What makes a good and a great military leader? The myth of a divine, born leader is very popular but today we actually know better than this fiction. Science has given us the evidence to understand what traits and characteristics imbue a person with the skills and experience become a great leader. And we actually know how to select them based on the very different requirements in wartime and peacetime. It is also popular to talk about leadership and followership as two distinct functions; the term servant leader has become fashionable amongst military professionals as an attempt to delineate the boundaries between these two groups, yet still keep the hierarchy. Expert analysis is harder to find; for that we need to turn to science and a human psychologist. Sarah Chapman-Trim talks about making the least-worst decision (as opposed to the best one), the fallacy of the divine general, how we can train better leaders, and the dual-agency model of leadership. Sarah’s research paper (perhaps better understood with the title ‘Social identity as Alchemy’) is at https://www.army.mod.uk/media/24170/leadership-insight-no45-social-identity-as-a-leadership-tool.pdf
