DeepSummary
In this episode, Dr. Charan Ranganath discusses the science of memory and shares surprising insights about how we recall the past. He explains that memories are not literal recordings but rather constructed in the moment based on bits and pieces of information, often distorted by our current context, beliefs, and the act of retelling. Emotion and attention play a key role in memory formation, with emotionally charged events being more vividly remembered due to the release of chemicals like norepinephrine.
Ranganath also explores why memories can be unreliable in group settings due to interference between different people's recollections and the influence of dominant personalities, making eyewitness testimony often flawed. He delves into how the sense of time passing slowly or quickly is tied to the distinctiveness of our episodic memories, with repetitive experiences like during the pandemic lockdowns making days feel long but weeks pass in a blur.
Towards the end, Ranganath offers tips to improve everyday memory, such as being mindful, limiting distractions, creating visual cues, and diversifying experiences to keep the mind sharp and facilitate creative connections through episodic memory.
Key Episodes Takeaways
- Memories are not literal recordings of the past, but rather constructed in the moment based on bits and pieces of information, often distorted by our current context, beliefs, and the act of retelling memories.
- Emotion and attention play a key role in memory formation, with emotionally charged and distinctive events being more vividly remembered due to the release of chemicals like norepinephrine that promote neural plasticity.
- Memories can be unreliable in group settings due to interference between different people's recollections and the influence of dominant personalities, making eyewitness testimony often flawed.
- The sense of time passing slowly or quickly is tied to the distinctiveness of our episodic memories, with repetitive, non-distinctive experiences during events like the pandemic lockdowns making days feel long but weeks pass in a blur.
- To improve everyday memory, try being mindful, limiting distractions, creating visual cues by vividly imagining reminders, and diversifying experiences to facilitate creative connections through episodic memory.
- Multitasking is detrimental to memory formation and retention, as it leads to fragmented, blurry memories and increased interference.
- Memories can update and change over time, incorporating new information and imagination, which can be beneficial for adapting to changing circumstances but also lead to false memories or delusions if unchecked.
- Episodic memories are tied to specific contexts of people, places, and situations, and retrieving one memory can cue the recall of related episodic memories from the same context, allowing for creative connections and insight.
Top Episodes Quotes
- “Memories are neither false nor true, but constructed in the moment and subject to all of the current moods and biases going on in your brain.“ by Charan Ranganath
- “Multitasking demolishes your memory, and the habit of multitasking demolishes your memory.“ by Charan Ranganath
- “Episodic memories are stored in the brain because it's a coincidence of people, places, and things that were all part of an event that occurred at one place and one time. That is what we call the context, the place and the time and the situation.“ by Charan Ranganath

Forget what you thought you knew about memory! Why We Remember author Charan Ranganath joins us to share surprising insights into how we recall the past.
What We Discuss with Charan Ranganath:
- Memories are not literal recordings of the past, but are constructed in the moment based on bits and pieces of information. We often forget most details, and what we do remember can be distorted by our current context, beliefs, and the act of retelling memories.
- Emotion and attention play a key role in memory formation. Emotionally charged events tend to be remembered more vividly because chemicals like norepinephrine promote neural plasticity. Distinctive, attention-grabbing elements of an experience are more likely to be encoded into long-term memory.
- Memories can be unreliable in group settings due to interference between different people's recollections and the influence of dominant personalities. Eyewitness testimony is often flawed because of how malleable and suggestible human memory is.
- The sense that time is passing slowly or quickly is tied to the distinctiveness of our episodic memories. Repetitive, non-distinctive experiences (like pandemic lockdowns) can make days feel long but weeks pass in a blur due to a lack of memorable event boundaries.
- To improve your everyday memory, try to be mindful and limit distractions in the moment. You can deliberately create memory cues by vividly imagining a visual reminder that will help you recall information later. Diversifying your experiences and learning new things also helps keep your mind sharp and allows you to make creative connections. With some practice, you can harness your episodic memory to enrich your life.
