Differences in Genres

When comparing what we've been reading in class to what I normally read on my own time, I've noticed there's a lot of differences. Normally I read fiction books, they tend to be romance or mysteries. There's really no research in these books. I'm sure the author did a lot of research to find out how the certain characters act and how they do their jobs but it's not the same as Gladwell's research. In The Tipping Point Gladwell uses research to back up pretty much every example he gives. He's interviewed college students and made up tests that help him decide what to write. In my kind of books the authors write what they feel, not what they can back up so that separates these books greatly. The style of writing is very different as well because in my books the style is very informal, but in Gladwell's book he's trying to teach us something so the style is much more formal.
