Trust fools you into remembering that your partner was more considerate and less hurtful than they actually were, say psychologists who examined the role of trust in biasing memories of transgressions in romantic partnerships.
People who are highly trusting tended to remember transgressions in a way that benefits the relationship, remembering partner transgressions as less severe than they originally reported them to be. People low on trust demonstrated the opposite pattern, remembering partner transgressions as being more severe than how they originally reported them to be, they concluded.
