When unraveling a mystery or trying to push the plot along, a character may come to an affirmative conclusion through deductive reasoning, even though the rationale behind it feels like a mental Wiki Walk that has little basis in the information as presented. This conclusion is often shockingly accurate despite lacking a naturalistic revelation, since the writer just needs to move the story along. Can also be interpreted as "batshit crazy deduction."
Often used in cases where the viewers already know that everything's connected and how they connect, but there's no in-story explanation, and the plot really needs to get to the next part. There's also the matter that since most authors are not themselves genius detectives, in many cases they have trouble thinking of a good way for the character to figure out connections that the author has already decided will exist.
Detective novelist Ronald A. Knox discouraged the use of this in his rules for a Fair-Play Whodunnit.
Consider too that sometimes the insanity of the train of thought may be required when dealing with someone who has their own unique viewpoint. In this situation it is not a matter of determining a clean and coherent legal case to back up your claims, but seeking to understand the mindset of the person who created the mystery in the first place.
The Trope Namer is Batman, specifically the '60s Adam West Batman, who, given his title as the World's Greatest Detective, can easily fall into this when a writer gets into a rut (or is playing it up for laughs). When up against criminal masterminds such as the Joker or the Complexity Addiction of The Riddler he would often rely on insane rationale or some oddly perfect analysis tool to figure out the next step in the scheme.
Compare the following tropes:
Conviction by Contradiction: A fact stated by the accused that is revealed to be mistaken, no matter how minor, be it a single second off in the time they say they did something in their alibi or talking about the deceased in the past tense allegedly too soon after they died, is portrayed as "the clue"
Conviction by Counterfactual Clue — the conclusion is based on faulty deduction and false or unreliable facts, which would not be legally valid
Clue, Evidence, and a Smoking Gun — the last clue is a Smoking Gun, making the previous ones redundant
Entertainingly Wrong — the facts and logic are broadly correct but the conclusion is way off the mark
"Eureka!" Moment — the deductive leap is instigated by something unrelated, but is merely the catalyst for the missing piece and not vital to the logic itself
Insane Troll Logic — the "deduction" is an excuse to reach a pre-desired conclusion
Right for the Wrong Reasons — the conclusion is correct but the logic or facts are mistaken
Also see Only the Author Can Save Them Now. This is a natural result of having Super-Intelligence. Epileptic Trees are fan theories that look like this, and the Conspiracy Theorist is frequently someone who thinks they have pulled off the equivalent of a Bat Deduction that proves their beliefs. Gambit Roulette is the plan equivalent.

Izuku in Deku? I think he's some pro... determines the existence of One For All because of a Master-Apprentice Chain where each member suddenly gained Super-Strength. Fair enough. But he also somehow determines that One For All stockpiles not just raw power, but also the Quirks of the previous holders, even though none of them ever manifested any of the others' Quirks. When Mirio is manifesting Blackwhip for the first time, Izuku is notably confused that the older boy didn't expect such a thing. He's later upset with All Might for not telling Mirio that One For All stockpiled Quirks, even though there was literally no reason to even suspect it could do so.

In Worm, Tattletale has the ability to draw correct conclusions from a seemingly impossibly small amount of data as an actual superpower. Although she can still get things wrong if she tries to figure out too much from too little, and can get swept on divergent trains of thought if not careful.

The 1966-68 Batman series made liberal use of this, as the various villains would usually leave clues for the World's Greatest Detective, and the correct solution almost always required Bat Deductions. This turned up pretty often with The Riddler.
Once, Batman solved one of the Riddler's riddles that wasn't even spoken or written. Riddler used a wax-based solvent to dissolve a hole through the wall of a vault, and on doing a forensic investigation of the crime scene, Batman's chemical analysis revealed it to contain Nitrogen, Uranium, and Sodium:
The series was so aware that it was going to rely on this sort of thing that invoking the trope formed the backbone of the plot of the very third episode. The Penguin, being out of ideas for a heist, sends a random umbrella to Batman. His plan: Batman will analyze the "clue", use Bat Deduction to figure out what the Penguin is planning, and the Penguin will hear it through the radio transmitter hidden in the umbrella, and then go and commit that crime! A brilliant inversion, lampshading, and subversion all in one.
Batgirl once deduced the plot of an episode based on the fact that her father was late getting home and that a new singer was in town. The episode was meant to be connected to the previous one, where she had met the villain and guesses her cover is that of the singer.

Parodied in an Oink! strip. When the villainous Puzzler leaves a note that says "I'm going to rob the bank in the high street. Yours sincerely, The Puzzler". Rubbishman and Boy Blunder deduce from this that water voles live in river banks, Rob is short for Robert and the highest street in the world is in Tibet: therefore The Puzzler has trained a water vole named Robert to do something unspeakable in Tibet. They spend two weeks in Tibet, but all they find is a fruit bat called Kevin. While they are away, the Puzzler robs the bank in the high street.

TheRealJims's video "Who REALLY Shot Mr. Burns? (Part 1)" discusses The Simpsons two-part episode "Who Shot Mr. Burns?" and how well the solution that Maggie shot Mr. Burns works, arguing that the weakness with the solution is its dependence on symbolism, saying "Symbolism is not evidence, it's just a writing device. You cannot go to your local police station and explain because it was raining during a recent murder, that the murderer must be the man selling umbrellas. They will look at you funny, and probably arrest you.". He would subsequently make more videos proposing alternate solutions that either Marge, Lisa, Bart, Grampa, and Homer shot Mr. Burns, instead, which would still tie into the foreshadowing from Part 1 and the show's canon.

In an episode of Bones, Brennan deduces that the murder weapon must be The Slaughter's Chalice, a famous goblet that's been lost for centuries. She discovers this because there's traces of precious stones on the body. What makes it especially bad is that the traces contain diamond dust, which even she admits is not part of the chalice, meaning she cherry-picked which evidence to include in this deduction. Brennan, who won't speculate that sharp force trauma to the sternum indicates murder. The only thing that lends the slightest amount of credence to her idea is the fact that one of the suspects is known to be a collector of ancient artifacts, but the chalice wasn't even brought up before this point.

Some of House's deductions are quite a reach. In "Pilot," the patient of the week turns out to have tapeworms in her brain, which House figures out because she has ham in her fridge. He doesn't test the ham in any way; he just thinks ham = pork = tapeworms and turns out to be right. And he calls Foreman an idiot because he hadn't mentioned the ham, thinking it irrelevant.

Miraculous Ladybug:
"Sapotis": In the original French dub, Ladybug gets a teapot as her Lucky Charm and somehow deduces that she has to go to Master Fu for assistance when Chat Noir makes a comment about being too young to drink tea. In the English dub, Chat Noir's line is changed to a comment about his kung-fu getting rusty, making Ladybug's deduction more plausible and thus averting this trope.
"Passion": Played with. Mister Bug's Lucky Charm is a perfume bottle, which he connects to Gabriel Agreste's house based on a perfume advertisement that lands right next to him. Lady Noire thinks it's a reach, but he asks her to trust him, since she has often drawn similar conclusions from seemingly flimsy evidence. In reality, he has already deduced where the akuma is, and the Lucky Charm was just a pretense to hide where he got that knowledge.

In the Justice League episode "Legends", the Justice Guild of America, a team of heroes from a Silver Age Retro Universe, gets notice that the bad guys are planning a crime spree themed for the four classical elements. The Guild members immediately figure out what these refer to, even if they are only tangentially related to the elements themselves: The fire crime is the theft of the famed fire ruby (a gem), the air crime is the theft of an "antique flyer", the water crime is the theft of a new fountain being dedicated by the city's mayor, and the earth crime (this one is a doozy, and the biggest Bat Deduction of all) is the theft of the trophy for the clay court tennis championships. The League is pretty confused by this development, to be fair, which is one part of The Reveal that neither the Guild nor its enemies are real.

Batman Forever: Upon discovering that Edward Nygma was the one sending him creepy riddles anonymously (which to the untrained eye, probably looked stalkerish but harmless), Batman instantly deduced that Nygma had actually killed a co-worker who was thought to have committed suicide. In reality, the four riddles that eventually lead Batman to deduce the Riddler's identity are, on their own, perfectly reasonable: it's the clues hidden in the riddles that defy logic, as it's not readily apparent that they're supposed to be part of a metapuzzle. Each riddle has a number in it: 13, 1, 8, and 5. These correspond to the letters M, A, H, and E. Bruce puts 1 and 8 together, making it MRE. MRE = Mr. E = Mystery. Another word for Mystery is Enigma, leading him to conclude that the Riddler is Mister E. Nygma. At least in the Peter David novelization, Bruce had to spend some time after finding the numbers trying to work out the meaning.

Black Dynamite brilliantly parodies the entire concept here. The logic (if you can call it that) goes like this: They are at a diner that serves waffles that melt in your mouth. M&Ms also melt in your mouth (and not in your hand) and are made by the Mars Candy Company. Mars is the Roman God of War, and his Greek counterpart is Ares. Mars backwards without the S reads "Ram", which is the symbol for Aries. Ares' half-sister is Athena, who is the namesake for Athens, Greece. Zodialogical Astronomy was invented by the Greeks in 785 BC (everyone around the table knows this). 785 is the area code of Topeka Kansas. Which can be shortened to Code Kansas. Code Kansas backwards without the last S gives A Snake Doc. A.k.a. Snake Doctor. Aesculapius is the Greek Demigod of Medicine who believed snakes' tongues had mystical healing power and whose staff surrounded by snakes is the symbol for medicine. Apollo is Aesculapius' father, and a legend involving him and snakes is in both Greek and Roman mythology — Apollo slew the serpent at Delphi. The Serpent was a big ass snake. The South American anaconda is the biggest snake in the world. Anaconda Malt Liquor has the slogan "Anaconda Malt Liquor gives you Wooooooooooo!" "Wooooooooooooo!" sounds like Little Richard. So the motto really is: "Anaconda Malt Liquor gives you Little Richard". Dick is another name for Richard. So the real motto (and the sinister plot) is that Anaconda Malt Liquor gives you a small dick. And their conclusion is immediately proven correct. Hilariously, most of the "deduction" is unnecessary to reach the conclusion, which could have been reached by itself (the shipment containers the crew found all contained Anaconda Malt Liquor).

In Thomas and the Magic Railroad, Alec Baldwin does this by eating vegetables and listing off the random words that pop into his head. *eats a carrot* "Plane... drain... mountain... fountain... That might be something. I think I'll try the celery. Sausage... bicycle... *hic*... Toothpaste... Beach... Beach, that's it!" Could actually be justified here because it's a magical plant from a magical island.

In Evolution, the scientists reason that, since arsenic is poisonous to carbon-based life forms, the nitrogen-based aliens must be poisoned by selenium. How do they reach this deduction? Because arsenic is two spaces up and one space to the right on the periodic table, so this pattern should hold true for nitrogen. They do absolutely zero testing to see if it's true before employing it live. It's also not very sound, since resistance to arsenic poisoning can be built up, and there are other elements that are more poisonous to carbon-based life... like selenium.

The witch/duck scene in Monty Python and the Holy Grail. The "deduction" is: Wood, ducks, and witches all float in water. Wood and witches both burn. So if a woman weighs the same as a duck, then she's made of wood, and therefore a witch.

An aversion occurs in the Batman: Endgame story arc of Batman (2011). Supporting cast member Eric Border is revealed to have been the Joker in disguise the whole time. After he reveals himself Joker explains to Batman the meaning behind the term and is actually pretty annoyed that he didn't catch onto it sooner, despite how horribly obtuse the meaning was.

In the Dark Nights: Metal story arc by Scott Snyder, Superman has a dream where he hears Batman saying "Carpe Diem" as they watched their sons playing the Batman TV Theme, which is related to "C.D.", a code Superman and Batman had for the most dire situations — and he thinks Batman is trying to get Superman to help him. As it turns out, the REAL code is in the song their sons play, which actually goes DC, the reverse of Batman's secret code...a warning not to come. Unfortunately Superman did, allowing the Evil Batmen to use Supes as a living battery.

Joueur du Grenier:
In the test of The Legend of Zelda: Faces of Evil, this is how JdG finds the solution to unlock a door after listening to a really obscure hint in a dialog. He then says that it was a joke: he was stuck there and was forced to read a walkthrough.
The Trope Namer itself is featured in the review of Batman: The Movie, causing a serious breakdown.
Ironically, JdG (or rather, Duck-Man) makes one such deduction himself in the DC Comics games episode. Since the least awful of the games tested by Seb was Aquaman, then Joker-Seb must be hiding... under the sea.

In xkcd:
Beret Guy is a total Cloudcuckoolander in his deductions... but that doesn't mean he's not right. In "Cursed Chair", he's accidentally bought a cursed chair from a mysterious shop, and when he tries to return it, the shop has been boarded up. The other guy remarks that most shops are closed due to the coronavirus. This leads Beret Guy to infer the chair must have caused the pandemic, and he can stop the pandemic if he destroys the chair. He appears to be right. Certainly the floating evil office chair says nothing to deny it.
Further, in "Puzzles", Randall complains about and parodies the prevalence of this in children's adventures:

In The Lost Fleet, Captain Geary reasons why Syndics would delete software from evacuated base and why it looks like things have been broken into using non-standard sized tools is the existence of until now unknown and unsuspected aliens. The people he suggests this to generally state how nuts this sounds, but reluctantly admit they don't have alternate explanations. On the whole, this is a Downplayed example, as even Geary himself thinks it's an insane conclusion. He doesn't start really believing it until he starts finding other oddities that point in the same direction.

Death Note (2017)'s version of L does this a lot because the plot of the movie is so condensed. For example, he concludes that Kira needs a name and a face to kill because he wasn't killed while giving a press conference while he was hiding his face and true name, despite the fact that up until that point Kira hadn't gone after any law enforcement. Based on the evidence he was given, L could have also concluded that Kira only targets criminals, or that Kira wasn't watching the broadcast, or that Kira didn't want to kill L on TV. In the manga and anime, L holds a press conference using a stand-in who was scheduled to be executed anyway. When Kira kills that man but not the real L, L concludes that Kira wants to kill him, but can't due to his name and face being hidden. Since this scene is so compressed in the movie, L's reasoning ceases to make sense.

The Mutants & Masterminds expansion book "Mecha and Manga" introduced the Conspiracy Theorist feat which lets players make Knowledge rolls on completely unrelated (and untrained) knowledge skills after rolling a 20 (or less with further ranks) on their previous skill roll. A series of successive high rolls quickly produces Bat Deductions as your character moves from Knowledge (Technology) to Knowledge (Civics) to Knowledge (Natural Sciences) to note that not only are devices in question mind control devices, but that the particular composition of police officers means the president must be on a secret visit, and that the peculiar white coarse hair caught on the boxes means that there's a diabolical plan by Dr. Silverhair, the transfigured ape turned Nazi, to kidnap the president.

Agent Mulder from The X-Files often solved the case of the week out of the blue, though there were instances of him being wrong in his assumptions or cases where his (or Agent Scully's) logical steps were shown. One of the true non-paranormal detective episodes, "The Amazing Maleeni" about the magician who seems to decapitate himself for real during his act left all the clues in a breadcrumb trail and a sufficiently sharp viewer can deduce the conclusion and unravel the entire mystery just before Mulder gives the solution in the final reveal.

Towards the end of Yakuza 0, both Kiryu and Majima both receive coded messages from the Amon Clan telling them to meet at a specific place. While Kiryu translates the message easily enough, Majima gets the code confused with baseball terminology and instead reads the message as "Just nine pitches. Come to the pitching place. Amore." Despite this mix-up, he reasons that 'pitching place' must mean a 'bullpen' and that 'Amore' is an Italian word and Italian is kinda similar to Spanish before putting 'bullpen' and 'Spanish' together to suss out the correct meeting place, a bullfighting arena, anyway.

In Vampire: The Masquerade there's Dementation, the Malkavian exclusive discipline. The third rank allows one to "Gain insight into the nature of something through seemingly random patterns". This effectively allowed players to jump to horrifically far-fetched conclusions on the basis of very scant evidence. (In-universe, explainable by Malkavians having an unusual and limited kind of Hive Mind possessing all the information to draw these conclusions from either logical deduction or direct precognition... but as every Malkavian is incurably insane — in individual ways — none of that gets through in recognizable form.)

In a season seven episode of Star Trek: Deep Space Nine, Ezri, while trying to solve a murder case, deduces that the killer is a Vulcan who lost all his friends based on the fact that each of the murder victims had pictures of their friends and family laughing in their quarters.

In the same book he also correctly identifies one of the villains because he simply wants to blame someone other than himself for his client's death, and she's handy. He's absolutely astonished to realise, much later, that she is to blame.

Stephen Colbert used this technique to twice pick the Oscar winners. He has a shockingly good success rate.
Colbert parodied himself by using the technique to "pick" the winner of the 2008 Presidential election. He kept using starting points clearly designed to point to John McCain but wound up picking Barack Obama every time. Even when he started on... John McCain. Video
Colbert and others generally use this kind of reasoning in parodies of Glenn Beck's chalkboard illustrations.

Batman:
Justified in Batman (Grant Morrison), where Batman points out that he needs to use half-mad logic and bizarre connective leaps to "match wits" with a rotating group of homicidal, delusional sociopaths, or people will die. Likewise, The Joker himself admits that Batman may have driven him to apophenia, as he has to constantly wonder whether or not the Bat will solve anything he plans, no matter how random everything seems.
During Morrison's Justice League run, Martian Manhunter shapeshifts his brain to make the irrational intuitive regions big and the logical regions small so he can think like the Joker. The chaotic maze he and Superman are trapped in suddenly appears to have a straight path from entry to exit.
An aversion occurs in the Batman: Endgame story arc of Batman (2011). Supporting cast member Eric Border is revealed to have been the Joker in disguise the whole time. After he reveals himself Joker explains to Batman the meaning behind the term and is actually pretty annoyed that he didn't catch onto it sooner, despite how horribly obtuse the meaning was.

In the short story "Who Erased the Eraser?", Batman believes that his former classmate is the Eraser based on Bat Deduction...except that he drives himself into psychological and emotional ruin because he can't make the facts fit his theory. The ending reveals that he was right that his former classmate was planning to become the Eraser, but where things went awry was that his classmate's schemes never actually got off the ground.

L.A. Noire:
Cole deduces that from the corpse of a recently stabbed victim he finds a ticket, therefore the fighter you were looking for is in the theater. Even your Partner lampshades this as ludicrous.
Cole deduces that a car crash victim was raped the day prior to getting involved in the car crash because ripped panties were found in the handbag that was in the car. Although this isn't the most illogical leap in the world to make for a detective, mere minutes later when he's questioning the car's driver, Cole whips the underwear out as proof that the driver is hiding the passenger's rape because the driver didn't mention the fact that the passenger was raped when they were giving a basic description of who she was. To be fair she does make an expression that makes it obvious she's hiding something about the passenger, but it's still an incredibly bizarre leap of logic. And this is made worse by the fact that the game expects the player to be on the same boat as Cole without any prompting whatsoever. Despite the game not even remotely implying it, the player needs to have the theory of rape on hand by the interrogation, and needs to make the incredibly bizarre leap to accuse the driver of lying and then present the underwear to the driver when they describe the passenger without mentioning the fact that she was raped. Due to this, this interrogation question is one of the infuriatingly non-intuitive in the game and trips up close to 100% of all first-time players by official Rockstar Social Club statistics.

In Batman: The Movie, the entire universe runs on Bat-Logic, in the name of fun, though.
For example, at the beginning Batman gets a series of "joking" riddles that vaguely talk about birds and the sea. Batman reasons out that the riddles must be from The Riddler (fair enough), but the joking style is a sign he's working with The Joker (makes some sense). The riddles reference birds and something that "gobbles up" birds, meaning Penguin and Catwoman. Meaning the four of them are working together. And Batman is absolutely right. Even more bizarrely, the riddle that leads to the Penguin and Catwoman deduction is "What weighs six ounces, sits in a tree and is very dangerous?" which Robin deduces is "A sparrow with a machine gun!" This is the right answer.
Two riddles have the answers "egg" and "make applesauce". This means the villains are going to attack the UN. You see, applesauce is a single unified mixture (like the UN), and the egg is a capsule (like the UN).
Then there's the crown jewel of them all...

In Kid Detective, this is seemingly played straight only to be subverted later with more information. One of Abe's first real cases as a child was to find the money stolen from the school fundraiser for animal rescue. He figures it must be the local rulebreaker who had once been bitten by a dog, they find the cashbox in his desk the next day and he held this victory as a badge of honor. He wasn't the real thief, as Abe was informed years later as an adult. The whole scenario was staged by the antagonist as a test of Abe's abilities and see how his mind worked, implying that they framed the other kid because Abe came to that conclusion. This was a prelude to a kidnapping of a classmate and doing so with confidence that Abe wouldn't find the right culprit.

Death Note:
Near does this, especially in the anime, which compressed a 5 volume arc into 11 episodes. The manga explains his deductions a lot better — with huge walls of text.
In early episodes of the anime, L does a bit of this but it drops off as enough clues are established for the audience to follow what's happening. The bilinear narration between Light and L only makes it all the more obvious.
The light novel takes it Up to Eleven. Every murder scene involves a few absurdly complicated "clues," such as "Quarter Queen" was a child, which means her initials should be in lower case, and since she was positioned upside-down, you're supposed to flip them, therefore qq makes BB. Yeah. Half-justified by the fact that L knows that the killer is B, and Rue Ryuzaki IS the killer and is manipulating Naomi Misora into "solving" clues that he laid out, which are in fact all irrelevant, except to set up the final contest between her (and L by extension) and B. But as a meta example, that you were supposed to deduce that the guy who looks and acts very much like L was, in fact, B, who planned on killing himself, was rather out of left field.

In Red vs. Blue: Revelation, Sarge uses this from a radio conversation with Simmons to figure out that Wash and the Meta have taken Simmons and Doc hostage, and killed Donut and Lopez. The sequence starts out with Simmons leaving several good clues and Sarge being surprisingly clever with genuine deductive reasoning, but quickly devolves into this trope, as Grif looks on bemusedly. By the time we get to see Simmons again, it's not even clear whether he was leaving clues or, as he suggests, he couldn't say anything with Wash and the Meta listening and Sarge simply put it all together through his own insane brand of logic.

Naturally, episodes of Batman: The Animated Series involving the Riddler had this sometimes:
"What is Reality?" begins with three computers crashing around Gotham, displaying only a riddle on screen: "Where does a 500-pound gorilla sleep?"note Anywhere it wants to. "What's worse than a millipede with flat feet?"note A giraffe with a sore throat. "How do you fit 5 elephants into a compact car?"note Two in the front, two in the back, and one in the trunk. Train of logic: the Riddler doesn't usually use such commonly known riddles meaning the answers to the riddles are a red herring. The riddles themselves all contain numbers: 500, 1000, 5. Convert to roman numerals and get D,M,V... the Department of Motor Vehicles!!!
After escaping a trap from Riddler, the latter calls Batman on a payphone and says "Ask me no questions and I'll tell you no tales. It all makes sense when you add it up." followed by a handful of coins falling in the change tray:
The silliest thing about this? Batman was going to go back there eventually anyway.
Finally, at the end of the episode, Riddler casually remarks "If the planet were equitable, I'd still have my old job" right before his virtual reality program crashes trapping him inside. Batman immediately deduces that to be a clue to his hideout: "If the WORLD'S FAIR, I'd still have my EX-POSITION". Robin is not amused.

Parodied (like everything else) in the Angie Tribeca episode "Ferret Royale" — detective Geils goes from "apple" to "orchard" to "farm" to "granny smith" to "Grandma" to "nursing home" to "soft food" to "applesauce"... and then back to apples, starting the loop over again and repeating it two or three more times.

This is a key feature of Case Closed, owing to difficulty translating. In the original Japanese version, an unfortunately large number of clues rely on Japanese puns and cultural references that can't really be translated, so non-Japanese readers/viewers can't fit the clues together. Though the case involving Kan'o (spelt using the characters 'ka' + 'n' + 'o') referring to the person Kano (spelt using the characters 'ka' + 'no') was easier to solve for Western audiences.
In addition, the author likes using Gratuitous English using wordplay to assign significance to English words. Thanks to the author's limited grasp of the language, these often take the form of bat deductions, such as the word SIS being code for the CIA. It has something to do with sisters and systems.

In Archie Comics "Archie at Riverdale High" #33, in the story "The Outsider", a new student named Buck Bailey is repeatedly pulling nasty practical jokes on the other students, including some kids twice his size. Archie wants to help Buck (before the other kids retaliate en masse) and realizes that no one went out of their way to welcome Buck as a new student. He summarily concludes that Buck was only pulling practical jokes to get attention, and turns out to be correct, leading Archie to give Buck a more acceptable way to be popular.

Inverted in Touch Detective 3. Inspector Daria and Mackenize are stumped as to why someone has been going around stealing nothing but bananas. Daria "reasons" that the only kind of person who would steal people's bananas is someone who doesn't respect banana lovers, and as a sentient being made out of bananas would, by definition, be a banana lover, the thief's objective is absolutely NOT to make a sentient Banana-Man out of their stolen bananas. This is absolutely the thief's objective.

Heavy Rain: While Norman is playing a video of a fight between himself and the Origami Killer from earlier in the game he notices that the killer has a golden watch, therefore he is or was a cop because the station always gives that model for promotions. In fairness, he's desperate, grasping at straws, and it's still not enough information to find the real killer. In fact, if you think that's the final clue, then you'll accuse the wrong person (the local Rabid Cop). You have to cross-reference that with all the other clues you've gained to narrow things down to one person.

At the beginning of Journey 2 The Mysterious Island, Hank and Sean deduce the location of the eponymous island from a coded message sent by Sean's grandfather Alexander. The phrase "Son of Steve, born in 1883" leads them to Robert Louis Stevenson's Treasure Island, written in 1883, and the phrase "his last name is going fast" and the mention of the name "Lemuel" lead them to Gulliver's Travels, written by Jonathan Swift. They then piece the maps and coordinates in the three books together to form a map of the island.

In Superman: The Movie, Lex Luthor somehow reasons that kryptonite is lethal to Superman just because he is from Krypton and that pieces of Krypton must have fallen to Earth just because of the location and time of Krypton's explosion in 1948 (which he knows from reading details in Superman's interview with Lois Lane, which Superman never actually provides in the interview scene — and according to the disembodied voice of Marlon Brando by the time the rocket ship carrying Superman reached Earth, thousands of Earth years passed). In addition, he somehow knows that Kryptonite strips Superman's power while slowly killing him (thereby preventing Supes from flinging it away while still under its effects). Luthor somehow knows from all this what kind of crystal to look up in his library, too. "Deductive reasoning, that's the name of the game," he says. He gets one pass in the director's cut, however. He tried EVERYTHING ELSE first, with fire, ice, lightning, etc.

In The Secrets of Isis, Andrea (Isis's alter ego) has her car stolen when she visits the library. In the spot where her car was parked, she finds a rag, which she takes back to her lab to have it analyzed and decides it has enamel laquer on it, which means that her car isn't being shipped out of the state to be sold, rather it's being kept in California to be repainted. Next, she says all the car thieves in a car ring had been busted except for one guy who got away, so it must be him, then determines her car must be at this person's salvage yard. When she gets there, there's a sign on the door that says it's out of business, but there's an old chain on the gate with a new lock, which could only mean one thing: the car thieves are operating out of this salvage yard!

On the Black Dynamite animated series, in a Call-Back to the movie, the characters use the following chain of logic to figure out the episode's real plot: there's Jello and grits on Black Dynamite's plate. Jello is jiggly. It's jiggly because it contains collagen. Collagen is also found in marshmallows. Marshmallows are used to make s'mores. The only thing blacker than a s'more is a black panther. The other kind of panther is The Pink Panther. The Pink Panther theme goes "da-dant, da-dant, da-dant," which sounds like "dead ant." Ants live in colonies. Another word for a colony is a clan. "Clan" is a common term for the Ku Klux Klan. So the murders are being committed by an alliance between the Black Panthers and the Ku Klux Klan. They only get one fact wrong; it was a splinter group called the Black Pumas (they couldn't get the trademark) instead.

Subverted in The Princess Bride: Vezzini uses this to "deduce" which glass contains poison ("Iocane comes from Australia, as everyone knows, and Australia is entirely peopled with criminals, and criminals are used to having people not trust them...") Arguably, he isn't actually trying to Bat-Deduce the location of the poison — he's just trying to get a revealing reaction out of the man in black (which the man calls him on). Either that, or he's just too caught up in his own cleverness to realize that he's thinking in circles. The real irony is that all of his Bat Deductions lead to the right answer, even though he doesn't realize it: He successfully proves that he shouldn't drink from either glass.

In Without a Clue, lampshaded. A mysterious number is given, and Sherlock Holmes uses a few long and complicated leaps of logic to deduce that it means a specific theater. Specifically, the number, when taken as a chapter/verse pairing in the Book of Psalms (the kidnap victim's favorite book of the Bible), it references the name of a play that was last performed at that theater. At the end, Holmes and Watson explain to the person who left the clue how they figured it out — the victim reveals that the number was simply the address of the theater he was being held at.

In Disco Elysium, the Inland Empire skill (the Shout-Out to the David Lynch film of the same name is very deliberate) essentially allows the Player Character do to this. Well, sometimes. Quite a few times it just makes him see supernatural events, vast conspiracies, and vast conspiracies involving supernatural events where there are none, but there are also many times where the far-out deductions that the skill allows the player to make is actually on the money. For instance, you can tie one character correctly to a piece of evidence because it contains racism, they made a bigoted remark, and "that's not something a good person would say". They confess immediately.

In The Mask Lt. Calloway zeroes in on Stanley as the prime suspect for a bank robbery because he recognized a torn strip of fabric as part of Stanley's pajamas and reasoned that nobody else would have that bad a fashion sense. Why he reasoned that Stanley would be wearing his pajamas in a fairly popular and exclusive nightclub is anyone's guess, as is how he connected Stanley's presence at the Nightclub to a bank robbery and shootout across town.

In one episode of Criminal Minds Reid correctly figures out who the murderer is by hypothesizing the murderer had multiple personality disorder, based on a single anomaly in a polygraph test because the suspect got a control question wrong. Instead of concluding the subject failed math, he went through the conclusion that on that one question a second personality took over (a phenomenon they had no evidence for) knew the answer to the question, lied about it (even though it had no incentive to do so on the first question), and that lying on the test meant that the suspect was indeed the murderer. To be fair, Reid had already clued in that something was wrong: his first hint was the uncharacteristic behavior the suspect had after the test.

The Batman (2022): Mostly averted here, to show how this Batman is still a little rough around the edges. True to his usual form, the Riddler leaves behind numerous clues with his crimes, but Batman needs a lot of help to figure out what many of them mean. For example, the Riddler is very disappointed that Batman didn't manage to discover the masterstroke of his grand plan despite having left the clue to find it in his very first murder (the clue was that the murder weapon he used was a carpet-removing tool, indicating that he had hidden the plans for his masterstroke under the carpet in his apartment). Batman isn't able to figure it out until a police officer points it out to him, and by that point, it's too late.

A Running Gag in the episode "Cancelled", a parody of Independence Day, the scientist (Jeff, for Jeff Goldblum) would fixate on a random element that has nothing to do with the problem whatsoever and follow a completely nonsensical chain of reasoning, eventually arriving at the correct solution. For example:
Also parodied in the episode "Mystery of the Urinal Deuce", where Cartman claims to deduce that Kyle caused 9/11:

In Book Girl and the Famished Spirit, the Literature Club receives a mysterious letter written in a number code; Tohko immediately and incorrectly deduces the meaning based on what seems to be free-association.

Parodied in JoJo's Bizarre Adventure Abridged, where Joseph, through an insane series of jumps ends up with a false deduction. Fortunately, Dio doesn't know he's barking up the wrong tree and ends up spilling the beans before Joseph can lay his bizarre theory on him. The leap he makes from there makes no sense either: He deduces that Dio's Stand has the power to breathe fire.

Parodied, and ultimately subverted, in Amphibia. Anne and Marcy are sent a puzzle-gram by King Andrias, and Marcy solves the first two clues all by herself, making Anne feel inadequate by comparison. Her attempt to "fake it 'til you make it" and solve the third and final clue (which has Marcy stumped) consists of a baffling chain of logic that leads her to deduce that the final part of the message is in the sewers. Not only is Anne completely wrong, but she almost gets the entire party eaten by a giant Sewer Gator in the process.

Joyfully subverted in Sherlock Holmes' The Adventure of the Yellow Face. The titular detective extrapolates a complex theory involving murder and foul play to explain the case to Watson without having so much as set foot in Norbury. And then, rather than every leap of logic/intuition being correct — he turns out to be ENTIRELY wrong in all his deductions — the reason the client's wife needed money and was going away at random times was that she was trying to secretly raise her child from a previous marriage.

Vesta Gul, the narrator of Death in Her Hands, takes this method to an extreme. Finding a note that reads, "Her name was Magda. Nobody will ever know who killed her. It wasn’t me. Here is her dead body," she responds by making up names and characteristics of people involved, before she talks to anyone. Something of a Deconstructed Trope in that she doesn't solve anything this way.

Justified in Batman (Grant Morrison), where Batman points out that he needs to use half-mad logic and bizarre connective leaps to "match wits" with a rotating group of homicidal, delusional sociopaths, or people will die. Likewise, The Joker himself admits that Batman may have driven him to apophenia, as he has to constantly wonder whether or not the Bat will solve anything he plans, no matter how random everything seems.

An episode from the last season of Charmed opened with Billie deducting that, to search for her sister who was abducted by demons, she needed to find a powerful bloc that demons would work with. Simple — corporate America. And since she's read this story about a guy who was kidnapped as a child and now works with "corporate America," she's going to try a magic spell to see if he has anything to do with demons. And this works.
