The Sunk Cost Fallacy

An irrational commitment to past investments influencing current decisions.

What it is

It is the misconception that one needs to continue an endeavor because of the time, effort or money already invested in it, despite not getting the desired results. This fallacy leads to irrational decision-making as past investments, which cannot be recovered, are taken into account rather than focusing on future prospects.

How to use it

The Sunk Cost Fallacy in Freemium Models

The Sunk Cost Fallacy can be used to increase conversions in a tech startup by employing freemium models. When users have already invested significant time or effort into a free version of a product or service, they are more likely to convert to a paid version to avoid losing their investment. This is an example of The Sunk Cost Fallacy, as users perceive the cost of switching to another product or service as higher than the cost of upgrading, even though the time or effort they have already invested is a sunk cost and should not influence their decision.

Utilizing The Sunk Cost Fallacy in Trial Periods

In the context of trial periods, The Sunk Cost Fallacy can be used to increase conversions. After a user has spent a significant amount of time using a product or service during a trial period, they are more likely to convert to a paid subscription to avoid losing the benefits they have already gained. This is another illustration of The Sunk Cost Fallacy, as the time and effort already invested should technically not influence the decision to continue with a paid subscription.

Improving Engagement with The Sunk Cost Fallacy

The Sunk Cost Fallacy can also be used to improve user engagement in a tech startup. When users have invested significant time in using a product or service, they are more likely to continue engaging with it to avoid feeling that their investment has been wasted. This is a practical application of The Sunk Cost Fallacy, as the time already invested is a sunk cost and should not influence the decision to continue engagement.

Increasing Retention using The Sunk Cost Fallacy

The Sunk Cost Fallacy can be used to increase user retention in a tech startup. If users have already invested a significant amount of time or effort into a product or service, they are less likely to switch to a competitor. This is a clear example of The Sunk Cost Fallacy, as the investment already made should not influence the decision to stay with a particular product or service.

Applying The Sunk Cost Fallacy in Gamification

In a tech startup, The Sunk Cost Fallacy can be applied in gamification to increase conversions, retention, and engagement. If users have invested a significant amount of time or effort in progressing through levels or earning rewards, they are more likely to continue playing to avoid losing their progress. This is an instance of The Sunk Cost Fallacy, as the time and effort already invested should not influence their decision to keep playing.
