XXICognitive Bias
Sunk Cost Fallacy
Your bias is Sunk Cost Fallacy. Continuing a position because of past investment.
Why This Bias Happens
To abandon a costly path feels like self-accusation. So we pay again to avoid admitting the first loss.
Example 1
Seneca writes that wise people do not persist simply because they have begun. They choose the better road once it appears.
Example 2
Behavioral studies show escalating commitment to failing projects when decision-makers feel responsible for prior investments.
