What if the most important skill a planetary health researcher could develop isn't statistical literacy — it's imagination?

In this episode of The Lancet Planetary Health In Conversation, host Matteo Simonetti sits down with Alastair Brown, Editor-in-Chief of The Lancet Planetary Health, to discuss a viewpoint published in the journal: "Health Punk: Speculative Methods for the Future of Planetary Health." The paper documents a course in which students were challenged to write science fiction as a way to break out of siloed disciplinary thinking. Many found it genuinely difficult.

Alastair argues that this difficulty is the point — that resistance to imagining radically different futures is not a neutral stance, but a political one. He draws a straight line between constrained thinking and the gap between what the evidence demands and what institutions are willing to attempt. The conversation also touches on AI, energy systems, the Wade-Dahl-Till valve, and why the punk in "health punk" matters as much as the health.
