Best of the best: Who makes the most accurate decisions in expert groups?

Assumption/Hypothesis: "Those individuals in a group of experts who make decisions that are most similar to the decisions of others also make the best decisions."

"It has been shown time and again that experts who are good in their field are good in a similar way, whereas poor performers are bad in very different ways. Working on the basis of this observation, we developed this new method and tested it in various areas," says Ralf Kurvers, lead author and researcher at the Center for Adaptive Rationality at the Max Planck Institute for Human Development.
