Gerd Gigerenzer is a world-renowned psychologist and one of the most recognised experts on the psychology of decision-making. He is Director Emeritus at the Max Planck Institute for Human Development and Director of the Harding Center for Risk Competence. According to the Gottlieb Duttweiler Institute, Gigerenzer is one of the 100 most influential thinkers in the world. Gerd Gigerenzer is the specialist on the subject of "intuition" and " subconscious intelligence". Against the prevailing concept of management consultants and guidebook authors to proceed as analytically as possible when making decisions and to weigh up the advantages and disadvantages exactly, Gigerenzer puts forward the thesis that human intelligence does not function like a calculating machine. For him, logic is only one of many tools of intelligence. Decisions are made intuitively far more often - from the gut. According to Gigerenzer, we decide particularly well when we don't think about it, when decision-making time is short and forces an intuitive approach. Prof. Gerd Gigerenzer was Director at the Max Planck Institute for Human Development from 1997 to 2017. Prior to that, he served as Director of the research area "Adaptive Behaviour and Cognition" (ABC) at the Max Planck Institute for Human Development and the Max Planck Institute for Psychological Research, Munich, as well as Professor at the University of Chicago and John M. Olin Distinguished Visiting Professor at the School of Law of the University of Virginia. Since 2008, Gerd Gigerenzer has been Director of the Harding Centre for Risk Competence, which was based at the Max Planck Institute for Human Development until 2020 and has been affiliated with the University of Potsdam since 2020. He is also the founder and partner of Simply Rational - The Institute for Decision. He is a member of the German Academy of Sciences (Leopoldina) and the Berlin-Brandenburg Academy of Sciences, an honorary member of the American Academy of Arts and Sciences and the American Philosophical Society. He holds honorary doctorates from the University of Basel and the Open University of the Netherlands and is a Batten Fellow at the Darden Business School of the University of Virginia.
