Crémieux on Fertility Collapse, Ozempic, IQ & Why Pit Bulls Are the Way They Are

Zoe Sankey sits down with Crémieux (the pen name of researcher Jordan Lasker), the formerly anonymous X writer-researcher whose data threads on genetics, demographics and metabolic drugs have drawn a following of more than 260,000 — including some very prominent readers. It's a wide-ranging conversation. They cover collapsing fertility rates and the Victorian obscenity trial he argues helped set them falling; his case that dog breeds — pit bulls especially — behave the way they were bred to, and why he thinks people resist that; what he makes of the evidence on GLP-1 drugs like Ozempic and retatrutide, microplastics, and the wellness industry; El Salvador's transformation under Nayib Bukele; IQ testing, genetics and embryo selection; populism, personality and politics; free will; and being Jewish and atheist at once. ⏱️ Chapters: 00:00 Intro — who Crémieux is and how he built his following 02:24 Fertility collapse and the Bradlaugh–Besant trial 05:00 Silphium, abortion and the long human history of family planning 06:00 Strong convictions, and why he wants to live forever 07:49 Brian Johnson, longevity and the wellness-hype problem 10:56 Microplastics: what the evidence actually shows 13:24 Zinc, Accutane and the biology of acne 18:08 Ivermectin, Demodex mites and skin 20:22 Pet rats, lab rats, and which animals we call "cute" 22:56 UFOs and the Trump-era document releases 25:11 Pit bulls: breeding, behaviour and public denial 30:06 Ira Glass, greyhounds and virtue-signal dog ownership 34:11 GLP-1 drugs: Ozempic, retatrutide and the medical turnaround 36:00 His own weight loss, muscle and travel-for-work 37:57 Próspera, El Salvador and Bukele's gang crackdown 42:49 Duterte, Hanania's Kakistocracy and populism 45:42 IQ, classical liberalism and organising society 47:12 China, dumping, open-source AI and pharmaceutical free-riding 50:36 Tariffs and the destination-based cash flow tax 51:49 Hope, ageing, and the generational wealth question 55:14 Truth-seeking, reform, and why people don't change their minds 56:46 Jewishness, identity and defining who counts as a Jew 59:11 Antisemitism, zero-sum thinking and its long tradition 1:01:05 The future of Israel and the Hilonim birth rate 1:04:04 IQ tests, Mensa and gaming the matrices 1:05:27 Embryo selection and raising smart kids 1:08:36 Nature, nurture and what mothers influence 1:09:20 Politics shaping personality — and the La Piere study 1:14:30 The Big Five, intelligence and conscientiousness 1:18:14 Free will: Pinker vs. Harris 1:20:38 The name "Crémieux" and Adolphe Crémieux 1:21:59 Wrap-up — 📩 Subscribe to Quillette: https://quillette.com 🎧 Listen on Apple & Spotify 🐦 Follow Quillette: https://twitter.com/Quillette — Guest: Crémieux — https://x.com/cremieuxrecueil | Substack: https://cremieux.xyz — Referenced in this episode: • Rob Brooks, "The Tragedy of the Unwanted Child" (Quillette) — https://quillette.com/2022/06/24/the-tragedy-of-the-unwanted-child-what-ancient-cultures-did-before-abortion/ • The Bradlaugh–Besant trial (1877) — https://en.wikipedia.org/wiki/Bradlaugh%E2%80%93Besant_trial • Richard Hanania, Kakistocracy — https://link.amazon/B0g92Tesm • Herasight (embryo screening) — https://www.herasight.com • Orchid (embryo screening) — https://www.orchidhealth.com Learn more about your ad choices.
