Crémieux on Fertility, Ozempic, IQ and Pit Bulls

In this episode of Quillette Cetera, Zoe Sankey speaks with Jordan Lasker—better known by his pen name Crémieux—the bioinformatician and writer whose contrarian analyses of genetics, demographics and medicine have drawn a following of hundreds of thousands on X.

They discuss why birth rates across the Anglosphere began falling after a Victorian obscenity trial, what Crémieux makes of the evidence on GLP-1 drugs like Ozempic and the panic over microplastics, and his own experience being mauled by a pit bull—which, he argues, is a question of nature, not nurture. They also turn to El Salvador’s transformation under Nayib Bukele, IQ testing and embryo selection, the tangle of politics and personality, free will, and the strange business of being Jewish and atheist at once.
