Researchers found two particular limitations to trait theory and therefore started looking more at "what leaders do" rather than "who leaders are." The two limitations were that (a) traits had less practical relevance than leader actions and (b)

Correlations between leader traits and leader effectiveness were weak.

Explanation:

The trait theory also known as dispositional theory is the study of the personality of humans. Psychologists are interested in how of traits i.e. the habitual patterns of thought, behavior and emotion are measured.

Researchers have found out that there is a correlation between leaders and traits shown. The personality of leaders has an impact on their attitude, behavior and their perception about things.

The two limitations to trait theory as posited by researchers are:

a. Traits had less practical relevance than leader actions and

b. Correlations between leader traits and leader effectiveness were weak.

Different individuals possess different personality. An individual might possess leadership traits and still not be an effective leader.
