Worth dwelling on this huge money water for a bit
Government
The sunk cost fallacy is also prevalent in the political sphere, where it can influence policy decisions and spending. Governments may continue to fund large-scale projects that are no longer effective or relevant, simply because of the significant resources already committed. Politicians might fear the political repercussions of abandoning the project, as it could be perceived as a waste of taxpayer money. However, continuing to invest in ineffective policies or projects because of sunk costs can lead to further inefficiencies and missed opportunities for better solutions.
The Concorde fallacy is a famous example of sunk costs impacting large-scale decisions. In 1956, the Supersonic Transport Aircraft Committee met to discuss building a supersonic airplane, the Concorde. French and British engine manufacturers and their governments were involved in the project, which was estimated to cost almost 100 million dollars. Long before the project was over, it was clear that there were increasing costs and that the financial gains of the plane, once in use, would not offset them. However, the project continued. The manufacturers and governments followed through on the project because they had already made significant financial investments and dedicated a lot of time to the project. Ultimately, this led to millions of dollars wasted, and the Concorde operated for less than 30 years.
The Sunk Cost Fallacy describes our tendency to follow through on an endeavor if we have already invested time, effort, or money into it, whether or not the current costs outweigh the benefits.
