"The least likely explanation for any given reading is it is a ghost," maintains Nickell. Orbs of light that show up on photos, he says, are often particles of dust or moisture. " Voices" picked up by tape recorders can be radio signals or noise from the recorder, EMF detectors can be set off by faulty wiring, microwave towers, iron, recording equipment, or cell phones, and heat sensors can pick up reflections off of mirrors or other metal surfaces. Nickell has also criticized the practice of searching only in the dark, saying that since some ghosts are described as "shadows or dark entities," he conducts searches in lighted rather than darkened conditions.

make many methodological mistakes. According to Radford, " ter watching episodes of '' Ghost Hunters'' and other similar programs, it quickly becomes clear to anyone with a background in science that the methods used are both illogical and unscientific". Anyone can be a ghost investigator, "failing to consider alternative explanations for anomalous… phenomena", considering emotions and feelings as "evidence of ghostly encounters". "Improper and unscientific investigation methods" for example "using unproven tools and equipment", "sampling errors", "ineffectively using recording devices" and "focusing on the history of the location... and not the phenomena".

'' Radford concludes that ghost hunters should care about doing a truly scientific investigation: "I believe that if ghosts exist, they are important and deserve to be taken seriously. Most of the efforts to investigate ghosts so far have been badly flawed and unscientific – and, not surprisingly, fruitless." Although some ghost hunters believe orbs are of supernatural origin, skeptic Brian Dunning says that they are usually particles of dust that are reflected by light when a picture is taken, sometimes it may be bugs or water droplets. He contends that "there are no plausible hypotheses that describe the mechanism by which a person who dies will become a hovering ball of light that appears on film but is invisible to the eye." He does not believe there is any science behind these beliefs; if there were then there would be some kind of discussion of who, what and why this can happen. In his investigations he can not find any "plausible hypothesis" that orbs are anything paranormal. Science writer Sharon Hill reviewed over 1,000 "amateur research and investigation groups" (ARIGs), writing that "879 identified with the category of 'ghosts'". Hill reports that many groups used the terms "science" or "scientific" when describing themselves; however they overwhelmingly display neither understanding of nor adherence to scientific norms. Hill writes: Hill sees the supernatural bias of such groups as an indication of how "far removed ARIG participants really are from the established scientific community". In Hill's 2017 book ''Scientifical Americans'' reviewed by historian Brian Regal for ''

Regal wonders why believers think that "untutored amateurs know more (and are more trustworthy) than professional scholars".

For example, the theoretical questions such as "what is a ghost?" and "does one's religion in life determine if they can become a ghost in death?" Hill gives a

As of the 2010 United States Census, the borough's population was 540,EVPs while there. According to Biddle, many of the ghost hunters claimed that the EVPs they obtained "were not just random responses; they were direct, intelligent responses to specific questions". To challenge these claims, Biddle's group conducted a controlled experiment: the group recorded audio while asking any spirits in the Mansion to help them in locating a small foam toy hidden somewhere on the premises by a third party. They asked direct questions, but no responses were detected during review of the audio. Biddle subsequently reset the experiment and has offered a prize to ghost hunters for proof of their claim that they can obtain direct answers from spirits via EVP.
