You think you know someone. Then they do something that completely shocks you. We’ve all been there. Maybe it was a coworker you thought was "lazy" who ended up carrying the entire project during a family crisis. Or perhaps it was that "mean" neighbor who was actually just grieving in silence. Essentially, to misjudge someone is to form an opinion that is either flat-out wrong or wildly unfair.
It happens in a heartbeat.
Our brains are wired for speed, not always for accuracy. We take a tiny sliver of information—a tone of voice, a choice of clothing, a single mistake—and we build a whole personality around it. Psychologists call this "thin-slicing." It’s a survival mechanism from the days when we had to decide if a stranger was a threat in under three seconds. But in 2026, using caveman logic to navigate office politics or dating apps usually leads to a mess.
When you misjudge, you aren't just making a mistake. You're closing a door. You're deciding the story is over before you’ve even finished the first chapter. And honestly? We do it to ourselves just as much as we do it to others.

What Does Misjudge Actually Mean in Practice?
At its core, the definition is simple: to judge incorrectly or unjustly. But the "how" is where things get messy. It’s not just about being "wrong." It’s about the gap between perception and reality.
Think about the classic "Fundamental Attribution Error." This is a big one in social psychology, famously studied by Edward E. Jones and Victor Harris back in 1967. Basically, when someone else messes up, we assume it’s because of who they are (their character). If they’re late, they’re "disorganized." But when we are late, it’s because of "traffic" or "the kids." We grant ourselves the grace of context while denying it to everyone else. That is the quickest way to misjudge a situation.
The different flavors of a bad call
It isn't always about people. You can misjudge distances, which leads to fender benders. You can misjudge the timing of a joke, leading to that soul-crushing silence at a dinner party. You can even misjudge your own capacity to handle a workload, which is the fast track to burnout.
- Social Misjudgment: Thinking someone is stuck-up when they’re actually just incredibly shy.
- Capacity Misjudgment: Signing up for a marathon when you haven't run a mile in three years.
- Risk Misjudgment: Putting your life savings into a "sure thing" meme coin because a guy on the internet looked successful.
We’re all guessing. Most of the time, we’re just hoping our guesses are "close enough." But "close enough" can still hurt feelings or cost money.
The Science of Why Our Brains Fail Us
Why are we so bad at this? Why do we misjudge so consistently?
Biases. They are the mental shortcuts that save us time but kill our perspective. One of the most famous is the Halo Effect. If someone is physically attractive or charming, we subconsciously decide they are also smart, kind, and trustworthy. We haven't seen any evidence of those traits, but our brain fills in the blanks to make a "complete" (and often wrong) picture.
Then there’s the Confirmation Bias. This is the stubborn one. Once you've decided your boss is out to get you, you will ignore the three times they praised your work and focus entirely on the one time they didn't reply to your email. You are looking for evidence to support your initial misjudgment.
It's a loop. A nasty one.
The Nobel Prize-winning psychologist Daniel Kahneman talked about this in Thinking, Fast and Slow. He described "System 1" (fast, intuitive, emotional) and "System 2" (slower, more deliberate, logical). Most of our misjudgments happen in System 1. It’s the "gut feeling" that feels so right but is often based on nothing more than what we had for breakfast or a bad memory from five years ago.
Real-World Stakes: When Getting it Wrong Matters
Misjudging isn't just a social faux pas. In some industries, it’s the difference between success and total collapse.
In the business world, venture capitalists misjudge founders all the time. Look at the history of Western Union. Back in 1876, they had the chance to buy Alexander Graham Bell’s telephone patent for $100,000. They turned it down. The president of the company, William Orton, reportedly called the telephone a "toy." He misjudged the entire future of communication.
In sports, it happens every draft season. Scouts misjudge players' potential constantly. Think of Tom Brady, who was the 199th pick in the 2000 NFL Draft. Six quarterbacks were taken before him. Every single team in the league misjudged his ceiling because he didn't "look" like a superstar at the combine.
And then there's the legal system. This is the heavy stuff. Research by organizations like the Innocence Project shows that eyewitness misidentification is a factor in approximately 69% of DNA exoneration cases. People misjudge what they saw in high-stress moments, and the consequences are life-altering.
How to Stop the Cycle of Misjudgment
You can't be 100% accurate. Nobody is. But you can be less wrong.
The first step is simply acknowledging that your first impression is probably a hallucination. It’s a guess. Treat it like a hypothesis, not a fact. When you meet someone new, tell yourself, "I have a feeling about this person, but I don't have the data yet."
Ask better questions. Instead of assuming you know why someone acted a certain way, ask them. It sounds too simple to work, but "Hey, I noticed you were quiet in the meeting—is everything okay?" is a lot more effective than "Wow, they’re being really difficult today."

Check your own mood. Are you tired? Hungry? Stressed? We tend to misjudge others more harshly when we feel bad ourselves. If you’re having a terrible day, you’re likely to project that onto everyone you interact with.
Practice Intellectual Humility
This is a fancy way of saying "admit you don't know everything." People who are high in intellectual humility are less likely to misjudge because they are open to new information. They don't feel the need to be "right" immediately. They can sit with the discomfort of not having an opinion yet.
Think about the last time you changed your mind about someone. What changed? Was it a conversation? A shared experience? Usually, it's because you got more "data points." The more time you spend with someone, the harder it is to keep them in a neat little box.
Why We Should Forgive Ourselves for Misjudging
Look, you're going to get it wrong. You're going to trust the wrong person, and you're going to be skeptical of someone who was actually trying to help.
The goal isn't to be a human lie detector or a perfect judge of character. The goal is to be flexible. When you realize you've misjudged someone, own it. There is a strange kind of power in saying, "I totally got you wrong, and I'm sorry." It builds a level of trust that wouldn't have existed if you’d been right from the start.
Being "wrong" is just part of being alive. The real danger isn't the misjudgment itself; it's the refusal to change your mind when the truth is staring you in the face.
Actionable Steps to Improve Your Judgment
If you want to sharpen your "people radar" and stop the cycle of bad calls, try these specific shifts in your daily life.
- The 24-Hour Rule: If you form a strong negative opinion about someone you just met, wait 24 hours before acting on it or telling someone else. Often, the "vibe" fades and you realize you were just projecting.
- Reverse the Narrative: When someone annoys you, try to come up with three plausible reasons for their behavior that have nothing to do with you. Maybe they didn't sleep. Maybe they just got bad news. Maybe they're just socially awkward.
- Seek the "Why": Focus on motivations rather than actions. If someone snaps at you, their action is rude, but their motivation might be overwhelm. Addressing the overwhelm is more productive than reacting to the rudeness.
- Audit Your Past Calls: Look back at the last three times you were "sure" about someone and ended up being wrong. What misled you? Was it their clothes? Their accent? Their confidence? Identifying your own "triggers" for misjudgment is the best way to avoid them in the future.
Start small. Tomorrow, when you find yourself labeling a stranger or a colleague, stop for one second. Remind yourself that you're seeing a tiny percentage of their life. Most people are fighting battles you know nothing about, and most of the time, your brain is just making up a story to keep itself busy. Give them—and yourself—the benefit of the doubt.
