His focus of interest is the argumentations and rethorics used, for which he created a classification and uses a matrix to analyse how they operate. As an illustration, Héran takes the issue of religious slaughter to outline differences in debates between France and in the Netherlands.
François Héran, a philosopher by training, first carried out research in rural France, southern Spain and Bolivia as a sociologist and ethnologist. Currently director of research at the National Institute for Demographic Studies (INED), he studies the public and political debate on immigration in France and the Netherlands in 2011 and 2012.
He is particularly interested in the arguments and rhetoric used, and has established a classification and an analytical grid to understand how they work. To illustrate his point, François Héran takes the subject of ritual slaughter and observes the difference in treatment of the debate in France and the Netherlands.
