Max Planck Society
"The Max Planck Society is Germany's most successful research organization. Since its establishment in 1948, no fewer than 18 Nobel laureates have emerged from the ranks of its scientists, putting it on a par with the best and most prestigious research institutions worldwide. The more than 15,000 publications each year in internationally renowned scientific journals are proof of the outstanding research work conducted at Max Planck Institutes – and many of those articles are among the most-cited publications in the relevant field."

"The Max Planck Institute for Human Development is dedicated to the study of human development and education. Researchers of various disciplines – including psychology, education, sociology and medicine, as well as history, economics, computer science and mathematics – work together on interdisciplinary projects at the Berlin Institute. The research questions they examine include how people make effective decisions even under time pressure and information overload, which effects the institution of school has on students’ development and learning processes, how the interaction between behaviour and brain function changes over the lifespan, as well as how human emotions change in a historical context and how they have affected the course of history itself."

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.
