This paper investigates a type of “post-digital” practice that constructs “evidence” instead of “data” and relies on the “narrative-driven” instead of “data-driven” method to influence public opinions. This approach to digital landscape practice addresses the dilemma in the “post-truth era,” in which public opinions are driven by emotion and empathy rather than objectivity and facts. The paper argues for a post-digital culture by cultivating a sense of criticality in designers towards data collection and data-driven methods. With these new conceptual frameworks in understanding data, objectivity, evidence and fact, landscape architects could play an important role in influencing public decision-making by constructing narratives that are needed when humanities are faced with unprecedented social and environmental uncertainties.
