The investigations of leader traits are always by no means exhaustive. In recent years, several studies have made comprehensive reviews about leader traits that have been historically studied. There are many ways that traits related to leadership can be categorized; however, the two most recent categorizations have organized traits into (1) demographic vs. task competence vs. interpersonal and (2) distal (trait-like) vs. proximal (state-like):
Demographic, task competence and interpersonal leadership Based on a recent review of the trait leadership literature, Derue
et al stated that most leader traits can be organized into three categories: demographic, task competence, and
interpersonal attributes. For the demographics category, gender has by far received the most attention in terms of leadership; however, most scholars have found that male and female leaders are both equally effective. Task competence relates to how individuals approach the execution and performance of tasks. Hoffman
et al grouped intelligence,
conscientiousness, openness to experience, and
emotional stability into this category. Lastly, interpersonal attributes are related to how a leader approaches social interactions. According to Hoffman
et al, Extraversion and Agreeableness should be grouped into this category.
Distal (trait-like) vs. proximal (state-like) Recent research has shifted from focusing solely on distal (dispositional/trait-like) characteristics of leaders to more proximal (malleable/state-like) individual differences often in the form of
knowledge and
skills. The hope is that emergence of proximal traits in trait leadership theory will help researchers elucidate the old question whether leaders are born or made. Proximal individual differences suggest that the characteristics that distinguish effective leaders from non-effective leaders are not necessarily stable through the life-span, implying that these traits may be able to be developed. Hoffman
et al examined the effects of distal vs. proximal traits on leader effectiveness. They found that distal individual differences of achievement
motivation, energy, flexibility, dominance, honesty/integrity,
self-confidence, creativity, and
charisma were strongly correlated with leader effectiveness. Additionally, they found that the proximal individual differences of interpersonal skills, oral communication, written communication, management skills, problem solving skills, and decision making were also strongly correlated with leader effectiveness. Their results suggested that on average, distal and proximal individual differences have a similar relationship with effective leadership. == Trait-leadership model ==
