psychological point of view. It discusses the psychology of decision-making in the episode, noting, "Homer is becoming a full-blown member of the Movementarians not by a rational choice, ... but through the process of escalating behavioral commitments." The Psychology of the Simpsons explains the key recruitment techniques used by the Movementarians, including the charismatic leader, established authority based on a religious entity or alien being (in this case "Blisstonia"), and the method of taking away free choice through acceptance of the Leader's greatness. The book also analyzes the techniques used during the six-hour Movementarian recruitment film. In that scene, those who rise to leave are reminded that they are allowed to leave whenever they wish. They are, however, questioned in front of the group as to specifically why they wish to leave, and these individuals end up staying to finish watching the film. The book describes this technique as "subtle pressure", in contrast to the "razor wire, landmines, angry dogs, crocodiles and evil mystery bubble Marge confronts to escape, while being reminded again that she is certainly free to leave". The Psychology of the Simpsons writes that "the Leader" is seen as an authority figure, because "he has knowledge or abilities that others do not, but want". Instead of traditional mathematics textbooks, the children on the compound learn from Arithmetic the Leader's Way and Science for Leader Lovers. In Pinsky's The Gospel According to the Simpsons, one of the show's writers recounted to the author that the producers of The Simpsons had vetoed a planned episode on Scientology in fear of the Church's "reputation for suing and harassing opponents". Pinsky found it ironic that Matt Groening spoofed Scientology in spite of the fact that the voice of Bart Simpson, Nancy Cartwright, is a Scientologist, having joined in 1991. Pinsky notes that Groening later "took a shot at Scientology" in Futurama with the fictional religion "Church of Robotology". Groening said he received a call from the Church of Scientology concerned about the use of a similar name. Cultural references When Marge attempts to leave the compound, she is chased by the Rover guard "balloon" from the 1967 television program The Prisoner. Neal Hefti and Nelson Riddle's theme music to the 1960s Batman series is used in the episode to indoctrinate Homer. When Mr. Burns introduces his new religion, most of the sequence is a parody of the promotional video of Michael
