What is the Mandela effect?

“There is nothing like returning to a place that remains unchanged to find the ways in which you yourself have altered.” – Nelson Mandela

The Mandela Effect is a term used to describe a curious phenomenon in which many people share the same false memory — recalling an event, detail, or fact that differs from historical records.
The expression was coined in the early 2010s after numerous individuals reported remembering that Nelson Mandela had died in prison during the 1980s, even though he was released in 1990 and later became President of South Africa. The collective certainty of this mistaken memory inspired writer and researcher Fiona Broome to give the phenomenon its name.
Since then, the Mandela Effect has come to represent a broader study of how collective memory works — and sometimes fails. People around the world have reported remembering alternate versions of familiar things: movie quotes that were never said, logos that never existed, book titles that changed, and historical moments that seem to have unfolded differently.
Psychologists often explain the effect as a result of false memory, confabulation, or the way human memory reconstructs information rather than recording it perfectly. Others interpret it as evidence of cultural influence, digital distortion, or even speculative ideas about parallel realities.
At its heart, the Mandela Effect reveals something deeply human: our memories are not just records of the past — they are stories we build together, fragile, shared, and ever-changing.
