It sounds far fetched at first, but I think it could be true. There was a time in my life when I read literature constantly and started using those patterns in my writing. The habit fell off quickly after I stopped reading for a while, so there might be hope.
The amount of trivia that you must handle to be able to understand the latest movie is mind boggling. Disney should do education, because I would need to watch and study all the previous movies, which is probably a year worth of work, before I can watch subsequent releases. Perhaps not as hard work as studying linear algebra, perhaps, but
still a lot of person hours involved.
The amount of information that the average fan retains about Star Wars is mind boggling, compared to their, say, knowledge of world geography.
I am also in awe of sports fans in a similar way. They command large swaths of dry, boring information such as world series stats with great enthusiasm.
