Oncologist did not disclose 70% mortality rate to IRB. Which ethical principle violated?

The principle of justice pertains to fairness in the distribution of benefits and burdens in research. While the oncologist's actions may have implications for justice, the immediate ethical violation here is not about equitable treatment or distribution but rather about honesty in disclosing essential information.

A conflict of interest occurs when an individual's personal interests could potentially compromise their professional judgment. Although the oncologist's failure to disclose may suggest a potential conflict, the primary ethical breach in this scenario centers on the lack of truthfulness regarding the mortality rate rather than a direct conflict of interest.

Beneficence is the ethical obligation to act in the best interest of the patient or research participants. While failing to disclose the mortality rate may impact patient welfare, the core issue at hand is the lack of honest communication. Thus, the violation of beneficence is secondary to the more direct violation of veracity.
