Introversion

From Fancyclopedia 2, ca. 1959

Most fans are introverted to a greater or less degree, it's generally held. The characteristics of introspection, imagination, greater interest in oneself than other people, and in ideas than people, are well marked in our writings and face-to-face personalities. (Extroverts are characterized by "practicality", salesmanship, inability to be alone, and concern about tangible honors and other people's opinion of them.) But the intensity appears less marked today than before the end of World War II, and some of our members even go the length of being professional salesmen. The only actual figures were obtained during the early 40s by the Poll Cat, which circulated a psychological questionnaire answers to which indicated that 92% of fans were introverts, 8% ambiverts, and none extroverts.
