While individuals brimming with confidence or arrogance and showing natural authority may appear potential leaders, a dominating attitude or self-obsession often leaves such individuals being worst bosses, says a study.
In a study conducted by University of Amsterdam researchers, group members rated the most narcissistic leaders as most effective, but in fact the groups led by the greatest egotists never chose the best candidate, the Daily Mail reported.
Psychologist Barbora Nevicka, who led the study, said: "There's no doubt narcissism can sometimes be useful in a leader. But, good leaders facilitate communication by asking questions and summarising the conversation - something narcissists are too self-involved to do."
The findings are to be published in the journal Psychological Science.
