Deception

Querido Umbigo:

Deception is the act of convincing another to believe information that is not true, or not the whole truth as in certain types of half-truths.
Deception involves concepts like propaganda, distraction and/or concealment. Fiction, while sometimes manipulative, is not a deception unless it is portrayed as the whole truth.
In many cases it is difficult to distinguish deception from providing unintentionally wrong information. One of the reasons for this is that a person or an entire organization may be self-deceived.
