Paranormal investigation — commonly referred to as ghost hunting in its popular, amateur form — is the practice of visiting locations reported to be haunted or otherwise paranormally active, using a combination of interviews, historical research, and specialised equipment in an attempt to document and, where possible, explain the reported phenomena.[1] The practice spans a wide range of rigour, from academically-grounded parapsychological research to informal amateur groups, and is widely classified as a pseudoscience by mainstream educators and academics on the grounds that it does not follow standard scientific method.[1]
History
Organised paranormal investigation traces its origins to 19th-century psychical research, most notably the founding of the Society for Psychical Research in 1882, which applied comparatively systematic methods — witness interviews, case documentation, controlled sittings with mediums — to claims of hauntings, telepathy and mediumship.[1] British investigator Harry Price, one of the most prominent early ghost hunters, published his memoir Confessions of a Ghost-Hunter in 1936, helping establish "ghost hunter" as a recognisable public role distinct from academic parapsychology.[1]
The modern, equipment-heavy amateur form of paranormal investigation expanded dramatically from the early-to-mid 2000s, driven substantially by television series such as Most Haunted in the UK and Ghost Hunters in the United States, combined with the increasing affordability of the specialised electronic equipment the genre popularised.[1] The Atlantic Paranormal Society (TAPS), the group featured on Ghost Hunters, reported its membership roughly doubling during the late 2000s, a growth it attributed directly to the show's popularity.[1] Small businesses supplying ghost-hunting equipment and paranormal investigation services grew substantially over the same period.[1]
Standard equipment and methods
EMF meters
Electromagnetic field (EMF) meters, which detect fluctuations in electromagnetic fields, are among the most widely used tools in modern ghost hunting, based on the belief — not accepted by mainstream physics — that a spirit's presence can disturb the local electromagnetic field.[2] The specific device most associated with the practice, the K-II (or "K2") meter, was not originally designed for paranormal use at all — it was created for electricians to locate wiring and appliance-generated fields — before ghost hunters adopted it for its sensitivity and simple LED-based readout, and it became widely recognisable following its regular appearances on Ghost Hunters from 2007 onward.[3][4]
EVP recorders
Electronic Voice Phenomena (EVP) — apparent voices or sounds captured on audio recordings that were not audible to investigators at the time of recording — have a documented history stretching back to the 1950s, when Swedish painter and film producer Friedrich Jürgenson reported capturing what he believed to be spirit voices on tape.[5] Latvian psychologist and parapsychologist Konstantīns Raudive conducted extensive further research and recording throughout the 1960s and 1970s, producing what remains some of the most widely studied EVP material in the field.[6] Modern investigators typically conduct structured "EVP sessions," asking questions aloud and reviewing the resulting audio afterward for unexplained responses.
Other equipment and techniques
Infrared and thermal-imaging cameras are used to detect temperature changes or figures not visible to the naked eye; digital voice recorders, static and handheld video cameras, and "trigger objects" (items placed to detect movement) round out a typical investigation kit.[1] Investigations are typically preceded by baseline environmental readings — establishing normal temperature and EMF levels for a location before any claimed activity is assessed against them — alongside witness interviews and historical research into the site itself, a structured approach followed to varying degrees of rigour by groups including Spirit Searchers, Paranormal Lincs, and the Grimsby Ghostbusters.[6]
Scientific and sceptical reception
No scientific study has confirmed the existence of ghosts, and paranormal investigation is considered a pseudoscience by the large majority of educators, academics and science writers.[1] Sceptics highlight that EMF readings in particular are prone to mundane false positives — the Amityville house, for instance, was initially reported to show unusually high EMF activity, later attributed to poor wiring and malfunctioning electrical fixtures rather than any paranormal cause.[2] Joe Nickell and other sceptical investigators have separately argued that most investigation teams "want it to look like they are doing science" without adopting the basic scientific practice of running control conditions — comparing a "haunted" location against an ordinary one under matched circumstances — a criticism examined in more depth on the Vault's Poltergeist page.
Investigators sympathetic to the practice generally acknowledge these limitations to varying degrees, typically emphasising that no single piece of equipment is treated as conclusive evidence on its own, and that credible findings require corroboration across multiple, independently repeatable readings.[2]
Relevance to the Vault
Paranormal investigation as a practice underlies a large proportion of the Vault's own content: the methodology, equipment and general approach described here is common, in varying degrees of rigour, across groups already documented including Spirit Searchers, Paranormal Lincs, the Grimsby Ghostbusters, and the New England Society for Psychic Research. It stands in useful contrast to more formally scientific approaches to testing paranormal claims, such as the James Randi Educational Foundation's One Million Dollar Paranormal Challenge, which required pre-agreed, controlled testing protocols rather than open-ended on-site investigation.
