Are nations with women leaders more or less likely to go to war with other nations? Government professor S.P. Harish and his co-author addressed that question in a recent article appearing in the Journal of Political Economy, a top outlet in social science. Their study took an historical quantitative approach by examining nations led by queens or kings during a more than 400-year period from 1480 to 1913.
