Global Trends 2030: Alternative Worlds "is the fifth installment in the National Intelligence Council’s series aimed at providing a framework for thinking about the future. As with previous editions, we hope that this report will stimulate strategic thinking by identifying critical trends and potential discontinuities. We distinguish between megatrends, those factors that will likely occur under any scenario, and game-changers, critical variables whose trajectories are far less certain. Finally, as our appreciation of the diversity and complexity of various factors has grown, we have increased our attention to scenarios or alternative worlds we might face. We are at a critical juncture in human history, which could lead to widely contrasting futures. It is our contention that the future is not set in stone, but is malleable, the result of an interplay among megatrends, game-changers and, above all, human agency. Our effort is to encourage decision makers—whether in government or outside—to think and plan for the long term so that negative futures do not occur and positive ones have a better chance of unfolding."
