Potential Surprise Theory as a Practical and Theoretical Cornerstone of the Uncertainty‐Based Perspective on Risk

open access: yesRisk Analysis, Volume 46, Issue 6, June 2026.
ABSTRACT From all the knowledge that would emerge as relevant to it over infinite time, a risk analysis must be based on the cross‐section available at its undertaking. This creates a knowledge gap, which can lead to surprises. To address a similar problem in economic decision‐making, G. L. S. Shackle developed potential surprise theory (PST).

Fugitive Junctures: Life‐Seeking, Route‐Finding and the Mobile Ensemble at Kenya's Borders

open access: yesTransactions of the Institute of British Geographers, Volume 51, Issue 2, June 2026.
Short Abstract Fugitivity has become an important conceptual frame to understand the illegalised mobilities of contemporary migrants in conjunction with enslaved people's historical lines of flight as spatial praxes to seize their own freedom. Thinking from Kenya, and drawing on research with migrants, border officials, activists, police and smugglers,
