Confidence can be loud.
But real expertise usually sounds curious.
The Dunning–Kruger Effect is a cognitive bias where individuals with lower ability or knowledge in a subject tend to overestimate their competence, while those with greater expertise may underestimate their performance.
First identified by psychologists David Dunning and Justin Kruger in 1999, the effect occurs because the skills needed to perform well are often the same skills required to evaluate one’s own ability accurately.
Today, this bias helps explain why confidence and competence don’t always align, particularly in complex discussions where true expertise requires recognizing how much there still is to learn.
Don’t forget ⬇️
1️⃣ Confidence alone isn’t evidence of expertise.
2️⃣ Curiosity is often a sign of real knowledge. Experts tend to ask more questions, not fewer. 3️⃣ Be comfortable saying “I don’t know yet. That’s usually the starting point for real learning.
4️⃣ Stay open to complexity. The more you learn about something, the more you realize how much depth it actually has.
