When there is innovation, people tend to use the success into other fields as analogy. For example, The relationship of Information Theory and Statistical dynamics is analogy. And I have found the analogy of Chaos theory in various fields.
Analogy motivates scientific innovation. It is the fact. But especially for social science, it is difficult to confirm the analogy is right or not for each case.
If analogy is failed, it is fantasy. I have read many books to make this site. Sometimes I am confused about "Is this theory whether analogy or fantasy ?"
Analogy is useful and interesting. But we need attention when we use it.
