Professor Ralph Hertwig is a cognitive psychologist and decision scientist. He is Director of the Centre for Adaptive Rationality at the Max Planck Institute for Human Development inBerlin, Germany. His research examines models of bounded rationality such as simple heuristics, how people cope with risk and uncertainty, and ways to change behavior by boosting cognitive and motivational skills in the online and offline world. All three lines of research converge in the context of pressure points between the architecture of online information technologies and human cognition. For example, his research is concerned with behavioral interventions against the persistence and spread of misinformation in the digital world. He is also interested in the impact of digital media on key dimensions of democratic systems such as trust, polarization and participation. He has received numerous awards and honors, including the Gottfried Wilhelm Leibniz Prize. He is a member of the German National Academy of Sciences Leopoldina, the German Academy of Science and Engineering acatech, and the Berlin-Brandenburg Academy of Sciences.
