Hindsight Bias
The belief, after the fact, that the outcome was obvious all along — distorting post-trade reviews and inflating false confidence.
Hindsight bias is the "I knew it all along" phenomenon. After price makes a major move, the chart looks obvious in retrospect — the pattern is clear, the signals were screaming. You start believing that you would have caught it, should have caught it, and are worse than average for having missed it.
The same process runs in reverse on bad trades: after the stop-out, all the warning signs look unmissable. "How did I not see that?" You are pattern-matching on a chart where the outcome is already printed. That is easy. Trading in real-time — with uncertainty, noise, and incomplete information — is categorically different.
Hindsight bias corrupts post-trade reviews. To review correctly, reconstruct what you knew at the time of decision, not what is visible on the completed chart.
