In human-source intelligence, elicitation is an interview technique principally for the acquisition of information from a person or group in a manner that does not disclose the intent of the interview or conversation. It is usually generally overt, unless the collector is other than he or she purports to be.  It may have a secondary purpose of preparing the subject for future interviews, not necessarily collecting information of intelligence significance, but to get a sense of the subject as a person, and also to begin a conversational relationship with the interrogator. There is an implication that some skill is required to draw out the desired information. 
Some techniques may reveal part of the intent, such as the Delphi method for eliciting expert opinion. In a Delphi panel, experts are asked questions in a manner that prevents any individual from dominating the interaction. Those conducting the Delphi study, however, may be looking for information not necessarily explicit in the questions posed to the panel.
