Professor Richard Wiseman, a psychologist at the University of Hertfordshire, and a fellow of the Committee for Skeptical Inquiry (CSI) has pointed out several problems with one of the early experiments at SAIC, including information leakage. However, he indicated the importance of its process-oriented approach and of its refining of remote viewing methodology, which meant that researchers replicating their work could avoid these problems. Wiseman later insisted there were multiple opportunities for participants on that experiment to be influenced by inadvertent cues and that these cues can influence the results when they appear.
