Mandela effect is legitimately just proof at how out of control the ego-product of society is. 
A few people remember something wrong and assume that the universe has changed because they assume their memory is 100% at all times. Have an incorrect memory? Sure as hell isn't your natural human flaws, you're perfect, must be that the universe has a skip. That's somehow more reasonable.

Good grief...

It's not about bad memory or ego, it's about thought forms being shared by large groups of people. I don't understand how people are so obtuse about ME's but hang out on 4channel where every other thread is about some new form of propaganda subverting our thought processes and culture. If anything ME's are demonstrable proof that inception-like methods can work and are at least worth taking a look at to better understand how the public zeitgeist can be manipulated. But I'm sure certain people wouldn't want that, right?
