2.3 Writer's Workshop: Persuasive Argument
You should also revise your work to eliminate any errors in logic. A logical argument has to be reasonable and make sense. If yours isn’t, then it won’t be very persuasive.
Some common errors in logic include:
1. Hasty Generalization – This type of argument reaches a conclusion based on too little evidence or too few examples. For example, we might see one event and conclude that all similar events will have the same outcome. This isn’t necessarily true. For example, a snowboarder might make a jump without falling, so we might conclude that the jump is safe for all snowboarders. The fact that the first snowboarder was an expert and had done the jump many times may not have been considered.
2. Begging the Question – This can happen when we insist that something is true but don't have proof. For example we might say, "Anyone can see that our basketball coach is incompetent, he should be fired immediately." This statement has no supporting evidence and the argument expects readers to start from the same point of view.
3. Faulty Cause and Effect – A common problem can come from thinking that one event causes another without enough evidence. Superstitions often come from this type of thinking. For example, a baseball player may always tweak his helmet or hit the plate a certain way before swinging at the ball, believing that if he doesn't do this, he will miss. Similarly, a writer might conclude that one event causes another without enough evidence.
4. False Premise – This error happens when an argument starts with a wrong assumption. For example, you might say, "A mother bear will not attack to protect her cubs." If you move on from there in real life, you would likely discover that this premise is false.
5. False Conclusion – You might reach a conclusion in a persuasive argument that doesn't follow from the facts or examples. For example, you might conclude from watching a number of TV shows that all TV shows are boring, but you may be watching a channel with nothing of interest to you.
6. False Analogy – Someone who tries to argue that if things are similar in some ways, then they are similar in other ways makes this error. For example, a writer might argue that because dogs and cats are both house pets and since dogs will fetch sticks, cats will fetch sticks too.
7. Ignoring the Issue – This error happens when you argue things that are irrelevant. For example, you begin by discussing whether or not a movie is worth seeing, then say the theater is beautiful or the popcorn is lousy. Those things have nothing to do with the movie's quality.
