Decision Making under Deep Uncertainty and the Great Acceleration The Role of Experts and Policy Analysis in a World in Transition

Addressing vulnerability and promoting security
May 07, 2025 | Rand Corporation

In a period marked by unprecedented growth in human activity and its impacts on the planet, some type of societal transformation is inevitable. Successfully navigating these tumultuous times requires scientific, evidence-based information as an input into society’s value-laden decisions, at all levels and scales. In his paper for the Rand Corporation, Robert Lempert poses the question how experts should best inform society’s attempts to navigate when both experts and decision makers are uncertain. Decision Making under Deep Uncertainty (DMDU) offers an answer to this question as it can repair the fractured conversations among policy experts, decisionmakers, and the public. The author explores how DMDU reshapes policy analysis to better align with the demands of a rapidly evolving world and offers insights into the roles and opportunities for experts to inform societal debates and actions toward more-desirable futures. https://www.rand.org
