We’ve all read those Isekai mangas... or at least I have... but how realistic would they really be put into practice?
Say a normal average dude suddenly gets caught in some weird temporal event that sends his mind back in time to his five year old body. He is nothing special intelligence wise, but he’s also not stupid. He did well in high school, and went to college for something science based and graduated in the top five of his class. He’s smart, but not in any inherent way, rather just from hard work.
- How much of his memories and knowledge could his brain feasibly retain? I’ve read that children’s brains are like sponges, but that they also are still developing so might not have the capacity to retain a whole life’s worth of memories? Also, he was not a genius child growing up, so his brain would not look like the brain of a gifted child which could affect things, especially considering:
When analyzing the working memories of the prodigies, scientists came across an amazing result. Each of the eight prodigies had a working memory which put them in the top 1% of the population and each of them made it to the top 99th percentile in terms of working memory capacity.
Additionally, I’d assume there would be psychological issues that would stem from such an extreme influx of information to the brain. Perhaps the brain would simply lock away parts of his memory or knowledge until he’s older and his brain is more able to deal with it? I’m not really sure if there’s anything comparable in real life to this sort of ‘brain info dump’ but it would surely be comparable to traumatic events in childhood being forcibly forgotten.
- Dependent on the answer to 1, how much of a genius would he be considered? It’s not like he has any increased ability, but rather that he just already knew more than a child ever would. So once he reaches the limit of said knowledge would he cease being considered a genius?
