Leveling and Sharpening – when some details fade and others get exaggerated

Electric editorial collage illustrating Leveling and Sharpening

Do you tell a story, and each time it gets more vivid, but some details vanish? That’s Leveling and Sharpening – over time, some details fade while others become exaggerated and overemphasized.

Where it can show up


- Rumors & anecdotes – funny stories get funnier but lose accuracy over time.
- Eyewitness testimony – small details fade, while key moments become more dramatic.
- Personal memories – boring moments are forgotten, while emotional ones grow stronger and more intense.

A practical countermeasure


- Double-check your memories – old notes or photos can help you remember what actually happened.
- Know that retelling changes memory – the more you repeat a story, the more distorted it becomes.
- Don’t unconsciously add drama – the details that feel ‘important’ might just be brain-made exaggerations.
