Examples: Anime and Manga
- Tetsuo Segawa from Guyver may be the patron saint of Exposition Intuition: thanks to being a science fiction fan, he is able to make numerous, highly specific, and perfectly accurate "guesses" about how the Guyver suit works, the nature of the Zoanoids, that they are being controlled by a major corporation, the various details of the Cronos corporation, the names of individual Zoanoids, and so forth.
- Meme Oshino in Bakemonogatari can always tell what supernatural phenomena affected each girl, usually based on Koyomi's secondhand recounting of their story of their problem.
- In Knowledge is Power Harry and Hermione seem to know what Horcruxes are despite having gone back in time before the events of Harry Potter and the Half-Blood Prince. In fact James and Lily explain it to them in the afterlife, but you could blink and miss it.
- Doctor Forrester in The War Of The Worlds. He's able to deduce how the Martian heat ray works, how the war machines levitate, and even determines based on nothing more than seeing what we do that an alien weapon which causes its victims to light up with X-Ray Sparks then fade to nothing works by "cutting across the lines of electromagnetic force" that holds matter together.
- Samantha Carter in Stargate SG-1 frequently exhibits this trope early in the series, able to deduce the purpose of alien devices and the nature of various supersciences. As the series progresses, she shifts out of this trope and toward a more realistic "Able to exposit on the basis of training and experience".
- This is parodied in the episode "200" with absurdly detailed examples of this trope.
- McKay in Stargate Atlantis often avoids this trope — despite his stated arrogance, he is frequently unwilling to exposit a theory until he has given some piece of technology a thorough examination under laboratory conditions. When circumstances force him to postulate anyway, he's frequently wrong.
- Daniel Jackson does this just as often, with alien cultures and languages instead of science. He spends most of the episode "The First Ones," with an almost-silent alien that doesn't speak English. So naturally, he spends every scene explaining exactly what he thinks is going on, even when he doesn't have his tape-recorder out.
- At the beginning of the final episode of the Doctor Who serial The Armageddon Factor, two characters conveniently recap for us some recent events and the predicament the Doctor is in. Which is strange because these events happened on a different planet and no one present has been in communication with them.
- In a minor example, the kids on Land Of The Lost, who've become fair experts on giant reptilian beasts by this point, are threatened by a two-headed snake in the first episode of season three. Having escaped, they name it "Lu Lu", one "Lu" for each head. How does this fit this trope? It fits, because the two-headed snake's body is completely underwater, out of view, when they run into it. So how did they instantly catch on that it was a multi-headed creature, rather than two big snakes?
- In The Langoliers, Stephen King's Author Avatar author character, played by Dean Stockwell, manages to guess exactly what's happening just by a deserted airport with stale food. Oh, did we mention this guessing includes that they've traveled into the past by going through a circular rainbow, that traveling into the past melts everyone who's not asleep, and that as soon as a time period becomes the past it's devoured by a swarm of temporal monsters? And that they can use the bit of time-space inside their jet to fly back through the circular rainbow to get back to the future? And it works.
- In the Lair of the Shadow Broker DLC for Mass Effect 2, Liara pulls this on the Shadow Broker.
Liara: You're a Yahg, a pre-spaceflight species quarantined to your home-world for massacring the Council's first contact teams. This base is older than your planet's discovery, which means you killed the original Shadow Broker sixty years ago, then took over. I'm guessing you were taken from your world by a trophy hunter who wanted a slave...or a pet. How am I doing?
- She admits to you afterward that she was guessing.
