If aliens were to come to our planet and review the recent findings of YouGov, you could forgive them for thinking so.
In 2005, the New York Times published an article with a catchy headline that sent waves through the LGBT world. Titled "Straight, Gay, or Lying," the article reported on study by researchers at the University of Chicago that failed to find 50/50 arousal patterns in a specific sample of men. Of course there is no requirement for bisexuals to be attracted to men and women in exactly the same way. Of course showing men pornography and measuring their erections is an imperfect measure of sexuality at best. Of course one sample of men is not representative of all men. Unfortunately, none of those important details, details that the scientists themselves pointed out, spoke loudly enough to drown out the power of that sound bite. Such is the nature communication in our media-saturated world.
