It was based on information released by Stephan Schwartz, one of the architects of Project Stargate and remote viewing from a study he conducted using dozens of remote viewers to make accurate predictions of the future. You see, when you remote view the future, it's even less accurate on average than remote viewing an object in the present or past because of multiple possible futures, so you need lots of subjects remote viewing the same time and place to refine the overall likelihoods of certain events occurring in any given timeline. If multiple viewers don't corroborate some of the findings, then they are either less likely to occur, or they are inaccurate interpretations based more on overlay than remote extrasensory prediction.
