It is sometimes said that one of the casualties of the general suspicion and mistrust that permeated the old Soviet Union was that the distinction between truth and other motivations to believe tended to break down. Upon hearing a purported piece of information, the reaction was not 'Is this true?' but 'Why is this person saying this? - What machinations or manipulations are going on here?' The question of truth did not, as it were, have the social space in which it could breath.
