classical concept of sexual orientation with its stereotypical categories of heterosexuality, bisexuality, and homosexuality first appeared in Western thought in the mid-19th century and has since been widely appropriated as a basis for self-identification. The concept of sexual orientation has been studied intensively by various branches of science, which have proven it to be false in its classical, essentialist form. In a last-ditch “rescue attempt”, sexology is currently attempting to extend this concept beyond gender dualism. The concept of sexual orientation is associated with a variety of seemingly mythical, pseudo-scientific assumptions that have been lifted from scientific work into public discourse by media sensationalism. In this research paper, we examine the prevalence of terminology associated with the three sexual orientation stereotypes of heterosexuality, bisexuality, and homosexuality within sexological discourse. ^We conduct a word frequency analysis of scientific articles published between 2005 and 2014 in the “Zeitschrift für Sexualforschung”. Over this publication period, 63.4% of all articles (total number of articles: N=238) included instances of this stereotypical terminology (term matches: N=2926), and 21.6% of all articles mentioned these terms 10 times. There was a clear preference for terminology associated with homosexuality, which scored 66% compared to 18% for heterosexuality and 12% for bisexuality, whereas the superordinate terms (sexual orientation and sexual identity) only represented 4% of the search query results. Significant correlation was found between some of these search terms and topical keywords chosen from the data pool. For example, the term “schwul” (“gay”) exhibited very significant correlation with the keyword “AIDS”, which encourages word-associative connections between these two terms, aggravating infection-related myths. ^Similar relationships were found for keywords relating to reproduction, exacerbating reproduction-related myths by forcing word-associative correlations and links between concepts. Despite the scientific research invalidating the concept of sexual orientation, it remains surprisingly prevalent throughout science.
