To understand this important information, it is necessary to know who uses this tactic and on whom it works. If an unaware person is told a part of the truth (it is imperative that the answer embody truth), he is satisfied that his query has been answered. If an aware person (one who himself uses the stratagem) is given an answer which is truthful but bears only slightly if at all on the question, he knows that the information he seeks is of a private nature and will not be handed to him willingly. Thus direct denial, lying and the revelation of personal affairs are avoided.
