Special protections for vulnerable communities
Respect "involves providing for the protection of those with diminished or no autonomy as well as empowering them where possible and protecting and helping people wherever it would be wrong not to do so."
Vulnerable groups include those who lack capacity for informed consent, those who are subordinate members of a hierarchical group.
Dealing with vulnerable communities requires particular sensitivity. Sometimes community representatives can help researchers recognize the unique decision-making processes of individuals and communities and suggest the best ways to empower participants to make voluntary decisions. Doing research with vulnerable communities requires particular care in research design which will be carefully studied by Research Ethics Committees.
