The paranormal, specifically the UFO phenomenon, is a subject that scientists must acknowledge as being of particular interest to their fields. This is mainly a question of defense: A lot of UFO reports are hoaxes, misidentifications, or some other easily explainable problem. The public, however, has a considerable interest in the subject, and if scientists do not debunk and demystify the bumper crop of hogwash related to this subject, they may find the line between science and fantasy irreparably blurred. Even these seemingly useless hoaxes, tricks, and mass hysterias can yield valuable data for scientists in the fields of psychology and sociology.Some things, such as "lights in the sky" may also have a value to physicists, meteorologists, and other 'hard' scientists. One thing associated with UFOs that will never, ever, give up any hard scientific data is the phenomena of the so-called "Men In Black."Basically, it goes like this: If you see a UFO and talk about it, eventually some men wearing dark suits, perhaps acting oddly, will call on you and threaten that you'd better stay quiet. Some believe these men to be government agents, some to be harmless cranks, and some to be alien visitors or travelers from other dimensions. Other than incredible stories, there is no hard evidence to show that these men are anything other than regular flesh-and-blood human beings. I'm sure that disappoints all the computer scientists itching to get their hands on a remote-controlled robot built from alien technology, but it should delight scientists working on the mind: Stories of Men In Black can surely point you to some interesting case studies in mental disorders.
