Logical Fallacies
aka: You Fail Logic Forever
Including that one.

*Producers notice a fairly small sign blending in, reading "Flim Springfield"*
"This place must be hot. They don't need a big ad, or even correct spelling."
"Can't argue with that logic."
Radioactive Man Producers, on the topic of Springfield as a movie location, The Simpsons

Logic. Every story needs some of it, unless you just want a series of unconnected images and no plot to speak of.

The problem is logic requires writers to think pretty hard about what they write, and not all writers have time or inclination to do so. So they take shortcuts, creating fallacies which at best can lead to plot holes, and at worst undermine the entire story.

Fallacies are common errors in logic. By strict standards, fallacies don't address the truth of the premises or syllogism; they only address the validity of the logic, and as this page demonstrates, "truth" and "validity" are not the same thing when speaking of formal logic. There is a reason there are Critical Thinking classes.

Logical fallacies are faulty reasoning. This doesn't mean that they aren't effective at persuading. Many of them are extremely effective tools of persuasion. The key is that there are two primary routes of persuasion - the central (logical) route and the peripheral (emotional) route. To persuade someone using the central route, you need logic; a logical fallacy will make your argument fall flat on its face. To persuade someone using the peripheral route, you don't need logic; you simply need to play upon emotions. Some people are impassive to emotional appeals, and so you must use logic to persuade them; others are confused by logic, and so must be persuaded through emotion.

For examples of writers intentionally failing logic forever, see Insane Troll Logic and Chewbacca Defense. Not to be confused with Logic Bomb.
