When Voice Fails to Scale: Psychological Safety Climate and the Communicative Dynamics of Preventable Failure

Investigations of catastrophic failures in high-reliability systems consistently reveal that safetyrelevant concerns were identified prior to collapse yet failed to alter final decisions. Although psychological safety research has established strong associations between climate perceptions and voice behavior, less attention has been devoted to how psychological safety climate shapes the persistence and escalation of dissent under authority gradients and performance pressure. Drawing on psychological safety climate theory, organizational silence research, high-reliability organization scholarship, and the normalization of deviance framework, this paper develops a multi-level conceptual framework explaining how safety-relevant dissent becomes attenuated as it traverses hierarchical and interorganizational boundaries. The central argument is that psychological safety climate influences whether voice occurs and, more consequentially, whether it survives resistance long enough to shape collective sensemaking and decision outcomes. A mediated and moderated conceptual framework is proposed linking leader behaviors, climate formation, voice persistence, and adaptive risk mitigation outcomes. Seven formal propositions are advanced to specify the mechanisms and boundary conditions of this process. The paper reframes catastrophic organizational risk as partly communicative in origin and contributes to theory by elaborating voice persistence as a distinct and consequential construct within the psychological safety literature.
