We’ve all met someone who can turn a simple conversation into what sounds like a university lecture. They throw around impressive words, reference psychological theories, and speak with so much confidence that you almost feel silly questioning them.
But here’s the funny part: Sometimes, beneath all those fancy expressions, there’s surprisingly little being said.
Research suggests that complicated language doesn’t automatically make someone appear more intelligent. In fact, a 2006 study by psychologist Daniel Oppenheimer found that unnecessarily complex writing could actually lower perceptions of a writer’s intelligence.
Of course, using these phrases doesn’t mean someone has a low IQ. Many are perfectly reasonable when used correctly. The trouble starts when clever-sounding language replaces actual explanations.
Here are 11 expressions that can sound impressive while adding surprisingly little to a conversation.
“Research Shows…”
This one is practically a conversation cheat code.
Someone makes a bold claim, adds “research shows,” and suddenly expects everyone to accept it.
But which research? Who conducted it? What exactly did the researchers discover?
Without those details, the phrase is little more than an appeal to authority.
A 2008 study published in the Journal of Cognitive Neuroscience found that irrelevant neuroscience information could make weak explanations seem more satisfying to nonexperts.
The takeaway? Scientific language can sound convincing without strengthening an argument.
The next time someone says “research shows,” it’s perfectly reasonable to ask which study they’re referring to.
“It’s Just Common Sense”
Few phrases shut down a discussion faster than this one.
Imagine suggesting a different work schedule, only to hear your manager declare, “It’s just common sense that longer hours mean more productivity.”
Really? Based on what?
Something that feels obvious isn’t necessarily correct. People have different experiences, assumptions, and information.
Calling something common sense doesn’t explain why it’s true.
A stronger response would identify the reasoning behind the conclusion instead of assuming everyone should automatically agree.
“We Need to Leverage Synergies”
Nothing makes an ordinary office meeting sound more expensive than corporate jargon.
“We need to leverage synergies” sounds like something a highly paid consultant would announce before lunch.
But what does it actually mean?
Are two departments sharing information? Combining budgets? Reducing duplicated work?
Researchers Brown, Anicich, and Galinsky found in a 2020 study that lower relative status could increase jargon use in certain situations.
That doesn’t mean everyone who uses business jargon feels insecure. However, it shows that impressive vocabulary sometimes serves a social purpose beyond communicating information.
A clear plan beats a fancy phrase every time.
“Do Your Own Research”
This phrase can be genuinely helpful when someone encourages independent thinking.
Unfortunately, it can also become an escape hatch.
Picture someone making an outrageous claim about a company. When you politely request evidence, they respond, “Do your own research.”
Translation, in that particular situation: They’re leaving you to find the proof they haven’t provided.
Real research involves checking reliable sources, comparing evidence, and acknowledging uncertainty.
If someone has convincing information, sharing a credible starting point usually makes the conversation much more productive.
“It’s More Nuanced Than That”
Sometimes, life really is complicated.
Relationships, politics, workplace disagreements, and financial decisions rarely come with perfectly simple answers.
But announcing that something is “nuanced” without explaining the missing details isn’t particularly helpful.
Researchers Leonid Rozenblit and Frank Keil explored what they called the illusion of explanatory depth in a 2002 study.
They found that people sometimes believe they understand something better than they actually do, until they’re asked to explain it.
The practical test is simple: Ask what specific detail makes the situation more complicated.
A meaningful explanation should follow.
“Everything Is Energy”
This expression shows up everywhere, from motivational conversations to social media captions.
And depending on the context, it can carry personal or spiritual meaning.
However, when someone uses it to explain why a friendship ended or why a business failed, things get fuzzy.
What kind of energy are we discussing?
Mood? Motivation? Social behavior? Something else entirely?
In 2015, researchers led by Gordon Pennycook examined how people responded to vague, profound-sounding statements.
In one study, randomly generated statements received an average profundity rating of 2.6 out of five.
The lesson isn’t that abstract language is always meaningless. It’s that something can sound deep without offering a clear explanation.
“That’s the Dunning–Kruger Effect”
Few psychological concepts have become such popular internet insults.
Someone confidently expresses an opinion, and another person immediately declares that they’re demonstrating the Dunning–Kruger effect.
Case closed, apparently.
Except that’s not how the research works.
The original 1999 research by Justin Kruger and David Dunning examined relationships between people’s performance on particular tasks and their ability to assess that performance.
It wasn’t designed as a label for anyone who disagrees with you.
Simply calling someone overconfident doesn’t establish that they’re wrong.
If you believe someone has misunderstood something, explaining the actual mistake is far more useful.
“It’s Basic Psychology”
Ever had someone analyze your entire personality because you took three hours to answer a text?
Apparently, you’re secretly manipulative, emotionally unavailable, or playing mind games.
And their evidence?
“It’s basic psychology.”
Psychology is a serious scientific discipline. Understanding someone’s behavior usually requires much more than one isolated action.
Perhaps the person was busy. Perhaps their phone died. Perhaps they simply forgot.
Instead of assigning motives with absolute certainty, a more thoughtful approach considers several possible explanations.
“Objectively Speaking…”
This phrase often appears moments before someone shares a completely subjective opinion.
“Objectively speaking, that’s the best restaurant in town.”
According to whom?
The restaurant might have excellent reviews, reasonable prices, and convenient parking. Those are details people can evaluate.
But deciding which restaurant is “best” also depends on personal preferences.
Being objective means using clearly defined evidence and criteria, not simply announcing that your opinion is above debate.
“Correlation Doesn’t Imply Causation”
Unlike some expressions on this list, this statement is a legitimate statistical warning.
Two things happening together don’t automatically mean one caused the other.
The problem arises when someone repeats the phrase as though it completely settles a discussion.
Suppose a workplace notices that missed deadlines increase when staffing levels drop.
Someone immediately responds, “Correlation doesn’t imply causation.”
Fair point. But what happens next?
A useful discussion would investigate workload, project difficulty, staffing patterns, and alternative explanations.
Knowing a statistical principle is helpful. Applying it thoughtfully is even better.
“It’s a Paradigm Shift”
Sometimes, people make an ordinary change sound like they’ve reinvented civilization.
A company replaces its old scheduling software, and suddenly management announces a “major paradigm shift.”
Everyone nods politely.
But what fundamentally changed?
The term can describe a genuine transformation in thinking or methods. However, using it for every small update makes it lose its impact.
Instead of announcing a paradigm shift, explain what’s changing, why it matters, and what people should do differently.
Simple language often gets the job done much better.
The Bottom Line
Sounding intelligent and communicating intelligently aren’t always the same thing.
Big words, scientific references, and confident declarations can make someone seem knowledgeable, but they don’t automatically provide evidence or understanding.
The encouraging part is that good communication doesn’t require an impressive vocabulary.
It requires clear explanations, meaningful examples, reliable information, and the willingness to admit when you don’t know something.
Research on intellectual humility published in Personality and Social Psychology Bulletin in 2017 also linked recognizing one’s potential for error with greater openness and sensitivity to the strength of arguments.
So the next time a conversation fills up with complicated expressions, remember one simple question:
“What exactly do you mean by that?”
Sometimes, that question reveals more than a thousand fancy words ever come
