“…Incomplete/improper integration of societal values with the risk assessment and/or unclear decision rules (Veland et al, 2013;Vlek, 2013a;Willis, Potoglou, de Bruin, & Hoorens, 2012) Limited debate and expert/stakeholder engagement/authorization/understanding (Bossong & Hegemann, 2016;Government Office for Science, 2012;Hagmann & Cavelty, 2012;Hilton & Baylon, 2020;Hiscock & Jones, 2017;Lin, 2018;Stock & Wentworth, 2019;Vlek, 2013a) Lack of a standard (justified and effective) risk methodology (Brody, 2020;Hagmann & Cavelty, 2012;Mamuji & Etkin, 2019;Stock & Wentworth, 2019) Methodological imprecision/confusion (e.g., around concepts of risk, probability, uncertainty, impact) (Aven, 2020;Veland et al, 2013;Vlek, 2013a) Risk and scenario selection Not all salient risks are included or considered for inclusion (post-hoc inclusion of risks evident) (Blagden, 2018;Deville & Guggenheim, 2018;Raine, 2021) Cognitive biases, groupthink, or institutional inertia obstruct valid assessment (Blagden, 2018;Government Office for Science, 2012;Stock & Wentworth, 2019) Limitations of a single "reasonable worst-case scenario" approach, e.g., omission of decision-relevant information (Bradley & Roussos, 2021;Hilton & Shah, 2021;Stock & Wentworth, 2019) Improper exclusion of uncertain, improbable, emerging, and devastating risks (Etkin, Mamuji, & Clarke, 2018;Government Office for Science, 2012;Hilton & Baylon, 2020;Mamuji & Etkin, 2019) Over focus on risk within borders rather than potentially global consequences (nationalist bias)…”
