Have you ever had the experience of learning a new word or phrase, and then suddenly noticing it everywhere? For example, perhaps you learned the word “flummoxed” and then started seeing it used in articles, books, and conversation. If this has happened to you, you may have experienced the Baader-Meinhof phenomenon, also known as the “frequency illusion” (Kruger, 2007). This phenomenon occurs when you become aware of a new word, concept, or phrase and then suddenly notice it repeatedly in the days or weeks following your initial exposure to it (Kruger & Dunning, 1999).
The Baader-Meinhof phenomenon can be especially helpful in learning math through rote. When you encounter a new math concept repeatedly, it helps to reinforce the information in your memory and make it easier to recall (Kruger & Dunning, 1999). This is particularly useful for math concepts that are best learned through repetition and practice, such as basic arithmetic operations or memorizing formulas. By actively seeking out opportunities to practice and apply what you have learned, you can help your brain filter and retain the information more effectively (Dunning et al., 2003).
However, it’s important to keep in mind that the Baader-Meinhof phenomenon is a common experience and does not always occur (Kruger, 2007). It is not uncommon for people to learn about new things and not encounter them frequently in the days or weeks following their initial exposure (Kruger & Dunning, 1999). Additionally, the frequency with which people encounter new information can depend on a variety of factors, such as their environment, the media they consume, and the people they interact with (Dunning et al., 2003).
So the next time you find yourself suddenly encountering a math concept you recently learned, don’t be surprised – it may just be the Baader-Meinhof phenomenon at work! And if you want to make the most of this phenomenon and learn math through rote, try repeating and practicing the concepts regularly (Kruger, 2007). This can help you strengthen the connections in your brain and make it easier for your brain to notice and retain related material.
