Daniel Kahneman is widely regarded as the most influential psychologist alive. He won the Nobel Prize in Economics (2002) for his work on judgment and decision-making under uncertainty, much of it done jointly with his late collaborator Amos Tversky. He is the author of the bestselling books Thinking, Fast and Slow and Noise: A Flaw in Human Judgment (written with Olivier Sibony and Cass Sunstein).

Daniel Kahneman — Dyads, And Other Mysteries

Patrick Weller is emeritus professor of politics and public policy at Griffith University and the author or editor of some forty books.

Pat wrote what was the first (and may still be the only) Westminster-system equivalent to Robert Caro's epic meditation on Lyndon Johnson: a detailed study of how Australian Prime Minister Malcolm Fraser wielded power. First published in 1989, it's a fascinating study of how one individual climbed into the hermit-crab-shell that is the prime ministership and made it his own.

Pat is also the author of two other detailed studies of Australian political leaders, and the definitive history of cabinet government in Australia.

Pat's work offers a picture of how human institutions – in this case, Westminster cabinets – work in practice and on a day-to-day level. Understanding the messiness, the beautiful malleability of the institutions, and their human bottlenecks has helped me build a more accurate model of the world – useful for predicting how governments may both respond to and utilise powerful new technologies.

"Just because I consulted doesn't mean I didn't dominate": How prime ministers really govern — Patrick Weller

Danielle Wood is an Australian economist and the current chair of the Australian Productivity Commission.

Had a lot of fun chatting with Dani about how she's making sense of AI and its implications for policy. We discuss:
whether AI will be more like the internet or the Industrial Revolution,
where in the AI stack the profits will ultimately flow (and why it might not be the model layer),
why diffusion is the "main game" for Australian policymakers,
whether there's a case for government support of data centres,
why the AI jobpocalypse story is too crude (and why humans may still have jobs even under transformative AI),
whether AI will turn out to be a normal or abnormal technology, or both,
and why in either case Australia shouldn't follow the EU in legislating an AI Act.

How Can Australia Get a Piece of the AI Action? — Danielle Wood

Part 3 of a three-part immigration series this week. Martin Parkinson (economics) available here; Mark Cully (history) available here.

Mike Pezzullo ran the Australian Customs and Border Protection Service (2013-2014), then the Department of Immigration and Border Protection (2014-2017), then the Department of Home Affairs (2017-2023). For more than a decade across those three roles, he was responsible for how Australia selects migrants, screens for risk, and thinks about social cohesion under stress.

We discuss the central but underappreciated fact about how Australia selects migrants: the diversity of our intake is a happy accident of global migration flows, not engineered policy. We also walk through how the visa system actually screens for security and character, why Pezzullo doubts the Bondi terrorist's father would have been refused a student visa in 1998 even with today's tools, what a 2027 China-Taiwan blockade would mean for the Australian migration system in real time, and a never-aired proposal for fixing Australia's "permanent temporaries" problem — a constitutional amendment Pezzullo calls "the Pezzullo special." We finish with: should "populate or perish" return as defence policy?
