So losing our belief in free will could have negative effects on those around us. It could also undermine our own success in life. In a recent study, Tyler Stillman of Florida State University, working with Vohs, Baumeister and others, found that people who said they believed strongly in free will also tended to have more positive expectations about their career success. Is this just delusional thinking? Apparently not. When Stillman and colleagues asked supervisors to rate the work of their employees, those with a greater belief in their own free will were generally rated as performing better than those with weaker beliefs (Social Psychological and Personality Science, vol 1, p 34).
