The Mandela effect refers to the experience of a false memory that many people share. In 2010, researcher Fiona Broome coined the term when she discovered that many people believed, as she did, that anti-apartheid activist Nelson Mandela died in prison in the 1980s. In fact, following his release from prison, Mandela became the president of South Africa and lived until 2013. The Mandela effect can be found in numerous other examples. In cases of the effect, people can be surprised, even defiant, that their memory is wrong. Pick which photograph below you believe is the accurate one.
