the belief that something is untrue
Disbelief is not the same thing as a lack of faith. Lack of faith is the absence of absolute confidence that something is or will be true. Disbelief is absolute confidence that something is not true. Disbelief may make one a skeptic but sometimes it makes a character the only one with the confidence to tell the Emperor, "You have no clothes!"
syn. refusal to accept, distrust, find unconvincing, find false, unpersuadability
