This paper argues that statistical inference of social data (e.g., stock market, human/organizational behavior, etc.) cannot be analyzed with the same statistical tools used in natural sciences. In traditional statistical inference, when one examines the probability of events, the uncertainty lies in unknown outcomes.  In social-science settings, however, in addition to outcome uncertainty, one often does not know the underlying distribution of events. So, on top of outcome uncertainty, we have to deal with distribution uncertainty (also called ambiguity in the economics literature).  We discuss how inference should be done when there is ambiguity in social data.
