Humphreys' action of collecting data under false pretenses violates which principle?

The principle that is violated by Humphreys' action of collecting data under false pretenses is respect for persons. This principle emphasizes the importance of acknowledging individuals' autonomy and protecting their rights, which includes obtaining informed consent. When data is collected under false pretenses, individuals are not given the opportunity to make an informed decision about their participation, thus their autonomy is not respected.

Respect for persons also incorporates an ethical obligation to treat individuals with dignity and to honor their decision-making capabilities. By deceiving participants about the nature of the research, Humphreys failed to uphold this ethical standard, undermining trust between researchers and participants. This breach highlights the ethical importance of transparency and honesty in research practices.

In contrast, beneficence pertains to minimizing harm and maximizing benefits to participants, justice involves fair treatment and equitable distribution of research burdens and benefits, and integrity refers to maintaining honesty and truthfulness in research practices. While these principles are also crucial to ethical research, the specific violation in this scenario revolves around the lack of respect for individuals' right to be informed and make autonomous choices regarding their participation.
