A recent study proves that at least some people possess an independent sixth sensethat allows them to detect whether someone is watching them. In the study, subjects were seated one at a time in the center of a room facing away from a large window. On average, subjects decided correctly 60 percent of the time whether or not they were being watched through the window.
Most of the time, subjects said they were being watched, if true, most supports the conclusion drawn from the study mentioned above.
