Closure or need for closure (NFC), used interchangeably with need for cognitive closure (NFCC), are social psychological terms that describe an individual's desire for a clear, firm answer or peaceful resolution to a question or problem to avert ambiguity.
The term "need" denotes a motivated tendency to seek out information. The need for closure is the motivation to find an answer to an ambiguous situation. This motivation is enhanced by the perceived benefits of obtaining closure, such as the increased ability to predict the world and a stronger basis for action. This motivation is also enhanced by the perceived costs of lacking closure, such as dealing with uncertainty. A sense of closure is not usually possible with ambiguous loss, such as a missing person, and the hoped-for benefits, such as a sense of relief after the death of a person who inflicted harm, are not necessarily obtained.
