Home Theories Pareidolia


Reviewed by expert Scientifically proven

Pareidolia is a cognitive bias where the brain interprets random stimuli, such as shapes, patterns or sounds, as meaningful information, often seeing faces or patterns where none exist. This bias is believed to be a survival mechanism, as it helps humans quickly recognize potential threats in their environment. However, Pareidolia can also lead to false interpretations and misperceptions, especially in situations where rational analysis is necessary. In design, this bias can be used to create visual stimuli that evoke emotions and capture the users' attention, but it should be used judiciously to avoid confusing or misleading the users.

Understanding Pareidolia: How Our Brains Make Sense of Chaos

Have you ever thought you saw a face in the clouds, even though there clearly wasn't one? Or seen a meaningful pattern in a random collection of dots or lines? You're not alone: humans are wired to detect patterns and find meaning in a chaotic world.

This phenomenon is called pareidolia, and it's a type of cognitive bias that can have a profound impact on how we perceive and interpret the world around us. In this post, we'll explore what pareidolia is, why it happens, and how you can use it to improve your website's conversion rate.

What is Pareidolia?

At its simplest, pareidolia is the tendency to perceive a specific, often meaningful image in a collection of random or ambiguous data. This can manifest in a variety of ways, from finding faces in clouds to seeing animals in constellations to recognizing religious icons in burnt toast.

Though it may seem like a quirky phenomenon, pareidolia is actually rooted in the way our brains process information. Our brains are wired to detect patterns and make sense of incoming stimuli, and this tendency towards pattern recognition can occasionally lead us astray.

Why Does Pareidolia Happen?

As we mentioned, pareidolia is a byproduct of how our brains process information. The human brain is incredibly adept at identifying patterns and extracting meaning from them, even in situations where there may not be any meaningful patterns to begin with.

This tendency towards pattern recognition is thought to be an evolutionary adaptation that allowed our ancestors to quickly identify threats or opportunities in their environment. By quickly recognizing patterns and making snap judgments based on them, early humans could react quickly to potentially life-threatening situations.

Today, however, this same tendency towards pattern recognition can lead to false positives and inaccurate perceptions. Though pareidolia can be harmless and often amusing, it can also lead to more serious misunderstandings and misinterpretations.

How Can You Use Pareidolia to Improve Your Website's Conversion Rate?

Though pareidolia may seem like an odd quirk of human perception, it can actually be used to great effect by website designers and conversion rate optimization experts. By understanding how pareidolia works, you can create design elements that tap into this natural tendency towards pattern recognition and use it to your benefit.

Some ways you can use pareidolia to improve your website's conversion rate include:

  • Using images that play with ambiguity and encourage users to find hidden meanings or patterns
  • Incorporating hidden design elements that are only visible upon close inspection
  • Designing forms and CTAs that mimic familiar shapes or symbols, making them more memorable and appealing to users

By considering and incorporating the principles of pareidolia into your website design, you can create a more engaging, memorable, and effective user experience.


Pareidolia may seem like a strange, even whimsical phenomenon, but it's actually an important aspect of how our brains process information. By tapping into our natural tendency towards pattern recognition, we can create more engaging, memorable, and effective website designs that help drive conversions and make meaningful connections with our users.

So the next time you find yourself seeing faces in the clouds or recognizing patterns where there may not be any, remember: it's just your brain doing what it's wired to do, and there may be valuable lessons to be learned from this quirky cognitive bias.
