No Time to Think

"There's a time to think, and a time to act. And this, gentlemen, is no time to think. -- Sheriff Bud Boomer, Canadian Bacon"

Any critical choice a character must make quickly through gut instinct instead of logic or knowledge, especially one which would be trivial if not for some incomplete information. Even better if the character is The Spock, and learns An Aesop about trusting other characters, or their own instincts.

This frequently overlaps with, but is not limited to, the Wire Dilemma, where a character needs to disarm a bomb. Spot the Imposter is the version of this trope where a character needs to distinguish an Evil Duplicate from the original.

Examples:

Anime and Manga

 * The second episode of (the remake of) Kujibiki Unbalance.
 * In Pokémon Special, Pearl is very good at making a plan when in the heat of the moment. This is a contrast to Diamond, who's better at figuring things out in the long term.

Comic Books

 * Subverted in Catwoman: One story arc involves the Film Freak trying to set off a nuke in the East End of Gotham. Selina stops it just in time by picking a wire at random and snipping it, explaining to her sidekick Holly, who questions her choice and flinches away when she cuts it, that "They're all the right one. Cutting any wire will shut it down. Don't believe everything you see in the movies, Holly. This is the real world." She's actually wrong: in the actual real world, clipping random wires is a good way to set off a bomb, because dummy wires are the simplest trap a bombmaker can put inside his device with little effort.

Film

 * In the 2007 Transformers movie, . Pretty lucky guess there, Sam!
 * More of a logical leap, as.
 * Definitely a logical leap, when you consider that.
 * By the looks of it, possibly not
 * Conan runs into something like this in Conan the Destroyer. He's reasoned that the wizard he's fighting is behind one of two mirrors, while his friends are behind the other. He rears back to throw his sword, seemingly into the mirror hiding his friends, then turns and throws it at the other mirror, hitting the wizard. It's compelling, until Fridge Logic kicks in, and you wonder why A. none of his friends thought to simply duck, and B. why Conan decided to throw the sword, rather than just walking up to the mirrors and slashing them, as he had been doing.
 * In the film The Abyss, Bud has to disarm a nuclear weapon. He knows it's the red wire, not the blue wire, but in the green monochromatic light of the glowstick, they look the same. Whoops!.
 * In the film Air Force One, President Marshall (played by Harrison Ford) has to cut two wires to drain Air Force One's fuel tanks. The bundle of wires he picks are green, yellow, blue, red and white. He is instructed to cut the green wire but is then cut off. He correctly chooses to cut the yellow wire, saying "I'm counting on you, red, white and blue."

Literature
"Cogitator Ikmenedies: Are there wires leading to the promethium flask?
 * In the Ciaphas Cain novel The Traitor's Hand, Cain foils an assassination attempt, only to discover a bomb built into the aircar used in the ram raid attack. He calls for help from an expert, prompting the following amusing conversation:

Cain: Yes, two.

Ikmenedies: Then it should be simple. All you have to do is cut the red one.

Cain: They're both purple.

Ikemenedies:  You'll just have to use your best judgment."


 * He gets it right, of course.

Live Action TV

 * In the Farscape episode "PK Tech Girl," Crichton explains this trope to a Sebacean woman, who says that her culture has such entertainment as well.
 * Doctor Who example- dealing with a malfunctioning MRI in "Smith and Jones".
 * In Life On Mars Sam crawls under a car to disarm a bomb, but can't remember which wire it's supposed to be.
 * In the season finale of the J Drama Galileo,.
 * In a Stargate SG-1 episode, a meteor is heading towards Earth, but they find out that setting off a nuke to deflect it would only make things worse so they need to deactivate it. However the bomb gets damaged and refuses to shut down so Jack is told to open it and cut the Red wire, so this trope is almost subverted because he is given clear instructions to cut a wire, but here's the kicker - it turns out all the wires are yellow and he has to guess.

Video Games

 * In the intro to the game Discworld II: Mortality Bytes, Rincewind and the Librarian discover a parody of a bomb that uses some sort of bubbling chemical (with an analog timer) attached. Rincewind debates between turning the red flask and turning the blue flask, reasoning that they can't kill him yet since the game hasn't started. He still picks the wrong one, and gets exploded.

Western Animation
"Don't stop! Keep moving! Let your body do the brainwork!"
 * The phrase "Pulling a Homer" (meaning to succeed despite stupidity) was introduced in The Simpsons after Homer stopped a nuclear reactor meltdown by randomly guessing which button activated the Manual Override. Twice. Using Eeny-Meeny-Miney-Moe, no less. To be fair though, if he did the same Eeny-Meeny-Miney-Moe each time he would always get the right button.
 * Donkey Kong Country episode Orangotango has DK navigate three 'Rooms of Doom' in the Temple of Inka Dinka Doo. Said rooms have booby traps, mainly spike and arrows that fly out so quickly that DK has move so quickly he barely knows what he's doing. As Funky put it...

Real Life

 * Real life example: A doctor who didn't know whether to press the orange or blue buttons to restart a bypass machine sustaining a patient's life; news story here.
