Why some people think they hear the voices of the dead

A new study looks at why mysterious voices are sometimes taken as spirits and other times as symptoms of mental health issues.

  • Both spiritualist mediums and schizophrenics hear voices.
  • For the former, this constitutes a gift; for the latter, mental illness.
  • A study explores what the two phenomena have in common.

Even different definitions of the word "clairaudience" reflect the way different people respond to the experience.

Merriam-Webster defines it as "hearing something not present to the ear but regarded as having objective reality," suggesting a hallucinatory experience. The Free Dictionary refers to it as the ability to hear things "outside the range of normal perception," suggesting a sort of superpower to hear what's there, but that others can't hear.

Often, what's heard are voices. In some cases, the hearer finds the experience distressing, and a mental health diagnosis, perhaps of schizophrenia, may result. For other people—such as seance mediums—the phenomenon has spiritual significance, and such voices are interpreted as messages from the dead.

Are these two different phenomena, or are they the same thing, understood differently depending on the context in which they occur? A new study in the journal Mental Health, Religion & Culture suggests the latter, and seeks to work out why hearing voices for some is a symptom of mental illness but for others it's a religious/spiritual experience (RSE). The study assumes sincerity on the part of those reporting hearing voices.

The researchers, led by Adam Powell of Durham University's Hearing the Voice project and Department of Theology and Religion, conducted online surveys of 65 clairaudient mediums they found through contact with spiritualist communities. The survey also included 143 people from the general population who responded in the affirmative to the question "Have you ever had an experience you would describe as 'clairaudient?'" posed through an online study recruitment tool.

All participants spoke English and were aged 18-75. Most (84.4 percent) were from the U.K., with the rest mostly from the North Americas, Europe, or Australasia.

Of the spiritualists surveyed, 79 percent said hearing voices was a normal part of their lives at church and at home, while 44.6 percent said that they heard voices every day. Most respondents reported the voices as being inside their heads, though 31.7 percent said they came from outside their bodies.

Not surprisingly, more spiritualists reported believing in the paranormal than did the general population participants. They also cared less about what others thought of them.

Both groups were prone to visual hallucinations as well.

Youth and absorption

Spiritualist clairaudients reported their first experiences with other voices early in life. Of these participants, 18 percent said they had heard voices for as long as they remembered. The average age, however, for first hearing voices was 21.7 years. Schizophrenia typically presents when a person is somewhat older than this, in the late 20s.

Significantly, 71 percent said their experience with voices pre-dated their awareness of spiritualism. Rather than religion prompting the hearing of voices, it seems that it's more the other way around — voices led them to religion.

Says Powell, "Our findings say a lot about 'learning and yearning.' For our participants, the tenets of spiritualism seem to make sense of both extraordinary childhood experiences as well as the frequent auditory phenomena they experience as practicing mediums."

Still, the voices came first he says, so "all of those experiences may result more from having certain tendencies or early abilities than from simply believing in the possibility of contacting the dead if one tries hard enough."

The more likely factor is spiritualist clairaudients' relationship with absorption. Responses to questions based on the 34-point Tellegen Absorption Scale revealed that these people tended toward absorptive personality characteristics. These are described by the study's authors as "being readily captured by entrancing stimuli, reporting vivid mental imagery, becoming immersed in one's own thoughts."

Some, though not all, voice-hearing individuals from the general population were found to exhibit high levels of absorption — those that did were more likely to believe in the paranormal than others.

Implications

The study's finding regarding the relative young ages at which spiritualist clairaudients begin hearing voices suggests that these individuals' more welcoming attitude toward the phenomenon may have to do with malleability of youth — a belief in the fantastical is part of being young.

"Spiritualists tend to report unusual auditory experiences which are positive, start early in life and which they are often then able to control," says co-author Peter Moseley of Northumbria University. "Understanding how these develop is important because it could help us understand more about distressing or non-controllable experiences of hearing voices too."

The authors of the study do note, however, that their findings leave two big unanswered questions: Does a tendency toward absorption reveal "a predisposition to having RSEs or a belief in the plausibility of having RSEs?"

The other obvious big question? It's beyond the scope of this survey, but are those really the voices of the dead?


A landslide is imminent and so is its tsunami

An open letter predicts that a massive wall of rock is about to plunge into Barry Arm Fjord in Alaska.

  • A remote area visited by tourists and cruises, and home to fishing villages, is about to be visited by a devastating tsunami.
  • A wall of rock exposed by a receding glacier is about crash into the waters below.
  • Glaciers hold such areas together — and when they're gone, bad stuff can be left behind.

The Barry Glacier gives its name to Alaska's Barry Arm Fjord, and a new open letter forecasts trouble ahead.

Thanks to global warming, the glacier has been retreating, so far removing two-thirds of its support for a steep mile-long slope, or scarp, containing perhaps 500 million cubic meters of material. (Think the Hoover Dam times several hundred.) The slope has been moving slowly since 1957, but scientists say it's become an avalanche waiting to happen, maybe within the next year, and likely within 20. When it does come crashing down into the fjord, it could set in motion a frightening tsunami overwhelming the fjord's normally peaceful waters .

"It could happen anytime, but the risk just goes way up as this glacier recedes," says hydrologist Anna Liljedahl of Woods Hole, one of the signatories to the letter.

The Barry Arm Fjord

The Barry Arm Fjord is a stretch of water between the Harriman Fjord and the Port Wills Fjord, located at the northwest corner of the well-known Prince William Sound. It's a beautiful area, home to a few hundred people supporting the local fishing industry, and it's also a popular destination for tourists — its Black Sand Beach is one of Alaska's most scenic — and cruise ships.

There have been at least two similar events in the state's recent history, though not on such a massive scale. On July 9, 1958, an earthquake nearby caused 40 million cubic yards of rock to suddenly slide 2,000 feet down into Lituya Bay, producing a tsunami whose peak waves reportedly reached 1,720 feet in height. By the time the wall of water reached the mouth of the bay, it was still 75 feet high. At Taan Fjord in 2015, a landslide caused a tsunami that crested at 600 feet. Both of these events thankfully occurred in sparsely populated areas, so few fatalities occurred.

The Barry Arm event will be larger than either of these by far.

"This is an enormous slope — the mass that could fail weighs over a billion tonnes," said geologist Dave Petley, speaking to Earther. "The internal structure of that rock mass, which will determine whether it collapses, is very complex. At the moment we don't know enough about it to be able to forecast its future behavior."

Outside of Alaska, on the west coast of Greenland, a landslide-produced tsunami towered 300 feet high, obliterating a fishing village in its path.

What the letter predicts for Barry Arm Fjord

"The effects would be especially severe near where the landslide enters the water at the head of Barry Arm. Additionally, areas of shallow water, or low-lying land near the shore, would be in danger even further from the source. A minor failure may not produce significant impacts beyond the inner parts of the fiord, while a complete failure could be destructive throughout Barry Arm, Harriman Fiord, and parts of Port Wells. Our initial results show complex impacts further from the landslide than Barry Arm, with over 30 foot waves in some distant bays, including Whittier."

The discovery of the impeding landslide began with an observation by the sister of geologist Hig Higman of Ground Truth, an organization in Seldovia, Alaska. Artist Valisa Higman was vacationing in the area and sent her brother some photos of worrying fractures she noticed in the slope, taken while she was on a boat cruising the fjord.

Higman confirmed his sister's hunch via available satellite imagery and, digging deeper, found that between 2009 and 2015 the slope had moved 600 feet downhill, leaving a prominent scar.

Ohio State's Chunli Dai unearthed a connection between the movement and the receding of the Barry Glacier. Comparison of the Barry Arm slope with other similar areas, combined with computer modeling of the possible resulting tsunamis, led to the publication of the group's letter.

While the full group of signatories from 14 organizations and institutions has only been working on the situation for a month, the implications were immediately clear. The signers include experts from Ohio State University, the University of Southern California, and the Anchorage and Fairbanks campuses of the University of Alaska.

Once informed of the open letter's contents, the Alaska's Department of Natural Resources immediately released a warning that "an increasingly likely landslide could generate a wave with devastating effects on fishermen and recreationalists."

How do you prepare for something like this?

The obvious question is what can be done to prepare for the landslide and tsunami? For one thing, there's more to understand about the upcoming event, and the researchers lay out their plan in the letter:

"To inform and refine hazard mitigation efforts, we would like to pursue several lines of investigation: Detect changes in the slope that might forewarn of a landslide, better understand what could trigger a landslide, and refine tsunami model projections. By mapping the landslide and nearby terrain, both above and below sea level, we can more accurately determine the basic physical dimensions of the landslide. This can be paired with GPS and seismic measurements made over time to see how the slope responds to changes in the glacier and to events like rainstorms and earthquakes. Field and satellite data can support near-real time hazard monitoring, while computer models of landslide and tsunami scenarios can help identify specific places that are most at risk."

In the letter, the authors reached out to those living in and visiting the area, asking, "What specific questions are most important to you?" and "What could be done to reduce the danger to people who want to visit or work in Barry Arm?" They also invited locals to let them know about any changes, including even small rock-falls and landslides.
