The STAR GATE scientific research of RV
Dr. Harold Puthoff founded the research in 1972 at SRI (Stanford Research Institute, now SRI International). About a year later Russell Targ joined the team. In 1976, Dr. Ed May joined the team. In 1982, Targ left SRI, and in 1985, Puthoff left SRI and May became Director. All the men are physicists.
In 1991, Dr. May's Cognitive Sciences Laboratory (CSL), which had been working via SRI, moved to SAIC (Science Applications International Corporation -- another think tank/science lab) and continued funded research there until the end of 1995, when government funding ceased. (CSL is still an active lab doing some research, but the government backing is no longer present.) CSL is now under the umbrella of the Laboratories for Fundamental Research (LFR).
The first and probably easiest 'discovery' about RV was made near the beginning: that these psychic abilities existed. Remote Viewing protocol evolved over time, as scientists refined, tightened and learned about the experimental process. As time went on, more was learned about how being psychic seemed to work, and how data seemed to affect the people getting it. Innumerable physiological and psychological tests were run on the psychics doing the data collection. At times, mass-testing of volunteers was done.
Different "methods" of getting psychic data, from traditional "psychic methods" to Swann's invented "CRV" methods (which came later in the mid-80’s) were tested themselves and against each other, to find common denominators in what made things work, what people were most likely to have ability, etc. The later research covered details about the type of data people were likely to get, the type of targets people were more likely to be able to describe accurately, potential physics theories, neurological research, multiple viewers, and more. How experiments were done, and even the methods the psychics used, varied over time. About 85% of the actual research done took place under Dr. May’s tenure as Director.
Along the way, as much was learned about the science of psychic studies as about psi itself, and parapsychology science is now probably the most tightly-controlled science around.
Only a few people involved with the psychic side of the scientific research are willing to discuss remote viewing with the public. Estimates are about half the scientific research done until 1995 is classified by the U.S. Government (and some is proprietary to others who funded it). Much of the rest is waiting for Dr. May to get around to publishing it-- there is no funding for that happening, so in the meantime, useful information about this subject resides in the heads of the team at LFR.
