Closure (psychology)

Closure or need for closure (NFC) (used interchangeably with need for cognitive closure (NFCC)) are psychological terms that describe an individual's desire for a firm answer to a question and an aversion toward 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 missing deadlines. According to Kruglanski et al., need for closure exerts its effects via two general tendencies: the urgency tendency (the inclination to attain closure as quickly as possible) and the permanence tendency (the tendency to maintain it for as long as possible). Together, these tendencies may produce the inclinations to seize and then freeze on early judgmental cues, reducing the extent of information processing and hypothesis generation and introducing biases in thinking.

The level of the need for cognitive closure is a fairly stable individual characteristic. It can affect what information individuals seek out and how they process it. However, this need can be affected by situational factors like time constraints. For example, in the presence of a high need for closure (induced using time constraints), individuals are more likely to use simple cognitive structures to process information.

The need for closure is thought to be a fairly stable dispositional characteristic that can, nonetheless, be affected by situational factors. The Need for Closure Scale (NFCS) was developed by Arie Kruglanski, Donna Webster, and Adena Klem in 1993 and is designed to operationalize this construct and is presented as a unidimensional instrument possessing strong discriminant and predictive validity.

A person with a high need for closure prefers order and predictability, is decisive and closed-minded, and is uncomfortable with ambiguity. Someone rating low on need for closure will express more ideational fluidity and creative acts. Items on the scale include statements such as "I think that having clear rules and order at work is essential to success," and "I do not like situations that are uncertain." Items such as "Even after I've made up my mind about something, I am always eager to consider a different opinion," and "I like to have friends who are unpredictable" are reverse scored.

Composed of 42 items, the scale has been used in numerous research studies and has been translated into multiple languages. Although Webster and Kruglanski (1994) treated the Need for Closure Scale as unidimensional (i.e., as measuring a single factor), the scale actually contains two orthogonal factors, decisiveness and need for structure. Thus, using a total scale score can overlook effects for each factor and complicate interpretations. In 2007, Roets and Van Hiel tried to resolve this issue by revising the scale so it would measure only one thing. They came up with a set of new decisiveness items that provided a viable alternative for the old Decisiveness subscale of the NFCS, which was poorly related to the other NFCS facet scales and had questionable validity. The new items were developed with explicit reference to decisiveness but formulated in such a way that they relate to the need rather than to the ability to decide. In 2011, Roets and Van Hiel created an abridged and empirically validated NFC scale consisting of only 15 items from the original NFC.
