Short answer
The Berenstain Bears Mandela effect is the widespread false memory that the children's book series was spelled "Berenstein." Published books, family statements, and trademarks use Berenstain. Psychologists and fact-checkers explain the mismatch via memory schemas and common "-stein" name patterns - not timeline shifts.
What happened
Common memory
Many people remember "Berenstein Bears" with an "e," often with high confidence from childhood reading or TV.
Documented version
Published books and records use Berenstain, matching creators Stan and Jan Berenstain. Museum finding aids and family interviews affirm that spelling. Editor Theodor Geisel helped popularize the series name banner in the 1960s.
Evidence and mainstream view
Evidence level: E (explained psychological / false-memory case relative to documents). Mainstream consensus: spelling never "switched timelines"; shared misremembering did.

|---|---|
| History changed from Berenstein | Archives show Berenstain |
| TV credits prove Berenstein | Official branding is Berenstain |
| Mandela effect = multiverse proof | Memory science explains shared errors |
