In early May Rainer Hegselmann (MODUS, University of Bayreuth & Frankfurt School of Finance & Management, Germany) visited our Department. Rainer is the founder of a highly popular major at the University of Bayreuth combining philosophy and economics, and co-author of the opinion dynamics model known as the Hegselmann-Krause model (JASSS 5(3), art. 2). At the KZSiRO Seminar he told the story behind the Philosophy & Economics major and a day later at the S3 Seminar gave an inspiring talk entitled Computational social epistemology: A case study on two-armed bandits versus inductive truth seekers and epistemic free riders with bounded confidence.
