Of course, reading adult literature requires a lot of life experience that adolescents don't have-- that applies to the adult readership of Asimov as well as Fitzgerald.
Mmm, yeah, but I extrapolated a lot of science from my early SF (and indeed, much later,
Neuromancer encouraged ne to get into IT). I'd be hard pressed to extrapolate deeper human understanding as an adolsecent, and especially from those books, that'd be "boring" and get in the way of 'splosions and stuff. The Lensman books, much as I love 'em, are classics for this. I picked up a hell of a lot about gravity and inertia from them, but sure didn't get how to pick up girls.

The characterisations and social interactions were so much simpler in those books.
Let's take a different approach, referencing a TV show,
Big Bang Theory. It should be asserted that when the guys on BBT go on and on and
on about SFTV and comics, they don't seem to be inclined to explore the ongoing story of the human condition, though as most of us know here, good SF has strong and interesting characters with some depth. For a slightly more fantasy version of this, look at some of the chartacters in the Discworld series, even their depths have depths. The only comment they have in that regards borders on K/S. And before toy say anything about clichés, they are nearly always rooted in a truth,
Those guys read all the books and comics when they were young, you can hear it in a lot of lines (admit it, you say to yourself, "I know this stuff!"). So were those guys smart,
then they read the stuff, or did they read the stuff
then get smart? I'm sorry, there are some guys we all know who could read smart, funny SF 'til the cows came home and they'd
never get it. These are the guys, to extend the cliché a little further, who were usually the jocks who stuffed kids like us in our lockers.*
So what is it, chicken or egg? Read then smart, smart then read?
*In Australia, we don't have lockers, and even at school I was built, as the expression goes, like a brick shithouse, so while there was bullying (due to my docile nature) it wasn't as bad as it could have been. We've never really had the jock/geek mentality going on. Well, not when I went to school, could be different now.
