Experimentally analyzing the impact of leader positivity on follower positivity and performance

This field experimental study examined the role that positive leadership plays in producing effective leader and follower outcomes. Specifically, a sample of engineers (N = 106) from a very large aerospace firm were randomly assigned to four experimental conditions. Two conditions involved assigning these engineers to a low and high problem complexity condition. The other two conditions represented high versus low conveyed leader positivity. The results indicated a positive relationship between the leaders' positivity and the followers' positivity and performance as well as a negative relationship between problem complexity and follower positivity. The study limitations, needed future research, and practical implications of these findings conclude the article.
