This report argues that there exists a pervasive tendency for analogies to contribute to the development of entrenched misconceptions in the form of reducing complex new knowledge to the core of a source analogy. The report presents a taxonomy of ways that simple analogy induces conceptual error and an alternative approach involving integrated sets of multiple analogies. The use of multiple analogies is illustrated in the report by the example of force production by muscle fibers. The report concludes with the argument that the situation of analogy is one instance of a more general pattern of misconception attributable to the use of single knowledge sources when compilation of multiple sources would be more appropriate. (Eight figures illustrating multiple analogies are included, and 21 references are attached.) (RS)
