Incorrect information may arise as a result of error or intentional distortion. Errors may occur from computer or other mechanical equipment that is insufficiently programmed or inaccurately used. They may occur as the result of insufficient research or lack of information. Incorrect information may be phrased in such a way that it gives a false impression. This may be deliberately misleading or unintentionally so, due to error or to being unrelated to its context. Intentionally false information may take the form of propaganda or indoctrination, false evidence, false confession, advertising abuse and other deceptions. The results may include confusion, especially if there is conflicting information, prejudice, conflict, alienation, ignorance, a sense of defeatism or apathy, unfair trial, imprisonment (political or for perjury and contempt of court). It may serve to maintain existing injustices, inequalities and exploitation and strengthen government control, dictatorship, monopoly, organized crime and corruption.
