What Is Frequency Illusion?

The Frequency Illusion, also known as the Baader-Meinhof phenomenon, is a cognitive bias that occurs when the thing you've just noticed, experienced, or been told about suddenly crops up constantly. It gives you the feeling that out of nowhere, pretty much everyone is talking about the subject or that it is swiftly surrounding you. For example, you might learn a new word or hear about a particular band for the first time, and then suddenly, you start seeing that word or hearing about that band everywhere. It's not that these things have suddenly become more common; it's just that you've become more aware of them. This phenomenon occurs due to a combination of selective attention and confirmation bias. Selective attention is the process by which our brains focus on certain things while ignoring others, and confirmation bias is the tendency to search for, interpret, and remember information in a way that confirms one's preconceptions. In essence, the Frequency Illusion is a trick our mind plays on us, making us believe that a newly learned or noticed thing is much more prevalent than it actually is. Why Does Frequency Illusion Happen? This phenomenon is very common. It likely affects everyone at some point in their life. Simply put, frequency illusion happens because you pay more attention to things that have recently become important to you. There are two parts to the frequency illusion. First, you’ll believe that something has begun to show up more often. Then, you’ll convince yourself that the word, concept, or other thing didn’t show up as much as it does now, called confirmation bias. The frequency hasn’t actually gone up, but your brain has convinced you that it has. While there aren’t many studies on frequency illusion, the concept is very similar to something called “working memory-driven attentional capture.” This explains how your attention is guided. When you hold a certain idea in your mind, your attention naturally goes toward that thing - without you even noticing. Frequency illusion works with your voluntary and involuntary attention. Voluntary attention helps you select and focus on information that’s important to your current task. Involuntary attention happens when something else captures your attention away from that task.

This is related to how we’ve evolved. Our minds must respond to things around us in order to be safe. But we also need to tune certain things out if we want to effectively complete a task. Attention is important for learning and memory. If you don’t pay attention to something, you won’t remember it. So if you just learned about something new for the first time, chances are that you’ll begin to see it more simply because you’re now aware of it. How Can Frequency Illusion Affect You? For most people, frequency illusion won’t lead to any major effects. It’s simply an interesting phenomenon. But for others, frequency illusion can lead to serious outcomes. For example, if you work within the criminology field, your attention may be brought to a specific suspect. Your mind will then be more inclined to pay attention to that person when new information comes out. This could be helpful to the case and lead a detective to the right suspect. But it can also be harmful. If a detective’s mind is focused on one person, they may miss other key evidence. Similarly, if you work in the medical field, you may have recently learned about a new condition. Because your focus is on this disease, you might be more likely to diagnose more people based on their symptoms. Frequency illusion in this case could be helpful because you’re more aware of this new condition. But it could also cause you to skip over other similar conditions and misdiagnose someone. In other cases, if you have certain psychological disorders, frequency illusion may worsen your condition. If you have schizophrenia, the confirmation bias from frequency illusion can cause you to confirm your own suspicions. If you focus on a specific delusion that you have from schizophrenia, frequency illusion may convince you that something is real when it’s not. Overall, this phenomenon shows you how much information your brain actually takes in at any given moment. Most of the time, you aren’t even aware of it. This concept explains why we notice certain things more than others once our attention is fixated on something.
