In "", the authors cite "escaping from a cult commune in 'The Joy of Sect'" as evidence of "Aristotle's virtuous personality traits in Marge." As the title suggests, the book "The Psychology of the Simpsons: D'oh!" examines "The Joy of Sect" from a 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".
