Why Are People Gay?

Over time there has been an increasing amount of evidence that homosexuality has a biological basis, Overby said; such as hair whorls that are counter-clockwise, left handedness, right hand digit ratios (the ring fingers being longer than the index fingers), and altered hypothalamus structure (also meaning altered pheromones).

“I’m not making this up,” Overby said. There have been studies on identical twins showing that they often share the same sexual orientation but the chances are a lot lower if they are fraternal twins. There is no definitive “gay gene” even though human beings have shown definite signs of having a “gaydar.”

Unfortunately, Overby said that there’s limited research on public opinion but even with the limits it is believed that 41 percent of the population believe homosexuality to have a biological basis—numbers that go far past the 13 percent that believed the same thing in 1977.

From 2007 until 2008 there has been a Cooperative Campaign Analysis Project, internet-based with 20,000 registered voters (although Overby only used 1,834 of them in his presentation) asking questions regarding the etiology of homosexuality, attitudes toward gay adoption, and attitudes toward gay civil unions and presidential vote choice. There are a wide range of control variables: demographic and social, political, and even personality. There may be problems with Internet surveys since they limit the number of Americans voting, but the digital divide is closing rapidly–20 percent of Americans have no land lines, instead having cell phones only and 75 percent of Americans have Internet use at home.
