The researcher’s failure to protect research subjects from deductive disclosure is the primary ethical violation in which studies?

The correct answer to the following question will be "Ties, Tastes, and Time (T3) ".

Explanation:

A much more prominent example of analysis that has collected personally identifiable info about people minding their own business seems to be the study or report "Tastes, Time and Ties (T3) " by Harvard (2006-2009). Preventing people from gathering reference details is a clear method of reducing the risk to the public when confidential information is unintentionally revealed.

Therefore, it's the right answer.
