What is “The Kinsey Scale?”

The Heterosexual-Homosexual Rating Scale, sometimes referred to as the “Kinsey Scale,” was developed by Alfred Kinsey and his colleagues Wardell Pomeroy and Clyde Martin in 1948, in order to account for research findings that showed people did not fit into neat and exclusive heterosexual or homosexual categories.

Interviewing people about their sexual histories, the Kinsey team found that, for many people, sexual behavior, thoughts and feelings towards the same or opposite sex was not always consistent across time. Though the majority of men and women reported being exclusively heterosexual, and a percentage reported exclusively homosexual behavior and attractions, many individuals disclosed behaviors or thoughts somewhere in between.
