Starting with the basic question “what influences our decision making?”, Vladas Griskevicius presented an excerpt of his recent research on the power of social norms to influence behavior. Although often overlooked by management, his field research provides evidence for the effectiveness of the salience of social norms to influence desirable outcomes such as green consumption, reduce excessive drinking, or engage in writing informative online reviews. We thank Vladas for his visit in Vienna and for sharing his expertise in the fields of evolutionary psychology, persuasion, communication, and social influence. (ulido)
