This is how analogy works: if two things, A and B, are similar in some aspects, then it is possible or even likely that they are similar in other aspects; and our familiarity with A will make the inferred similarities between A and B more acceptable to us. An argument that us a well-known similarity between two things as the basis for a clusion about a relatively unknown characteristic of one of tho things is an argument by analogy （Bro; Keeley, 2007: 129）. For instance, during the 2004 presidential ele in the Uates, oppos of the war in Iraq pared it to the Vietnam War, becau this analogy induces Ameri people to traheir ive feelings about the Vietnam War into their ception of the war in Iraq; furthermore, it makes people eain the possibility that this war, like the Vietnam War, will end in fiasco eventually. Analogies of this kind often appeal to relatively stroions, a appealing to emotion will risk jeopardizing the rationality or impartiality of a stific study, therefore in academic writing, argument by analogy should be treated with extreme caution. The following is a list of questions, adapted from Hart （2006: 117）, which might help to asss the validity or appropriateness of an analogy in your study:
