A researcher is studying how deductive disclosure of identity may occur in a data set. The primary ethical violation is in which study?

• A. The Tastes, Ties, and Time (T3) study
• B. The Tearoom Trade study
• C. The Background Noise study
• D. The Helmet safety observation study

Answer: (A)

Deductive disclosure means that even after removing obvious identifiers, a person can still be identified by combining the remaining data with outside information. In studies like this, the ethical concern isn’t just about whether names are shown; it’s about whether the data could be used to re-identify someone in the real world. The Tastes, Ties, and Time (T3) study involves highly granular, longitudinal data about individuals’ preferences, social connections, and activity timing. This kind of rich, individual-level information can create a unique fingerprint. When researchers release or share such data, someone might cross-reference these patterns with public or external sources to deduce who a participant is, which violates confidentiality and raises serious privacy concerns. That susceptibility to re-identification captures the essence of the primary ethical issue described. While other studies raise important ethical questions—such as informed consent and deception in the Tearoom Trade, or the ethics of observation in other contexts—the scenario described centers on the risk that data could reveal identities through deduction, which is most clearly illustrated by the T3 study.
