I must be stuck in only one reality because I remembered all those accurately. I find it odd that people don't remember Volvo's logo has a male symbol because that seems distinctive.
What's interesting to me is that remembering inaccurately in specific ways is a group characteristic, and not just the product of isolated individuals. This should not be surprising. The logo of something or the spelling of something may be close enough to a commonly understood or perceived counterpart. People would tend to gravitate toward the more familiar of the two, and perceive both as the more familiar.
I've never actually heard of the Berenstein Bears, but to read "Berenstein" correctly jars my brain. To even pronounce it correctly jars my brain. I have this flag go up that says, "No, no. This is wrong." So my brain intercedes and fixes the problem for me subconsciously, and stores it away. When I pull it up later, I'm going to remember it wrong, apparently with a whole bunch of other people, and a conspiracy of sorts begins suggesting that someone has changed it since it was first introduced.
It reminds me of the seductive quality of logical fallacies. It's easy to understand why a logical fallacy is wrong, but they are so universally appealing in the right circumstances that people automatically use them without closely examining how they are being incorrectly applied. And they are so universally appealing that over the years experts in logic have identified them and actually named them. Talk about universal appeal.
It's the curse of homo sapiens, one of the first species to have evolved a uniquely cognitive brain. It's a good brain as brains go, and everyone wants one, but geologically speaking, it just hit the market and is fraught with design errors, and it's going to take a long time to perfect.
