Misinformation Effect – when false details alter your memories
Do you swear you saw something at an event, even though it wasn’t there? That’s Misinformation Effect – when memory becomes less accurate due to false details added later.
Where it can show up
- Eyewitness testimony – if someone says the suspect wore a red jacket, you might ‘remember’ it that way, even if it was blue.
- Historical events – movies, books, and discussions can ‘rewrite’ how you recall real events.
- Personal memories – friends’ stories might change how you remember your own experiences.
A practical countermeasure
- Write down key events immediately – this helps preserve them accurately.
- Be cautious with repeated stories – the more you hear something, the more likely you’ll ‘remember’ it.
- Double-check sources – if something feels unclear, verify the facts.
