“…Thus, the question to be investigated is how members of a research group should update on the receipt of new evidence in a social setting, where they also have access to relevant beliefs of (some or all of) their colleagues, supposing the group wants to strike the best balance between speed (getting at the truth fast) and accuracy (minimizing error rates). The main methodological tool to be used is that of computational agent-based modelling, which has become a central topic in artificial intelligence (Shoham, Powers, & Grenager, 2007;Tamargo, Garcia, Falappa, & Simari, 2014;Nunes & Antunes, 2015;Gottifredi et al, 2018). Specifically, we build on the well-known Hegselmann-Krause (HK) model for studying opinion dynamics in groups of interacting agents focused on a common research question (Hegselmann & Krause, 2002, 2005, 2009; for related models, see Deffuant et al, 2000;Dittmer, 2001;Weisbuch et al, 2002;Pluchino, Latora, & Rapisarda, 2006;Semeshenko, Gordon, & Nadal, 2008;De Langhe & Greiff, 2010).…”
