“…Several studies have contributed innovative additions or alterations to the ACF related to the topic of the roles of experts and expert‐based information and/or presented amended or additional hypotheses. These studies have covered themes such as the further characterization of types of advocacy coalition actors (e.g., Heintz & Jenkins‐Smith, 1988; Witting & Dudley, 2019); the dynamics of expert‐based information within different types of policy subsystems (e.g., Rietig, 2018; Weible, 2008; Weible, Pattinson, & Sabatier, 2010); the impact of expert‐based information versus political dynamics on policy subsystems (e.g., Fischer, Ingold, & Ivanova, 2017; Lodge & Matus, 2014; McDougall, 2016); and whether or not experts behave as neutral actors in policy processes (e.g., Ingold & Gschwend, 2014; Lodge & Matus, 2014; Montpetit, 2011). Some studies also question perceived existing shortcomings and contradictions within the ACF (e.g., James & Jorgensen, 2009; Montpetit, 2011; Weible & Sabatier, 2005) pertaining to the topic of experts and expert‐based information.…”
