Internal conflicts have a personal nature. By comparing personal internal conflicts to Aristotle's structure for dramas, these conflicts can often be recognized. Aristotle's drama structure divided the play into five acts with a hero, a villain, an external conflict and climax, and an emotional cleansing involving an internal conflict. Real life internal conflicts often involve character traits and values that are easily identified by this method.[5] (Character traits and values are discussed in the section on interpersonal relationships.) * * * * * _Fact Gathering_ in Problem Solving. The preferred order for gather facts is based on the order of reliability: library research, asking someone knowledgeable, and brainstorming. Facts should be tested for logic, emotional fallacies, and the credibility of "expert" witnesses. Facts gained from research in a library are easiest to verify, and other methods of gathering facts must often be re-verified through library research. Logical and emotional weaknesses of arguments can often be recognized by the use of certain fallacy recognition checklists.[6] The most widely used of the fallacies is the over or under generalization: everyone (all, without exception, none, never, no one) rode a bicycle when only two years old.[7] * * * * * The more common persuasive fallacies are: Logic Fallacies. 1. Generalization -- It is raining everywhere. It has not rained anywhere. (The exception is discounted.) 2. Circular argument -- That team is the best because it is the greatest. (Similar adjectives describing each other.) 3. Either or fallacy -- Either the city will drill more wells or it will run out of water. (This ignores the possibility of water pipelines, river dams, desalinization, etc.) 4. Cause and effect fallacies -- two kinds: A. Single cause fallacy -- The streets are wet, therefore it has been snowing. (This discounts other causes like rain.) B. Guilt by association -- He has a friend that is a Japanese, therefore he must be Japanese in his soul. * * * * * Emotional Fallacies. (These are intended make a person fear loss of friendship.)[8] 1. Generalization-Everyone is doing it. 2. Snob Appeal -- A special thing for a special group: Heroes wear only Hot Stuff clothes. 3. Loaded Language -- Emotionally connotative terms of derision: He is a "Mutt." (Not only a dog but also a worthless cur.) 4. Name Calling -- This is often used to discredit someone. It is also often a problem evasion rather than a problem solving strategy that uses: i. Sarcasm. ii. Cynicism. * * * * * Credibility Fallacies. Credibility fallacies are those in which uncertified people present themselves as experts: the famous actor dressed as a doctor recommending a certain medicine. The actor is not a trained professional and has no professional credibility. Fact And Opinion.
