ShowcasesSome showcases of our complexity research: Prediction: 12-month El Niño forecastOur new prediction model makes it possible to give El Niño forecasts for up to one year in advance. Social Science: Mathematical social network modelUsing the game Battle of the Sexes, our researchers show how different social network structures have effect on overcoming conflicts of interest. Infrastructure: Solutions for railway disruptionsUsing a NWO grant we work on improving the resilience and reliability of the Dutch railway system. Climate change: Deadline for climate actionIn a study together with scientists in the UK we show that there are strict deadlines for taking climate action. Economics: The madness of peopleWe use complexity research to analyse financial systems, where a small event can trigger a change in beliefs and sudden collective action. Law: Legal analysis supported by complexity theoryOur analysis of the GDPR shows that this law may not effectively prevent discrimination based on sensitive traits like ethnicity and religious beliefs. Sociology: Success and LuckUsing complexity models we study the role of luck and positive feedback spirals in the determination of personal success. Economic Geography: The Principle of RelatednessWe developed a framework that systematically maps technological and research capabilities for all EU regions.
