Scholars are familiar with the 7 points of the Kinsey Scale (KS)—whole integers, 0 to 6—but are unaware of several facts about the KS. First, most ratings were not self-ratings, but assigned by interviewers after the interview. Second, there was an X category given to individuals who did not respond sexually to either heterosexual or homosexual stimuli. Third, part of the subsample with extensive homosexual experience was asked a specific self-rating question. Sometimes this self-rating resulted from a brief discussion between interviewer and interviewee; occasionally the self-rating was overriden by the interviewer. Finally, even though the choices presented to an interviewee were the familiar 0 to 6, intermediate values—such as “1–2” or “4–5”—were permitted. Such intermediate self-ratings often occurred with frequencies exceeding those for the neighboring round numbers. Thus, the detailed psychometric properties of the original KS remain to be established.
