The discussion centers on whether a writer who is not a genius can convincingly create a genius character. It highlights that writing does not require the author to possess the same level of intelligence as their characters. Authors can portray genius through compelling narratives and character development, even if they lack expertise in the character's field. The conversation references Sherlock Holmes and his reliance on outdated pseudoscience, suggesting that even celebrated characters can exhibit flaws in logic. The ability to depict genius relies on the author's skill in crafting believable scenarios and character insights, rather than their own intellectual prowess. The discussion also touches on the challenges of convincing modern readers of a character's genius, especially when outdated or nonsensical reasoning is involved. Ultimately, the consensus is that a bright author can create a genius character by effectively engaging the reader's imagination and presenting the character's thought processes in a relatable manner.
