Assumptions and Fallacies
Write a 150- to 200-word response to each of the following questions:

Your mind takes for granted that your assumption is true Your beliefs (assumptions) cause you to come to conclusions (inferences). Your inferences then cause you to act accordingly. Ex. If I walk toward you with my hand out and smiling, you'll probably infer that I intend to shake your hand. Your assumption of my intent is based on similar experiences from your past. Those past events formed your belief about such situations.
What are fallacies? How are fallacies used in written, oral, and visual arguments? What might you do to avoid fallacies in your thinking?
Fallacies are defined as a mistaken belief and based on an illogical argument. A fallacy is simply a flaw in logic, where the argument (or answer or result) given does not match the evidence as set out. In logic and rhetoric, a fallacy is
