I explore the link between the emergence of organized secret resistance to change and the stabilization of organizational identity - operationalized as the core theory (developed by Freud) upon which the International Psychoanalytic Association was founded. In this longitudinal qualitative case study, I investigate the actions of Freud’s Secret Committee that resisted three successive change attempts by IPA’s most senior members between 1910 and 1914. This paper advances three research questions: (1) Why this group resorted to secret actions?; (2) How were secret actions used to achieve its goal?; (3) What were the organization-level outcomes of secrecy? The findings establish that reputational concerns and fears for organizational survival drove the group’s actions from open resistance to formalized secrecy, to routinized secrecy. Secrecy was instrumental for resisting change by neutralizing the change agent’s resource (formalized stage) and seizing political control of the organization (routinized stage). Finally, I demonstrate that organized secrecy stabilized organizational identity in the long-term by suppressing exploration in favor of exploitation. By contributing to the literature on resistance to change and organizational identity, this paper calls for a less normative and more nuanced understanding of intra-organizational secrecy.
