in thought.
- Precise language matters for clear reasoning; habitual exaggeration blunts nuance and inflates emotional responses.
- Psychologically, hyperbolic speech can be a sign of emotional reactivity rather than reflective judgment.
6. “Whatever.”
Dismissive one-word replies shut down conversation and obscure reasoning. They’re often used when the speaker doesn’t want to engage with evidence or counterarguments.
- This phrase signals avoidance and may reflect an unwillingness to process new information.
- In social dynamics, it erodes constructive exchange and can be a tool for emotional distancing.
7. “That’s just common sense.”
Claiming “common sense” as final proof bypasses evidence and ignores complexity. What’s “common” is shaped by culture and experience; calling it “sense” gives it undue authority.
- Cognitive biases like the illusion of transparency or familiarity bias make us overvalue what feels intuitive.
- Strong thinkers remain open to counterexamples and acknowledge when issues require deeper investigation.
What this list actually shows
Language can reveal thinking patterns—shortcuts, defensiveness, and overconfidence show up in the phrases people reach for. Psychology links these patterns to lower cognitive reflection, weaker argumentation strategies, or social defensiveness, but none of these phrases is a diagnostic tool. Everyone slips into lazy phrasing sometimes; the value is in noticing patterns and choosing clearer, more curious communication.
- Replace absolutes with qualifiers: “often” or “sometimes.”
- Swap “no offense” for considerate phrasing or simply omit the insult.
- Prefer evidence or a willingness to look it up over “because I said so.”
Improving how you speak can sharpen how you think. Small conversational habits shape reasoning more than we realize—so paying attention to the phrases you use is a simple step toward clearer judgment.
