Which ethical issue requires that trust/mind/body will not be invaded and can be dealt with by providing anonymity?

The correct answer is privacy because it specifically involves the individual’s right to control their personal information and make decisions about which aspects of their mind, body, and personal life they are willing to share. Providing anonymity ensures that sensitive data about a person's experiences or participation in research remains undisclosed, thus protecting their privacy.

In research and psychological practice, privacy safeguards help to build trust between participants and researchers, as individuals are more likely to participate fully when they know their personal information will not be revealed. This emphasis on personal autonomy and control over one's intimate details reflects the core concern under privacy.

Confidentiality, while related, pertains specifically to the obligation of researchers to protect the information shared by participants and not disclose it without consent. Informed consent involves ensuring that participants understand the nature of the research and voluntarily agree to participate, without coercion, which may overlap with privacy but is not directly about the control of personal information. Deception refers to misleading participants regarding the true purpose of the research, which raises ethical concerns but is not about the protection of privacy.
