What is an example of risk from inadequate protection of confidentiality?
This is a crucial topic and a complex one. For example, asking demographic questions that are not essential for the purpose of the research may unnecessarily allow some participants to be identified by their responses to those questions even if the research is otherwise anonymous. See Level of Risk: Inadequate Protection for the Confidentiality of Research Data on page 7 of Policies and Procedures for more information on this topic.
