2. 226 Teaching about the Future
thousands of journal and popular articles about leadership have also been
published. Wikipedia lists 230 degree programs on leadership1
just in the
US. So the topic is too extensive to summarize completely here.
The study of leadership is characterized by eras in which particular
research agendas were popular. After almost a century of study, how-
ever, no research agenda has proven to be completely satisfying in
providing a complete understanding of leadership.2
Era 1. Traits
The first approach was simply to try to distinguish what characteris-
tics made leaders different from followers (non-leaders). Leaders were
defined as the individuals who were in positions of authority; followers
as those not in such positions.

status, child-rearing practices, capacity, achievement, responsibility, par-
ticipation, status. The list goes on. In the end, however, the differences
between leaders and followers were not strong enough to be sure that
there was any real pattern.
Era 2. Situation
Researchers then turned to the situations or context that leaders found
themselves in. The purpose was to decide which personality traits were
appropriate for which situations. Hersey and Blanchard (1977) proposed
a theory of leadership that depended on two dimensions: the com-
petence and the commitment of the followers. Situations range from
low competence and commitment, which requires close supervision,
through medium levels, which requires high levels of support, to high
levels allowing large-scale delegation.
None of these approaches, however, produced strong results.
Researchers were not able to empirically support which traits were
appropriate for the different situations.
Era 3. Effectiveness
The third attempt changed the focus from traits to behaviors – not what
leaders were, but what they did – to be effective. Part of that approach was
to distinguish leadership styles. One of the most common distinctions
