What are the different "types" of remote viewing?
In this case we’re using the official term remote viewing, so this describes different ‘types’ of RV as commonly known in the science community.
The Ganzfeld approach to remote viewing uses a mild form of sensory deprivation, in the hope that minimizing input from the world around the psychic or remote viewer will maximize their ability to sense subtle input from their subconscious/psi. Usually the psychic is reclining or lying down. Halved ping-pong balls are placed over the eyes, and the room has a dim red light. White noise is usually played through a speaker. Ganzfeld RV data often seems a bit 'dreamy'. This may be due to the rather hypnagogic nature of the methodology.
"Outbounder" or "Beacon"
The Outbounder approach to remote viewing uses a second person as a 'beacon' for the psychic or remote viewer. The viewer sits in one location, and the outbounder leaves the building, gets in a car and drives around randomly for a specified period of time. Then the outbounder opens a sealed envelope with directions to the target site. At an appointed time, the outbounder is to be standing at the target site taking note of his surroundings. The viewer's job is to describe the surroundings of the outbounder. Eventually it was found that (a) it’s pretty much impossible to separate ‘telepathy’ from ‘clairvoyance’ in testing, and (b) outbounder sessions are no better than regular RV and sometimes can be worse (based on viewer AOL), so this is seldom if ever done in formal RV science nowdays.
Associative remote viewing is a protocol based on a revised tasking for a given RV project. It is used for binary targets (where there is a choice of two outcomes (plus ‘other’), and these types of targets are usually also a form of precognitive psi. The tasker "associates" three specific targets with the outcomes in question. When tasked, the Viewer's description will (it is hoped) match one of those targets clearly enough for the tasker to conclude an answer. For example, if the target is the rise or fall of the price of sugar on the commodities market tomorrow, the tasker may assign "Niagara Falls" to a "fall" answer, "the Eiffel Tower" to a "rise" answer, and "the grand canyon" to "other" (such as, stays the same, the stock market is closed that day, or any other potential).
The viewer is tasked with, "Describe the target." If the Viewer's description can be correlated with one of the predefined associated targets, that is what the analyst or tasker would take as the psi-derived "answer." When the outcome is learned, the viewer is given the feedback of the target correlated with the actual outcome. They are not given feedback on the other options or on what they may have described, even if it is clearly one of the other selected targets.
Coordinate RV is a standard RV protocol but used with the initial "tasking" of geographical coordinates (or ‘encrypted’ coordinates) for the target. The initial RV research had a very serious question to answer about how you could direct a psychic to describe a given thing if you could not tell them what it was they were supposed to be describing. Ingo Swann is credited with coming up with the geographical coordinates concept, which was used for some time. Some scientists proposed that a viewer might have memorized all the millions of planetary coordinates and what was at their location (in detail), so this eventually caused the science to ‘encrypt’ the coordinates. This later changed to simply being a string of random numbers, and then sequential numbers mostly used for proper tracking/databasing of sessions. It was found that a simple "describe the target" tasking was sufficient for ‘direction’.
Note: In the case of Coordinate, Outbounder and Associative remote viewing, these approaches could be used in conjunction with most any psychic methodology. Ganzfeld is more limited to use in conjunction with methods due to its altered state/visually secluded environment.
Psychic Methodologies often used in conjunction with Remote Viewing Protocol
Be aware that a methodology does not ‘make’ a process remote viewing. A method used within a proper remote viewing protocol makes it remote viewing.
"Controlled" Remote Viewing (CRV)
In the early 1980's, psychic/author/artist Ingo Swann began compiling a set of psychic methods which he felt addressed the important aspects of psychic work. These methods were designed to be used within an RV protocol, and as such, were referred to as as form of remote viewing. Based heavily on the work of French researcher Rene Warcollier, and combining theories from his own interests in a wide variety of fields, Swann’s methods were a how-to for communicating data one receives via psi. The methods are utilized while sitting at a table and writing or sketching data. They are notable in that they are done in a far more "alert" state than many other approaches to collecting psi information.
In a historical sense, these methods are considered by some to have been Swann’s attempt to teach people to pay attention to how they processed data, and as such were training methods -- NOT viewing methods, and according to documentation even at the time, were not designed to be used outside a proper RV protocol even in training after Stage III.
However, historical revision has now gone so far in "RV Methods" and their origins, values, intents etc., that it’s a subject best left alone. There are a variety of people teaching a variety of versions of these methods. Swann denies all credit or blame for their current incarnations.
"Extended" remote viewing (ERV)
One of the more common means of "getting in touch with a target" is similar to the Ganzfeld approach, but without the technology. In this instance, usually the psychic reclines or lies down comfortably in a dim or darkened room, and another individual (an 'interviewer' or 'monitor') asks them questions and records the data they verbally provide, or they use a tape recorder. Prior to finishing their session they generally attempt to sketch their impressions. This has probably been a method used by psychics throughout time.
In the later years of the DIA intelligence unit that utilized remote viewing, once CRV (above) had become a standard methodology, the "natural psychic" way of going about things was coined the term ERV, mostly to separate it from CRV (and as such, it encompassed most anything CRV was not). Over time, as the viewers had been bred into the concept of ‘methods’, various methods were imposed upon this approach as well, until it was a slightly different creature.
At this point, there is no legitimate claim by anybody to know ‘what ERV really is’, but there are a variety of people who have done something like this, at some time, some of them in the intell unit, some initially and some after CRV came along and caused the ERV-term to be coined-- and they are probably all doing something different-yet-similar. There are people who ‘teach’ ERV methods in the public now, based on what they think they know about the intell Unit’s use of ERV. It probably doesn’t matter. In the end, methods are just methods -- if you work within protocol and get accurate data, you’re doing alright.
Mostly thanks to the internet and remote viewing being a money-making opportunity, there is now a wide variety of ‘training’ available for what many people call ‘remote viewing’. Whether it works within the real RV protocol, you’d have to investigate. Whether it is a derivative of Swann’s CRV, you’d have to ask. Whether its form is worthy of study let alone payment, is something I can’t answer. There are other individuals from the military who have some experience with psi work there, such as David Morehouse, Ed Dames, and Glenn Wheaton, who do not teach CRV but teach their own version of either CRV, ERV, or in Glenn’s case something else entirely.
