Forget About It!
In this episode of Hidden Brain, expert Ciara Greene explains why forgetting isn't a flaw in our memory system but rather an essential function that helps us process information effectively. Through everyday examples and research findings, Greene demonstrates how our memories naturally include gaps and changes, and how we tend to remember positive experiences more vividly than negative ones.
The episode explores the relationship between memory and mental well-being through various perspectives, including the case of Jill Price, whose inability to forget became a burden rather than a gift. Greene and host Shankar Vedantam examine how our current emotional state influences which memories we recall, and how memory distortions—including the tendency to remember successes more accurately than failures—affect our self-perception.

1-Page Summary
The Role Of Forgetting In Memory and Cognition
Ciara Greene explains that forgetting isn't a flaw in our memory system but rather a crucial function that helps us prioritize important information. Unlike computers, human memory actively constructs and reconstructs memories, naturally including gaps and changes. Greene illustrates this with everyday examples, such as how we remember breakfast routines by focusing on commonalities rather than specific details.
Interestingly, Greene notes that our memory tends to favor positive experiences over negative ones. She points to research showing how people often misremember negative experiences more positively, such as forgetting the difficulties of pregnancy and childbirth. This selective forgetting, she suggests, might be an evolutionary adaptation that promotes survival and reproduction.
Exceptional Memory Abilities and Their Impacts
Through the case of Jill Price, who possesses extraordinary memory abilities, Greene and Shankar Vedantam demonstrate how the inability to forget can become a burden. Price's condition forces her to remember even the most painful experiences in vivid detail, including her husband's death, making it difficult for her to move forward emotionally.
Greene shares her own experience with a cycling accident to illustrate how persistent memories of trauma can hinder recovery and adaptation. In contrast, Vedantam describes how his vague recollection of a childhood injury demonstrates the beneficial nature of forgetting in maintaining mental well-being.
The Connection Between Memory, Emotion, and Mental Health
Greene reveals how our current emotional state influences which memories we recall - happiness tends to trigger positive memories, while depression brings up negative ones. This connection can create a cycle where negative memories reinforce a gloomy mindset, making it harder to recall positive experiences.
Research conducted by Greene shows that people exhibit a self-serving bias in memory, remembering their successes more accurately than their failures. For instance, students recall their A grades 89% of the time but remember only 29% of their D grades. While this bias might boost self-esteem, it can lead to overconfidence and inaccuracies in self-perception. Greene advocates for approaching our memories with both skepticism and self-compassion, understanding that memory distortions are a natural part of how our minds work.

- Memory actively constructing and reconstructing memories means that our recollections are not exact replicas of past events but are influenced by various factors like emotions, beliefs, and experiences. When we recall a memory, our brain may fill in gaps or alter details based on our current understanding or context. This process can lead to inaccuracies or changes in how we remember events over time, highlighting the dynamic and flexible nature of human memory.
- Selective forgetting as an evolutionary adaptation suggests that our tendency to remember positive experiences more than negative ones may have developed to enhance survival and reproduction. By prioritizing positive memories, individuals may be more motivated to engage in behaviors that increase their chances of success and well-being. This adaptive process could help maintain mental health by reducing the emotional burden of negative experiences, allowing individuals to focus on positive aspects that aid in decision-making and overall functioning.
- Exceptional memory abilities, like those exhibited by individuals such as Jill Price, can become burdensome due to the constant recall of even the most painful experiences in vivid detail. This inability to forget can hinder emotional healing and make it challenging to move forward from traumatic events. The burden lies in the overwhelming nature of remembering every detail, which can lead to emotional distress and difficulty in coping with past experiences. Forgetting plays a crucial role in mental well-being by allowing individuals to selectively recall and process memories, promoting adaptation and emotional resilience.
- Self-serving bias in memory is a cognitive bias where individuals tend to remember and recall past events or information in a way that enhances their self-esteem or self-image. This bias leads people to remember their successes more accurately than their failures, attributing positive outcomes to their own abilities while downplaying or forgetting negative experiences. It can result in overconfidence and inaccuracies in self-perception, as individuals may selectively remember information that portrays them in a favorable light. This bias is a common phenomenon in human memory and can impact how individuals view themselves and their past achievements.
- Approaching memories with skepticism and self-compassion means acknowledging that our memories can be fallible and may not always be completely accurate. It involves questioning the reliability of our recollections while also being kind and understanding towards ourselves when we realize memory distortions or errors. This approach encourages a balanced perspective on our memories, recognizing that they are influenced by various factors and may not always reflect objective reality. By combining skepticism with self-compassion, individuals can navigate the complexities of memory with a critical yet gentle mindset.
Counterarguments
- While forgetting can help prioritize important information, it can also lead to the loss of valuable knowledge and skills that may be important in the future.
- The active construction and reconstruction of memories can sometimes lead to inaccuracies or false memories, which can have serious implications in situations like eyewitness testimony.
- Favoring positive experiences over negative ones might contribute to a lack of preparedness for future challenges, as learning from negative experiences is crucial for personal growth and development.
- The evolutionary perspective on selective forgetting of negative experiences is not universally accepted, and alternative theories suggest that remembering negative experiences can be adaptive by helping to avoid similar negative situations in the future.
- While exceptional memory abilities can be burdensome, they can also provide unique advantages, such as in academic or professional settings where detailed recall is beneficial.
- The idea that forgetting is beneficial for mental well-being does not account for the importance of processing and integrating traumatic memories for psychological healing in some therapeutic contexts.
- The influence of emotional state on memory recall can be more complex, with some research suggesting that people can also recall incongruent memories, such as remembering happy moments during depression.
- The self-serving bias in memory is not always beneficial; it can hinder personal development and the ability to learn from past mistakes.
- Overconfidence due to self-serving bias in memory can lead to poor decision-making and interpersonal conflicts.
- Skepticism towards one's memories can sometimes lead to excessive self-doubt and undermine confidence in one's abilities and experiences.

The Role Of Forgetting In Memory and Cognition
Forgetting Is a Functional Aspect of Memory, Not Merely a Failure
Ciara Greene asserts that forgetting is an intentional function of memory. It's not merely a sign of failure but helps us prioritize important details for living and thriving. Shankar Vedantam introduces the concept and suggests that forgetfulness is not a problem but an integral aspect of cognitive functionality.
Memory Isn't Perfect Like a Computer's
Greene explains that, unlike computers, which store information perfectly, human memory actively constructs and reconstructs memories. This process naturally includes forgetting, and Greene stresses that it’s unrealistic to expect perfect recall. Changes or gaps are normal parts of memory, not necessarily suggestive of dishonesty or concealment.
Efficient Memory: Forgetting Unimportant Details
Greene delves deeper into the efficiency of memory, explaining that forgetting allows the condensing of memories to make mental space not for physical storage but for the accessibility of memories. She uses the example of breakfast routines to show how our memory simplifies information, focusing on commonalities rather than trivial specifics. Precise and perfect recollections are often reconstructed and are not accurate representations of an event.
Forgetting Allows Additional Children After Difficult Experiences
Greene touches upon the positive inclination of memory, where positive events are remembered more clearly over time while negative details are shed. Citing a study, she notes people with lower grades tend to misremember them as higher, reflecting a trait-dependent memory where mutable characteristics are remembered better than those perceived as immutable.

Clarifications
- Trait-dependent memory is a concept where individuals tend to remember mutable characteristics better than those perceived as immutable. This means that people may recall aspects of themselves that they believe can change more vividly than traits they see as fixed. It suggests that memory can be influenced by how flexible or changeable someone perceives certain attributes to be.
- Misremembering or forgetting unpleasant experiences can be seen as an evolutionary advantage because it may help individuals focus on positive aspects, promoting well-being and mental health. This selective memory process could lead to increased resilience and motivation by reducing the emotional impact of negative events. By prioritizing positive memories, individuals may be more inclined to take risks or pursue opportunities, ultimately contributing to their survival and reproductive success. This adaptive mechanism allows individuals to move forward and make decisions without being overly burdened by past negative experiences.
- Systematic distortion or forgetting of negative experiences as an evolutionary adaptation means that our brains may prioritize positive memories over negative ones to help us cope a ...
Counterarguments
- While forgetting may serve functional purposes, it can also lead to negative consequences such as the loss of valuable knowledge or the repetition of past mistakes.
- The comparison between human memory and computer storage might be oversimplified, as some computational models of memory aim to mimic the reconstructive nature of human memory.
- The idea that memory simplifies information could be challenged by instances where individuals remember trivial details very vividly, suggesting that the process of memory simplification is not uniform.
- The assertion that precise recollections are often reconstructed and not accurate may overlook the fact that some individuals have highly accurate and detailed memories, such as those with Highly Superior Autobiographical Memory (HSAM).
- The tendency to remember positive events more clearly could be seen as a bias that distorts personal history, which might have implications for learning from experiences.
- The claim that people misremember negative experiences as less severe might not account for conditions like PTSD, where negative experiences are intensely and persistently remembered.
- The idea that selective forgetting of negative experiences is an evolutionary adaptation could be contested by arguing that ...

Exceptional Memory Abilities and Their Impacts on Individuals
An in-depth discussion reveals that while extraordinary memory abilities may seem advantageous, they can also significantly hinder individuals from overcoming negative experiences and finding balance.
Superpower Becomes Burden When Jill Can't Forget Pain
Shankar Vedantam and Ciara Greene discuss the fictional character Miss Havisham from Charles Dickens' "Great Expectations" and Jill Price, a real person with exceptional memory, to illustrate how being unable to forget can be detrimental. Price's condition means that she can remember even the most painful experiences in excruciating detail, which prevents her from moving on and letting go. This incredible memory, which many may envy, becomes a burden when she relives experiences, particularly negative ones such as the tragic end of her husband's life due to severe diabetes and a stroke.
Price's experiences are not just of sorrow, but of regular life events as well. For example, she still feels a profound sense of disappointment when reminded of missing a field trip in her childhood due to illness. This indicates that her exceptional memory hinders her ability to emotionally move past certain negative experiences.
Exceptional Memory Can Hinder Letting Go Of Negative Experiences and Maintaining Balance
Inability to Forget Hampers Adaptation or Trauma Recovery
Greene shares her own experience of an accident and how the memories of it have stayed with her, exemplifying how an inability to forget can hinder recovery and adaptation. Despite physically recovering enough to ride a bike again, her psychological trauma, heightened anxiety, and vivid memories of the accident have stopped her from returning to cycling, especially for commuting purposes. It even affects her while driving, as she worries about other cyclists’ safety.
Similarly, Jill Price retains every vivid detail of driving to the hospital years after her husband’s death. Her inability to forget not only stops her from moving past the emotional pain but also exhausts her with the inescapable deta ...

The Connection Between Memory, Emotion, and Mental Health
Ciara Greene reveals the intricacies between our recollections, emotions, and our overall mental state, emphasizing the survival advantages of associating with positive memories.
Memories Are Shaped by Emotions; Positives Recalled When Happy, Negatives When Depressed
Greene explains the associative nature of memory, where our current emotional state triggers recollections congruent with that state. Happiness tends to bring forth positive memories, while sadness or depression likely bring up negative ones. This often distorts a person's perception of their life, potentially making it seem more negative than it truly is. There's an implication here that a negative mindset can further hinder the ability to recall positives, thereby perpetuating a depressive cycle.
Negative Cycle: Gloomy Mindset From Negative Memories Hinders Recalling Positives
The discussion hints at the idea that lingering negative memories contribute to psychological issues like depression. A person enduring depression might find it harder to retrieve positive memories but easier to recollect negative events, which reinforces their conviction that their life has been overwhelmingly sad.
Understanding Emotional Bias in Memory Aids People With Depression or Mental Health Issues In Gaining Perspective and Interrupting This Cycle
By acknowledging the emotional bias in memory, individuals with mental health issues may gain perspective and interrupt the negative cycle of memory recall driven by their current emotions. Greene's recounting of Maya Angelou's quote about feelings being more memorable than specifics underscores the depth of this emotional memory bias.
Selective Memory Shapes Our View of Traits and Abilities
Selective memory that filters our traits and abilities further shapes our self-perception.
Self-Serving Bias Boosts Self-Esteem, but May Cause Overconfidence and Inaccuracies
Greene's research indicates a self-serving bias in memory. People more accurately remember their A grades (89%) than their D grades (29%). This cognitive bias leads to overconfidence and inaccuracies, as people tend to think of themselves as better stu ...

Additional Materials
Clarifications
- Memory's associative nature means that our current emotions influence the memories we recall, with positive emotions triggering positive memories and negative emotions bringing up negative ones. This link between emotion and memory can impact our overall mental state and perception of life experiences. Understanding this connection can help individuals with mental health issues gain perspective and interrupt negative memory cycles. By recognizing how emotions shape memory recall, individuals can work towards fostering a healthier mindset and self-perception.
- Emotional bias in memory refers to the phenomenon where our current emotional state influences the types of memories we recall. Positive emotions tend to trigger the recollection of positive memories, while negative emotions can lead to the retrieval of negative memories. This bias can impact our perception of past events and shape our overall mental well-being. Understanding this bias can help individuals with mental health issues gain perspective and interrupt negative memory cycles.
- The self-serving bias in memory is a cognitive tendency where individuals remember positive events about themselves more accurately than negative ones. This bias can lead to overconfidence and inaccuracies in self-perception, as people tend to prioritize and retain memories that enhance their self-esteem. It influences how individuals view their abilities and traits, shaping their overall self-image and confidence levels.
- Cognitive biases in memory are mental shortcuts that influence how we remember information, often leading to distortions or inaccuracies in our recollections. These biases can impact our self-perception, decision-making, and emotional well-being by shaping the way we recall past events and experiences. Understanding these biases can help individuals recognize and address memory distortions, fostering skepticism towards their own memories and promoting self-compassion in the face of forgetfulness. By acknowledging and mitigating cognitive biases in memory, individuals can strive for a more accurate and balanced view of themselves and the world around them.
- Fake memories formed in line with ideological views refer to the phenomenon where individuals may unintentionally create or adopt false memories that align with their existing beliefs or ideologies. This can occur due to cognitive biases and the brain's tendency to fill in gaps in memory with information that fits one's preconceived notions. These false memories can reinforce a person's social identity and str ...
Counterarguments
- While positive memories are often recalled when happy and negative memories when depressed, this is not a universal rule. Some individuals may recall positive memories as a coping mechanism during depression or negative memories during happy times as a form of self-regulation.
- Negative memories can contribute to psychological issues like depression, but it's also important to consider that depression can be caused by a complex interplay of genetic, biological, environmental, and psychological factors beyond memory recall patterns.
- Acknowledging emotional bias in memory can be helpful, but it is not a panacea for mental health issues. Other therapeutic interventions and strategies may be necessary to address the root causes of mental health problems.
- Selective memory does shape self-perception, but it is also influenced by external feedback, social comparisons, and cultural narratives, which can either reinforce or challenge our self-perception.
- Self-serving bias may boost self-esteem, but it can also serve adaptive functions by maintaining motivation and resilience. Overconfidence is not always detrimental and can sometimes lead to positive outcomes through increased ambition and risk-taking. ...
