Because social research often requires that people reveal personal information about their lives, it is essential that the researcher guarantee confidentiality and anonymity. Confidentiality is when results of a study are published, but the subject to whom the responses belong to is not revealed to the public. Anonymity is similar to confidentiality. The difference is that with anonymity, instead of only the reasearcher knowing who gave which responses, neither the researcher nor the public knows who gave which responses. These terms should not be used interchangably.
