The one trait successful leaders share

We all know that a person with past leadership experience and a true leader can be two completely different job candidates. That's where Leslie Pratch comes in.

A clinical psychologist, Pratch has evaluated hundreds of candidates for CEO and other top management positions at Fortune 500 companies to predict who will succeed and who will not. Her new book, Looks Good On Paper, distills down the one trait she thinks is essential for successful leaders to have. 

Great leaders are great active copers, Pratch explained to me earlier this week over coffee. By active coping, Pratch means the ability to adapt creatively and effectively to challenges and change. An active coper quickly recovers from setbacks, opens up to the people around her and is aware of her own motivations, strengths and shortcomings. In the constantly changing world that we will in, it is critical that leaders posses this trait, says Pratch. 

By evaluating potential job candidates based on this one trait, Pratch tells me she has successfully predicted the outcome of the leaders tenure 98% of the time over a ten year period.

IN CASE YOU MISSED IT

• Japanese companies aim to push more women into management. After Prime Minister Shinzo Abe recently announced policies aimed at filling 30% of managerial positions with women by 2020, private companies are following suit. Toyota, Shiseido and others are working to create voluntary action plans that they will unveil by year-end, targeted at getting more women into executive roles. Caroline Kennedy, the U.S. ambassador to Japan, is viewed as partly responsible for the country's sudden interest in gender diversity.   WSJ

• Did Clinton announce her presidential run on The Daily Show? Not really, but it's still fun to think about. Host Jon Stewart asked the former secretary of state what "shape" she would like her next office to be. Clinton responded, "I think that the world is so complicated, the fewer corners that you can have, the better.” The allusion to the Oval Office by the best known potential 2016 candidate sent the audience into a frenzy.   Quartz

When pursuing gender diversity, there is no one-size-fits-all solution. Measures that work in some countries, might fail spectacularly in others. Cultural context matters.

Researchers discuss their findings in <em>Harvard Business Review</em> on why strategies to promote women vary across cultures.
