Flawed Science Behind Popular Theory of Female Sexuality Exposed
A major evolutionary psychology hypothesis explaining women's same-sex attractions has collapsed under scrutiny, undone by statistical errors and theoretical inconsistencies. The finding signals broader quality-control problems in sex research that could influence healthcare policies and workplace diversity initiatives relying on flawed behavioral science.

**Kritik av evolutionär teori om kvinnlig sexuell attraktion har metodologiska konsekvenser för forskningsmaterial** Uppsala Universitet ifrågasätter "male choice hypothesis," en tidigare använd evolutionär förklaring till samma-könsat attraherad heterosexuella kvinnor. Teorin hävdade att sådan attraktion utvecklades för att reducera risken för utomäktenskapliga barn och ge män ytterligare parningsöpprtungar. Analysen visar att hypotesen vilar på antagna manliga fitnesfördelar som motsäger etablerad sexualselektionsteori. Kritiskt: Forskningsstödet baserades på ett metodologiskt fel där olabelade mittpunkter på Likert-skalor felaktigt behandlades som jakande svar. Vid korrektion av denna felräkning faller författarnas egna data sönder. Studien presenterar alternativa evolutionära modeller med högre förklaringskraft. För regulatörer och forskningsmiljöer blir detta relevant: Systematiska validerings fel i ursprungsmaterial kan påverka framtida litteraturöversikter och säkerhetsbedömningar inom psykofarmakologisk forskning baserad på denna databas.
The male choice hypothesis proposes that same-sex attractions among heterosexual women evolved primarily for male benefit, reducing the risk of extra-pair paternity and providing additional mating opportunities. However, this theory contains significant flaws. This article critically evaluates the male choice hypothesis, showing that it rests on assumptions about male fitness benefits that are inconsistent with established principles of evolutionary psychology and sexual selection and that it further suffers from internal contradictions and conflicts with the empirical evidence. Analysis shows that support for the hypothesis was inflated by a methodological error in which the unlabeled midpoint of their Likert-type scales was repeatedly treated as an affirmative response. Correction of this error in a reanalysis of the published data demonstrates that the authors' own findings fail to support the hypothesis. Taken together, these issues demonstrate that the male choice hypothesis is not supported by either theoretical reasoning or the empirical evidence presented in its favor, and thus is unlikely to constitute a viable evolutionary explanation for same-sex attractions among heterosexual women. Finally, alternative evolutionary hypotheses are presented that provide more plausible explanations for same-sex attractions among heterosexual women.
