Respect for persons
People taking part in research are treated as individuals who make their own decisions. That is why studies ask for voluntary, informed agreement instead of assuming it.
Extra care is expected for people whose ability to decide may be limited, so their interests are protected without removing their voice.
Beneficence: weighing benefits and risks
Researchers are expected to reduce possible harms and to make sure any risks are reasonable compared to what the study hopes to learn.
Good risk communication explains what is known, what is uncertain, and what participants can do if something feels wrong.
Justice: fair selection and fair burden
The burdens and benefits of research should be shared fairly. Groups should not be chosen simply because they are easy to reach or less likely to ask questions.
Why history matters
Modern protections grew out of serious past failures in research conduct. Codes and reports written in response set the expectations that review boards still apply today.
