How the Sunk Cost Fallacy Makes You Act Stupid

How the Sunk Cost Fallacy Makes You Act Stupid

Do you think you make smart, rational decisions most of the time?

Chances are good that even if you pride yourself on being rational most of the time, you still occasionally fall for the sunk cost fallacy.

What is this fallacy?

In economics, a sunk cost is any past cost that has already been paid and cannot be recovered. For example, a business may have invested a million dollars into new hardware. This money is now gone and cannot be recovered, so it shouldn’t figure into the business’s decision making process.

Or, let’s say you buy tickets to a concert. On the day of the event, you catch a cold. Even though you are sick, you decide to go to the concert because otherwise “you would have wasted your money”.

Boom! You just fell for the sunk cost fallacy.

Sure, you spent the money already. But you can’t get it back. If you aren’t going to have a good time at the concert, you only make your life worse by going.

How Often Do You Fall Into The Sunk Cost Fallacy Trap?

Unfortunately, an awful lot.

If you take a moment, you can probably think of all sorts of situations where you make irrational decisions because of the sunk cost fallacy.

To help you see how common this is, here are a few examples.

1. “I might as well keep eating because I already bought the food.”

I do this one all the time. If I go to a restaurant and become full after eating most but not all of my food, I feel compelled to eat the rest so that it isn’t “wasted”.

But in reality, nobody else will eat that food after me. It’s not getting recycled or given to poor people. It’s just thrown out.

So if I feel uncomfortable, I shouldn’t eat the food. It’s a sunk cost, and I only lose by gorging myself further.

2. “I might as well keep watching this terrible movie because I’ve watched an hour of it already.”

Or reading a terrible book that you are 100 pages into, or continuing a T.V. series on Netflix that has gone downhill, etc.

It doesn’t matter that you’ve already invested time into whatever media you are consuming. If you don’t like the movie, you can walk out of it.

I once made the mistake of staying in the theater during Dinner For Schmucks despite quickly realizing how terrible it was. It never got better, and I wasted even more of my time by staying.

3. “I might as well keep going to a bad/useless class that I paid for.”

If you join a club or take a class to learn a new skill, you might feel compelled to continue even if you don’t enjoy it.

After all, you paid the $100 entry fee and you’ve gone to 3 of the 8 sessions, so you might as well finish, right?

Of course not. If you don’t feel you are getting anything out of it, bail. Write off the money and the time you spent, and save yourself from the other five classes. Don’t waste any more of your time.

4. “I might as well continue dating someone bad for me because I’ve already invested so much in them.”

This is unfortunately all too common.

If you put a lot of emotional investment into a relationship, it can be very challenging to break it off. This can be true of any relationship, not just romantic ones. Perhaps one of your good friends is no longer a positive influence on you. Years of emotional investment makes it very uncomfortable to cut your ties, but you might have to.

Well, How Do I Free Myself?

We fall victim to the sunk cost fallacy because we are emotionally invested in whatever money, time, or any other resource we have committed in the past. The most important step to freeing yourself from making poor decisions based on sunk costs is to recognize the logical fallacy. Simply being aware of it will help you tremendously in making more rational decisions in the future.

By reading this article, you’ve already taken that huge first step.

But when that isn’t enough, I suggest you write out a pros and cons list. If the only pro of continuing to do something is to feel better about the emotional investment you’ve made, clearly you should go in the other direction.

Despite how common this fallacy is, you can see through it fairly easily most of the time. Don’t let it make you act stupidly.

13 Things Mentally Strong People Don’t Do

13 Things Mentally Strong People Don’t Do

Mentally strong people have healthy habits. They manage their emotions, thoughts, and behaviors in ways that set them up for success in life.

Take a look at these 13 things that mentally strong people don’t do so that you too can become mentally stronger.

1. They Don’t Waste Time Feeling Sorry for Themselves

Mentally strong people don’t sit around feeling sorry about their circumstances or how others have treated them. Instead, they take responsibility for their role in life and understand that life isn’t always easy or fair.

2. They Don’t Give Away Their Power

They don’t allow others to control them, and they don’t give someone else power over them. They don’t say things like, “My boss makes me feel bad,” because they understand that they are in control over their own emotions and they have a choice in how they respond.

3. They Don’t Shy Away from Change

Mentally strong people don’t try to avoid change. Instead, they welcome positive change and are willing to be flexible. They understand that change is inevitable and believe in their abilities to adapt.

4. They Don’t Waste Energy on Things They Can’t Control

You won’t hear a mentally strong person complaining over lost luggage or traffic jams. Instead, they focus on what they can control in their lives. They recognize that sometimes, the only thing they can control is their attitude.

5. They Don’t Worry About Pleasing Everyone

Mentally strong people recognize that they don’t need to please everyone all the time. They’re not afraid to say no or speak up when necessary. They strive to be kind and fair, but can handle other people being upset if they didn’t make them happy.

6. They Don’t Fear Taking Calculated Risks

They don’t take reckless or foolish risks, but don’t mind taking calculated risks. Mentally strong people spend time weighing the risks and benefits before making a big decision, and they’re fully informed of the potential downsides before they take action.

7. They Don’t Dwell on the Past

Mentally strong people don’t waste time dwelling on the past and wishing things could be different. They acknowledge their past and can say what they’ve learned from it.

However, they don’t constantly relive bad experiences or fantasize about the glory days. Instead, they live for the present and plan for the future.

8. They Don’t Make the Same Mistakes Over and Over

Mentally strong people accept responsibility for their behavior and learn from their past mistakes. As a result, they don’t keep repeating those mistakes over and over. Instead, they move on and make better decisions in the future.

9. They Don’t Resent Other People’s Success

Mentally strong people can appreciate and celebrate other people’s success in life. They don’t grow jealous or feel cheated when others surpass them. Instead, they recognize that success comes with hard work, and they are willing to work hard for their own chance at success.

10. They Don’t Give Up After the First Failure

Mentally strong people don’t view failure as a reason to give up. Instead, they use failure as an opportunity to grow and improve. They are willing to keep trying until they get it right.

11. They Don’t Fear Alone Time

Mentally strong people can tolerate being alone and they don’t fear silence. They aren’t afraid to be alone with their thoughts and they can use downtime to be productive.

They enjoy their own company and aren’t dependent on others for companionship and entertainment all the time but instead can be happy alone.

12. They Don’t Feel the World Owes Them Anything

Mentally strong people don’t feel entitled to things in life. They weren’t born with a mentality that others would take care of them or that the world must give them something. Instead, they look for opportunities based on their own merits.

13. They Don’t Expect Immediate Results

Whether they are working on improving their health or getting a new business off the ground, mentally strong people don’t expect immediate results. Instead, they apply their skills and time to the best of their ability and understand that real change takes time.
