The Journal of Economic Methodology, the leading peer-reviewed journal on the philosophical foundations and methodological practice of economics, has published a special issue devoted to George Soros’s theory of reflexivity. The issue contains a new article by Mr. Soros articulating his most recent thinking on reflexivity and fallibility, the role of those concepts in social science, and their contribution to events such as the 2008 financial crisis and euro crisis. The issue also contains contributions, responses and critiques from 18 leading scholars in economics and the history and philosophy of science.
