One of the aims of the Global Risks Report is to encourage individuals and organizations to think critically and creatively about how they can respond to a rapidly evolving risks landscape. With that in mind, in the Risk Reassessment section we invite selected risk experts to share their insights about developments in our understanding of risk. In this year’s report, Roland Kupers writes about resilience in complex systems, while Michele Wucker calls for organizations to pay more attention to cognitive bias in their risk management processes.
