A few years ago this question would have been common, however since the rise of programs such as 'Ghost Hunters International', 'TAPS' and most people are aware of the role of a Paranormal Investigator.
Having said that for those of you who may still be unaware we will look at what a paranormal investigator's role is.
Paranormal: is a general term (coined ca. 1915–1920) that designates experiences that lie outside "the range of normal experience or scientific explanation" or that indicates phenomena that are understood to be outside of science's current ability to explain or measure. Notable paranormal beliefs include those that pertain to ghosts, extraterrestrial life, unidentified flying objects, and cryptids.
Investigation: an Investigation conducted to collect data, interview witnesses, compile evidence
Paranormal research is growing in popularity but doesn't yet have the respect of a traditional science, so obtaining training is not as simple as going to your local college.
Whilst there is now available, via some Paranormal organisations, training on how to become an Investigator, most investigators only training is their own personal interest in the paranormal. This is most often hands-on training and provision of necessary equipment. The training teaches individuals how to investigate claims of paranormal activity by using electromagnetic field (EMF) meters, voice-activated digital sound recorders, photograph and video equipment, and infrared heat sensors.
Students are taught to search for logical explanations for the phenomena, and if none can be found, they are trained to gather as much evidence as possible to prove that it is truly an unexplainable event.
Investigators often break down their research into two areas - the Paranormal and Parapsychology (according to the American Institute of Parapsychology, Parapsychology is the formal study of the paranormal).
Whilst the vast majority of mainstream educational institutions, do not offer an actual degree in the field of parapsychology, some institutions do offer parapsychology as a minor, with a major in psychology.
It is also important to note that many Paranormal Investigations Teams incorporate members with certain skills or training which may be useful during investigations.These particular skills may include:
