Deception

Deception, beguilement, deceit, bluff, mystification and subterfuge is the act of propagating beliefs in things that are not true, or not the whole truth (as in half-truths or omission). Deception can involve dissimulation, propaganda, and sleight of hand, as well as distraction, camouflage, or concealment. There is also self-deception, as in bad faith.
