“…It's…they're silly… (Paul, policy)This finding is consistent with findings in other areas of policy uncertainty, where policy actors were found to hold “paradoxical positions” where they both privilege the authority of risk‐based policy approaches, while concurrently acknowledging quantitative risk analysis as having a constrained role (Duckett et al ; Mouter, Annema, and van Wee ). The issues with cost–benefit analyses described by these participants are similar to those identified by Mouter, Annema, and van Wee () as “intangible effects.” Intangible effects are effects for which it is difficult to determine: causality between a course of action and an effect, whether the effect will occur and/or whether the effect is beneficial or harmful for national welfare (Mouter, Annema, and van Wee , 280). Good public policy must recognize the limited capacity for economic instruments to determine policy priorities in complex, competitive, multi‐stakeholder areas, and not succumb to the temptation to simply bracket‐out the inherent uncertainty through exclusive use of apparently “rational” risk‐based approaches (Duckett et al ), which themselves are value‐laden (Meghani and Kuzma ).…”
