Psychology says people who are easily impressed by fools often haven’t developed these 9 discernment skills

I remember sitting across from a man who had the room’s attention.

He spoke in complete sentences. No pauses. No uncertainty. Every word landed like a fact. He used words I had to look up later. He made big promises about big things. And I remember thinking: this person knows what they’re talking about.

I was young and wanted to be impressed. I wanted to believe that someone had it figured out—and that I was lucky enough to be in the room with them.

Months later, nothing he promised had happened.

The big ideas had evaporated. The certainty that had felt so compelling now looked like rigidity. The impressive vocabulary was just a shell around emptiness.

I wasn’t the only one fooled. But I was the one who walked away wondering: how did I miss it? What was I looking at that wasn’t there?

It took me years to understand. I wasn’t bad at judging people. My discernment filters just weren’t up and running yet. I was looking at the performance instead of the process. I was impressed by confidence—without checking if it was backed by competence.

People who are drawn to those fools lack some discernment skills. Here’s what those skills actually look like.

1. Telling the difference between confidence and actual competence

Some people speak with absolute certainty. They don’t pause. Don’t hedge. And they certainly don’t leave room for doubt. Because certainty feels like authority, it’s easy to mistake one for the other.

But confidence and competence are not the same thing. A person can sound sure while being completely wrong. They can speak loudly while knowing very little. The skill isn’t about distrusting confidence—it’s about learning to check what’s underneath.

People often mistake confidence for competence because our brains equate fluency with truth. Forbes highlights research that shows increased confidence does not come with increased accuracy. When someone speaks smoothly, we assume they know what they’re talking about—even when they don’t.

The skill is learning to pause and ask: what evidence is actually behind this certainty?

2. Recognizing when someone sounds smart without actually saying anything

Some people fill space with language that sounds impressive but says very little. Complex jargon. Intellectual-sounding fluff. Words that feel important but don’t actually convey information.

It’s easy to be impressed by this. Big words feel like big thinking. But when you slow down and ask what was actually said, you often find nothing. A circle of sound with no center.

The skill is learning to listen for substance, not style. To notice when the words are doing all the work—and the ideas aren’t doing any.

3. Knowing that one good conversation proves very little

Anyone can sound good for one conversation. The real test is whether they still sound good after ten. Whether their actions match their words when no one is watching. Whether the person they presented themselves as holds up over weeks, not minutes.

Research in Current Directions in Psychological Science shows that character is best assessed through patterns of behavior over time—not isolated moments. One impressive conversation tells you little. What someone does consistently, across weeks or months, tells you everything.

I’ve learned this the hard way. People who amaze in the first meeting often fade by the fifth. The ones who don’t need to dazzle—who are the same person in a crowd as they are in a quiet room—those are the ones worth paying attention to.

4. Watching how someone treats people they don’t need anything from

One of the clearest tests of character is how someone treats people they don’t need anything from. The waitstaff. The assistant. The person with less power.

People who are only kind when it benefits them are showing you who they are. The skill is watching how they behave when there’s nothing in it for them. How they handle frustration. How they treat people who can’t do anything for them.

Greater Good Science Center cites emotional regulation—the ability to manage one’s own reactions—as a key indicator of emotional intelligence and relational trustworthiness.

5. Noticing when someone changes the subject instead of answering

When someone is losing an argument on facts, they often change the game. They attack the person instead of the idea, bringing up something irrelevant to distract. They shift the goalposts so they can claim victory without actually winning.

These moves are used constantly by people who care more about being right than being accurate. The skill is learning to name what’s happening: “That’s not what we were talking about. Let’s stay with the original question.”

I used to get drawn into these fights. But I’ve learned that when someone is doing this, they’re not trying to find the truth. They’re trying to win. And you can’t argue someone out of a position they didn’t reason themselves into.

6. Separating someone who’s fun to be around from someone worth following

Some people are fun to be around. They’re charismatic. They light up a room. You leave feeling energized, entertained, maybe even a little enchanted.

I’ve been drawn to these people. I’ve wanted to be around them, to be included in their orbit, to have their attention. But charisma is not credibility. A person can be magnetic and also unreliable. They can be compelling and also empty. I’ve learned this by following people who had the vibe—and watching them lead nowhere.

The skill is learning to separate the two. To enjoy the energy while still checking the substance. To ask: is this someone I want to follow, or just someone I enjoy being around?

7. Asking what someone has actually finished, not just planned

Some people are full of big ideas. They’ll tell you about the grand plans. The upcoming projects. The thing they’re about to do that will change everything.

The skill is learning to look at what they’ve already done. Finished projects. Completed work. Things you can point to and say: this actually happened. Promises are cheap. Results are expensive. And people who can’t show you what they’ve built are often people who build nothing at all.

I’ve learned to ask: what have you finished? Not what are you planning. What’s done?

8. Asking why someone is saying what they’re saying

This is one of the most important questions you can ask: Why is this person telling me this right now?

Sometimes the answer is genuine. They’re sharing because they think it will help. Because they’ve been where you are. Because they have nothing to gain and still want to offer something.

Sometimes the answer is something else. They’re selling. Recruiting. Building their own status by offering wisdom that serves their interests. They’re telling you what they want you to believe—not what’s true.

The skill isn’t cynicism. It’s awareness. It’s asking what someone has to gain—and deciding whether their gain aligns with what you need.

9. Knowing whether the knowledge goes past the surface

Anyone can speak at level one. They can give you the headline, the summary, the version that sounds good on the surface. The question is whether they can go deeper.

Ask a follow-up question. How does that work? What’s behind that? What’s the mechanism?

Research in the National Library of Medicine shows that people who genuinely understand a subject can explain it with specificity and nuance, while those who don’t tend to stay at the surface level.

The people who know their stuff don’t mind being asked about it. The people who don’t will try to make you feel like you shouldn’t have asked.
