Mental accounts serve as a type of restricted framing for humans where they keep things under check and comprehensible by a finite mind. The choice to invest further funds in a losing account, notwithstanding the availability of better options. This is coined as the sunk-cost fallacy and expensive error that occurs in both big and minor choices. Sunk cost fallacy is a common phenomenon for most people. Only by learning and becoming aware of the concept can people get rid of it. What is Sunk Cost Fallacy? Sunk costs are expenses that have already happened and cannot be recovered in any way. Sunk costs are unrelated to any particular occurrence and should be disregarded when making investment or project choices. When making such judgments, only relevant expenses (costs that are associated with a certain option and will vary based on that decision) should be addressed.

Example 2: A corporation invests $5 million in the construction of an aircraft. Before the aircraft is completed, the management understands that there is no market for it. The aviation business has developed, and airlines now need a unique sort of aircraft. The corporation must decide whether to complete the plane for an additional $1 million or to manufacture the new in-demand aircraft for $4 million. The $5 million already spent on the old aircraft is considered a sunk cost in this case. It should have no bearing on the outcome because the only expense that matters is the $4 million. Example 3: A business invests $10,000 in teaching staff how to utilise a new ERP system. The program reveals itself to be quite perplexing and untrustworthy. The top management team wants to abandon the new ERP system. The $10,000 spent on staff training is a sunk expense that should not be included in the decision to terminate the new ERP system.

Despite multiple setbacks and failures, the country's officials continued to invest in this jet for over three decades, despite widespread acceptance that it was a commercial disaster. Finally, the sunk cost fallacy may lead CEOs to make corporate choices motivated by fear of loss rather than excitement for the future. And this propensity applies to working activities as well.
