The term non sequitur refers to a conclusion that isn't aligned with previous statements or evidence. In Latin, non sequitur literally means "it does not follow."
A statement that is labeled a non sequitur is one that is illogical. For example, if someone asks what it's like outside and you reply, "It's 2:00," you've just used a non-sequitur, or made a statement that does not follow what was being discussed.
There are two main kinds of non sequiturs: logical non sequiturs and literary non sequiturs. Let's take a look at each type of statement(s) that "does not follow".
Logical non sequiturs are akin to fallacies. They both defy the basic rules of reason and are usually based upon unsound arguments.
Not only do non sequiturs fail to follow logic, they're usually untrue, having jumped to unfounded conclusions.
In the logical non sequiturs below you'll see they either don't follow a line of logic or are potentially fallacious in their nature.
Literary non sequiturs are often used for comedic purposes. In these instances, something is stated that bares no relevance to what was being discussed.
These non sequiturs are so far-fetched, they serve as a literary technique for some added texture and comedy. Often, they catch people off guard, surprising a laugh out of them.
It was a spring day, the sort that gives people hope: all soft winds and delicate smells of warm earth. Suicide weather.

"I love you," she said. She nestled closer, her hand moving up the back of his neck. The wind lifted. "Don't kill me," he said. "I'm not going to," she said.

"You should learn not to make personal remarks," Alice said with some severity. "It's very rude." The Hatter opened his eyes very wide on hearing this; but all he said was, "Why is a raven like a writing-desk?"

POLONIUS: If you call me Jephthah, my lord, I have a daughter that I love passing well.
HAMLET: Nay, that follows not.

ESTRAGON: What did we do yesterday?
VLADIMIR: What did we do yesterday?
VLADIMIR: Why . . . (Angrily.) Nothing is certain when you’re about.
ESTRAGON: In my opinion we were here.
VLADIMIR: (looking round) You recognize the place?
ESTRAGON: I didn’t say that.
ESTRAGON: That makes no difference.

“What are you doing?” Yossarian asked guardedly when he entered the tent, although he saw at once.“There’s a leak in here,” Orr said. “I’m trying to fix it.”“Please stop it,” said Yossarian. “You’re making me nervous.”“When I was a kid,” Orr replied, “I used to walk around all day with crab apples in my cheeks. One in each cheek.”
- Catch-22, Joseph Heller
GUILDENSTERN: The scientific approach to the examination of phenomena is a defense against the pure emotion of fear. Keep tight hold and continue while there’s time… The sun came up about as often as it went down, in the long run, and a coin showed heads about as often as it showed tails. Then a messenger arrived. We had been sent for. Nothing else happened. Ninety-two coins spun consecutively have come down heads ninety-two consecutive times — and for the last three minutes on the wind of a windless day I have heard the sound of drums and flute.
ROSENCRANTZ (cutting his fingernails): Another curious scientific phenomenon is the fact that the fingernails grow after death, as does the beard.

There's a bit of a dual purpose behind non sequiturs. On one hand, they're fallacious in nature, often causing people to spread inaccurate information.
On the other hand, non-sequiturs are so wrong, they're comedic. Watching someone make a giant leap from one thought to another can be unexpected or absurd enough to surprise a laugh out of the audience.
If you're writing something entirely research and fact-based, be sure to avoid these statements. That's a sure-fire way for someone to flag your writing. If, however, you're looking to have some fun and throw a curveball into the crowd, see if you can come up with a laughable non sequitur to make readers stop and think, "Wait a minute…"
