Global Trends 2030 Alternative Worlds is the fifth installment in the National Intelligence Council’s series, published in 2012, designed to provide a framework for future thinking. This report stimulates strategic thinking by identifying critical trends and potential discontinuities. It differentiates between megatrends—factors expected to play out in any scenario—and game-changers—key variables with unpredictable trajectories. As the worlds complexity increases, there is a growing focus on exploring scenarios or alternative worlds at this pivotal moment in human history. The report argues that the future is not predetermined but rather shaped by the interplay of megatrends, game-changers, and, most importantly, human agency. The ultimate aim is to inspire decision-makers, both in government and beyond, to engage in long-term planning that fosters positive futures while mitigating negative outcomes.
