Deception in research is contentious, as ethical codes stress informed consent, yet complete disclosure may jeopardise validity. Indian Council for Medical Research (ICMR) guidelines classify deception into active, incomplete, and authorised forms. This study explores the ethical justification for incomplete (partial disclosure), permissible instances, and the dilemma faced by ethics committees in balancing scientific rigour and participant protection. The qualitative, non-experimental cross-sectional research, using in-depth interviews, identifies themes through thematic analysis. Findings reveal challenges for ethics committees, as incomplete information hampers (...) understanding, amongst others. The paper proposes an ethics committee framework, urging researchers to minimise or avoid partial deception and recommending institutional awareness campaigns and standard operating procedures for minimal-harm studies using partial disclosure. Therefore, it proposes that partial disclosure should be justified by the 3Vs—value, validity, and veracity to preserve research integrity. (shrink)
