The Science of Forgetting: Why We're Already Losing Our Pandemic Memories and the Potential of Memory as a Service

In a world filled with constant information overload, it's no surprise that our memories often fail us. According to cognitive psychology professor Norman Brown, forgetting is the default mode of our brains. However, understanding the science behind memory can shed light on why we forget and how we can potentially improve our recollection.

Memory is a multi-phase process that involves encoding, consolidation, and retrieval of information. When we encounter new information, our brains encode it through changes in neurons in the hippocampus, a crucial memory center. These neurons create a physical memory trace known as an engram. Unfortunately, much of this information is lost unless it goes through memory consolidation, which often occurs during sleep. Consolidation helps stabilize and store memories for the long term.

During memory retrieval, the memory trace neurons in the hippocampus and cortex are reactivated. Our memories are centered around our life stories and the events that personally affected us the most. However, even salient emotional and life-threatening events can be difficult to capture fully. The more memories we accumulate, the harder it becomes to remember all of them. New memories, resulting from the simple act of living, interfere with the recall of older events.

Additionally, the saliency and personal impact of an event affect its memorability. New events are more likely to be remembered because we tend to talk about them and rehearse them repeatedly, reinforcing their memory traces. On the other hand, uniform events are harder to recall as the memory tends to consolidate them into one vague recollection.

As a society, many people may not want to hold onto their memories of the COVID-19 pandemic. Humans have a natural tendency to view the future more positively than the past. The future offers countless possibilities, while the past is fixed. When we remember the past, we do so in the present, influenced by our current emotions, knowledge, and attitudes. This bias towards future-oriented positivity may impact how we reflect on the pandemic and approach the future.

To truly preserve our autobiographical memories as part of history, they need to be transformed by the collective experience. History requires our individual stories to be turned on their heads, transcending personal recollections. While parents pass down their knowledge and family history to future generations, these communicative memories tend to fade after two or three generations. Without cultural artifacts like books, movies, statues, and museums, the memories of the COVID-19 pandemic may also be consigned to the entropic dustbin of history.

However, there is potential for technology to play a role in improving human memory. The concept of "Memory as a Service" suggests using technology to enhance our ability to remember and make better sense of the information we already have. This could be achieved through applications that integrate with web browsers, mobile phones, desktop operating systems, and various other services. By pooling and indexing memories from multiple sources, we could potentially enhance our recollection capabilities.

While Memory as a Service holds promise, its ideal implementation is still to be determined. The idea of collecting and indexing all memories may raise privacy and security concerns. Thoughtful approaches would be necessary to ensure user comfort and protect sensitive information. However, the market for such a service could be enormous, benefiting not only knowledge workers but anyone seeking to improve their memory.

In conclusion, the science of forgetting teaches us that memory is a complex process, prone to various factors that lead to its deterioration. Understanding the mechanisms behind memory encoding, consolidation, and retrieval can shed light on why we forget and how we can potentially improve our recollection. Additionally, the concept of Memory as a Service offers an intriguing possibility for leveraging technology to enhance our memory capabilities. By integrating memories from multiple sources, we can create a more comprehensive and accessible repository of personal and collective knowledge.

Three actionable advice:

1. Practice active recall and retrieval: Engage in activities that challenge your memory, such as quizzes, puzzles, or recounting events from memory. Actively retrieving information strengthens neural connections and improves memory retention.
2. Get enough sleep: Sleep plays a vital role in memory consolidation. Prioritize a good night's sleep to enhance your brain's ability to store and retrieve information effectively.
3. Utilize external memory aids: Leverage technology and tools to offload some of your memory burdens. Use note-taking apps, calendars, and reminders to store and retrieve information when needed.

Whether it's the fading memories of the pandemic or our struggles to remember everyday details, understanding the science behind memory can help us navigate the complexities of our cognitive abilities. By embracing new technologies and incorporating memory-enhancing practices into our lives, we can strive for a better understanding of the past and a more vibrant recollection of the future.
