The study identifies a significant gap between the theoretical potential of individual behavior shifts to reduce emissions and the actual results achieved through behavioral interventions. While comprehensive behavioral changes could theoretically offset the average global citizen's per capita emissions, real-world interventions typically achieve only 10% of that potential. The authors identify four 'Priority Shifts'—reducing gas-powered vehicle use, decreasing air travel, lowering residential fossil fuel consumption through structural changes, and reducing animal product consumption—as the most impactful actions. Conversely, 'Supplementary Shifts' like composting have minimal impact. The research highlights a geographic imbalance, with a surplus of studies in the US and EU and a deficit in high-emitting nations like China, India, Brazil, and Indonesia. The most effective behavioral tools for driving change are choice architecture and commitment devices, while information-based approaches are the least effective.

The authors analyze how violence spreads in space and time during civil wars, distinguishing between relocation diffusion (shifting violence) and escalation diffusion (expanding violence). Using a modified joint count statistic and Monte Carlo simulations on ACLED event data from Bosnia, Kosovo, Burundi, and Rwanda, the study finds that violence typically expands in scope, supporting the theory that irregular warfare lacks demarcated front lines.
