This observation is also valid for groups. In times of crisis, social risk factors (financial difficulties, political troubles, inequalities, turmoil on the international scene amongst others) are manageable one at a time. Once they start to cumulate, their potential for destabilisation increases, and the ensuing feelings of collective humiliation impel demoralised populations to form alliances with fanatical extremists (Moïsi, 2007). The first step in elaborating strategies for the early detection of collective violence is therefore to identify multiple risk situations and intervene before the groups concerned experience widespread emotional distress. The aim of this method, preventive resilience, is to bolster the constructive capabilities of the discontented masses while at the same time removing the temptation of an opportunistic alliance with fanatics (Cotter and Holleufer, 2008).
