The subjects of the study were asked to solve a particular problem-solving task previously used in other psychology studies researching problemsolving.
In one study conducted by organizational psychologists Jennifer Mueller, Jack Goncalo, and Dishan Kamdar, 55 employees rated the responses of nearly 300 of their (unidentified) coworkers to a problem-solving task for both creativity (the extent to which their ideas were novel and useful) and as evidence of leadership potential.
