“Dennis Combs, an assistant professor of psychology at the University of Texas at Tyler, has been studying paranoia for about a decade. When he first started conducting paranoia studies, mostly in college students, he found that about 5 percent of them had paranoid thoughts. In recent years, that has tripled to about 15 percent, he said.
In a small experiment in London, Freeman concluded that a quarter of people riding the subway in the capital probably have regular thoughts that qualify as paranoia. In the study, 200 randomly selected people (those with a history of mental problems were excluded) took a virtual reality train ride. They recorded their reactions to computerized passengers programmed to be neutral.
More than 40 percent of study participants had at least some paranoid thoughts. Some felt intimidated by the computer passengers, claiming they were aggressive, had made obscene gestures, or tried to start a fight.
…”We are now starting to discover that madness is human and that we need to look at normal people to understand it,” said Dr. Jim van Os, a professor of psychiatry at Maastricht University in the Netherlands.”
