This article describes SparkMaps as Hunome's visual tool for representing collective understanding and diverse viewpoints on specific themes or subjects. The platform aims to help groups see the breadth of their collective knowledge, reach shared understanding, and make better decisions based on that understanding. SparkMaps begin with an initial thought or idea that expands through collaborative contributions, covering themes like cultural adjustment, curiosity, AI limitations, future of work, misinformation, demographic shifts, universal basic income, and EU energy policy. The article outlines methods for using online meetings to build SparkMaps collectively, including starting with personal stories, reflecting on contributions, identifying knowledge gaps, and scheduling follow-up sessions for continued development. It mentions positive feedback from organizations like Systems Change Finland and Friends of Curiosity regarding the tool's effectiveness for discovering new connections and insights.
