Boeing researchers don't just spend their days designing planes, killer drones and networked tanks. They also investigated unexplained powers of the mind, especially in the late 1960s.

This study, New Correlation Between a Human Subject and a Quantum Mechanical Random Number Generator, conducted in 1967, "tentatively conclude[s]" that people can basically will particular numbers to appear. According to the Boeing-ites, there "exists a weak but significant correlation" between the experiment's "statistical processes" (that would be the generation of random numbers, "connected to four lamps and four corresponding pushbuttons") and "the experimenter who initiates the processes" ("the human subjects, asked to press the buttons... with the objective in mind of obtaining a high number of coincidences").
The study does not mention any follow-up studies. But this Boeing experiment is one of a number of fringe and alternative science projects that are available at the online archives of the Defense Technical Information Center.

Here are three more examples: Group Norms and Dissonance Reduction in Belief, Behavior, and Judgment: "Forty-four female subjects met in groups of four, each in a separate booth, and were asked to report whether or not they received 'ESP images' which were presumably projected by a 'sender' in another room," during this 1960 military-backed study at UCLA. "Half the Ss, in a control condition, were unaware of the responses of others. For the others, in the experimental condition, a device... gave each subject the impression that the other three Ss had received images on 23 of 30 trials. It was found that, particularly, in the control condition, reported reception of ESP images was a function of one's initial belief in ESP."
And: An Analysis of the Relationship Among Meditation, Personality Type and Control of Brain Wave Production: "In recent years scientists in every nation have come to realize that voluntary control of behavior is of primary importance if one hopes to establish an ordered society or even to maintain a society. Meditation has been known and practiced by Asian people, especially Indians, for many hundreds of years," notes this 1973 paper from the Naval Postgraduate School. "With the aid of the biofeedback technique, it is believed that the study of altered states of consciousness, creativity, parapsychology, personality type, psychosomatic medicine, therapy, and education, etc., could be greatly enhanced."
And: Photon Quenching of the Paranormal (Time) Channel (and others): Lt. Col. Thomas Bearden started out, in this 1974 study for the Army Medical Intelligence and Information Agency, "searching for a way to break the deadlock in which physics, mathematics, and philosophy are all entangled."
By the time 1976 rolls around, he's advancing: - a fourth law of logic together with the first three Aristotlean laws of logic form a complete, closed metalogic encompassing both physics and metaphysics. A cluster of an infinite number of orthogonal 3-dimensional spatial frames, all containing the same single fourth dimension, or time axis, provides a framework onto which mind, matter, fields, being, life, and both physical and metaphysical phenomena can be fitted and precisely modelled. Thus metaphysics can be precisely modelled by, and related to, physics. A mind becomes a complete 3-dimensional physical world. From the model, constructs that model life, death, a biological system, psi, consciousness, inception, telepathy, psychokinesis, UFO's, God, and the collective unconscious can be taken. Materialization, dematerialization, and mind linkage also exist, as does a specific mechanism for tulpas (materialized thought forms)."

It is clear that some of these studies predate the 1972 Remote Viewing experiments that the CIA launched at SRI in California. The "hope" and "tentative conclusions" that were reached in the 1960s, seem to have contributed to the launch of a larger research project. Boeing and others thus seem to have provided thrust and take-off to official psychic studies.
