Two weeks ago Jim described a vivid, flashbulb memory from his childhood of the day he found out that his parents won the lottery. He remembered exactly where he was sitting in his house and what board game he and his siblings were playing when they head the news. He even recalled the score of the game.

Recently Jim discovered that he was completely wrong about his recall of that day. How would you explain his inaccurate memory of this experience?
