R. D. Mullen reported "Slan" to be "perhaps the most widely read, and perhaps the best of [van Vogt's] novels." He described the situation of the Slan minority in the imagined society as "obviously intended" as analogous to "the position of the Jews in the Third Reich", though in the novel "there actually is a secret world-wide conspiracy, and the Slans actually do control the world in much the same way as is imagined about the Jews by students of The Protocols of Zion." In American science fiction fandom, the slogan "Fans are slans" quickly developed, making the analogy between science fiction fans, perceived as harassed because of their greater intelligence and imaginative capacity, and the slans in the novel, who are persecuted for their superior mental abilities. Although some regard the usage as a sign of fandom's elitism, along with the related term "mundane" for non-fans, others regard it as a natural reaction to the disapproval of science fiction fans by the broader culture. The related term "slan shack" came to be used in fanspeak for a home occupied primarily by fans. The first Slan Shack to bear that name was established in 1943 in Battle Creek, Michigan by Al and Abby Lou Ashley, Walt Liebscher, E. Everett Evans and fan artist Jack Wiedenbeck. Others have included the Bozo Bus Building in Minneapolis, Minnesota and Lytheria in Milwaukee, Wisconsin. The manga and anime series "Toward the Terra" is influenced by "Slan". Both stories feature a hero named Jommy/Jomy, who discovers that he is a member of a race of telepathic mutants who are persecuted by non-telepathic humans. American science fiction author Kevin J. Anderson completed the sequel to "Slan", titled "Slan Hunter", that includes content from an unfinished draft by van Vogt. It was published July 10, 2007, and credited to both Van Vogt and Anderson. Van Vogt's widow Lydia van Vogt previously gave permission to publish her introduction online, which partly deals with the onset of Alzheimer's disease that van Vogt struggled with at the end of his life.
