Why We Remember Bad Memories Better Than Happy Memories
“We Tend to Recall Bad Memories More Than Happy Memories, According to Science”
If you were asked to think back to the last time you felt extremely happy and couldn’t help but smile, versus the last time you went through a difficult time, which would come to mind first?
It’s common for us to give more space in our memories to negative events than to good times. One study found that we can recall more bad memories and more details than good ones.
It depends on the emotion behind the memory and how it triggers brain activity, often at the cost of distortion.
Here’s a scientific explanation for why this is happening.
Bad Memories Last Longer
It may seem obvious that scary or abnormal memories stay in our minds longer than happy ones, but understanding why is crucial to learning to value and prioritize good memories.
Researchers at Tulane University explain that the brain is responsible for processing emotions, like the amygdala and frontal cortex, which are highly stimulated during negative events.
This intense stimulation leads to a particular form of memory, recording the details of negative events with remarkable precision. In contrast, positive events are often less detailed and less deeply ingrained in our memory.
Negative Events Are Better Remembered
When you close your eyes, you are more likely to vividly relive negative memories than happy ones. Studies show that people remember details related to negative events more accurately, while happy memories tend to be vaguer.
This is because negative memories trigger a fight-or-flight response, focusing the brain only on details that are perceived as threatening, such as a weapon rather than the person holding it.
The Brain Center Is Awakened
When an unpleasant event occurs, your body goes into a fight-or-flight state, causing your brain to become overstimulated.
This overstimulation changes your brainwave frequency from a resting state to a heightened state of arousal, which contributes to the creation of bad memories. This response is linked to the release of stress neurotransmitters, such as norepinephrine, which make negative memories more vivid.
An Adrenaline Rush On Bad Memories
Jeffrey Tasker, a professor of cellular and molecular biology at Tulane, explains that frightening memories are often accompanied by an adrenaline rush: “When you’re threatened with a weapon, your brain releases norepinephrine, which causes a response similar to an adrenaline rush.”
This release of neurotransmitters increases the memory of negative details. In contrast, happy memories are often less marked by such an emotional response, making them more prone to memory errors.
An Emotional Response
We remember emotions more than specific events. Although we are not always consciously aware of the information we process and store, our emotional state strongly influences our memory.
Emotional memories are often more vivid, but they can also be subject to distortion. For example, you might feel bad without immediately understanding why because a bad memory could influence your current emotional state.
Bad Memories
It’s Based on Evolution
This phenomenon is rooted in evolution. Historically, the ability to remember threats and dangers has been crucial for survival. Bad memories help us avoid dangerous situations and pass this knowledge down through generations. This evolutionary mechanism allows us to remember threatening events with increased accuracy to avoid future dangers.
Bad Memory Errors Preserve Meaningful Moments
Despite their importance, memories are not perfect. They can become inconsistent, altered, or forgotten over time. As William James wrote, “Some events are so emotional that they leave a scar on the brain tissue.” Memories, while protective, can be exaggerated or distorted. It is essential to recognize that memories, while important, are not always accurate.
Memories Change Over Time
Memories change over time. The details of a memory can change depending on your current state, the people around you, and the time that has passed. For example, a breakup that seemed devastating may seem insignificant over time. Emotional memories are subjective and can be influenced by various external factors.
We Expect the Worst
We tend to prepare for the worst, thinking that this will make us more resilient in the face of difficulties. However, this constant anticipation of the worst can reinforce negative events in our memory and influence our perception of reality. By believing that bad things are more likely to happen, we attract them and give them disproportionate importance.
Conclusion
Although bad memories are often more persistent and detailed, they can be managed and transformed. By learning to control and reprogram our memories, we can better balance the negative and positive aspects of our lives.
We have the power to choose how we react to memories and decide how they influence our future.
