Your contact may say he or she is from Scientology, or they may be from a Dianetics Center. The two are equivalent, but sometimes the word Scientology is introduced carefully, so as not to alarm the new person. There are dozens, perhaps hundreds of groups within Scientology. Some acknowledge that the Church of Scientology International is the central organization. Others are more secretive, saying only that they are based on the teachings of L. Ron Hubbard. Your contact should be able to name at least some from the following lists.
Openly Scientology-related groups: Church of Scientology International, Religious Technology Center, Church of Spiritual Technology, World Institute of Scientology Enterprises, Association for Better Living and Education, Citizen's Commission on Human Rights, Association of Scientologists International, Golden Era Studios, Bridge Publications, Author Services, Inc.
Groups which may hide their connection to Scientology: World Literacy Crusade, Narconon, Criminon, Drug Free Marshals, Set a Good Example Campaign, Association of IRS Whistleblowers, Citizens for an Alternative Tax System.
Why are there so many different names for Scientology, and why do some groups hide their affiliation to Scientology? Does it seem that Scientology hides its name behind front groups to be more acceptable to the public? If you are approached by a front group of Scientology, does it seem to be really charity-oriented, or do they seem more recruitment-oriented?
