Memory is something we rely on every single day for nearly every action we take. Without it, we wouldn’t remember how to walk, eat, or even recall our own name. Our history would become completely unclear, and without the framework of our past, we’d be lost in the present, unsure of what was happening. Although memory is essential in our daily lives, we often overlook its importance. There are many misconceptions about how memory functions, and it can trick us in subtle, unexpected ways.
10. Our Memories Shape Our Identity
Many believe that memories are fixed or at least relatively unchanging. This is a common misconception, and for a long time, many experts in the fields of learning and memory held this belief. However, recent studies, especially work by neuroscientist Karim Nader, have shown that memory is far more fluid than we once thought. For many years, the general belief was that once a memory was consolidated—or stored in long-term memory—it couldn't be modified when recalled. The prevailing view was that if you wanted to alter a memory, you needed to intervene early in the encoding stage, before consolidation was complete.
Nader's research and experiments have since proven that this assumption is completely incorrect. Although his fascination with memory started in his youth, it was the events of 9/11 that prompted him to consider how we might alter our memories of the past. He calls these 'flashbulb' memories—vivid recollections of significant events. Many people, for instance, recall watching the first plane crash into the World Trade Center on television on September 11, even though that footage wasn't aired until the following day. This led Nader to question whether memories could be recalled and subtly changed each time we think of them.
Nader's findings revealed that when we recall an event, we go through another phase of encoding—a kind of 'reconsolidation' of the memory. In essence, we have the ability to subtly modify our memories based on how we wish to perceive the world today, helping us make sense of our lives. This means that rather than our present identity being shaped solely by past memories, we often alter those memories to align with how we believe things should be and how we view ourselves now.
9. I Just Need to Commit It to Memory
Rote memorization remains the most widely used method for learning in schools. The process typically involves repeating a phrase, a set of formulas, or similar information over and over until it sticks. Despite its ubiquity among learners and educators, this approach is surprisingly inefficient and unproductive. While it can certainly help embed information into long-term memory, the lack of context makes recall and deeper understanding much harder.
Many students may memorize what they need to know for exams, and this information is indeed stored in their long-term memory. However, they might struggle to recall it later. The issue lies in the context. If a student memorized information through rote learning without connecting it to other course material or using memory techniques, they may find it difficult to retrieve the information when they need it most.
This is why there is ongoing debate in education about whether it's better to focus on memorization or teaching critical thinking and the connection of ideas. Unfortunately, the debate overlooks the real issue: It's not just about memorizing facts, but about how you remember them. If you can relate new information to other concepts in the same class and understand how they interconnect, you'll be much better at recalling it when needed. Additionally, there are many mnemonic techniques that can help create context for improved memory recall.
8. It Will Come Back to Me Later
If you've ever had a brilliant idea or remembered something important only to forget it almost immediately, you might have thought, 'It will come back to me later,' and moved on. Unfortunately, for many people, that memory never does return. The problem here is in how memory works. For something to be stored in long-term memory, it has to go through an encoding process first, which takes time. The more effort and context you put into this process, the more solid the memory becomes. This means if you just learned something, or had a thought for the first time, your brain needs time—and your effort—to properly encode that information into long-term memory.
If the memory you're trying to recall is something you've thought about before, and it’s stored in your long-term memory, it will likely resurface eventually. However, without the right context clues, it might come back to you at an odd time when it doesn't make sense, and you might struggle to recall the circumstances accurately. If the memory is something brand new and you forget it almost immediately, the unfortunate reality is that it’s probably lost for good. It was never truly encoded into your memory.
7. The Accuracy of Eyewitness Testimony
In recent years, psychologists have warned courts and jurors to be highly skeptical of eyewitness testimony. The reason for this is that, as a rule, eyewitness accounts cannot be fully trusted as the sole basis for determining guilt. For instance, the Innocence Project, an organization dedicated to using DNA testing to exonerate the wrongly convicted, has been tracking the causes of wrongful convictions. In over 200 cases, nearly 75% of those falsely convicted ended up in prison due to unreliable eyewitness testimony. Worse yet, many of these cases involved multiple eyewitnesses offering inaccurate reports.
As we discussed earlier, it's easy for us to alter our own memories, and the same is true for eyewitnesses. While their first recollection might be accurate, time and questioning by law enforcement or prosecutors can lead to a distortion of the events. This can result in a version of the truth that’s sincerely believed but ultimately inaccurate, causing confusion in a court of law.
During the 2014 grand jury investigation into whether Darren Wilson should face charges, numerous witnesses provided their testimonies, but none of them had identical accounts. This discrepancy illustrates how memory can be shaped by personal perception, leading to multiple people being completely convinced they saw different things. As a result, eyewitness testimony is often questioned and has become less reliable in court proceedings.
6. Recalling Dreams
Dreams are still a mystery that science has yet to fully unravel. One thing scientists still can’t agree on is the purpose of dreams. While there are numerous theories, none have been definitively proven or universally accepted by the scientific community. Given that we lack a comprehensive understanding of dreams, it's no surprise that we are still uncertain about why we sometimes remember them and other times do not. Interestingly, some believe that recalling dreams is easier when you're in deep sleep, but research suggests the opposite is actually true.
Researchers became intrigued by the fact that some people frequently remember their dreams, while others rarely do. Their studies revealed that individuals who tend to remember their dreams have increased blood flow in specific areas of the brain linked to heightened mental activity during sleep.
It turns out that the brain cannot store new information into long-term memory while you’re in a full sleep. Scientists believe that regular dreamers may be briefly waking up without realizing it, influenced by external stimuli, which gives their partially awake brain the opportunity to transfer elements of the dream into long-term storage. This helps explain why dream recall often consists of short, vague fragments, as the brain only has a brief window to encode these memories into something permanent.
5. Eidetic Memory
One of the most widespread myths about memory is the idea of photographic memory—where a person can recall everything they’ve seen with perfect clarity, as though viewing a film or slideshow. According to science, this ability doesn’t exist. Even individuals with exceptional memory, who can recall images with remarkable detail, still omit or distort some details. While their memory may be incredibly detailed, it is not photographic in nature.
However, there is another phenomenon, often confused with photographic memory, called eidetic imagery. Eidetikers are said to be able to look at an image, and then, even after it is removed, still perceive the image with great detail. Proponents of this ability claim it is much more vivid than an afterimage but not necessarily completely accurate. Research on this phenomenon is limited, and not everyone is convinced it truly exists.
Almost all contemporary studies on the topic were conducted by the Habers, a married couple of researchers who were seeking evidence for eidetic imagery. Unfortunately for those who support this theory, the Habers themselves, in their monograph, express frustration with their methods, admitting that they couldn’t develop objective tests for the phenomenon and acknowledging the shortcomings of their own experiments.
To make matters even worse, those who attempted to replicate the Habers' experiments, and even those who created new ones to objectively test for eidetic imagery, encountered the same issues and criticized the Habers' research methods. Additionally, the Habers consistently claimed that eidetic imagery was only observed in children and that it disappeared as they grew older. However, other researchers studying the phenomenon found that the occurrence of eidetic imagery in children actually increased with age.
4. Negative Memories
Many people believe that positive memories are stronger than negative ones. After all, it seems logical that we would prefer to remember the good moments and forget the bad. However, while some individuals do tend to focus on positive memories, they are in the minority. Negative memories, in fact, tend to stand out more. Although this might seem counterintuitive, there's a rational explanation. When we're happy and content, our brain doesn't have much to process. From an evolutionary perspective, we only need to engage our brains when we’re aiming to achieve something or handling a challenging situation. When we're in a happy state, we’re more relaxed and don’t need to engage as many complex brain processes.
On the other hand, dealing with negative situations requires much more cognitive effort, according to psychologists. This explains why negative situations tend to carry more weight in our minds. Research consistently shows that people are twice as disturbed by negative experiences as they are pleased by positive ones. They also remember negative situations better after they've passed. While this may seem rather bleak, some experts believe that by understanding this tendency, we can manage our emotions more effectively, minimizing the impact of negativity and enhancing the positivity we feel.
3. Our Memory Knows The Difference Between Fantasy And Reality
As previously discussed, even though people often feel confident about their memories, it’s actually quite easy to implant false memories. Additionally, as mentioned earlier in this article, we frequently alter our own memories unintentionally, leading to confusion about what we really did, or didn’t do. However, the studies on implanted memories have mostly been conducted in controlled environments, where ethical concerns prevent researchers from attempting to implant significant or controversial memories. Instead, the experiments typically focus on harmless childhood memories that have no real consequences. Despite this, even when we alter our memories, most of us are convinced that the memories we have of our lives are indeed things that really happened.
Regrettably, we have the ability to accidentally create entirely false memories within our minds without any external influence. This phenomenon, known as "imagination inflation," has been explored in part through Elizabeth Loftus’s studies on false memories. What her research found was that by simply imagining an event, people were more likely to believe it actually occurred. It’s important to note, however, that these experiments focused primarily on imagining childhood memories. Some experts argue that imagination inflation is more likely to happen with childhood memories due to our limited cognitive development at that age, making us more susceptible to the source confusion effect we discussed earlier.
Nonetheless, some contradictions exist within these studies. One study discovered that people were less prone to this memory error if the event was easily plausible, while another study found the opposite result. The researchers were also puzzled by some of their findings because they had anticipated that alerting participants in advance about the experiment would reduce the impact of the effect. Instead, it had little to no effect or, in some cases, actually strengthened the effect, demonstrating that there is still much to learn about how memory works.
2. We Know Where Our Memories Come From
Although we’ve previously mentioned that the accuracy of our memories is often uncertain, most people still believe they can clearly remember where they were when they first recalled something, where they learned it, and from whom or what they learned it. However, it turns out that it’s just as easy to get that wrong too. This is known as "source confusion" in psychological circles. You may have experienced a situation where you shared information with someone, only to later be told that they were the one who originally provided you with that information. If this has happened to you, you likely recall being confused and perhaps even arguing about where you truly learned the information.
This isn’t just about getting the source of a memory wrong—it can lead to more serious issues. When we confuse the origin of our memories, it can interfere with our thinking to such an extent that we might subconsciously form entirely false memories, or at least memories that are partly incorrect. Without the right context to anchor our recollections, the details of what we remember may shift, especially when we’re exposed to additional information from another source. Each time we revisit the memory, it becomes more likely that the details will change further, sometimes without us even realizing it. The clearer and more precise the original memory is, the more likely we are to retain it as it was when we think back on it.
1. Forgetting During Hypnosis
Hypnosis can be categorized into two main types: the theatrical version often seen on stage and the more therapeutic kind practiced in a professional setting. Most people are familiar with the stage version, where a performer invites someone from the audience, typically claiming to select them at random, and has them focus on an object while repeating phrases like "you are getting sleepy." Before long, the volunteer slips into a deep trance, doing outlandish things to entertain the crowd. Afterward, they often report having no memory of the experience, leading to the widespread belief that post-hypnotic amnesia—forgetting everything that occurred under hypnosis—is an inevitable side effect of the process.
In reality, stage hypnosis often involves a number of tricks, including pre-selecting participants from the audience. When performing genuine hypnosis, the hypnotist is carefully choosing those who are particularly susceptible to suggestion. This is because hypnosis cannot make someone do something they absolutely do not want to do, which is why they need willing participants. Forgetting the events that occurred during hypnosis only happens if the subject is given explicit instructions to forget. Moreover, you will only forget if you genuinely want to—no hypnotist can compel you to forget something against your will.
