In June 2008, Ghost Hunters was awarded The Truly Terrible Television (TTTV) Award by Independent Investigations Group for peddling pseudoscience and superstition to its audience. During the seven-hour-long, live Halloween show on October 31, 2008, at least two events took place that critics have scrutinized: One occurs when lead investigator Grant Wilson has his jacket collar pulled down by an unseen force three times; all the while one of his hands remained at his side, which led detractors to claim he was pulling a hidden string. This happens again at one point where Hawes touches Wilson's back and his collar moves down again. Another occurs when a supposed disembodied voice tells the hunters, "You're not supposed to be here." Critics have claimed the voice sounded like it was piped in from an external audio source. In regard to the scrutiny, Wilson and Hawes defended themselves, stating that everything in the show is real. In a 2013 interview on The Reveal, Wilson stated that their television contracts forbade them from faking evidence on the show. According to investigator Benjamin Radford, most ghost hunting groups including TAPS make many methodological mistakes. "After 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." In an article for Skeptical Inquirer, 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." In a New York Times article about Ghost Hunters and TAPS, Radford contended that "the group and others like it lack scientific rigor and mislead people into thinking that their homes are haunted." The show's editing has been questioned, such as activity that is not captured on tape and findings that are unsupported by evidence in the show specifically. Tools are used in ways that are not proven effective, or in ways in which
