Basic Trope: An argument with bizarre and nonsensical reasoning.
- Straight: Alice, who may be Literal-Minded, thinks that purple and blue are the same color, so she "proves" it by reading Roses Are Red, Violets Are Blue....Alice: If violets are blue, then purple and blue must be the exact same color.
- Exaggerated:
- Alice thinks that purple and blue are the same color so she "proves" it by reading Roses Are Red, Violets Are Blue... and takes it up to eleven.
- Word Salad Philosophy.
- The villain kills an entire town worth of people because according to him, "if everyone is dead, no one will be."
- Alice's logic is not only nonsensical but complete self-inconsistent, like basing some of her arguments on the idea that owls are slimy sea-dwellers, and the rest on the idea that owls are fire-breathing serpents, and then somehow using both trains of thought in tandem without ever once caring for the fact that they are completely irreconcilable.
- Downplayed:
- Alice is probably just Comically Missing the Point of Roses Are Red, Violets Are Blue.... She thinks that "violets are blue" is a factnote instead of a metaphor.
- Fridge Logic for minor things.
- Logical Fallacies when not crazy enough for this trope.
- While Alice's reasoning is not applicable to reality, it is consistent unto itself and can form a coherent logical structure for a hypothetical Cloud Cuckooland, if such a place exists.
- Alice's reasoning isn't EXACTLY unreasonable, but it's far from the first thing somebody sane would think in that situation.
- Alice has an unhealthy and quixotic view of the world (i.e Black-and-White Insanity), but despite these intellectual failings any associated logical breakdowns rarely encroach upon her regular functioning.
- Justified:
- Alice is a ditz or a Cloudcuckoolander which is why she comes up with the idea that purple is the same color as blue.
- Alice is normally a sensible person but she's currently in an extremely stressful and/or emotionally intense situation and isn't thinking clearly at the moment. Later on she acknowledges this, and no one thinks less of her for the temporary lapse in judgement.
- Alice is completely colorblind making her incorrect inferences more reasonable. They really do look to be the same color to her.
- Alice has an incredibly warped sense of morality that would be commonly associated with aliens.
- Alice is setting up a(n attempted) legal fiction.
- Inverted:
- Alice reads Roses Are Red, Violets Are Blue.... She finds the poem ludicrous because she knows that most violets are purple. And that purple and blue are not the same color.
- Despite Alice's logical reasoning of how violets are not blue, everyone still denies Alice's claim.
- Fridge Brilliance.
- Subverted:
- Her Insane Troll Logic ends up being true after all.
- Bat Deduction.
- Right for the Wrong Reasons.
- Alice was joking.
- Alice is deliberately screwing with us.
- Alice is being sarcastic.
- Double Subverted: Alice is proven right, only for the scientist who proved it right turned out to have used the same logic as she did.
- Parodied:
- Alice uses this as an argument for/against creationism.
- Alice figures that, since a watched pot never boils, then a watched pot of water is the perfect heat sink for her gaming setup.
- Zig-Zagged: The laws of the universe are changing, and as a part of this, various colors keep becoming other colors. Alice is repeatedly proven right and wrong, and near the end of the story, right and wrong become the same thing anyway.
- Averted: Alice doesn't even bother proving that blue and purple are the same color.
- Lampshaded: "What the FUCK are you talking about?!"
- Invoked: Chewbacca Defense.
- Exploited: Bob makes Alice use this argument to win a bet.
- Defied: Alice studies debate so she can make rational, logical arguments.
- Discussed: "Alice tried to prove that violet and blue are the same with some insane mumbo-jumbo."
- Conversed: "You know, there was this show where this girl tried to argue that blue is purple. She was crazy."
- Deconstructed:
- Alice's attempts to prove that violet and blue are the same color make her look ridiculous and she ends up becoming a laughing stock.
- When Alice finishes explaining why violets and blue are the same color, everyone is quiet for a moment before someone shouts "THAT DOESN'T MAKE ANY SENSE!"
- The explanation might not make sense to other people because Alice is from another country, enforcing Values Dissonance because there isn't anyone who understands her different mindset and standards.
- Alice is a Humanoid Alien with different eyesight to ours, and a different system of logic. Therefore, she sees purple and blue as literally the same color, and assumes that the poem means humans see the same way.
- Reconstructed:
- Alice is happy, because being a laughingstock means that people are listening to her.
- Alice explains her answer with more Insane Troll Logic.
- Another person from Alice's home country/planet, moves in.
- Alice moves back to her home country/planet.
- Played for Laughs: Alice makes a statement so ridiculous that not even she believes it, but isn't bothered by it either.
- Played for Drama: Alice is The Alleged Expert whose expertise is needed in a situation that threatens one or more people's lives. She uses this as the basis for her rationale, however, and she's discredited.
- Played For Horror: Alice's reasons why she needs to kill some people to save many more are... unusual, to say the least.
- Implied: Alice is leaving a debate stage with her opponent, Bob, and his supporters laughing at her.
Back to Insane Troll Logic which isn't insane because the trope itself would have to be in an insane asylum to be insane. Because this trope is in the internet, there is no way it can physically be in an insane asylum. It would also have to have eaten at least six pounds of beef and ice cream per day to qualify for insanity legally. In conclusion, the trope is not insane. HAHAHAHAHAHAHA...
