Why Do Some People Think They’re Geniuses? The Psychology Behind Low IQ and Overconfidence
In a world where knowledge is more accessible than ever, it’s surprising to encounter people who, despite limited expertise or understanding, feel certain that they’re always right. This overconfidence is a fascinating psychological phenomenon often linked to the “Dunning-Kruger Effect.” In this post, we’ll dive into why people with lower IQs may feel superior or more intelligent than others—and how this overestimation impacts their decision-making and interactions.
The Dunning-Kruger Effect: Overconfidence Meets Incompetence
Coined by psychologists David Dunning and Justin Kruger, the Dunning-Kruger Effect describes a cognitive bias where people with low ability or knowledge in a particular area overestimate their competence. It’s not that they want to be wrong—it’s that they genuinely can’t see their own limitations. Their lack of expertise leads them to believe they know far more than they actually do, and this belief often makes them resistant to correction.
This effect occurs not only in individuals with low IQ but in anyone who is inexperienced in a certain area. However, studies show that individuals with lower cognitive abilities tend to misjudge their own abilities across various domains, from academic knowledge to practical skills, which can lead to frustrating overconfidence.

Why Some People Feel Superior Despite Limited Ability
Several factors explain why those with lower IQ or limited skills may feel smarter than everyone else. Here are a few key reasons:
1. Lack of Self-Awareness
To recognize what we don’t know, we need a certain level of self-awareness and humility. Individuals with lower IQs might struggle with accurately assessing their abilities, as they lack the mental tools to evaluate their own shortcomings. This lack of insight often results in misplaced confidence, leading to a belief that they know just as much—or more—than those around them.
2. Confirmation Bias
The confirmation bias is the tendency to seek out information that supports our beliefs and ignore information that contradicts them. Those who are overconfident in their intelligence might focus only on content that reinforces their ideas, further entrenching their sense of superiority. For instance, they might ignore well-founded scientific studies in favor of opinions or “facts” that align with their beliefs, making them feel validated regardless of accuracy.
3. Social Influence and Echo Chambers
In today’s social media-driven world, it’s easy to find communities that echo our opinions, regardless of their accuracy. Online platforms enable people to find like-minded individuals, creating echo chambers where personal beliefs go unchallenged. This environment reinforces their sense of “knowing better,” making it even more challenging to confront their own knowledge gaps.
4. Emotional Protection and Ego Preservation
Admitting gaps in understanding can be emotionally uncomfortable. For some, it’s easier to hold onto the belief that they know more than others than to accept limitations. This psychological need to protect one’s ego can drive the overconfident attitude often associated with the Dunning-Kruger Effect. Essentially, by clinging to a belief of superiority, people protect their self-worth.
Real-World Examples: When Overconfidence Takes Over
The Dunning-Kruger Effect appears in all walks of life, from financial decision-making to health advice and even in day-to-day debates. Here are some common situations where we might encounter it:
- Health and Wellness Fads: People who skim an article on health might feel emboldened to give medical advice, even if it contradicts the expertise of health professionals. Their confidence may come from the feeling that a small amount of knowledge is sufficient to make informed decisions—an assumption that can lead to risky choices.
- Political Opinions: Many individuals form strong political beliefs based on limited understanding, feeling that their views are as valid as those of experts. Political overconfidence is particularly common, as people may believe they have all the “facts” despite often relying on biased sources.
- Financial Advice: Some people assume they understand complex financial markets after reading a few headlines or social media posts, leading to high-risk investments and financial loss. In these cases, their confidence far exceeds their understanding of the market’s complexities.

Can We Avoid This Bias? Tips for Recognizing and Reducing Overconfidence
Whether we’re the ones experiencing overconfidence or we’re dealing with someone else who is, understanding the Dunning-Kruger Effect can help us avoid the pitfalls of misplaced certainty. Here are a few strategies to foster a more balanced approach:
- Practice Humility and Self-Reflection: Regularly question your own knowledge and decisions. Are there areas where you might benefit from learning more? Humility allows us to acknowledge that there’s always more to understand.
- Seek Diverse Perspectives: Step outside of your comfort zone by exploring different viewpoints. Engage with credible sources, listen to experts, and don’t shy away from opinions that challenge your own beliefs.
- Embrace Lifelong Learning: Keep a growth mindset. Intelligence isn’t fixed; it can be nurtured through continuous learning. By staying curious and open to new information, we reduce the risk of becoming overconfident in our current understanding.
- Be Cautious of Echo Chambers: When using social media, follow sources that offer reliable, factual information, and avoid falling into echo chambers. Seek out reputable experts, fact-checked news, and balanced analyses.
- Recognize Emotional Triggers: Overconfidence can sometimes stem from emotional needs rather than rationality. Be mindful of when you feel defensive about your knowledge—this might be a sign to reassess and remain open to learning.
Conclusion: Embrace the Power of Humility
While the Dunning-Kruger Effect explains why some people with low IQ feel superior, it’s not just about intelligence—it’s about awareness, humility, and a willingness to learn. Every one of us can fall into the trap of overconfidence at times. By practicing humility and nurturing a mindset of continuous growth, we can avoid the pitfalls of misplaced certainty and make more informed, balanced decisions. Remember, true intelligence isn’t just about knowing—it’s about understanding that there’s always more to learn.
