and why it is believed and passed around.
The Dunning-Kruger effect is a psychological phenomenon where people who have limited knowledge or skill in something tend to overestimate how much they know or how good they are at it.
In simple terms: The less someone knows about a subject, the more confident they may be that they know it all.
How it works
- Low knowledge: Someone knows very little but feels extremely confident.
- Growing knowledge: As they learn more, they realize how much they don’t know. Their confidence often drops.
- Increasing expertise: With experience and learning, their confidence becomes more realistic.
- True expertise: They understand both what they know and what they still need to learn.
Example
Imagine someone who watches a few YouTube videos about investing and suddenly believes they’re an expert who can outperform professional investors.
Meanwhile, someone who has studied investing for 20 years may be much more cautious because they understand how complicated the market is.
Why it matters
The Dunning-Kruger effect can show up in:
- Relationships
- Politics
- Workplaces
- Parenting
- Education
- Health and fitness
- Everyday arguments
The big takeaway: Sometimes the people who are most confident aren’t necessarily the people who know the most.
And sometimes, recognizing how much you don’t know is actually a sign of growing intelligence.
This helps explain why people can believe the Social Security trust fund was stolen by Congress, that massive voter fraud affected a national election, that tariffs are paid by other countries, that socialism is taking over America and so much more nonsense easily accepted by the uninformed.
