Can speculative evidence inform decision making?

Over at Superflux, our work investigating potential and plausible futures, involves extensively scanning for trends and signals from which we trace and extrapolate into the future. Both qualitative and quantitative data play an important role. In doing such work, we have observed how data is often used as evidence, and seen as definitive. Historical and contemporary datasets are often used as evidence for a mandate for future change, especially in some of the work we have undertaken with governments and policy makers. But lately we have been thinking if this drive for data as evidence has led to the unshakeable belief that data is evidence.
