One review found that, across seven studies (total N = 2,284) where personal-history data were used to forecast success in management, the average validity was a respectable .38. When personal-history data were used to predict sales success, it was.50, and, when used to predict success in science/engineering, it was .41 (Reilly & Chao, 1982). Another study examined the relationship between college experiences and later managerial performance at AT&T (Howard, 1986). The choice of major (humanities, social science, business versus engineering) and extracurricular activities both validly forecast the interpersonal skills that are so critical to managerial behavior.
