In recent years, most of us have become aware of imposter syndrome, which has helped many people articulate the struggles they face. But while this conversation was unfolding, other people were secretly wondering, “What if I have the opposite of imposter syndrome?” It's time to bring them into the conversation. Let's talk about the Dunning-Kruger effect and how it can impact your career.
What is the Dunning-Kruger effect?
To define the Dunning-Kruger effect, we turn to psychologists David Dunning and Justin Kruger, who first identified this cognitive bias in 1999. It describes a phenomenon where people with limited knowledge or skills overestimate their own competence. Essentially, they don’t know what they don’t know—and that misplaced confidence can cause major problems, especially in the workplace.
The Dunning-Kruger effect is considered to be the opposite of imposter syndrome. While those with imposter syndrome doubt their own skills despite being competent, people experiencing the Dunning-Kruger effect lack the awareness to recognize their own limitations.
How the Dunning-Kruger effect can appear at work
The workplace is a breeding ground for the Dunning-Kruger effect. It can show up in job interviews, team projects, leadership decisions, and even everyday tasks. “It all leads to frustration and can result in career stagnation as such people resist adapting or learning from their failures,” says Max Doshay, a licensed psychologist and CEO at Monima Wellness.
There are a few common ways it plays out.
Overconfident job candidates
Someone living with the Dunning-Kruger effect might walk into an interview and confidently claim they can do the job flawlessly—regardless of how well they actually match the job description. If they don’t get hired, they may struggle to understand why. But if they do land the job based on confidence rather than competence, it can lead to frustration for both them and their employer when they fail to meet expectations.
The Dunning-Kruger effect doesn’t just affect the overconfident person—it also impacts those around them. When someone dismisses their lack of knowledge and skills while acting overly confident, it can frustrate and demotivate colleagues who have to work with them.
Poor decision-making
A team member who assumes they know best might dismiss expert advice, ignore important details, or take on tasks beyond their skill level, creating problems for the entire organization. Once this overconfidence meets with important decisions, it can lead to costly mistakes based only on their faulty self-assessment.
Resistance to feedback
Because people experiencing the Dunning-Kruger effect believe they’re highly skilled, they may resist constructive criticism. Rather than seeing feedback as an opportunity for growth, they might dismiss it, argue, or assume their colleagues simply don’t recognize their brilliance.
Strained team dynamics
Team members perceive such a person as arrogant or unapproachable, damaging morale in the team, creating conflict, and reducing team productivity. They may overshadow colleagues, insist their ideas are the best, or fail to recognize others' expertise.
How do you know if you have the Dunning-Kruger effect?
Recognizing whether you’re experiencing the Dunning-Kruger effect can be tricky—after all, the whole issue is that people with it don’t realize their own incompetence. But how can you tell the difference between healthy confidence and ignorance?
First, confidence is backed by knowledge and experience. If you’re confident in your skills but still open to learning, feedback, and improvement, that’s a good sign. On the other hand, if you find yourself dismissing criticism, overestimating your abilities compared to peers, or struggling to accept when you’re wrong, it might be time for a self-check.
It’s important to note that the Dunning-Kruger effect isn’t just about thinking highly of yourself—it’s about flaunting expertise you don’t actually have. Psychology debates whether people with this bias are aware of their ignorance or if they truly believe in their mistaken knowledge. However, self-reflection and exposure to real expertise can help mitigate the effect.
Dunning-Kruger effect: How to overcome
If you’re starting to wonder whether you’ve fallen into the Dunning-Kruger trap—congrats! That self-awareness is already a step in the right direction. Try the following strategies to develop a more accurate perception of your skills.
Develop active listening skills
If you tend to be overconfident, Doshay recommends developing active listening skills. “Make sure you listen carefully to others before responding,” he says. “This will help improve team collaboration and reduce negative feelings and arrogance from team members.”
Seek out constructive feedback
Constructive criticism is one of the best tools for identifying gaps in your knowledge. “This will help identify behaviors and actions that can be changed, what you haven't noticed on your own,” Doshay says. “Usually, overconfident people tend to avoid feedback because they don't want to hear of failure.” Actively ask colleagues, mentors, and managers for feedback on your work. And don’t just listen—apply it.

Engage in lifelong learning
The more you learn, the more you realize how much there is to know. “Once you start accepting failure or ignorance as something to learn from and not as a threat, it will push you to become a much better professional,” Doshay says. Taking courses, attending workshops, and seeking mentorship can help you recognize your strengths and limitations more accurately.
Stay humble and open-minded
Recognizing that you don’t have all the answers will be your new strength. “Make sure to regularly challenge assumptions about your skills and knowledge to foster humility and openness to learning,” Doshay says. “Such a mindset will help you form a more realistic view of your abilities.”
Regularly self-reflect
Make it a habit to evaluate your own skills and performance. Ask yourself: “What am I genuinely good at? Where do I need improvement?” When you’re honest about your abilities, you’ll be better positioned for real growth.
What if you're dealing with colleagues who have the Dunning-Kruger effect? How should you handle it?
Working with someone who overestimates their abilities can be frustrating—especially if they dismiss feedback, take on tasks they’re not equipped for, or disrupt team dynamics. Here’s how you can deal with the situation:
- Ask questions instead of arguing. Instead of pointing out their mistakes directly (which may make them defensive), ask open-ended questions that encourage self-reflection. “How did you come to that conclusion?” or “Have you considered this alternative?” can gently challenge their assumptions.
- Use data and evidence. People stuck in the Dunning-Kruger effect often reject opinions but have a harder time arguing against facts. Presenting data, reports, or expert sources can make your point without a direct confrontation.
- Encourage collaboration. Group work naturally exposes gaps in knowledge. Encouraging team-based projects can help them see their own limitations without it feeling like a personal attack.
- Redirect tasks wisely. If they’re eager to take on responsibilities they’re not qualified for, suggest alternative ways they can contribute that match their actual strengths. Frame it as playing to their skill set rather than shutting them down.
- Be patient but set boundaries. It’s important to be diplomatic, but you also need to protect your own workload and credibility. If their overconfidence is causing real issues, consider escalating the situation to leadership with a constructive approach—focusing on solutions rather than just complaints.
Overcoming the Dunning-Kruger effect
The Dunning-Kruger effect can hold professionals back—whether they’re job seekers overestimating their qualifications, employees making uninformed decisions, or team members struggling to collaborate. But self-awareness, feedback, and a commitment to learning can help anyone overcome it. The key? Stay curious, stay humble, and never assume you know it all.
