Imagine sitting beside a big horse nerd and every time a horse is on the screen and makes this typical horse noise they would comment "the horse didn't make the sound" or white walkers are killing the night watch behind the wall and "this horse is not really frightened but relaxed and listens curiously" or every time there is a mighty black Frisian horse in a movie, which believe me hey are a lot!, they would comment how wrong and stupid it is that Zorro/Prince of Persia/the Spartans are riding Frisians.
Of course now he's got me doing it too...
The slide just never seems to lock back like it should unless the hero has two guns that need to be thrown on the ground before he/she walks forward defiantly and grabs two MORE guns.

They're not reporting fact. They're weaving a fantasy.
Whatever your field is, if you want to got stark raving mad, watch a movie made about it.
At the very least, the people writing, acting, and directing your world have little or no idea of what it's really like. And even if they do, they're taking deliberate liberties to embellish or interpret the realm to make it more telegenic.
An interesting exception: movies looking in on themselves -- at movies, TV, and entertainment. There's frequently embellishment, still (people and events are more glamorous / beautiful / hip than they are in reality), but there's often a lot of real insight.
Best example in a field I'm familiar with - "Strictly Ballroom". Sure, everybody was over the top, but anybody who was ever involved in competitive ballroom dancing will recognize all the archetypes and be able to relate to the various things said about dancers.
For some reason, it's easier to swallow that characters are exaggerated, instead of facts. (This being HN, I fully expect a reply within the next 15 minutes explaining the exact psychological effect, complete with links to relevant papers ;)

But really, nobody ever says things like "I need a dedicated Linux box running Apache with a MySQL back end" outside of an Aaron Sorkin script.
When all else fails, make shit up.
