The Extrapolation Factory is a design-based research studio for participatory futures studies, founded by Chris Woebken and Elliott P. Montgomery. The studio develops experimental methods for collaboratively prototyping, experiencing, and impacting future scenarios.

Central to these methods is the creation of hypothetical future props and their deployment in familiar contexts such as 99¢ stores, science museums, vending machines, and city sidewalks. With this work, the studio is exploring new territories for democratized futures by rapidly imagining, prototyping, deploying, and evaluating visions of possible futures on an extended time scale.
