The Mandela Effect was discovered by an adult reading a children’s book. Their name has been lost to time, but the book was one in The Berenstain Bears series by Stan and Jan Berenstain. They are about a gender normative family of bears that live in a tree and may or may not be farmers of some sort. They are vaguely Christian but not in a “We’ve read and understand the bible” kind of way. They’re very relatable to many Americans.
