Are gay people more creative

Mystery solved: this is why younger sons are more often homosexual

He knew himself that it sounded strange, he suspected that there would be protests and many questions. He also knew: he would not be able to answer it. It was in the late 1990s when Ray Blanchard, a sexologist who now works at the University of Toronto, nevertheless published a study that until recently remained a mystery.

Blanchard asked 302 homosexual men and 302 straight men about their biography and compared their answers. At that time, laypeople and experts alike were racking their brains over whether homosexuality was innate and therefore unchangeable, or whether it had been learned and thus theoretically there was the possibility of “re-educating” gay men and lesbian women.

But the sexologist did not find any significant differences between the two groups. With one exception. An older brother, he wrote at the time, increased the younger brother's likelihood of being homosexual by 33 percent. Blanchard called this the "fraternal birth order effect". Today it is also known as the “older brother effect”.

It is always the younger ones who tend to be gay

As expected, the study caused a lot of fuss. Which theory did the finding speak in favor of? Was it the environment that gave birth to homosexuality? Or was there a biological connection that was unknown?
