Doubt, a status between belief and disbelief, 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).The concept of doubt covers a range of phenomena: one can characterise both deliberate questioning of uncertainties and an emotional state of indecision as "doubt".
