Power leads to greater errors in forecasts, according to new research led by social psychologist Dr Mario Weick at the University of Kent. The research, to be published by the Journal of Experimental Social Psychology, shows that when people feel powerful they become more optimistic and less accurate in predicting the completion time of forthcoming tasks. The research examined for the first time the planning behaviour of powerful people and found that power drastically reduced the accuracy of forecasts with error rates soaring up to 70%. Dr Weick, a Research Fellow at the University’s School of Psychology, explained: ‘Time is a crucial factor in people’s everyday lives. Whether they are teachers, policy makers or engineers, people routinely plan their work and estimate the time it will take to accomplish tasks. Interestingly, people often underestimate the time it takes to accomplish tasks. This bias is known as the planning fallacy and derives from a too narrow focus on the envisaged goal.
