It ain’t what you don’t know that gets you into trouble.
It’s what you know for sure that just ain’t so.
Mark Twain (not necessarily)

4CF Stranger Futures is a serious board game. It was designed specifically for professional foresight applications in which the collective intelligence of participants is needed to question assumptions regarding the future of a given area and to identify disruptive changes. The game, partially inspired by RAND’s Assumption-Based Planning (ABP) methodological framework and the Delphi method, is unique in combining playfulness with a focus on the validity and usefulness of insights.

The rules of 4CF Stranger Futures are flexible so that the game can be played in a variety of modes: The simplest mode is most useful whenever the goals of the workshop are focused on enhancing the assumption-questioning skills of participants and their ability to come up with alternative futures. More complex game modes are available whenever well analysed, actionable insights are needed. In such cases a deeper assessment of the validity of insights is incorporated into the game, providing the possibility of producing an analytical report based directly on the results.  

4CF Stranger Futures has proven highly useful in a variety of topics and applications, ranging from the future of climate change resilience, through cybersecurity, to the future of the payments industry.

Goals of the game:

  • Use the collective intelligence of participants to challenge assumptions about the future in order to uncover alternative futures, disruptions and/or unexpectedly vulnerable assumptions
  • Enhance the participants ability to “use the future” – consciously de-bias their reasoning, consider various scenarios and disruptive events, challenge their assumptions and avoid naive trend extrapolations

Who and why should play it?

  • If you, your team, or the experts you involve in your projects are trying to cope with the complexity of the future, the speed of change and uncertainty – 4CF Stranger Futures is meant for you. Whether you’re trying to come up with solutions to one of the world’s most complex challenges, an innovative new product or marketing plan, an out-of-the box idea, or a winning strategy, it’s definitely worth making sure early-on that your assumptions aren’t misleading you and that the future won’t be stranger than you have ever imagined (because it probably will!).
