Moving away from the dichotomy of heterosexual or homosexual, Dr. Alfred Kinsey and hiscolleagues developed the Heterosexual-Homosexual Rating Scale, a seven-point scale ranging from 0 to 6. The scale runs from exclusive heterosexuality (0) to equally heterosexual and homosexual (3) to exclusively homosexual (6).
