Jones' Dilemma: Named for British scientist Reginald Victor Jones, who played an important role in the Allied effort during World War II, the Jones dilemma indicates that the greater the number of intelligence and information gathering and transmitting resources available to the deception target, the more difficult it is to deceive the target. Conversely, the more of the target's intelligence and information systems that are manipulated in a deception plan or denied to the target, the more likely the target is to believe the deception. One reason the World War II Operation Bodyguard deception was accepted as true on the German side is that Germany's ability to acquire information about activities in England was limited, enabling the Allies to manipulate the few German intelligence gathering resources that were available.
