I am quoted extensively in this CNN article about criticism and praise in the workplace.
The article also quotes two interesting studies:
The study, done by the University of Michigan Business School several years ago, compared team performance to the frequency of praise and criticism given within the teams.
The best-performing teams used about six times as many positive comments for every negative one. It found that the worst performing teams, on average, used three negative comments for every positive one.
American psychologist, John Gottman, has found a similar ratio for positive and negative comments from spouses leading to happier marriages.
This is a topic we work with extensively because constructive feedback (both negative and positive) is so important for creating a happy workplace. Check out some of our other articles on this below.
