The ‘Sunk Cost Fallacy’ and ‘Atonement Psychology’: Why is the guilt after the truth is revealed the hardest to heal?

In behavioral economics, ‘sunk cost’ refers to a price already paid and irrecoverable. And when a ‘Noble Lie’ is exposed, the protected person often falls into extreme pain and self-punishment. Cognitive Dissonance and Irreversibility: When the protected person discovers that their past ‘hatred’ and ‘acts of revenge’ towards their benefactor were all based on a falsehood, their brain falls into extreme cognitive dissonance. Irreparable Sunk Costs: The cruelest part is that the person who sacrificed for them is often deceased or beyond recovery. This means the protected person has lost the opportunity to ‘repay the debt’ and ‘express gratitude.’ This immense asymmetry of ‘paid hatred that cannot be recovered and owed gratitude that cannot be repaid’ transforms into a lifelong psychological burden, serving as the most destructive emotional bomb in dramatic conflict.
