I was particularly struck by chapter five on psychological testing of sexual preferences. I've always been curious about how it's possible to take this intangible, abstract feeling of sexual attraction and turn it into hard data. It is natural for a psychologist to attempt to transform abstract data into concrete data with which he can diagnose and treat the symptoms of a disorder. Now, diagnostic tests alone can reveal valuable information about a person's inner psychology. However, their terrible power lies in the interpretation and application of the results. People love to correlate things together. Gay? They'll say something like “oh, she always wore pink. No wonder why he's gay,” despite the fact that the color pink may have no real connection to being gay. People feel comfortable if they see the link between the effect and the cause. .Kinsey wrote of this feature: “Only the human mind invents categories and tries to force facts into separate boxes” (p.123, Discover). In other words, it simply opened up an avenue for humans to use them to segregate themselves with evidence. So did other psychologists such as Kauth, Storms, Benjamin and Klein who continued to create further tests to allow humans to differentiate their sexuality. Maybe that's why people are desperate for something tangible to test for, like a "gay" gene. In 1993, Dean Hamer, an American geneticist, claimed to have found the particular gene in gay men. However, there was no definitive evidence for this claim (Hamer, 2000). However, it is absolutely dangerous to use this test on people for biological reasons. I'm afraid to imagine the impossible scenarios of mothers aborting their children because of their "gay" gene or forcing a soldier to take the test to find out his preference. I can easily imagine this because it has happened to deaf people before. A certain group of people actually carry the deafness gene. My good friend comes from a family of nine siblings, all deaf because both of her parents had the “deaf” gene. Fortunately their parents embraced deaf culture and did not worry about their children being deaf. It could easily be a different situation for his parents. They could have tested this gene first and decided not to have children. Then my good friend will not exist. There is a good example of a nature-nature theory gone wrong.
