Social science approaches to the impact of severely stressful events o
n groups and communities have typically emphasized the vulnerability o
f affected populations and the need for intervention and assistance on
their behalf. Without denying the importance of such help, this paper
argues that communities-like individuals-are generally resilient and
hardy. They are able to cope with widespread danger and disaster, to m
aintain rational and adaptive problem-solving behaviors, and even to u
se the experience as a source of renewed strength. Reactions to the Gr
eat Plague of the 14th century and the aerial bombardment of cities in
World War II, and the adjustment of Holocaust survivors and the South
east Asian Boat People, are analyzed to illustrate these points.
