         10 Scientific Explanations

              for Famous Ghostly

                     Phenomena




                     by Nolan Moore


        According to a 2005 Gallup poll, 37 percent of
        Americans believe in haunted houses, and
        according to a 2013 HuffPost/YouGov poll, 45
        percent believe in ghosts. These are surprising
        numbers, but the next time you hear a spooky
        sound, don't call the Ghostbusters—get a
        scientist instead. Behind every shadow,
        poltergeist, and disembodied voice, there's a
        perfectly rational explanation.
