It is depressing how completely the NRM sociologists have been captured by the NRMs. This volume, especially the pieces by the most distinguished scholars, reads like a PR write-up. The most prominent scholar is J. Gordon Melton, who wrote a 2000 book about the church. His lengthy overview of the Church's history in this volume ("The Birth of a Religion"), exemplifies the book's failures, omitting or soft-pedaling aspects of the church's history which might cast it in a poor light: 1. the high payments the Church extracts from members; 2. its policy of harrassing critics by litigation; 3. the existence of dissident groups within the Dianetics / Scientology movement.
First, Melton's reference to the Church's payment policy for auditing are brief and offhand and don't contextualize it comparatively, i.e. they do not note that few if any other churches charge so much money for their essential religious rituals. The Church of Latter-Day Saints, for instance, expects a significant financial commitment from members, but they can still participate in all aspects of the Church (including, if I'm not mistaken, Temple rituals) while declining to contribute money.
Second, neither Melton's chapter nor those of others in the book refer to the Church of Scientology's aggressive and explicit policy of suing critics (stemming from L. Ron Hubbard's "Fair Game" policy). The book includes a well-researched article by James Richardson on "Scientology in Court," but it ignores this kind of litigation to concentrate exclusively on the Church's struggles for religion status in various countries. And Anson Shupe's chapter on "The Church of Scientology versus the Cult Awareness Network" seems to take clear sides in favor of the Church.
Third, Melton does not say anything about the "Free Zone" body of Scientology organizations outside the official Church; these would seem to be a legitimate part of the "Birth of a Religion." No overview of Mormonism, for instance, would ignore the existence of independent Mormon churches outside the Church of Jesus Christ of Latter-Day Saints.
Finally, the biographical sketch of L. Ron Hubbard which makes up a large part of the chapter is unrelentingly eulogistic. It is full of charming anecdotes ("Befriended by the local Blackfoot Indians, he was made a blood brother at the age of six") and unconditional rebuttals of criticism. Melton ends the chapter with a moving description of the desk and writing materials kept in each Scientology center "as if one day [Hubbard] might walk into the building and need a place to continue his work." Honestly, the whole chapter would be an effective pamphlet for distribution at Scientology centers.
I do not for an instant question Dr. Melton's or other NRM scholars' good faith or scholarly expertise, but I suspect that the nature of the research, beginning from an explicit (and appropriate, for scholarly research) posture of non-judgment, can slide towards apologetics -- especially since the Church makes an effort to win scholars' good will, as it does with celebrities. I wish that Melton and other researchers would interrogate the Church's point of view as skeptically as those of the Church's critics. Also, while I know nothing about the financial support of Dr. Melton's research, I hope that all NRM researchers will be scrupulous about declaring any financial support for their research from the Church (including paying travel costs and subsidizing conferences). The situation, I suspect, is similar to that of medical researchers who overtime become more or more compromised by the support for their research provided by pharmaceutical companies.
