The concepts that I believe that needs more explanation are fallacies. Most people do not realize that there are so many different types of fallacies. One type of fallacy that I feel is used by a lot of different people every day is the ad hominem fallacy or as it is also known as the personal attack fallacy. As you can guess from the second way of saying it is a fallacy that occurs when there is a disagreement and instead of refuting the argument the person personally attacks the other in order to make the argument seem invalid.
One other type of fallacy that really seems very commonly used in everyday life is the appeal to pity. When you use this you are trying to evoke emotions in order to initiate the proper response. You see this type of fallacy mostly when different types of organizations are advertizing something. For example, when you see the commercials on television about sponsoring a child in another country, the commercials show sad little children in black and white. This evokes emotions of many people which makes them sad for the children and makes them do what the commercial says, sponsor a child.
