Backcasting is a strategic foresight and anticipatory design method that operates in the reverse direction of traditional forecasting. Rather than predicting the future by extrapolating past or present trends, it involves envisioning a “preferred future” or ideal state, and then working backward to determine the specific interventions, policies, and actions required to reach that desired outcome.
In the context of systemic design, backcasting relies on “retroductive logic”. This form of reasoning is essential for collective futures-creation, as it actively makes room for creative “leaps of imagination” during value-laden and emotional inquiries involving a diverse range of stakeholders.
While transdisciplinary researchers and experts use back-casting alongside alternative long-term scenarios to help resolve complex, real-world societal problems, systems thinkers emphasize that the approach must remain grounded. Even when designing interventions backward from an ideal goal, practitioners must not deny the fact that futures are inherently unknown, unpredictable, and uncontrollable.
