Criticism of other's writings

I have noticed in many arguments and essay papers out there, there are many common fallacies in the arguments and claims people use. This tends to occur when there is no vast clear evidence to support their claims and they use fallacies because they sound convincing and true, when really they aren't. The logic isn't there in the writing, and often times makes the paper weaker in the end. I feel that many people suffer from this same tendency. We learn in English classes to be persuasive and use convincing language, but little stress is placed on the actual argument. So we train ourselves to argue in circles and reiterate a point in numerous different ways. I feel that with more emphasis on logic and reason we can learn to avoid fallacies in our arguments.
