The document summarizes the trait approach to leadership, which focuses on identifying innate qualities and characteristics that differentiate leaders from non-leaders. It discusses the early "Great Man" theories from the 1900s and historical shifts in trait perspective through the 20th century. Major leadership traits identified include intelligence, self-confidence, determination, integrity, and sociability. More recent research has linked the Big Five personality factors of extraversion, conscientiousness, neuroticism, openness, and agreeableness to leadership abilities. The trait approach provides benchmarks for leadership qualities but fails to definitively delimit traits.
