Answer :
The principle of study ethics that resulted from the infamous Tuskegee syphilis experiment is **informed consent**.
1. **Explanation:** In the Tuskegee syphilis experiment, researchers conducted a study on African American men without their informed consent. This unethical study led to the establishment of the principle of informed consent in research ethics.
2. **Informed Consent Definition:** Informed consent is the process where participants are provided with all relevant information about a study, including its purpose, procedures, potential risks, and benefits. Participants must voluntarily agree to participate based on this information.
3. **Importance:** Informed consent ensures that participants are aware of what they are getting into and have the autonomy to make an informed decision about their involvement in a study. This principle protects participants from being coerced or misled in research studies.
4. **Example:** If a researcher wants to conduct a study on a group of individuals, they must provide detailed information about the study, answer any questions participants may have, and obtain their explicit consent before involving them in the research.
In conclusion, informed consent is a crucial ethical principle in research that safeguards the rights and well-being of participants, a lesson learned from the unethical Tuskegee syphilis experiment.
