 Various groups, including the Aumism movement and the Belgian Raelian Movement, have opposed Abgrall.Dick Anthony and Thomas Robbins have written that in their view, Abgrall's theories of brainwashing are pseudoscientific, and so unsuitable for use as a basis for legal judgments in cases involving cult membership.They qualify Abgrall as the "leading psychiatric consultant to government agencies and legislative bodies concerned with controlling and suppressing non-traditional religions", noting that Abgrall's brainwashing theory has served as the primary psychiatric rationale for anti-cult laws, governmental rulings, and legal cases brought against alleged cults in Europe.
