Cognitive Biases in Volunteered Geographic Information (VGI)

Together with Dr Rul von Stülpnagel from the Center for Cognitive Science at the University of Freiburg we explore the validity and reliability of opinion-based Volunteered Geographic Information (VGI). Geo-positioned information crowdsourced from the citizens carries great potential for urban planning. In our case study we look closer at citizens’ reports of dangerous cycling spots in two German cities. Are such subjective opinions representative of the real cycling danger in the given location?
