Doubt, a status between belief and , involves uncertainty or distrust or lack of sureness of an alleged fact, an action, a motive, or a decision. Doubt brings into question some notion of a perceived "reality", and may involve delaying or rejecting relevant action out of concerns for mistakes or faults or appropriateness. Some definitions of doubt emphasize the state in which the mind remains suspended between two contradictory propositions and unable to assent to either of them (compare paradox).
