A criterion for waiving informed consent is that, when appropriate, subjects are provided additional pertinent information after the study. Which studies would it not be appropriate to provide subjects with information?

Explanation:

An example of a study where it would not be appropriate to provide the subject with such information would be a study in which the individual subjects have been specifically assigned to study activities solely based on a specific undesirable or unflattering physical characteristic that has been previously assessed by the members of the research team. This would not be appropriate as it is not necessary information that affects the individual by withholding it. Instead, it can hurt the individual emotionally by providing this information to them.
