Project Stargate was a classified program that ran from the 1970s to the 1990s, conducted by various U.S. government agencies such as the Central Intelligence Agency (CIA) and the Defense Intelligence Agency (DIA). Its primary objective was to investigate the potential military applications of psychic phenomena and extrasensory perception (ESP).

Under Project Stargate, a team of scientists, including prominent parapsychologists like Russell Targ and Harold Puthoff, conducted research into remote viewing, a technique claimed to enable individuals to gather information about distant or unseen targets using their minds alone. The project aimed to assess the operational viability and practicality of remote viewing for intelligence gathering purposes.

During the project's lifespan, various experiments were conducted, involving trained remote viewers attempting to describe and gather information about specific geographical locations, individuals, and events. The findings and outcomes of these experiments were evaluated by the intelligence community to determine the usefulness and reliability of remote viewing as an intelligence tool.

While Project Stargate received both support and skepticism, the program officially concluded in 1995, with the CIA releasing declassified documents related to the project. The documents indicated that remote viewing had shown some promising results but were inconclusive in terms of its overall effectiveness as an intelligence tool.

Project Stargate remains an intriguing part of the history of psychic research and the exploration of unconventional avenues for intelligence gathering. Its legacy has sparked ongoing debates about the boundaries of science, the potential of the human mind, and the role of such unconventional methods in the field of intelligence.
