Hooker studied the relationship between homosexuality and psychological development. The test subjects were separated into a group of homosexuals and a group of heterosexuals. Hooker gave the test subjects three different psychological tests: the Rorschach, the Thematic Apperception Test, and the Make-A-Picture-Story Test. Hooker found no significant differences in the results of the tests. Therefor, Hooker concluded that homosexuality was not based on environmental factors because of the similar test scores. In 1973, from Hooker’s findings, the American Psychiatric Association no longer referred to homosexuality as a psychological disorder. Then in 1975, the APA released a statement publicly stating that homosexuality was not a mental disorder. There have been countless studies to determine whether or not being homosexual was determined by your genetics. Among the most illustrious were the series of studies conducted by Pillard and Michael Bailey. Bailey was a psychology professor at Northwestern University. They found that homosexuality was in fact largely determined biologically and not environmentally influenced. Pillard and Bailey examined both identical and fraternal twin brothers. They also examined unrelated brothers who had been adopted. In their findings, they discovered that if one identical twin was homosexual, then there was a 52% chance that the other brother was homosexual also. In fraternal twins, there was a 22 percent chance of both of the brothers being homosexual. While in the unrelated adopted brothers, there was only a 5% chance of that occurring. Bailey and Pillard’s findings have been debated for many years. Pillard points out that most of
