The field of political psychology has demonstrated that there are quantifiable psychological traits that impact the perceived efficacy of political leaders in the US, Russia and specific case studies of individual British Prime Ministers. In a recent study, Sam Rohrer drew on this literature to analyse psychological traits linked to great leadership for 20th century British Prime Ministers, and finds that self-confident, decisive and charismatic leaders are looked upon most fondly by history.
