In the context of human research protection, which is true about consent?

Informed consent is a foundational principle in human research protection, emphasizing that participants have the right to understand what they are agreeing to before becoming involved in a study. This concept is essential for upholding the autonomy and dignity of individuals participating in research. When all research involving human subjects is treated with the necessity of obtaining informed consent, it ensures that participants are adequately informed about the purpose, duration, procedures, risks, and potential benefits of the research. This process not only protects the rights of the participants but also enhances the integrity of the research by promoting transparency and voluntary participation.

The idea that consent can sometimes be waived, while valid in specific circumstances, does not negate the general requirement that informed consent is crucial for most research projects. Thus, recognizing the need for consent in all research involving human subjects reinforces ethical standards and legal frameworks that protect individuals in a research context.
