Large-scale infrastructures are typically part of development projects that are global in ambition and local in their impacts. While anthropology has a decent track record of using ethnographic methods in the study of infrastructure, it typically lacks the capacity to provoke statements or attitudes regarding larger development plans. Scenario workshops, initially developed by researchers in the field of foresight studies, turn out to be productive tools in eliciting assessments of the present by talking about possible futures. The European Research Council project InfraNorth conducted scenario workshops in two locations in Canada and Norway in 2023, in which four scenarios were presented and discussed. Apart from speculations about what the future might bring, these discussions provided ethnographic insights that went beyond what we had found before through more traditional means of ethnography. We suggest that scenarios and scenario workshops have the potential to offer ethnographic windows into infrastructural presents by talking about the future.
