Another conclusion in search of a study

A computer algorithm developed at Stanford is able to determine a person's sexuality with surprising accuracy. The computer correctly identified 81% of men and 74% of women as either straight lesbian or gay. The conclusion they threw at this is that sexuality is determined by hormones prior to birth.
I'm not surprised at the ability of the computer to determine whether people are straight, gay or lesbian from photographs, especially when they took their study sample from on line dating sites. People want to draw attention to themselves, and they know whom they are targeting.
The study was conducted on only whites, and also did not include transgender confused and bisexual ultra desperate. When five or more pictures were presented, the accuracy jumped to 91% with men and 83% with women.
Simple enough facts, the average person viewing those pictures was able to predict sexuality 61% for men and 54% for women, exactly 20% less often than the computer algorithm did. I can believe that, this is not rocket science. But what about if they fed pictures to the computer of those people when they were small children? I some how doubt the results would hold up. I know plenty of boys who looked and acted feminine as children who are fathers and married, and also know plenty of women who were tomboys that are married mothers.
Feed the computer those pictures, then try it again with pictures taken when they were in grade school, middle school, high school, and prior to their "coming out".
I would be willing to bet that with a little adjusting, a computer could accurately identify drug addicts and drunks as well as a host of other things. We are the product of our life experiences and choices. The result of too many helping of cake is clearly visible when meeting me, I assure you.
People who live in alternate life styles show the changes those life styles make on them. That is what I believe the computer has identified, not some hormonal imbalance their mother had when they were a mere sixteen cells. This is being fed to us because the people who live abominable life styles want us to believe they are not at fault for their bad choices. The gay gene has already failed, this is the next option. Why? Deep down, they feel some guilt about their choice. It matters not that we could care less whether they are gay as long as they give eight hours work for eight hours pay.
