ABSTRACT
There are two views of scientific thinking attributed to Karl Popper. The more popular among economic methodologists is not very challenging and to be useful requires only a minor adjustment to commonly held views. The less well known view considers Popper's theory of science to be revolutionary and extremely challenging and requiring a major change in attitude towards science and scientific thinking. In this paper I will explain the nature of these two views and their implications for the study of economic methodology. Also I will examine why there are two different views and why one is more popular than the other. Above all, I will try to explain why I think the less popular is the more important.
