New large scientific study further muddles the field about genetics and sexual preference

Sexual preference is for zero point zero percent determined by genetics

A new enormously large top statistical study now claims that our genetics determine only for a small part same-sex sexuality and not in one gene. There is so much nonsense in this study (and a little bit more how it’s wrongly reported) that it’s hard to decide where to begin.

The easiest is, first to know what reality is and then to contrast that with the hot air here sold as science. So, let’s do that. So that you can easily refute the nonsense that people will say based on this fake “news.”

The Truth

● Almost all men and most women report a sexual preference.
● Sexual preference shows in that for deep sexual bonding, one needs someone of one gender or the other.
● Most people have a heterosexual (other-sex) orientation and a minority (3% in men and 8% in women) have a homosexual (same-sex) orientation. (Others may be asexual, demi-sexual or bisexual.)
● This orientation becomes forever hardwired in the human brain at a very early age, probably before birth. What exactly causes this is not known yet.
● One may choose behavior but not this orientation. Forgoing this need for sexual bonding leads by most people to unbearable loneliness which may show in sexual compulsion.
● Different from orientation, behavior and attraction can change, to a certain degree, with or without therapy. But one can’t change the need for sexual union with someone of one particular gender and not the other.
● Same-sex preference because of anti-homosexual sentiments in society, is not always noticed or expressed.
● Sex with someone not of one’s preference enlarges loneliness and one can get addicted to such behavior as it’s not the real thing for them. By far, most same-sex behavior is by heterosexuals because they’re 95% of the population and often compulsive about it (finding no deep bonding).

There are many details known about all of this but this is the big picture and if you keep this in mind, you won’t get confused.

The Nonsense

● Homosexuals. The researchers themselves admit one of the greatest flaws in their study but that doesn’t make the flaw go away. And the problem is actually much larger than they assume. They did not by any means study sexual preference. They studied sexual behavior. That is not the same at all. There are so many more heterosexuals than homosexuals, so that most of the same-sex behavior that was studied says something about heterosexuals having same-sex sex, and very little about homosexuals having sex! Let me repeat: This study reports mainly about homosexual sex by heterosexuals. Not what everyone reports!

● Statistics. Statistics give a correlation, not a cause. A large statistical study can more easily distinguish between an accidental and a causal correlation but even the largest most likely correlation doesn’t show cause. Here, half a million subjects make it possible to reject many fake correlations but doesn’t show real ones with more certainty. The large size study does not mean more certainty in the findings. It only means, less false findings.

● Lying. Also in anonymous questionnaires, most people lie about their sexual life. My proof: The most progressive sex clinic in the Netherlands in the ’70s had an anonymous intake questionnaire for clients. The total of their self-reported behavior and problems did not at all correspond with a tally of what therapists in the subsequent therapies found. There is no basis to believe any of this self-reporting.

● Twin Studies. This study is a continuation of the assumption that sexual behavior is partly determined by our genetics because that’s what twin research teaches. Yet, medical research is utterly in the dark about behavior of twins. It assumes that more identical behavior of identical twins compared to non-identical twins must come from genetics. It also assumes that more identical behavior of twins that grew up together compared to twins that were separated at birth must come from non-genetic influences. They don’t seem to know that identical twins often have opposite characters (introvert/extrovert, etc.). Further, they often share everything, making the non-genetic influences more identical than between non-identical sibs. And twins who were separated at birth shared the first nine months together, which is completely overlooked. And most important in the formation of sexual orientation.

● Anti-Gay Bias. They blatantly and unashamedly tried to study homosexual preference and not heterosexual preference. It’s the old concept of this must be illness all over again.

● Sick. They studied “ever versus never had a same-sex partner.” But we know that people who never had same-sex sex are a tiny minority. You can’t understand general human sexuality by only studying a tiny ultra-frustrated or ultra-homophobic group. (Besides what I mentioned above that by far, most of the “ever” group will be heterosexual.) (After they ignore the known continuum, they “conclude ” “that there is no single continuum from opposite-sex to same-sex sexual behavior.” Duh.)

● Gender. The study finds no difference between men and women. But we all know that women are more flexible in their sexual gender choice. This shows that there cannot be much value in the whole study at all. One report says it so nicely in this euphemistic sentence: “It’s a reminder that, that [sic] like most human behaviors, sexual behavior is complex.”

● Oppression. The worst aspect of this shoddy work is that this “there is no Gay Gene” will again be used by cure-the-gays “therapists” claiming that science has shown again that our genetics don’t force us so we can freely choose — to become, be and stay heterosexual. And claiming that very many genes are very subtly involved in our sexual behavior feeds into chemo-psychiatry that claims that behavior comes from our genes, epi-genes, and biochemistry. If not happy with it, take our newest pills.

There’s probably much more wrong with this study but this is what I could write up quickly before Shabbat. What a bunch of shameful baloney anyway. Trying to properly communicate the claptrap doesn’t make it any better. Still, I think it’s not a good oversight that the Israeli media don’t report (but: properly) this prominent though faulty study.

About the Author
MM is a prolific and creative writer and thinker, previously a daily blog contributor to the TOI. He often makes his readers laugh, mad, or assume he's nuts—close to perfect blogging. He's proud that his analytical short comments are removed both from left-wing and right-wing news sites. None of his content is generated by the new bore on the block, AI. * As a frontier thinker, he sees things many don't yet. He's half a prophet. Half. Let's not exaggerate. Or not at all because he doesn't claim G^d talks to him. He gives him good ideas—that's all. MM doesn't believe that people observe and think in a vacuum. He, therefore, wanted a broad bio that readers interested can track a bit what (lack of) backgrounds, experiences, and educations contribute to his visions. * This year, he will prioritize getting his unpublished books published rather than just blog posts. Next year, he hopes to focus on activism against human extinction. To find less-recent posts on a subject XXX among his over 2000 archived ones, go to the right-top corner of a Times of Israel page, click on the search icon and search "zuiden, XXX". One can find a second, wilder blog, to which one may subscribe too, here: or by clicking on the globe icon next to his picture on top. * Like most of his readers, he believes in being friendly, respectful, and loyal. However, if you think those are his absolute top priorities, you might end up disappointed. His first loyalty is to the truth. He will try to stay within the limits of democratic and Jewish law, but he won't lie to support opinions or people when don't deserve that. (Yet, we all make honest mistakes, which is just fine and does not justify losing support.) He admits that he sometimes exaggerates to make a point, which could have him come across as nasty, while in actuality, he's quite a lovely person to interact with. He holds - how Dutch - that a strong opinion doesn't imply intolerance of other views. * Sometimes he's misunderstood because his wide and diverse field of vision seldomly fits any specialist's box. But that's exactly what some love about him. He has written a lot about Psychology (including Sexuality and Abuse), Medicine (including physical immortality), Science (including basic statistics), Politics (Israel, the US, and the Netherlands, Activism - more than leftwing or rightwing, he hopes to highlight reality), Oppression and Liberation (intersectionally, for young people, the elderly, non-Whites, women, workers, Jews, LGBTQIA+, foreigners and anyone else who's dehumanized or exploited), Integrity, Philosophy, Jews (Judaism, Zionism, Holocaust and Jewish Liberation), the Climate Crisis, Ecology and Veganism, Affairs from the news, or the Torah Portion of the Week, or new insights that suddenly befell him. * Chronologically, his most influential teachers are his parents, Nico (natan) van Zuiden and Betty (beisye) Nieweg, Wim Kan, Mozart, Harvey Jackins, Marshal Rosenberg, Reb Shlomo Carlebach, and, lehavdil bein chayim lechayim, Rabbi Dr. Natan Lopes Cardozo, Rav Zev Leff, and Rav Meir Lubin. This short list doesn't mean to disrespect others who taught him a lot or a little. One of his rabbis calls him Mr. Innovation [Ish haChidushim]. Yet, his originalities seem to root deeply in traditional Judaism, though they may grow in unexpected directions. In fact, he claims he's modernizing nothing. Rather, mainly basing himself on the basic Hebrew Torah text, he tries to rediscover classical Jewish thought almost lost in thousands of years of stifling Gentile domination and Jewish assimilation. (He pleads for a close reading of the Torah instead of going by rough assumptions of what it would probably mean and before fleeing to Commentaries.) This, in all aspects of life, but prominently in the areas of Free Will, Activism, Homosexuality for men, and Redemption. * He hopes that his words will inspire and inform, and disturb the comfortable and comfort the disturbed. He aims to bring a fresh perspective rather than harp on the obvious and familiar. When he can, he loves to write encyclopedic overviews. He doesn't expect his readers to agree. Rather, original minds should be disputed. In short, his main political positions are among others: anti-Trumpism, for Zionism, Intersectionality, non-violence, anti those who abuse democratic liberties, anti the fake ME peace process, for original-Orthodoxy, pro-Science, pro-Free Will, anti-blaming-the-victim, and for down-to-earth, classical optimism, and happiness. Read his blog on how he attempts to bridge any tensions between those ideas or fields. * He is a fetal survivor of the pharmaceutical industry (, born in 1953 to his parents who were Dutch-Jewish Holocaust survivors who met in the largest concentration camp in the Netherlands, Westerbork. He grew up a humble listener. It took him decades to become a speaker too, and decades more to admit to being a genius. But his humility was his to keep. And so was his honesty. Bullies and con artists almost instantaneously envy and hate him. He hopes to bring new things and not just preach to the choir. * He holds a BA in medicine (University of Amsterdam) – is half a doctor. He practices Re-evaluation Co-counseling since 1977, is not an official teacher anymore, and became a friendly, powerful therapist. He became a social activist, became religious, made Aliyah, and raised three wonderful kids. Previously, for decades, he was known to the Jerusalem Post readers as a frequent letter writer. For a couple of years, he was active in hasbara to the Dutch-speaking public. He wrote an unpublished tome about Jewish Free Will. He's a strict vegan since 2008. He's an Orthodox Jew but not a rabbi. * His writing has been made possible by an allowance for second-generation Holocaust survivors from the Netherlands. It has been his dream since he was 38 to try to make a difference by teaching through writing. He had three times 9-out-of-10 for Dutch at his high school finals but is spending his days communicating in English and Hebrew - how ironic. G-d must have a fine sense of humor. In case you wonder - yes, he is a bit dyslectic. If you're a native English speaker and wonder why you should read from people whose English is only their second language, consider the advantage of having an original peek outside of your cultural bubble. * To send any personal reaction to him, scroll to the top of the blog post and click Contact Me. * His newest books you may find here:
