I got a package in the mail from Amazon around the time of my birthday. It was light, not a book, something from my Wish List. I had my very own ghost meter! I started roaming my house looking for sources of electromagnetic fields.
If I just let my ghost meter sit there, it does nothing. But if I find a known source of electricity, then the analog meter bounces upward or, in some cases, pegs all the way to the right causing a flashing light and beeping sound. Around the house, here is what sets it off—the circuit box, the electronic displays on the oven and dishwasher, my digital alarm clock, the microwave, toaster oven and dehumidifier when turned on. No surprises there. My cell phone didn’t trigger it. I tested it outside with an approaching lightning storm. It was slightly greater than 0 milligauss outside compared to inside, and varied slightly from front of the house to back of the house. The storm never got close enough for me to record electromagnetic fields (EMFs) fluxes from lightning discharges. That probably was a good thing because I would have been standing out there in a rather dumb position, you know, for science.
My questions about this device were many and varied. What was it really measuring? Was it telling me anything? And, most importantly, what does this have to do with ghosts?
Earlier this summer, during a ghost hunt in which I was an observer, I saw paranormal researchers each with their own kinds of EMF meters. Some meters registered a change in the surrounding field at the same time. Some individual meters would fluctuate with no apparent electrical sources. The researchers considered these fluctuations to be indicative of responsive entities or paranormal energy around us. It was assumed that these anomalies were paranormal.
Where did this idea come from—this connection between EMFs and ghosts? It looks sciencey and objective. But something is not on the level. I consulted more knowledgeable people and the parapsychology literature to get some clarity on this issue.
There is Science Behind These Devices
My meter was cheap but was noted by reviewers as being a “good beginner device”. Just don’t wave it around too fast, they said, because that makes it go off.
I asked former physicist and one-time paranormal investigator on the Queen Mary “haunted” ship, Yau-Man Chan, what the deal was with these devices. He said they are simple to construct, very straightforward. They are an inductor coil and an amplifier. They pick up “impulsive” EMF signals, like a large inductive load turning on and off—an appliance with a motor, for example. Elevators, he notes, are a huge source of EMF signals like this. But because these hand-held meters are not specific enough in direction or frequency, they aren’t very useful for much and not at all precise enough to conclude what is detected if it’s not obvious. Electricians don’t use these meters. They use more advanced equipment.
There are many other kinds of EMF meters used in paranormal investigations. GhostGadgets.com’s has a discussion about the different types and how they work. I attempted to contact the owner of that site with more questions but got no response.
They do capture seemingly anomalous and transient EMFs during paranormal investigations as I observed. An EMF anomaly is an interesting phenomenon regardless of the paranormal association. It is a recording of an environmental variable that shows an unexpected flux. Yet, ghost hunters are rather convinced of their cause. I found this type of statement often: “When you find an unexplainable field, normally between 2 and 7 milligauss, it is associated with spirit activity”. (Source) This statement is problematic. There are too many leaps in logic and no evidence to support that conclusion. The connection between anomalies and spirit activity is assumed. The best we can rationally say is that we found an anomaly. Concluding “I don’t know what is causing this” (often without even a modicum of effort to find out) does not equal “paranormal”. But that is indeed what happens. According to many in paranormal investigation, it’s the default conclusion.
EMF meters “… detect fluctuations in electromagnetic fields and low strength moving EMF fields that have no source,” says Ghosthunting 101. How do you know there is no source? Has every potential source been eliminated? It is improbable that the investigator has been able to do that. There IS a source. You just didn’t locate it.
“It is a common theory that spirits disrupt this field in such a way that you can tell one is present by higher than normal readings with [an EMF] meter.” (Source) I found that “common theory” assumption in several places – stated that it is “generally accepted” by paranormal investigators that spirits emit an ELF (extremely low frequency) field and this measurement is indicative of their presence. (Curiously, the quote above appeared verbatim and unattributed on many ghost group sites which is evidence that these websites readily copy and paste from each other.) Researchers are often far too conclusive in their baseless assertions: “Nine times out of ten, if a mysterious field is constant and stable, it’s artificial; if it fluctuates wildly, it’s paranormal.” (J.P. Warren, How to Hunt Ghosts, p. 145) Oh, really? Citations please! Show your work! Another possible interpretation of that statement is that the concept of paranormal is too broad and vague to be of any meaning whatsoever.
Messy and Vague Data and Language
Not all paranormal investigators get that excited over EMF spikes because they will admit it’s clearly not a consistent observation. The data are all over the place. Paranormal investigator Kenny Biddle conducted experiments with the widely used K2 Meter made popular due to its appearance in the equipment array of television ghost chasers. He found the readings were inconsistent, the device was very sensitive and also easily manipulated with small electrical devices like cell phones, cameras and camera flashes. [The Bent Spoon magazine V1 p 17-22.]
Some have noted that they had a “paranormal” moment yet the EMF device did nothing. That’s actually a data point that is unsupportive of the theory of EMF=ghosts, but they have not recognized the importance of that. But they would admit that no device conclusive detects ghosts.
There are a few studies that are suggestive that haunt phenomena is correlated to local EMF variances. However, others that have not found this correlation. Much more solid work is needed before we can definitively link EMF anomalies to experiences described as “hauntings”. Yet, the link is widely touted by paranormal researchers.
Vagueness is a problem in this field. We have an unreliable reading of questionable accuracy, positing an unknown source or the source is that which we have not yet conclusively determined to exist. We can’t even get an operational definition of a “ghost”! Science is particular about defining terms and using supporting references. Not so with 99% of paranormal “research.” You can’t do anything resembling science is such a state.
