The human stories of mankind's greatest geniuses, like Socrates, Einstein and Stephen Hawking, often include the fact that they were normal, or even sub-normal, in other areas of functioning. Because different humans just have different abilities. Stephen Hawking was of course eventually confined to wheelchair. But he still had a full brilliant career, and that did not stop him from that, or still excelling at his job. And Albert Einstein had a horrible memory it seems. He was a notoriously forgetful person. Nicknamed “The Absent-Minded Professor,” he literally could not remember his own address or phone number. He once boarded a train and could not find his ticket. (Fortunately the conductor recognized Einstein and told him he knew who he was, so he didn't need a ticket.) But we all have different abilities, we are all flawed in some way. And that is what makes us human.
Perhaps it's more insightful to admit that we're all crazy and that people exhibit that craziness in different ways.
Also, you know. People said Einstein was very immature. And he had a horrible memory. He might have had just different intellectual abilities himself. His head, and thus cranial capacity, was very small, an autopsy revealed. And like I said, his memory was atrocious. You know, a while back, they were talking about this man who was suffering from the beginning stages of dementia. And he could still be a medical doctor, they said. But they tested his memory. And it was on the level of a three-year-old by then. Memory, knowledge and math ability. Those are all separate things. And so is maturity, obviously.
Bigger brains doesn't mean clever or intelligent. Educated doesn't mean intelligent. We are all flawed - that's one thing that should bind us as a people. If we accept we're all flawed though in different ways, we might be more achieving in an aim to keep society together. Not leaving people behind and not selfishly focusing on our own supposed success/career. My 2c
