Informed Consent in Research

Informed consent is the cornerstone of ethical human subjects research, requiring researchers to disclose material information about a study and obtain voluntary agreement from subjects before participation. Established as the first principle of the Nuremberg Code (1947) and formalized in subsequent ethical frameworks (Declaration of Helsinki 1964, Belmont Report 1979), informed consent protects subject autonomy, enables risk-benefit assessment, and creates accountability. Effective informed consent requires far more than obtaining a signature—it demands clear communication, genuine comprehension, and authentic voluntariness.
