Galinsky collaborated with psychologist Joris Lammers of Tilburg University and Ernestine Gordijn and Sabine Otten of the University of Groninengen on the study. These findings are the first to clarify when, and lend insight into why, power leads to behavioral approach, or action. [continue reading…]
