11.1 Trait Approaches to Leadership

Intelligence

General mental ability, often called “IQ” in everyday language, has been related to a person’s emerging as a leader within a group. Specifically, people who have general high mental abilities are more likely to be viewed as leaders in their environment (House & Aditya, 1997; Ilies, Gerhardt, & Huy, 2004; Lord, De Vader, & Alliger, 1986; Taggar, Hackett, & Saha, 1999). We should caution, though, that intelligence is a positive but modest predictor of leadership, and when actual intelligence is measured with paper-and-pencil tests, its relationship to leadership is a bit weaker compared to when intelligence is defined as the perceived intelligence of a leader (Judge, Colbert, & Ilies, 2004). In addition to having a high IQ, effective leaders tend to have high emotional intelligence (EQ). People with high EQ demonstrate a high level of self awareness, motivation, empathy, and social skills. The psychologist who coined the term emotional intelligence, Daniel Goleman, believes that IQ is a threshold quality: It matters for entry- to high-level management jobs, but once you get there, it no longer helps leaders, because most leaders already have a high IQ. According to Goleman, what differentiates effective leaders from ineffective ones becomes their ability to control their own emotions and understand other people’s emotions, their internal motivation, and their social skills (Goleman, 2004).

Big 5 Personality Traits

Psychologists have proposed various systems for categorizing the characteristics that make up an individual’s unique personality; one of the most widely accepted is the “Big Five” model, which rates an individual according to Openness to experience, Conscientiousness, Extraversion, Agreeableness, and Neuroticism. Several of the Big Five personality traits have been related to leadership emergence (whether someone is viewed as a leader by others) and effectiveness (Judge et al., 2002).

Self-Esteem

Self-esteem is not one of the Big Five personality traits, but it is an important aspect of one’s personality. The degree to which a person is at peace with oneself and has an overall positive assessment of one’s self worth and capabilities seem to be relevant to whether someone is viewed as a leader. Leaders with high self-esteem support their subordinates more and, when punishment is administered, they punish more effectively (Atwater et al., 1998; Niebuhr, 1984).
It is possible that those with high self-esteem have greater levels of self-confidence and this affects their image in the eyes of their followers. Self-esteem may also explain the relationship between some physical attributes and leader emergence. For example, research shows a strong relationship between being tall and being viewed as a leader (as well as one’s career success over life). It is proposed that self-esteem may be the key mechanism linking height to being viewed as a leader, because people who are taller are also found to have higher self-esteem and therefore may project greater levels of charisma as well as confidence to their followers (Judge & Cable, 2004).

Integrity

Research also shows that people who are effective as leaders tend to have a moral compass and demonstrate honesty and integrity (Reave, 2005). Leaders whose integrity is questioned lose their trustworthiness, and they hurt their company’s business along the way. For example, when it was revealed that Whole Foods Market CEO John Mackey was using a pseudonym to make negative comments online about the company’s rival Wild Oats Markets Inc., his actions were heavily criticized, his leadership was questioned, and the company’s reputation was affected (Farrell & Davidson, 2007).

There are also some traits that are negatively related to leader emergence and being successful in that position. For example, agreeable people who are modest, good natured, and avoid conflict are less likely to be perceived as leaders (Judge et al., 2002).

Despite problems in trait approaches, these findings can still be useful to managers and companies. For example, knowing about leader traits helps organizations select the right people into positions of responsibility. The key to benefiting from the findings of trait researchers is to be aware that not all traits are equally effective in predicting leadership potential across all circumstances. Some organizational situations allow leader traits to make a greater difference (House & Aditya, 1997). For example, in small, entrepreneurial organizations where leaders have a lot of leeway to determine their own behaviour, the type of traits leaders have may make a difference in leadership potential. In large, bureaucratic, and rule-bound organizations such as the government and the military, a leader’s traits may have less to do with how the person behaves and whether the person is a successful leader (Judge et al., 2002). Moreover, some traits become relevant in specific circumstances. For example, bravery is likely to be a key characteristic in military leaders, but not necessarily in business leaders. Scholars now conclude that instead of trying to identify a few traits that distinguish leaders from nonleaders, it is important to identify the conditions under which different traits affect a leader’s performance, as well as whether a person emerges as a leader (Hackman & Wageman, 2007).
