We look at several of Elon Musk’s business ventures, forays, and interests: (1) X.com; (2) SpaceX; (3) Tesla; (4) cryptocurrency; and (5) Twitter. We discuss Musk’s decision-making and see whether behavioural economics, especially prospect theory, can help us to better understand his...

Given their technical sophistication, it is easy to overlook the human choices that underpin predictive policing algorithms and, importantly, the basic structures of decision theory that it embeds. To make a problem amenable to algorithmic computation, the problem must be transformed, often...

The use of artificial intelligence (AI) and algorithms by intelligence agencies requires the capability to counter their use by rival agencies. A formal-technical development of this capability can be assisted by decision theory, including behavioural economics. Peter J Phillips and Gabriela...

The paper explores terrorist choice by applying two well-known theoretical frameworks: stochastic dominance and prospect theory. We analyse each pair of attack methods that can be formed from the RAND-MIPT database and the Global Terrorism Database (GTD). Instances of stochastic dominance are...

The large number of names on terrorism watch lists raises the problem of monitoring. Given the existing resource constraints and other logistical considerations, efficient and accurate ranking of individuals in terms of threat posed is of paramount importance. This process, however, may be...
