The Mandela Effect: When Many People Remember the Same Past but Today’s Record Says Something Else

In 2009, Fiona Broome said she met many people who believed Nelson Mandela had died in prison in South Africa during the 1980s. They did not remember a single line of news. They remembered television coverage, a funeral, remarks from his wife, and the feeling that they had known the event for years. Yet Mandela was released in 1990, became South Africa’s president in 1994, and died in 2013. The gap between detailed memories held by many people and the record preserved in archives gave the phenomenon its name: the Mandela Effect.

More examples followed. Many people remember the Monopoly character wearing a monocle even though the official image has none. They remember Pikachu with a black tail tip even though the familiar design has brown only at the base of the tail. They remember Berenstein Bears rather than Berenstain Bears. They remember “Luke, I am your father” even though Star Wars says “No, I am your father.” One mistaken memory would be a small story. What catches believers’ attention is that unrelated people remember the same detail in the same direction and often say they are completely certain.
