This paper argues that public sector organizational failure may be best understood from a perspective of collective denial. The rise of this phenomenon is examined using testimony from a Public Inquiry into the downfall of a UK hospital, where falling organizational standards led to unethical decision making and an unacceptable number of patient deaths. In this paper, we show how collective denial, over time, became a process that resided within the fabric of organizational life. To explore the organizational processes associated (...) with collective denial, and how and why it occurs, we identify the influence of a ‘narrative of silence.’ This narrative allows ever more serious failings to be justified as organizational members lose contact with reality entering a downward spiral with no recovery. The combined impact of assumptions about leadership capability, enculturated professional identities, and organizational loyalty create an environment where a narrative of silence can develop.
