Technology has outpaced the capacity of researchers performing research on human participants to interpret all data generated and handle those data responsibly. This poses a critical challenge to existing rules governing human subjects research. The technologies used in research to generate images, scans, and data can now produce so much information that there is significant potential for incidental findings, findings generated in the course of research but beyond the aims of the study. Neuroimaging scans may visualize the entire brain and (...) even the entire head; computed tomography colonography research may visualize the entire torso, from the base of the lungs to the pubis; genetics studies may reveal “extra” and sometimes unwanted information about the family, such as misattributed paternity and undisclosed adoption; and genomic microarray research increasingly involves whole-genome analysis revealing an individual’s complete genotype, with enormous potential for uncovering unexpected information about an individual’s genetics and risks of developing future conditions.
