I think a lot of these "effects" are just due to popular culture getting things a little big wrong, or bending them to be a more catchy phrase and the rest of us not being a subject matter expert enough to get it. (Wait, wait, stay with me til the end on this.)
Example: "Luke, I am your father" works a lot better as a stand alone reference than "No, I am your father" because people immediately get that you're talking about star wars.. vs just being creepy about your paternity.
Some also come from your brain quickly learning things in passing and making a little bit of a logical leap.
Example: I bet everyone of us learned about immigrants coming to the US, seeing the statue of liberty, and then landing at Ellis island to be processed. The focus of the story is immigrants and Ellis island, and there's a chance that when you learned about it, the name of the island that the actual statue of liberty was on was never mentioned. So then later when someone askes you what island the statue of liberty is on, your brain just associates it with Ellis island because those two things have been remembered hand in hand since the beginning.
Then there's some that might just not have been clear. I clearly remember the BerenSTEIN bears, but I was little, the font was in cursive, and we've got people out there even saying it was BEARenSTEIN bears, so there could have just been parents and teachers and whatnot pronouncing it badly and not caring.
So yeah, you can look at some of these effects and sort of figure out why people would have a different notion about it. but there are others that really bother me.
Nelson Mandela Himself- I swear up and down that I heard about his death on the radio while riding home from soccer practice with my mom. We even talked about it. Not sure how or where my brain could have mixed that up. I've heard some people say people could be mixing him up for Steve Biko(another dude who died in prison in South Africa), but that happened before I was born and I had never heard of that guy before that theory.
Fruit of the loom- I remember the Cornucopia. I can't explain where I could have made that logical leap to add it, since there's only fruit and textile manufacturing mentioned in the name of the product, and really a cornucopia isn't something that I commonly saw or thought of in my childhood.
There are a few others. Enough to give make me think twice.
So if the multi-universe theory is correct, does that mean anyone who doesn't remember things the other way didn't exist in our old universe? or they didn't get replaced or?
