What concept is frequently cited to explain the shared, incorrect memory of being in the Sagittarius Arm?

Answer

Mandela Effect

The widespread divergence where a large group shares the specific, yet factually incorrect, memory of the Sun residing in the Sagittarius Arm is frequently cited as a prime example of the Mandela Effect. This phenomenon describes collective false memory concerning historical or factual details. The contrast between the objective astronomical fact—our residence in the small Local Arm—and this deeply held, shared misrecollection makes this specific geographical shift a compelling case study for this effect.
