On that note, I'd argue that most of the literature consumed by the well-read characters (Rory and Jess, particularly) wasn't especially challenging. It was mostly the well-known big hitters of literature, not anything particularly unique, subversive, or diverse. Did we ever see Rory read many books by non-white authors, or off beat, unique or obscure literature? I feel like her choices were mostly very safe and WASPy. So, to be honest, I wouldn't say Dean's choices in literature said anything about his intelligence, just because he didn't read Tolstoy or Austin (who I don't see as especially challenging writers and I don't think it says much about Rory's intelligence for reading them).
Yeah, Dean had pretty impressive mechanical skills. There is more then one way to be gifted or intelligent, and in the real world, Dean could've become a mechanical engineer. But in ASP's world, if you aren't a college bound reader and incredibly quick-witted and make obscure pop culture references, you are a moronic loser. Unless you own a quirky business, of course.🙄
