Communicating science in an age of bewilderment; or, a brief technological tectonics of our communication landscape

We live in bewildering times. Unusual politicians and political movements are rising to the fore, geopolitical maps are being redrawn, old certainties are collapsing, and knowledge — both good and bad — is flowing differently from ever before. Based on the belief that effective communication of science requires understanding of our communication landscape, in this article I offer a brief `technological tectonics' of our current communication landscape, exploring how shifts in communication technologies have made certain politics and certain flows of knowledge possible. I then offer three paths for action — in reflection, practice and advocacy — for those interested in the communication of science.
