For no scientific reason, we’ve all been brainwashed into believing that homosexuality is not by choice, that homosexuals are born that way.
But eight major studies of identical twins in Australia, the United States and Scandinavia during the last two decades all have arrived at the same conclusion: homosexuality primarily and overwhelmingly (90%) is an acquired disposition, instead of genetic.
The findings of those studies are presented in Chapter 10, “Twin Studies: the strongest evidence,” of Neil E. Whitehead, Ph.D., My Genes Made Me Do It! – Homosexuality and the scientific evidence (Third edition, Oct. 2013). (You can download the book, free, in PDF format here; or buy a copy here.)
Dr. Neil Whitehead is the author of over 140 published scientific papers. His Ph.D. is in biochemistry, 1971, New Zealand. He was employed as a scientist with the New Zealand government for 24 years, at the United Nations for 4 years, and more recently as a scientific research consultant to Japanese universities on the effects of radiation exposure.
