Misinformation effect theories

There are different theories why the misinformation effect happens, potentially leading to false memories.

1. The original facts and information after the fact get blended together in a person's memory.
2. Misleading information replaces the original memory.
3. Since misleading information is more recent, it's easier to retrieve.
4. The original details may not have been encoded into memory. Misleading information is then mixed into the mental narrative to fill the memory gaps.
