Cognitive dissonance, as explained by Leon Festinger, occurs when actions and beliefs clash, causing discomfort. In trading, this happens when traders ignore evidence that contradicts their strategies, driven by emotion or fear of being wrong. Confirmation bias (Peter Wason) reinforces this by filtering out conflicting information, and the Dunning-Kruger effect leads inexperienced traders to overestimate their abilities. To succeed, traders must confront these biases, avoid overconfidence, and recognize their limitations. Success in trading requires self-awareness, resilience, and a disciplined approach to risk management. Embracing failure, criticism, and rigorous backtesting can help transform trading into a professional pursuit. Ultimately, success isn’t guaranteed, but with hard work and persistence, it’s achievable.
