Closure or need for closure are psychological terms that describe the desire or "need" some individuals have for information that will allow them to conclude an issue that had previously (for them at least) been clouded in ambiguity and uncertainty. Upon reaching this conclusion, they are now able to attain a state of epistemic "closure".
The term cognitive closure has been defined as "a desire for definite knowledge on some issue and the eschewal of confusion and ambiguity." Need for closure is a phrase used by psychologists to describe an individual’s desire for a firm solution as opposed to enduring ambiguity.
