Important research into leadership traits, and among the first to challenge traditional trait-based theory, was the work conducted by Ralph Stogdill.
Stogdill wrote a paper in 1948 (Personal Factors Associated with Leadership: a Survey of the Literature, Journal of Psychology) that cast doubt on trait theory.
I am grateful to James Scouller, an expert coach, thinker, and writer on leadership, for the contribution of most of the technical content on this article, and for the collaboration in editing it and presenting it here. Aside from what follows here, Scouller's
expertise in leadership theory is evidenced particularly in his 2011 book "The Three Levels of Leadership", which I commend to you.
Stogdill analysed data and findings from over a hundred leadership-related studies, across the following 27 groups of factors:
Initiative, persistence, ambition, desire to excel
Physique, energy, health
Integrity and conviction
Fluency of speech
Happiness, sense of humour
Emotional stability and control
Social and economic status
Judgement and decision (US-English, judgment)
Social activity and mobility
Insight (self, others, wider environment)
Energy, daring and adventurousness
Social skills (sociability, tact)
Stogdill found there wasn't much agreement on the key traits.
Indeed, it was clear that if all the findings were combined, the list became too long to be useful as a guide for selecting future leaders.
Stogdill's conclusions actually still hold firm today, and show no sign of being undermined in the future.
This extract from Organizational Behaviour (1985), by David Buchanan and Andrzej Huczynski, reflects very well modern thinking about this:
"The problem [in attempting to classify/measure leadership capability] is that research has been unable to identify a common, agreed set of [leadership] attributes. Successful leaders seem to defy classification and measurement from
Stogdill was one of the first to point out that a person doesn't become an effective leader just because he or she has certain traits.
He argued that a successful leader's characteristics must be relevant to the demands of the leadership situation - that is, the specific challenges faced and the abilities, hopes, values and concerns of the followers.
