Future paths

Scenarios address the question: What kind of future could emerge from the turbulent changes shaping our world? Trends and policies move us in certain directions, but fundamental choices, ours to make, reveal strikingly different paths.

The Global Scenario Group, precursor to GTI, introduced a simple "taxonomy of the future" to organize the complex junctures and possibilities for the future. At the highest level, three broad channels – Conventional Worlds, Barbarization, and Great Transitions – radiate from the present into the imagined future. These are worlds of gradual evolution, precipitous decline, and transformative progression. Of course, these broad categories include numerous scenario variants. Here, we consider two variants for each, or a total of six global scenarios.
