Electronic Voice PhenomenaVoices of the Dead?James E. Alcock, PhDWhen we talk about communication with the dead, we are usually referring to “mediums” who talk to the dead on our behalf, or who allow the dead to speak to us through them. What if, instead the dead could speak to us directly, without the middle person? If You Survive Death…?Imagine for a moment that you are the dead person, that your body has died, but your mind / personality / soul lives on. You are surprised by this, and you want to tell people, especially your skeptical friends, all about it – you want to communicate with us. What would you do? You have no voice box therefore you cannot speak. You have no arms or legs or any means of moving objects. But you are – as they say – an “energy field.” Could you reach us by interference with devices that rely upon other energy fields, a radio or tape recorder, for example? But if you were able to generate some sounds on a tape recorder, would any one even detect them, or pay attention if they did? It’s often hard to detect weak signals – and you are but a wraith, a spirit, and probably without a lot of energy. However, there is hope for humans, as Ray Hyman points out, because humans are the best pattern detectors in existence. Pattern detection, in this example, would be the ability to discriminate signal from noise. Voices of the Dead?This is exactly what is happening, according to some people. If you listen carefully, they say, you can hear the voices of the dead in tape recordings. What do the voices of the dead sound like? Here are two examples of actual recordings where people claim to hear spoken words, the words of the dead.
Electronic Voice PhenomenaSo – it’s not so easy to hear the voices, is it? These are examples of what are called electronic voice phenomena, or EVP. We are informed by another website that:
Again, the Web informs us that:
The best way to understand the development of EVP it is to go back a little in time. With the rise of Spiritualism beginning with the “mysterious rappings” of the Fox sisters in the nineteenth century, there have been many attempts to “contact the dead,” while claiming to be engaged in scientific study.
This surprising event naturally piqued his interest, and he turned his attention to making recordings of nothing – that is, recordings made in a quite place with no one around. He continued to detect voices on these tapes, and his studies led to the 1964 publication of his book Rosterna fran Rymden (“Voices from space”). He subsequently recognized some of the voices that his tape recorder picked up, including that of his mother, who called him by her pet nickname for him. However, as we say where I grew up, his mother was already “on the wrong side of the grass;” that is, she was deceased. It seemed natural to him to assume that she was communicating from beyond the grave. Thus, he came to the conclusion that all the voices that he had recorded were voices of the dead. In 1967, he published Sprechfunk mit Verstorbenen (“Radio-link with the dead”).
In 1964, Raudive read Jürgenson’s book, Voices from space, and was so impressed by it that he arranged to meet Jürgenson in 1965. He then worked with Jürgenson to make some EVP recordings, but their first efforts bore little fruit, although they believed that they could hear very weak, muddled, voices. However, one night, as he listened to one recording, he clearly heard a number of voices- and when he played the tape over and over, he came to understand all of them – some of which were in German, some in Latvian, some in French. The last voice on the tape – a woman’s voice – said “Va dormir, Margarete” ("Go to sleep, Margaret"). Raudive later wrote (in his book Breakthrough): “These words made a deep impression on me, as Margarete Petrautzki had died recently, and her illness and death had greatly affected me.” Amazed by this, he then started researching such voices on his own, and spent much of the last ten years of his life exploring electronic voice phenomena. With the help of various electronics experts, he recorded over 100,000 audiotapes, most of which were made under what he described as “strict laboratory conditions.” He collaborated at times with Hans Bender, a well-known German parapsychologist. Over 400 people were involved in his research, and all apparently heard the voices. This culminated in the 1971 publication of his book Breakthrough, mentioned above. His impact was such that these phenomena are now often referred to simply as "Raudive voices." Raudive developed several different approaches to recording EVP, and he referred to:
Raudive delineated a number of characteristics of the voices, (as laid out in Breakthrough):
Of course, to the skeptic, these characteristics are what one might expect if indeed the “voices” are simply misinterpretations of random, “white” noise. EVP TodaySerious parapsychologists today show virtually no interest in EVP, and modern reports in the parapsychological literature find no evidence of anything paranormal in such recordings. That does not deter the devoted, of course: it is claimed that there are more than 50,000 sites on the internet devoted to EVP! Again, an example from the Internet: “Briefly, electronic voice phenomenon (EVP) is the process of capturing messages from the spirit world, including our loved ones in Heaven, by using an ordinary tape recorder. Yes, someone in your family or your special friend who has passed on, can record or imprint their voice onto your tape. It is not the scope of our [web] site to fully explain EVP, but please feel free to visit the learning links below for more information. Our site is designed to help you, the beginner, succeed with EVP” And now it is claimed that one does not even need to be quiet while making the recordings – the voices often show up in the background while one is recording a conversation. Consider these examples (from www.paranormalnetwork.com). Examples: There is no end to the efforts people will make to find “voices.” For example, it is claimed that:
As yet another example of the unbridled enthusiasm and creativity associated with finding voices, consider the American Association of Electronic Voice Phenomena. Its website informs us that: “The membership includes people who record paranormal voices, pictures and information from friends and loved ones on the other side through tape recorders, telephones, fax machines, television, computers and video recorders.” And if one surfs the web, sooner or later, one finds sites that offer to sell devices to help you obtain better recordings! Possible ExplanationsWell, if the voices aren’t spirits, what are they?
While you might accept apophenia as an explanation for voices barely discernable from static, as in the earlier examples above, can it account for the “clear voices’ in the later examples (e.g. – recall the word “Pat” from the tape)? First of all, of course, the extraneous voices, if really there, could be the result of intended or unintended background interruptions by real people – the recordings were not made under any sort of controlled conditions. Secondly, as is discussed below, it is fascinating just how easy it is for our brains to come to interpret certain noise patterns as words, once we know what the words are supposed to be. What is going on? Perception is a very complex process, and when our brains try to find patterns, they are guided in part by what we expect to hear. If you are trying to hear your friend while conversing in a noisy room, your brain automatically takes snippets of sound and compares them against possible corresponding words, and guided by context, we can often “hear” more clearly than the sound patterns reaching our ears could account for. Indeed, it is relatively easy to demonstrate in a psychology laboratory that people can readily come to hear “clearly” even very muffled voices, so long as they have a printed version in front of them that tells them what words are being spoken. The brain puts together the visual cue and the auditory input, and we actually “hear” what we are informed is being said, even though without that information, we could discern nothing. Going one step further, and we can demonstrate that people can clearly “hear” voices and words not just in the context of muddled voices, but in a pattern of white noise, a pattern in which there are no voices or words at all. Given that we can routinely demonstrate this effect, it is only parsimonious to suggest that what people hear with EVP is also the product of their own brains, and their expectations, rather than the voices of the dearly departed. We can describe the process, leading from mental set to expectation to perception to amazement to belief in the following general way (see graphic): We are told that tape recordings made with no one around contain mysterious voices. This sets up a mental set that motivates us to try to discern voices. That is, we must presume that there may be something there, or we would not waste our time in listening. If others have told us what the voices seem to say, this expectancy influences our auditory perception, so that our brains match up bits of random noise to the words that we expect to hear. Of course, if we play the same piece of tape over and over, as is explicitly recommended by some of the web sites cited earlier, and if we do everything we can to focus our attention on the "noise" (perhaps by listening through headphones, again as recommended by the web sites), then we not only increase the likelihood of discerning voices if they really are there, but we maximize the opportunity for the perceptual apparatus in our brain to "construct" voices that do not exist, to detect patterns that match up with our expectations. Then, once we “hear” the voices, then it is easy, given the mental set that is usually involved, to attribute them to deceased individuals. This interpretation is likely to produce an impressive emotional reaction, and since we have now heard what we set out to hear (our expectancy is fulfilled) our belief in the reality of the voices of the dead grows, and this may be rewarding in various ways. Such an outcome is likely to heighten the expectation that we will hear more voices the next time we listen to such tapes.
How to disabuse the believerHow can someone who has heard the voices be persuaded to be more critical and to examine more mundane possibilities? A rational, deliberative discussion is rarely helpful because clear evidence or logic is not involved. Believers are reporting an experience that was highly meaningful and perhaps highly emotional to them – not something that is easily challenged by logic. Moreover, there is a self-selection of people predisposed to believe – the voices are compatible with their belief system. Remember – we process information in two different ways through two more or less separate parts of our brain and nervous system. On the one hand, part of our brain works on a very intuitive / emotional / automatic level, and on the other hand, another part of our brain works according to the logic and rationality that we develop over our lifetimes. These two systems often produce contrary results, and this is especially so where paranormal phenomena are involved. The “believer” removes the contradiction by bringing the intellect into line with the intuitive interpretation, that is, by coming to accept the paranormal – in this case, the voices – as reality, and thereby reshaping the intellectual understanding of the world so that belief in such phenomena appears to be rational. Over time, an impregnable belief system develops which is supported by a very substantial base of personal experience (interpreted in such a way as to support the paranormal belief), as well as anecdotal evidence provided by others. It is very difficult to change such deeply held beliefs, especially if they include a significant emotional component. Consider this example: In my work as a clinical psychologist, a father wanted me to “cure” his gay son. I asked the father how easy would it be for me to turn him (the father) into a gay person? “No way !!!,” he said. I told him that it would likely be as difficult to turn his son into a straight person as it would be to make him, the father, turn gay. Fortunately, he saw the point and came to accept his son as he was. My point is this: When we ask how to turn believers into skeptics, let us ask instead: “How easy would it be for me to persuade you that voices on a tape really are spirits of the dead?” Well, that is probably just how easy it would be to persuade devoted believers that their beliefs about the voices are wrong. What the Raudive voices teach us is that intelligent people – for Raudive was no doubt an intelligent man - can come to believe fervently in phenomena which in
all likelihood do not exist. There is a lesson in this for all of us, for we just as surely may be mistaken in some of our own deeply held convictions. This
is why we must rely on science as the avenue to truth rather than personal
experience or other people's anecdotal reports. Science, with its reliance on
data and its insistence on looking for sources of error and for alternative
explanations, provides the best method that humans have produced for protecting
against error and self-delusion. Electronic Voice Phenomena are the products of
hope and expectation; the claims wither away under the light of scientific
scrutiny.
