Joe,
actually there's nothing much to add to what Andreas has written. The respective American acronym is CSICOP (Committee for the Scientific Investigation of Claims of the Paranormal) sometimes misnamed Psi-Cop by their opponents. Reading sceptical literature on such claims is my second way of spending the free time if I do not visit MUDCAT (now, if that was an acronym, what would it stand for? Musik Und Dichtung, Charakteristischerweise aus Alten Texten)
