Social scientists interpret reality by reference to analytical and theoretical constructions. We do not see how the world changes, how resources shift between countries, regions or participants in the productive process, or even how institutions adjust. However, we have to try and understand what is happening around us, to analyse it and to interpret it. During times of relative stability our ingenuity is not greatly taxed and we get by using established routines to help our interpretation. But when change accelerates, new approaches are required. New research then needs to answer new sets of questions.
