The article addresses the question of how sufficiency for the imprudent may be ensured. Imprudent conduct includes both spectacular acts such as jumping from heights into water, and everyday acts and omissions such as neglecting to fasten one’s seat-belt. We argue that to avoid thoroughly bad or insufficient situations, one must pay attention to an important and often neglected concern of avoiding insouciance. The latter tells us not to stand idly by when people are about to act in ways that may irrevocably land them in insufficient situations. The policies and actions needed to avoid insouciance are most plausibly justified on paternalistic grounds; in fact, they cannot be justified nonpaternalistically. Although controversial, we argue that paternalistic interventions are often justifiable in the service of preserving sufficiency.
