Eileen Vartan Barker OBE FBA (born 21 April 1938, in Edinburgh, UK) is a professor in sociology, an emeritus member of the London School of Economics (LSE), and a consultant to that institution's Centre for the Study of Human Rights.
Laurence Iannaccone of George Mason University, a specialist in the economics of religion, wrote that The Making of a Moonie was "one of the most comprehensive and influential studies" of the process of conversion to new religious movements.
[11] Barker responded to the financial issues in a 1995 paper, writing that "[w]hat is less well known is that vast amounts of money are at stake in the fostering of brainwashing and mind control thesis in the anti-cult movement secondary constructions", and noting that "deprogrammers" and "exit counselors" charge tens of thousands of dollars for their services and that "expert witnesses" such as Singer "have charged enormous fees for giving testimony about brainwashing in court cases".
[13] In a 2003 collection of essays in honour of Barker, the influential Oxford University-based religious scholar Bryan R. Wilson commented that INFORM was "often in a position from which it can reassure relatives about the character, disposition, policy, provenance and prospects of a given movement.
[15][16] Wilson added that Barker's social science research, in particular her work on the Unification Church, had been instrumental in demonstrating that the brainwashing concept, which for some years had enjoyed popularity in the media, was unable to explain what actually happened in the process of religious conversion, or to explain why so many members of new religious movements actually leave these movements again after a short period.
[16] Australian psychologist Len Oakes and British psychiatry professor Anthony Storr, who have written critically about cults, gurus, new religious movements, and their leaders, have praised Barker's work on the Unification Church's conversion process.
