In this episode of the Quillette Podcast, host Zoe Booth speaks with behavioural scientist Dr Dani Sulikowski about the sociocultural and evolutionary drivers behind collapsing fertility rates in Western societies. Drawing on emerging research and data from her own lab, Dr Sulikowski explores how intersexual competition among women, shifting gender norms, and declining testosterone levels in men may be contributing to a wider pattern of reproductive decline.

Their conversation covers the psychology of modern mating preferences, the unintended consequences of social narratives around motherhood and career, and the cultural implications of pronatalist and antenatalist ideologies. They also discuss contentious issues such as surrogacy, abortion, and assisted dying—all within the context of civilisational health and long-term population sustainability.

This episode offers a thought-provoking examination of the forces shaping human behaviour, fertility, and the future of Western societies.
