One ghost-hunting group reports that the number of people taking their tours has tripled, jumping from about 600 in 2006 to 1,800 in 2008. Another says its membership has doubled. Others point to increased traffic on their websites and message boards as an indication that ghost hunting is becoming more accepted. Participants say that ghost hunting allows them to enjoy the friendship of like-minded people and actively pursue their interest in the paranormal. James Willis, founder of The Ghosts of Ohio group says that his membership has grown to 30 members since it was founded in 1999 and includes both true believers and total skeptics.

 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". In his article for Skeptical Inquirer Magazine 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."

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.
