A Summary of The Research on Leaders' Big Five Personality in The Past Twenty Years

Big Five Personality is one of the important tools for detecting leader personality differences and identifying leadership behavior or effectiveness. Relevant research in the past 20 years had been popular. From the content dimension, it could be roughly divided into three main stages, the personality trait theory based on functionalist psychology, the personality trait association theory based on situational theory and the trait theory revival period based on statistical analysis. From the perspective of research methods, using network big data and media interviews to get the leader's personality data had innovative value in recent years. From the research trend, more and more researchers paid attention to the adjustment variables of the Big Five Personality's influence on leadership behavior and leadership performance, such as leadership power level, environmental factors, work autonomy, and interpersonal communication.
