In the practical application of remote viewing as a tool for information gathering, the question of the reliability of the information is important. The results of a session are never 100% correct, so what information can you rely on? After all, real-world applications are open questions that no one can pull a photo out of a closed envelope to clarify.
In the days of the Stargate program, viewer information never stood alone, but was supplemented by and cross-checked with other intelligence information channels.
In today’s civilian application, the problem is different, because to reconcile the open questions, in most cases only further RV sessions are possible. First of all, it is obvious: What several viewers (blindly) bring in matching information is most likely correct.
A small but noteworthy footnote to this logic is the unanswered questions about the theory of the “telepathic overlay” as described by Ingo Swann in an essay dated Feb. 4, 1996.  Many remote viewers have already presented their experiences and views on this, but to our knowledge there has not yet been any scientific evidence. Some claim that the phenomenon does not exist, others attribute the theory to practical experience. Paul H. Smith thinks that telepathic overlay could most likely be a topic of the Tasker, especially when it comes to non-existent or very emotionally charged targets, such as in the esoteric area. In this way, the personal assumptions of the tasker could be picked up by the viewer if the viewer does not get a suitable signal from the actual target.
