Essentialist beliefs about sexuality-related categories

People form essentialist beliefs about social categories as a strategy to organize their world and to make sense of the similarities and differences between different categories. This research examines four dimensions of essentialist thinking (biological basis, immutability, clarity of discreteness and informativeness) across different sexuality-related categories. Specifically, the categories of gays, lesbians, transsexuals, paedophiles, rapists and prostitutes were studied. Results show that essentialist beliefs of the six categories vary across dimensions and that essentialist dimensions function independently. Therefore, we discuss the relative usefulness of taking a global measurement as opposed to analysing the dimensions of essentialism separately.
