When we began as editors of Lawrence Erlbaum Associates’ Organization and Management Series, our lofty aim was to publish works, both theoretical and empirical ones, that would nudge the boundaries of organization studies. Lord and Brown’s book admirably achieves this aim. The authors present an innovative theory that, we predict, will drive empirical research. The theory supplies a new way to think about an old topic, leadership. It does so by drawing heavily on ideas about social cognition and self-regulation. Reading Lord and Brown’s book is truly eye-opening. Enjoy the adventure
