What is a fundamental aspect of the Nuremberg Code regarding consent?

The fundamental aspect of the Nuremberg Code regarding consent is that subjects should have the legal capacity to give informed consent. This principle emphasizes the protection of individuals who participate in research by ensuring that they are fully aware of the nature, risks, and benefits of the study. It recognizes the necessity for participants to understand the implications of their involvement and to make voluntary choices without coercion or undue influence.

Informed consent is not only about having permission but also about ensuring that the individual is competent and capable of making such decisions, which includes being of legal age and having the mental capacity to understand the information provided. This principle is central to ethical research practices and is a foundation for protecting participant autonomy and rights.
