Max Weber once remarked that bureaucracy’s power comes from its massing of expert and factual knowledges. It amasses this power, in part, by keeping much of its expertise and factual knowledge from public view. Only occasionally does someone with access reveal more of what’s going on behind the scenes, and how it might matter for our thinking about how facts are produced and contested, and what kinds of facts matter to policy makers and why. Sarah Ball is one such person.  In Behavioural Public Policy in Australia: How an Idea Became Practice (Routledge, 2024), the former public servant draws on interviews and ethnographic observation to chart the making of a behavioural public policy unit in the Australian public service, asking — and answering — questions about how the unit sought to make facts and establish expertise, and how the many meanings of behavioural insights were contested and accommodated along the way.

Sarah recommends Informality in Policymaking by Lindsey Garner-Knapp and others. Learn more about your ad choices.
