What would be interesting is a look into passive elicitation of information. Its easy to falsify something when you know someone is looking to use a single data-point against you. But tryly powerful social engineering would manipulate your confidence, and extract high-information-content data passively (when you are not expecting it), and to do this they need to instill confidence that you <are not being ovserved or monitored>. Yet they still may need to promt information flow, to feed the analysis. Which is sort of the art of interviewing, but now in a bit more 21st century context.
