This information may be valuable in answering collection requirements or may give the [human intelligence] HUMINT collector insight into the viability of other approaches.
A real or imaginary deficiency voiced about the source, loyalty to his organization, or any other feature can provide a basis for this technique.
An example of this technique is opening the collection effort with the question, "Why did you surrender so easily when you could have escaped by crossing the nearby ford in the river?"
The source is likely to provide a basis for further questions or to reveal significant information if he attempts to explain his surrender in order to vindicate himself.
The objective is for the HUMINT collector to use the source's sense of pride by attacking his loyalty, intelligence, abilities, leadership qualities, slovenly appearance, or any other perceived weakness.
