Once In A Blue Moon


Memory is a fundamental aspect of human existence, shaping our identities and experiences. Yet, it’s a peculiar facet of our cognitive machinery that memories tend to fade over time, especially when we are not actively reminded of them. This phenomenon raises intriguing questions about the limits and vulnerabilities of human memory. In this article, we explore how quickly we forget people and things when they are not consistently in our thoughts.

The Ebbing Tide of Memory

The human brain is a remarkable organ capable of storing vast amounts of information. However, memory is not a static reservoir but rather a dynamic process. Memories can be categorized into three main types: sensory memory, short-term memory, and long-term memory. It is the long-term memory that concerns us in the context of forgetting.

Psychologists have conducted extensive research on the nature of memory decay. One well-known model, called the “Ebbinghaus forgetting curve,” illustrates how information is rapidly forgotten unless it is reinforced through repetition and rehearsal. Ebbinghaus’s research in the late 19th century showed that we forget about 50% of newly learned information within the first hour and up to 70% within 24 hours if not reviewed.

The Impact of Reminders

Reminders play a crucial role in preserving memories. When we encounter reminders, whether intentionally or serendipitously, they trigger the retrieval of associated memories. For example, seeing a photograph of an old friend can instantly bring back memories of past interactions. Without these triggers, memories gradually recede into the depths of our minds.

People We Forget

  1. Acquaintances: In our fast-paced lives, we encounter numerous individuals – coworkers, neighbors, classmates, or casual acquaintances. If these interactions do not leave a lasting impression or are not reinforced by future encounters, we tend to forget these people surprisingly quickly.
  2. Lost Friends: Friendships may fade when we no longer interact with those friends regularly. The memories we shared can become distant, and the bond weakens unless deliberate efforts are made to maintain the relationship.
  3. Past Loves: Romantic relationships, too, can become distant memories over time. While the intensity of the emotions may diminish, certain experiences and lessons learned can endure.

Things We Forget

  1. Everyday Knowledge: Information like historical facts, scientific concepts, or mathematical formulas may be swiftly forgotten if not regularly used or revisited.
  2. Events and Experiences: Personal experiences, such as vacations, family gatherings, or celebrations, can fade from memory if not actively recalled through photographs or stories.
  3. Skills and Hobbies: Talents and hobbies, like playing a musical instrument or speaking a foreign language, can deteriorate if not practiced regularly.

The Digital Age and Memory

In today’s digital age, our reliance on smartphones and computers has changed the way we remember. With instant access to vast amounts of information, we have outsourced many aspects of memory to technology. We no longer need to remember phone numbers, addresses, or even historical facts because we can easily look them up. This reliance on external devices may be altering the way our brains function, with both benefits and drawbacks.


The speed at which we forget people and things we are not reminded of is a natural part of human cognition. Our brains are selective, holding onto what is deemed most relevant or emotionally significant. While this may seem disheartening at times, it also allows us to adapt and focus on what matters most in our lives.

To combat the inevitable fading of memories, we can take proactive steps to preserve them. By maintaining relationships, revisiting cherished experiences, and consistently practicing skills and knowledge, we can slow down the forgetting process. Additionally, embracing the digital age’s tools for information retrieval can free up mental space for more profound thoughts and creativity.

In essence, while we may forget much over time, it’s the act of remembering that makes our memories truly meaningful and enduring.
