When asked why May-Britt Stumbaum, a researcher at the Center for Intelligence and Security Studies (CISS) at the Bundeswehr University in Munich, is interested in security policy, she smiles: „I was always pretty good at math.“ What Stumbaum alludes to: When she went to elementary school in the early 1980s, schoolchildren were required to participate in regular nuclear emergency evacuation drills. But with 1,200 students and only 100 seats in the fallout shelter, „it quickly became clear that not everyone would fit,“ Stumbaum says. An impetus that, over time, developed into a fascination for politics and for the question that is still on her mind today: Why people make which decisions.
