The episode is used by the Farmington Trust (UK) for Christian religious education, to teach children about skepticism. The episode is used as a tool, to involve the students in a debate about religion and science, as well as to discuss Lisa's own skepticism, and her respect towards others. A group of "The Simpsons" enthusiasts at Calvin College have also analyzed the religious and philosophical aspects of the episode, including the issue of faith versus science. The episode has been compared with Gabriel García Márquez's short story "A Very Old Man with Enormous Wings" and utilized as a teaching tool in a Saugerties, New York grade school class. In an exam on the subject, students were asked to use details from both "A Very Old Man with Enormous Wings" and "Lisa the Skeptic", in order to analyze the quotation "Appearances can be deceiving".
