When a character talks about elf terrorists trying to resurrect an ancient dark lord, the feds call it a "fairy tale." That's in a world full of fairies, as well as centaurs and wands that can literally make anything happen, including resurrecting the dead. Outright dismissing it is like cops in our world laughing off the idea of terrorists sabotaging a nuclear power plant. Maybe that exact thing has never happened, but it definitely could.
My favorite (that is, dumbest) example of this might be in the fourth Transformers movie, Age Of Extinction. At one point, another robot asks Optimus Prime, "You think you were born? No, you were built." So ... wait, Opie didn't know how he was born? It never occurred to him to ask where Transformers come from? If that's the case, then the movie confirmed that Optimus Prime is a virgin who's clueless about the robo-birds and the robo-bees (drones and RC helicopters?). That's a ... very surprising revelation, especially from Michael Bay.
In Fact, They're Constantly Getting Blindsided By This Sort Of Thing
In the theme park of Westworld, the entire draw is its sophisticated robots that are absolutely human in every single way -- appearance, behavior, texture, smell (if you haven't seen the show, yes, the tourists have sex with them nonstop). They are so perfectly lifelike that -- spoiler alert -- it turns out the park's chief engineer was secretly a robot this whole time, and not only did none of his co-workers know, but he didn't know. And yet no one in that universe, at any point, considers that the person they're talking to might secretly be a robot. They're shocked to their very core every time they find out otherwise, as if the very concepts of deception or identity theft don't exist in that society.
Probably twice as weird is the world of Harry Potter, in which there is something called the Polyjuice Potion, which is a magical brew that allows you to transform into any person you wish if you have a piece of their body (a single hair, etc), which an insane psychopath at one point uses to pose as a teacher and infiltrate Hogwarts for an entire year before anybody notices. It is completely undetectable, absolutely anyone can do it (a bunch of kids pull it off at one point), and yet, again, no one is ever paranoid about this happening. There appear to be no routine security measures to verify identity, even in the halls of government.
If you lived in that universe, you'd be checking for this constantly. People would be calling the magic cops the second they noticed someone having magic tuna salad for magic lunch instead of the usual magic egg salad WHICH IS SO UNLIKE THEM. Scammers could show up looking like cops, or your best friend, or mother. Every woman would have to wonder whether she's with her boyfriend or some jealous creep wearing his skin to try to get in her pants. A serial killer would have great success disguising himself as a lost crying toddler in the park -- hell, he could always simply assume the identity of his last victim. And what form of ID would be convincing in a world in which goddamned magic is a thing? Remember, they're mimicking these people right down to their fingerprints. It would be terrifying!
