The following are among the most Frequently Asked Questions (FAQs) at this website, with brief answers to resolve those questions.

1. What is the Mandela Effect?

It refers to apparently real, alternate memories of a history that doesn’t match the documented history in this reality.

2. What causes the Mandela Effect?

I haven’t a clue. So far, most people seem to think it’s either a “slide” to an alternate reality, or we’re in a holodeck that’s experiencing a few glitches.

Right now, it’s all speculation. See the Sitemap for my related articles. Also, many of the best answers from this community are in comments at the Theories page. (Those comments will be reorganized for easier reading, later in 2016.)

3. Why are some comments out of order?

This site uses WordPress software. Sometimes, the software lost track of which reply belonged with which comment. And, frequently, people forgot to hit “reply” and just posted a new comment. That’s added at the end of the list on that page.

4. Why don’t you use a forum or a message board?

This was never intended as a social site, though — for a while — it may have looked like one. My goal is to present fresh ideas, insights, and news related to Mandela Effect topics. Sites like Reddit are better designed for focused threads, casual conversations, and social-style comments.

5. Why can’t I add a comment?

Around the middle of April 2016, I closed the site to new comments. See Major Site Changes for more information.

6. What are “markers”?

Short answer: At the moment, we’re using the term broadly. Markers seem to be indications of a reality shift. Other than that, we’re not sure. They could be deliberate signs (sometimes, literally) that indicate access points or portals to other realities. They could be coded messages.
