💡 Core Insight | A sentence that breaks you down
The Dunning-Kruger Effect, simply put: the less you know, the more you think you know; the more you know, the more you feel inadequate.
Psychologists Dunning and Kruger conducted an experiment: they had a group of people solve logic problems and then score themselves. The result was that those who scored the lowest thought they were 'doing pretty well, above average'; while those who scored the highest felt they were 'just average'. The root cause is that to accurately assess your own abilities, you need the very skills you lack. If you don't even know how bad you are, how can you objectively evaluate yourself?
In trading, once beginners multiply a few times, they think they’re “the chosen one.” But experienced traders go through a full bull-bear cycle and, paradoxically, become extra anxious about every single trade. That’s the real picture of the Dunning-Kruger effect.
🎧 Real case | The crash scene of an old bull
“In a bull market, an investor followed the trend and made several times. He thought he had truly understood the market and attributed his profits to his own analytical ability, not to the market feeding him. Then he started ignoring position management, adding leverage, and chasing highs. When the market reversed, he gave it all back—principal plus interest. Later he could only laugh bitterly: ‘At the time I thought I was really great, but actually I was just a pig on the wind.’”
That’s the typical trajectory of the Dunning-Kruger effect: first you climb up to the “peak of ignorance,” and then you fall into the “valley of despair.”
⚠️ How does this thing trap you? | Three fatal schemes
It makes your blind spots invisible: not only is your skill low, but you also don’t realize you’re low. The knowledge you lack is precisely the ruler you use to evaluate “what I still need to learn”—but without that ruler, how can you measure anything?
It lets you “send your life” from the “peak of ignorance” with oversized positions: in the beginner stage, a few accidental profitable trades can make your confidence explode. At this point, you feel unstoppable—your position size keeps getting bigger, leverage keeps getting higher, and you can’t wait to go all-in. Then—one sudden blowout exposes everything.
It makes you fall straight from the “peak of ignorance” into the “valley of despair”: first you’re full of confidence, and then you lose until you start doubting life itself. Many people can’t survive the bottom of that valley and simply quit the market. But those who manage to hang on will slowly move toward the slope of sustained growth.
You can’t stand each other: beginners think the old hands are “too timid,” while old hands think beginners are “too foolish.” In fact, neither should talk down to the other—these are the two extremes of the Dunning-Kruger effect.
🔧 What to do? | Three moves to get out of the Dunning-Kruger trap
Use data to look in the mirror—don’t rely on feelings
Don’t ask “How strong do I think I am?” Go check your “win rate, risk-reward ratio, and maximum drawdown over the past 100 trades.”Profits in a bull market may be given by the broader market—not by your own ability. Use data to pour cold water on yourself.Find a “seasoned trader” you look down on and talk to them
If you think you’re especially great, go find someone with more years of trading than you—but with a more conservative style. Listen seriously to how they got burned in the past.If you “don’t know what you don’t know,” then let an external perspective help you see it reflected clearly.Learn with small money; ask for stability with big money
Split your capital into two parts: most of it is executed in a calm, low-risk way; take out 1%-2% as “tuition,” used specifically to experiment, try out different “risky moves.” Once you’ve lost that 2%, you’re done.Survive in the market first, and only then can you cross the peak of ignorance, make your way through the valley of despair, and slowly climb onto the slope of growth.
🧘 Take 30 seconds to calm down | Don’t place orders while shouting from “the peak of ignorance”
When you’ve been making a lot recently and feel like you’ve “got it”—
Close your eyes, take one deep breath. Silently say in your mind:
“How much of my profits is luck, and how much is ability? If I change the month, can I still make money?”
Open your eyes and re-examine the attribution of these trades. Don’t get carried away.
📝 Remember this line | Etch it into your mind
The lowest point of ability is often the highest peak of confidence. Questioning yourself is the beginning of maturity.
