Nick Pope: Traditional methods of gathering intelligence include using satellites, intercepting communications and recruiting agents. Now, secret documents have emerged revealing that the Ministry of Defence ran a covert project to recruit psychics, in the hope of tracking down people and items of interest to the government and the military.The technique is known as remote viewing and a search for the phrase on Google reveals nearly a millions hits. Remote viewing is a technical term, but what it really means is trying to use psychic ability - extra-sensory perception - to find things. Uri Geller claims to have undertaken work for companies keen to see if he can help them locate previously unknown oilfields and mineral deposits. But the technique has also been used by intelligence agencies, though details of the British study have only just emerged. The term remote viewing was coined in the Seventies by researchers at the Stanford Research Institute, in America. Their work soon attracted the attention of US intelligence officials. The Americans knew that the Soviets were studying parapsychology and were worried that the USSR might make a breakthrough in an area where the US had no expertise. In the language of risk management, this was a classic case of "low probability/high impact". There was no corporate belief in ESP, but if the technique worked and could be used by the government, the potential benefits were huge. And if somebody else got there first, the consequences were unthinkable. Both the Pentagon and the CIA funded remote viewing programmes, which went by codenames that included Grill Flame, Sun Streak and Star Gate. A few documents have previously been released under the US Freedom of Information Act and some of the former remote viewers have spoken out about their government work, which included searching for hostages, arms dumps, drugs caches and terrorists, as well as attempting to identify the location of Soviet ballistic missile submarines.
