The Boy Captain Who Thinks He Understands the Sea

The most dangerous phenomenon in trading is not "knowing nothing" — it is "knowing a little and thinking you know a lot."

This is the Dunning-Kruger Effect — a 1999 study by David Dunning and Justin Kruger of Cornell University proved that people who know little overrate how much they know, and people who know a lot underrate it.

In trading it is a graph like this:

Stage 1 — Beginner (months 0-3): "I know nothing, let me just try." Confidence: 30% — fairly afraid, so no heavy leverage, small trades, small losses.

Stage 2 — Peak of Mt. Stupid (months 3-12): "I get it! Trading is easy!" Confidence: 95% — just watched 20 YouTube videos + profited twice on demo + hit Beginner's Luck on real money, profiting 30% in the first 1-2 months. Starts showing off in Line groups / Twitter, uses 1:200, 1:500 leverage, starts teaching others. This is the most dangerous point in a trader's life. Then what happened to "Boy" in Chapter 2 happens — heavy leverage, big size, no caution → blow the account in 1-2 trades.

Stage 3 — Valley of Despair (years 1-2): "I am the dumbest person in the world." After blowing up, confidence collapses. They try to learn everything — new techniques, fundamentals, options, futures, crypto, AI bots, copy trading. Confidence: 15% — starting to accept it is harder than they thought.

Stage 4 — Slope of Enlightenment (years 2-5): "I know some things, but there is a lot I do not know." Focuses on 1-2 setups they do well, stops trying to trade every market, rejects 95% of the "opportunities" they see. Confidence: 60% — confident in their own system, humble toward the market.

Stage 5 — Plateau of Sustainability (year 5+): "I do not need to be brilliant — I just need to be consistent." Trades less — good opportunities are rare. Profit is steadier. Ignores news/social noise. Treats it like a 9-5 job, not a "passion." Confidence: 75% — confident in the system, but always with a healthy fear of the market.

Why is Stage 2 the most dangerous? Three things converge perfectly:

1. Enough knowledge to feel confident (sees charts, understands support/resistance, knows RSI) 2. Still does not know what they do not know (variance, position sizing, psychology, sample size) 3. Backed by Beginner's Luck (the first 1-2 months profit — making them believe the system works)

Result: heavy leverage + big size + no risk management = blow the account.

A quick test of which Stage you are in:

Feel "trading is easy right now, anything profits" → Stage 2 — watch out the most

Feel "trading is damn hard, the market plays games every day" → Stage 3 — do not give up

Feel "I understand 1-2 setups well, the rest I do not know" → Stage 4 — on the right track

Feel "the market is like an ordinary job, not exciting" → Stage 5 — congratulations, you survived

The lesson: if you feel "very confident" right now — that is exactly the signal to be most careful about. A skilled trader does not feel "confident" — they feel systematic fear. This is not timidity — it is respect for a market a million times bigger than you.
