Research compilations for ambient magnetic conditions and psi functioning provided by S. James P. Spottiswoode suggest a negative correlation: Retrospective analyses of putative spontaneous psi, or anomalous cognition (AC), events have shown a tendency for these to be reported on days of relatively low geomagnetic disturbance. jsasoc.com/library.html
Haunting events and EVP are believed to be a psi function, but nevertheless, there has been no research reported that supports the view that EVP is influenced by the magnetic environment The following research report details an effort to determine if there is a detectible correlation.
Those who believe EVP to be real think that the voices of the dead are being recorded while those who do not believe in the paranormal nature of these phenomena claim that they are nothing more than stray radio waves or auditory pareidolia or apophenia. It is a proven fact that the human mind can create meaning out of insignificant sound and random noise. Those who support the paranormal nature of this phenomena claim that the voices are interactive and can be identified as someone who has died. The question then, is how do the deceased manifest their voices on the recording equipment?
Some EVP researchers, ghost hunters and paranormal investigators believe that entities use physical sound energy and re-modulate it to form words. In addition, there is anecdotal evidence that:
The ghost hunting community overall believes that times of increased solar activity are ideal for ghost hunting. It is thought that, with enough energy in the air from charged ions and an energized electromagnetic field, manifestations, including EVP, are more plentiful and clear (2, 9, 10). This belief is due to investigator’s personal experiences and the extrapolation and interpretation of the published scientific literature.
There are published studies in peer reviewed academic journals and books that describe a correlation between paranormal activity and geomagnetic fields (3, 8). Some studies have shown there is an increase in poltergeist (Recurrent Spontaneous Psychokinesis or RSPK) events when there is an increase in the geomagnetic field (3, 6), while others found a correlation between an increase in the geomagnetic field and an increase in haunt phenomena, postmortem apparitions, and sensed presences (5, 8). The interpretation of these correlations is open to debate. Some think that the increase in geomagnetic activity either triggers and/or fuels the activity (especially in the RSPK studies) while others feel that the changes in geomagnetic fields and complex electromagnetic fields can induce hallucinations.
There is little or no formal analysis that increased geomagnetic activity leads to an increase in the frequency and clarity of EVP. This study is an attempt to determine if there is a correlation between geomagnetic activity and the quantity of EVP.
EVP: EVP from 2001 to 2005 were obtained from the Southern Wisconsin Paranormal Research Group case files, the South Jersey Ghost Research Group and the personal files of Cindy Heinen. The number of EVP recorded on each day were tabulated in an Excel spreadsheet. Both days with EVP recorded and days where recording for EVP was attempted but there were no EVP recorded were included.
Geomagnetic Activity: Magnetic field variation can come from currents caused by solar radiation changes. Solar winds can interact with the magnetosphere. The magnetosphere and ionosphere can cause magnetic field changes by themselves. Magnetic activity indices provided by National Oceanic and Atmospheric Association (NOAA) are used to describe the variation in the geomagnetic field (13).
The a-index is a 3-hourly “equivalent amplitude” index of the local geomagnetic activity; “a” is related to the 3-hourly K-index.
The A-index is the daily index of geomagnetic activity derived as the average of the eight 3-hourly a-indices.
A-index values (24-hrs) of the following determine the geomagnetic conditions:
Statistical Analysis: To determine if there was a correlation between the number of EVP recorded and the estimated Ap-index, the number of EVP vs. the estimated Ap-index was plotted and a nonparametric correlation Spearman r analysis was performed using GraphPad InStat version 3.05 for Windows 95/NT, GraphPad Software, San Diego California USA, www.graphpad.com
To determine if there was a difference in the mean estimated Ap-index for when EVP were recorded vs. when no EVP were recorded, a nonparametric Mann-Whitney t-test was performed using GraphPad InStat.
Finally, to determine if a certain level of enhanced geomagnetic activity leads to more EVP, the mean number of EVP was compared for the following:
The analysis for each was done with a nonparametric Mann-Whitney t-test using GraphPad InStat.
Two hundred and ten data points were collected and spanned the time period of January 6th, 2001 to August 27th, 2005. There were 101 days with EVP and 109 days without EVP. The number of data points for each estimated Ap-index range/geomagnetic condition were: 0 to 7/“Quiet” = 61; 8 to 15/”Unsettled” = 82; 16 to 24/”Active” = 39; 25 to 35/”Minor Storm” = 18; 36+/”Major Storm” = 10.
Figure one shows the number of EVP plotted against the estimated Ap-index. Spearman r = 0.02882 (95% CI –0.110 to 0.1675; P=0.6779; not significant).
r = 0.02882, 95% CI –0.110 to 0.1675; P=0.6779; not significant
Table 1 shows the results of the statistical analysis for the various comparisons.
There is a general belief among the hauntings investigation community that an increase in the geomagnetic field enables paranormal manifestations to be more plentiful and clear. It has been speculated that this extends to EVP as well (2, 9, 10). These beliefs are based on investigator's personal experiences and conclusions they draw from reading the published scientific literature. There is little if any formal analysis indicating that increases in geomagnetic activity leads to an increase in the number of EVP. This study explored the possibility that increases in the geomagnetic field (as measured with the estimated Ap-index) would lead to an increase in the quantity of EVP.
There was no significant correlation found between the estimated Ap-index and the number of EVP. In addition, there was no significant difference in the mean number of EVP recorded during “Quiet” geomagnetic conditions vs. the mean number of EVP recorded during “Unsettled”, “Active”, “Minor Storm”, or “Major Storm” geomagnetic conditions.
This study has several limitations:
Despite the limitations, this study has shown that there doesn’t appear to be any correlation between geomagnetic conditions and the number of EVP recorded. However, more studies will need to be done looking at various other factors to see if any other environmental conditions can effect and quantity and quality of EVP.
