From an interesting article on the CSICOP web site:
Scientists have long lamented the public’s persistent belief in the paranormal. In this area, recent Gallup polling shows both good news and bad news. Every few years since 1990 the survey organization has asked Americans whether they believe, don’t believe, or are not sure about a range of paranormal phenomena. The good news is that compared to 2001, fewer Americans say they believe in extra-sensory perception, fewer Americans say they believe in the ability to communicate with the dead, and fewer Americans say they believe that extra-terrestrials have visited the Earth. …
The bad news is that public belief in other forms of paranormal phenomena shows little or no significant change. Specifically, there remains relatively strong belief in psychic/spiritual healing (55% say they believe, 17% say they are unsure, and only 26% say they don’t believe), in devil possession (42%, 13%, and 44% across response categories), and in haunted houses (37%, 16%, and 46% respectively)…
