introduction: reassessing the methodology of process tracing

Although having been practised in the Social Sciences for decades, it was only in recent years that process tracing has gained prominence in methodological debates in political science. In spite of its popularity, however, there has been little success in formalising its methodology, defining its standards, and identifying its range of applicability. This symposium aims at furthering our understanding of the methodology by discussing four essential aspects: the underlying notion of causality, the role of theory, the problem of measurement in qualitative research, and the methodology's relationship with other forms of qualitative inquiry. It brings together methodological and substantive articles by young European scholars and summarises a round-table discussion with Peter A. Hall held at a workshop at the University of Oldenburg, Germany, in November 2010.
