Pseudocertainty effect

Reviewed by expert Scientifically proven

The pseudocertainty effect is a cognitive bias that refers to the tendency of people to make decisions based on incomplete information or insufficient data, as long as they have a sense of certainty about the outcome. Essentially, people will choose an option that appears to have a higher probability of success, even if it is not clearly the best or most rational choice. This bias can be seen in various areas of life, from investing to dating, where people will sometimes go with their gut feeling or a sense of confidence, even if their decision-making process is flawed or incomplete.

Understanding the Pseudocertainty Effect in Conversion Rate Optimization

In conversion rate optimization, understanding how people think and make decisions is crucial to creating effective designs. One important cognitive bias to be aware of is the pseudocertainty effect.

What is the Pseudocertainty Effect?

The pseudocertainty effect is a cognitive bias that occurs when people are more likely to choose an option that they perceive as certain over an option that is merely probable. This bias leads people to overestimate the value of a sure thing, even if the alternative has a higher expected value.

How Does the Pseudocertainty Effect Affect Conversion Rate Optimization?

The pseudocertainty effect can have a significant impact on conversion rate optimization. For example, when presenting users with multiple options for a product or service, a certain guarantee or promise can increase the likelihood of conversion.

Here are some ways you can use the pseudocertainty effect in your designs:

1. Use Guarantees

Offering a guarantee or promise can increase the perceived certainty of a product or service. An example of this is the 30-day money-back guarantee frequently used by e-commerce websites. By offering such a guarantee, people feel more confident in their purchase decision, leading to higher conversion rates.

2. Highlight Certainty in Your Copy

In addition to offering guarantees, highlighting the certainty of your product or service in your copy can also increase conversions. For instance, instead of saying "Our product may improve your health," you could say "Our product will improve your health, guaranteed."

3. Use Clear Calls to Action

Using clear calls to action on your website or landing page can also increase perceived certainty. Phrases like "get started now" or "reserve your spot" promote a sense of urgency and certainty, encouraging users to take action.

4. Simplify Choices

As we've mentioned earlier, people often prefer certainty over probability. Presenting users with too many choices or options can be overwhelming, leading to indecisiveness and reduced conversion rates. Simplifying your website or landing page by reducing the number of options presented to users can help to increase conversion rates.

Conclusion

The pseudocertainty effect is a useful cognitive bias to be aware of in conversion rate optimization. By offering guarantees, highlighting certainty in your copy, using clear calls to actions, and simplifying choices, you can leverage this effect to your advantage and increase your chances of converting users.
