“Mandela effect”, popularized phenomenon in which a group of people collectively misremember facts, events, or other details in a consistent manner. Paranormal researcher and author Fiona Broome conceptualized the effect after discovering that she and others possessed strong, yet false, memories about the death of South African anti-apartheid activist (and later president) Nelson Mandela while in prison during the 1980s. Research has found evidence for a specific Mandela effect concerning the misidentification of certain pop culture images; however, intense debate has occurred over potential causal mechanisms, many of which include pseudoscientific explanations.” – “Mandela Effect.” Encyclopaedia Britannica, Encyclopaedia Britannica, Inc.
