Risk perception is not only an individual but also a social phenomenon. The experiment presented in this video examines the development of perceived risk over the course of a communication chain: The first person got a balanced overview on a chemical and its risks then information was passed on from person to person. WOLFGANG GAISSMAIER elaborates how this set up led to an amplification of risk perception and the distortion of facts and explains how the makeup of the group affects the final attitudes towards the risk in question.
