There appears to be a growing amount of people who are becoming aware of the Mandela Effect.... whether it's The Berenstain/Berenstein spelling controversy, the death of Billy Graham, 4 people in the car during JFK assassination or Kurt Kobains missing pink jacket, people are becoming curious about the phenomenon.

As for me, I am 100% sure that Dolly wore braces in Moonraker. My brother and cousin also share my conviction.

Anyway, my question is this;

What do you believe is causing The Mandela Effect?
