This year’s medal is awarded to Bjoern Ross, Laura Pilz, Benjamin Cabrera, Florian Brachten, German Neubaum, and Stefan Stieglitz, all of whom were based in Germany when the paper was submitted (Bjoern Ross has since moved to the University of Edinburgh). 

There are growing worries that malicious actors might spread misinformation online to manipulate the public by using automated bots. Research has already found evidence of social bots being used in regard to voting for the US presidential election and the outcome of the “Brexit” referendum in 2016 on membership of the United Kingdom in the European Union. This study considers the role of social bots in influencing public opinion expressed on social media and thereby addresses a highly significant and important issue for global society. The paper has theoretical novelty by introducing the spiral of silence theory to the information systems domain. The paper uses agent-based modelling to investigate the possible influence of social bots on public opinion. The study reveals that it only takes 2–4% of human-like social bots to sway the opinion climate in two out of three cases. The judges particularly liked the contemporary real-world focus on a critically important social issue, the use of novel theory to address the research problem, and the breakthrough insights regarding the power of social bots in shaping public opinion.
