This fallacy is based on the idea that because the initial investment has already been made, it would be a waste to not continue investing in the same thing. It can lead people to ignore the actual value of the investment and make decisions based on the already invested amount instead of the potential returns. This can lead to irrational decisions and missed opportunities, as people are unwilling to cut their losses and move on.
