The Mandela Effect is a phenomenon where a group of people share false memories of past events which Twitter made popular through claims that these memories are parallel universes spilling into our own.

Fiona Broome is a researcher in the paranormal who takes credit for naming the effect and created the website mandelaeffect.com.

The first proof of the effect was when Broome and many others recalled Nelsen Mandela dying in prison, which did not happen.
This lead other people on Twitter and Reddit to search for more holes in reality, the most common being the title of the Berenstain Bears children book being spelled as Berenstein.

“I too clearly remember it as ‘Berenstein’ even though I never read the books. Why would anyone change that? Seems irrelevant,” said JM, a commenter of Broome’s website.

Proponents of the effect claim that these small instances of mistaken memories show parallel realities.

Broome has said on her website that this effect is not simply false memories or confabulation as top psychologists argue. They claim the brain attempts to fill in memory gaps with false memories which is described as confabulation.

Supporters of Broome and the effect use the certainty of their memories as proof that they are real experiences with no regard to science or well researched facts.

They believe that the brain has the ability to recognize parallel universe shifts and that it doesn’t make mistakes such as misremembering details of the past.

This theory is well documented on the internet where all solid scientific research happens. The people on these forums trust that no one is trolling and try to analyze every tiny detail of the past to yield the truth of our reality and of parallel universes.
