Star Gate is the largest funded program in the history of psi research receiving about $19.933 million in funding from 1972 to 1995. Researchers from SRI International, and later at Science Applications International Corporation, in association with various U.S. intelligence agencies participated in this program.

Using the remote viewing method, research focused on understanding the applicability and nature of psi in general but mostly upon informational psi. Volume 1: Remote Viewing (1972-1984) and Volume 2: Remote Viewing (1985-1995) include all aspects of RV including laboratory trials and several operational results. Volume 3 focuses on laboratory investigations on psychokinesis. Volume 4: Operational Remote Viewing: Government Memorandums and Reports includes an analysis of the applied remote viewing program and a selection of documents that provide a narrative on the behind the scenes activities of Star Gate.

In a total of 504 separate missions from 1972 to 1995, remote viewing produced actionable intelligence prompting 89% of the customers to return with additional missions. The Star Gate data indicate that

informational psi is a scientifically valid phenomenon. These data have led to the development of a physics and neuroscience based testable model for the underlying mechanism, which considers informational psi as a normal, albeit atypical, phenomenon.

The Star Gate data found insufficient evidence to support the causal psi (psychokinesis) hypothesis.
