Stories of spirits, ghosts, demons, and encounters with otherworldly entities abound throughout the histories and literature of literally every culture the world has ever produced. Tales of helpful spiritual guardians, spiteful faeries, and vengeful wraiths figure prominently in many ancient stories. And they continue to be a topic for which modern man holds at least some fascination, given the number of movies released each year which deal with encounters with the supernatural. However, beyond the entertainment one may enjoy by telling ghost stories around a campfire, there is truly fascinating research being conducted into the realms of what is usually termed 'supernatural'. Researchers have, for more than a century, sought to plumb the depths of the unknown to find out what may lie beyond the cessation of life in the physical body. The first organized body of researchers to band together and apply scientific techniques to the study of ghost phenomena was the Society for Psychical Research. Formed in 1882 by a group of distinguished Cambridge scholars, they immediately set about trying to formulate and prove theories on all subjects relating to the paranormal, including telekinesis and clairvoyance as well as haunting activity. Unfortunately, many of the early SPR members seemed to be too gullible, wanting desperately to believe the claims of many so-called mediums and psychics. This led to the downfall of many researchers, with the credibility of the SPR being severely damaged as a whole, when most of the charlatans who had been declared genuine by the Society later were shown to be fraudulent. Ironically, it was one of the SPR's own founding members, Harry H. Price, who debunked so many of the supposed psychics. These included psychics who Price himself had originally declared to be genuine. This unfortunate chain of events lead to an inevitable schism between Price and the SPR, a side effect of which was that much of Price's research faded into obscurity. However, we now apply many of his theories and research methods to ghost hunting, marrying century-old theory with modern equipment and scientific knowledge.
Modern evidence gathering can take many forms. Many interesting, possibly
even bizarre, investigative methods have been tested over the decades
that modern paranormal research has existed. Most have fallen into disuse;
the results, when there were any, were either too unreliable or completely
unverifiable by any other researchers. However, a few methods have withstood
the test of time. Probably the most effective, and yet most problematic,
method employed is that of so-called ghost photography. One of the most serious problems paranormal researchers encounter is that of hoaxes. Most published 'ghost' photos are either deliberate falsehoods, or mistakes made by well-meaning but uninformed private enthusiasts. The most common form they take is that of the visibly bizarre but explainable double exposure. Simply put, when a photographic frame is exposed twice before picture development, then a strange 'otherworldly' double image may be obtained. Usually, these are easy to spot, even for the photographic novice. However, at times they can occur and look so authentic that even longtime researchers are fooled. Of course, photographic artists and experts can look and immediately see the underlying cause of the strange photo. This has the unfortunate effect of destroying ghost photography as a credible source of evidence, leading many skeptics to fallaciously assume that all ghost photos are tricks of light, shadow, over, under, and double exposure. Luckily, we now have new tools in our photographic arsenal. Digital photography, and the privately affordable digital camera, has been of great use to the modern ghost hunting community. With digital photos, double exposures are nearly impossible. Likewise, as there is no developing process, development errors or flaws on the film can no longer happen. And most digital cameras can see quite far into the IR and UV portions of the spectrum. An easy test of a camera's capability is to simply aim a television remote at the lens and observe on the device's screen when one presses the volume button. The IR light emitted by the remote control will be visible on the camera's screen. Another extremely useful tool is the IR capable camcorder. Most major
manufacturers of domestic electronics have at least one or two camcorders
that are "night vision" capable (i.e. The Sony NightShot). These
infrared enabled recorders have a small emitter on the front of the camera.
While the range of these emitters is generally limited to no more than
10 feet, special extension devices can be purchased which easily extend
the IR beam to more than 80 feet. With these cameras, phenomena have been
recorded which are very difficult to attribute to a mundane source. When
operating multiple cameras under strict usage guidelines as per the manufacturer's
operating instructions, mistakes can be nearly eliminated. They were designed to measure manmade electrical fields within certain frequencies. Those frequencies almost always center on 50Hz to 60Hz, which are the frequencies of the electrical grids in Europe and North America, respectively. Some EMF meters can see further below 50Hz. A popular model is able to measure between 5Hz to 60Hz. But while most ghost hunters can tell an interviewer that it is important to register a wider range of EM frequencies, they cannot answer why it is. Most don't know that the frequency most often associated with haunting activity is centered on 40Hz, and is never an Alternating Current field, or manmade AC electricity. It is always Direct Current, or a natural DC electromagnetic field. I believe this is because the human mind's "operating system", if you will, registers as a DC electromagnetic field operating at or near 40Hz. So, the EMF sensors most ghost hunters utilize are not even capable of registering a ghostly energetic field, and what results they do get are almost always caused by manmade interference. Another very commonly used method of investigation involves the employment of mediums or psychics. Many groups use "talents" in the course of their investigations to flesh out the sometimes-sketchy information available on the possible consciousness that inhabit the area under research. However, there is a vocal minority within the ghost hunting community that objects to the use of data gleaned from the use of these often self-proclaimed mediums. Simply put, not one single experiment in modern research has ever been able to conclusively prove the psychical talents of these so-called mediums. Worse still, many mediums appear to be in the field solely for the easily obtainable funding they can accrue from fleecing an unwary and gullible public. As a scam, it has it's attractions: the general public wants to believe in ghosts, and will have almost no means of proving that they've been fooled by a con artist. Certain ghost hunters have taken it upon themselves to offer their services, free of charge, to anyone who is considering hiring a psychic or medium. Their offers usually involve thoroughly investigating the supposedly haunted location to see if there is even anything there for the medium to "cleanse". Very often, there is not. The phenomena experienced by the subject most often have mundane causes, which the frightened person's mind then expands upon, in a process, which is self-sustaining and gets worse over time. Indeed, it is our perceptions of our environment, which seem to fuel most
haunting activity. Most often, "ghosts" are nothing more than
the intrusion of subconscious fears impinging upon our conscious thoughts. However, while this may explain the vast majority of ghost sightings, it does not explain them all. Interestingly enough, perception plays a very important role in actual ghost activity as well. Based upon the research of Dr. Michael Persinger at Laurentian University, scientific ghost researchers (spearheaded by the Southwest Ghost Hunters Association,) have formulated a theory of ghost to person interaction that appears to explain the mechanics of the vast majority of ghost sightings. Dr. Persinger founded the Behavioral Neuroscience Program at Laurentian
University in Ontario, Canada. The program's research centers on the specific
interactions between the human mind and different electromagnetic fields,
in an attempt to explain otherwise mysterious sightings. In Dr. Persinger's
own words, "As a human being, I am concerned about the illusionary
explanations for human consciousness and the future of human existence.
Consequently after writing the Neuropsychological Base of God Beliefs
(1987), I began the systematic application of complex electromagnetic
fields to discern the patterns that will induce experiences (sensed presence)
that are attributed to the myriad of ego-alien intrusions which range
from gods to aliens."
(Internet, http://laurentian.ca/neurosci/_people/Persinger.htm) The findings of Dr. Persinger's group have direct relevance to the field of ghost hunting. He has shown that the application of low frequency electromagnetic fields to human volunteers can induce hallucinatory states. His subjects reported feelings of euphoria, engaged in conversation with deceased relatives, and even experienced alien abduction scenarios. In many cases, the field frequencies used in research experimentation were the same as those found in anomalous "rogue" electromagnetic fields associated with haunting activity. So, it is possible that the vast majority of ghost sightings were purely perceptual, the witness having been manipulated by the electromagnetic energy of the anomaly to perceive whatever the ghost wanted the witness to perceive. Consequently, while human witnesses may behold a horrifying, grisly apparition, all that are captured by photographic equipment are the quite mundane appearing orbs, mists, and other photographic phenomena most commonly associated with ghostly presences.
