See Keith J. Holyoak and Paul Thagard, Mental Leaps; Analogy in Creative Thought 137 (1995)("Analogy is not a surefire shortcut to expertise, far less a substitute for careful thinking and detailed study of a new domain. But when it is used carefully -- when a plausible analog is selected and ampped, when incferences are critically evaluated and adpted as needed, and when the deep structure of the analogy is extracted to form a schema--analogy can be a powerful mental tool. At its best, analogy can jump-start creative thinking in a new domain and through successive refinements move the novice along the path to expertise."); Douglas Hofstadter, Fluid Concepts and Creative Analogies: Computer Models of The Fundamental Mechanisms of Thought 86 (Basic Books: NY 1995)("It is my belief that pattern perception, extrapolation, and generalization are the true crux of creativity").
