Have you ever felt that you were quite good at a field, enough to be able to judge others who are less qualified than you? But suddenly one day, you meet someone much better than you and that makes you realize maybe you're not that good. This is a sign that you are entering the third stage of the Dunning-Kruger effect sequence. The Dunning-Kruger effect can happen to anyone, in any field, or in any industry. Let’s go with A8 Resourse to know more what the Dunning-Kruger Effect is and how to control it. To understand more about Dunning Kruger Effect, let's find the example in the comment below.

What is the Dunning-Kruger effect?

''The Dunning-Kruger effect is a type of cognitive bias that causes people to overestimate their abilities and knowledge in a certain area''

How does the Dunning-Kruger effect work?


Stage 1: Know-nothing

When there is no knowledge of the field in question, one's confidence is zero.

Stage 2: Peak of Mount Stupid

When they start to have a little knowledge, their confidence increases dramatically. Stage 3: Valley of Despairs

When they start to study more closely, they realize their limitations and start to feel self-disappointed.  Stage 4: Slope of Enlightenment

If they continue to learn, they will expand their knowledge, and their confidence will gradually increase again.

Stage 5: Plateau of Sustainability

When they become knowledgeable in that area, the confidence will increase to a steady level.

Signs of the Dunning-Kruger effect

  • Overestimate your ability
  • Not recognize the knowledge and competency of surrounding people
  • Not be aware of self-wrong

How to overcome the Dunning-Kruger effect

  • Listen and accept the contributions of others: Only by receiving feedback can you make progress
  • Practice critical thinking: Always question what you know to challenge your beliefs and thoughts
  • Non-stop learning: Constantly learning and digging deep, you can avoid the default mindset that you are already an "expert". In short, it mean arrogance

Let’s take learning French as an example

  • Know-nothing: You’re a stranger to French, admiring people who are fluent in French
  • Peak of Mount Stupid: After learning French, you become familiar with French and feel proud of yourself. You tend to consider those who are not good at French speaking French inelegantly.
  • Valley of Despairs: Then, you realize there are a lot of advanced grammar or vocabulary new to you. You sometimes don’t really understand what you read or hear in French. Self-doubting and self-disappointment is a sign that you fall into Valley of Despairs.
  • Slope of Enlightenment: The desire to be better in French pushes you to conduct deeper research and practice using French.
  • Plateau of Sustainability: Turn learning French into a habit and obtain more joy when learning and utilizing new things in reality.
