The Mandela Effect is evidence that you may have experienced events from a different reality. Finding others with similar memories can affirm that.

This website is where those conversations started.

Since that start in 2009, the Mandela Effect community has grown to hundreds of thousands of people.

We may have many differences – and different opinions – but what connects us are those extraordinary memories. I believe they’re something to embrace and celebrate.

What is the mandela effect?

The “Mandela Effect” is what happens when someone has a clear memory of something that never happened in this reality.

Many of us – mostly total strangers – remember the exact same events with the exact same details. However, our memories are different from what’s in history books, newspaper archives, and so on.

This isn’t a conspiracy, and we’re not talking about “false memories.” Many of us speculate that parallel realities exist, and – until now – we’ve been “sliding” between them without realizing it.

(Others favor the idea that we’re each enjoying holodeck experiences, possibly with some programming glitches. In my opinion, these aren’t mutually exclusive.)

This website is about real, alternate history and possible explanations for this phenomenon.

Site history – Mandela Effect dot com

Fiona Broome (that’s me) began this website in 2009. Our original conversations were in that grey area between speculation and sci-fi. It was fun. We were talking in “what if…?” terms.

Then, new comments cast the Mandela Effect in a slightly different light. It became more serious.

From there, the topic has taken on a life of its own. You’ll find it discussed at Reddit, YouTube, on TV and radio shows, and across the Internet.


2009: Encouraged by one of my book editors, I started this website. A few people commented. Others emailed me with their insights. Most of the conversations were light, and related to sci-fi concepts and unusual memories.

2010 – 2014: People began reporting memories other than Nelson Mandela’s death in the 20th century. Visitors shared anecdotes and informal theories. Generally, we didn’t take ourselves too seriously.

2015: This topic abruptly reached critical mass. The Berenstein/Berenstain subject went viral, followed by other widespread alternate memories.

Visitors were astonished to learn about others’ memories with astonishingly similar details and points of reference by multiple, unconnected people.

However, a few trolls and spammers joined the discussions. When that was clear, I usually deleted their comments. (Sometimes, I replied, making it clear that I was not amused by their efforts.)

Mostly, I encouraged people to share their own memories and theories. I’ve never felt equipped to decide if someone’s reported memories were true, confusions, or something else.

I’m sure that some “fake” comments appear on this site. That was inevitable, once the topic began to trend.

2016: By mid-2016, moderating comments required six or more hours per day. I didn’t have that kind of free time. (I still don’t.) So, I closed this site to new comments, except for immediate replies to the very newest articles.

Since then, some great websites have provided forums for related discussions. Mandela Effect discussions are in the wild.

2018: I’ve been exploring patterns in the earliest Mandela Effect reports, and — so far — the scant credible (and consistent) data isn’t producing enough useful conclusions. In addition, my professional studies relate to other fields, and occupy most of my workday.

I encourage others to compare notes and see if they find more (and better) Mandela Effect synchronicities and patterns than I have. If you do, please share them with others. This community have a wealth of unanswered questions about this topic.

A little more background

Many years ago, I was one of the people who coined the phrase “Mandela Effect” during a fun, slighly frivolous conversation in Dragon Con‘s “green room.”

(“Shadow,” a Dragon Con security manager, was also part of the conversation. I have no idea which of us started using the phrase, first. And, it’s possible that my husband actually came up with the phrase.)

As an aside, Shadow mentioned that — like me — other people remembered Nelson Mandela’s tragic death in a South African prison, prior to late 2009. (In this reality, Mandela died in 2013.)

Suddenly, several others in the green room joined the conversation. It was a fascinating discussion that spun into weird and hilarious tangents.

After I returned home, one of my book editors encouraged me to start a website about the Mandela Effect, to measure public interest in it.

Since then, this topic has turned into something much bigger. I’m still astonished by that.
