Tests exist for evaluating personality, intelligence and memory. However, up to now, it was not easily possible to find out how good someone is at making decisions in risky situations. “Yet this is an important skill that has an enormous influence on many of our decisions,” says psychologist Edward Cokely, who came up with the idea of developing a quick test for this skill at the Max Planck Institute for Human Development in 2007. In the intervening five years, he has carried out 21 sub-studies in 15 countries with colleagues from Max Planck Director Gerd Gigerenzer's group at the Institute in Berlin and the Michigan Technological University. One of the results of the studies is the first quick test for establishing an individual’s risk intelligence.
