The STS cross-chapter group meets in Hannover, on Jan. 13-15, 2016, to brainstorm about the role STS can play in Rethinking Society, and the notion of Social Progress. The participants of the workshop are authors spread over all the chapters of the IPSP report to bring the perspective of STS scholarship into the report. The workshop is co-organized by Helga Nowotny and Johan Schot. For information, contact Johan and follow @Johan_Schot.
