The sunk cost fallacy is a cognitive bias that leads people to continue investing in a failing endeavour because they have already invested a lot of time, effort, or money. This is even though the future costs of continuing the work may outweigh the potential benefits.
For example, imagine buying a ticket to a concert you are not looking forward to. You already paid for the ticket, so you feel like you must go, even if you won't enjoy the concert. This is an example of the sunk cost fallacy.
The sunk cost fallacy can lead to several problems, such as:
- Making bad decisions: When we fall victim to the sunk cost fallacy, we make decisions that are not in our best interests. We focus on our past investments instead of our decisions' future costs and benefits.
- Losing money: The sunk cost fallacy can also lead to us losing money. This is because we may continue to invest in a failing endeavour even though the future costs of continuing are more significant than the potential benefits.
- Stress and anxiety: The sunk cost fallacy can also lead to stress and anxiety. This is because we may feel trapped in a situation, not in our best interests.
There are a few things that we can do to avoid the sunk cost fallacy:
- Recognize the bias: The first step to avoiding the sunk cost fallacy is to recognize it as a bias. Once we know the bias, we can be more mindful of our decision-making and avoid making decisions based on sunk costs.
- Consider the future costs and benefits: When making a decision, it is essential to consider the future costs and benefits of our decision, not just the past costs. This will help us make decisions in our best interests, even if we have already invested much time, effort, or money into something.
- Be willing to walk away: If we continue to invest in a failing endeavour because of the sunk cost fallacy, it is crucial to walk away. This may not be easy, but it is important to remember that the future costs of continuing may outweigh the potential benefits.
The sunk cost fallacy is a common cognitive bias that can lead to several problems. By being aware of the bias and taking steps to avoid it, we can make more informed decisions and avoid making bad choices.
There are many Cognitive Biases, many more than most people realise. If you want to think your way out of a mind trap, you must first realise that you're already trapped.
