Hindsight Bias｜後見之明偏誤：結果知道之後，過去會被重新感覺成「本來就看得出來」

Hindsight bias refers to the systematic tendency, after learning an outcome, to see that outcome as more foreseeable than it actually was beforehand. Knowing what happened can distort recollection of earlier uncertainty and produce the feeling that one 'knew it all along.'

後見之明包含記憶、必然感與可預測性等不同成分；承認此偏誤不等於所有事後分析都沒有價值。
