Abstract
Deceivers are not protected from the effects of deception, and this chapter considers the effects on the deceiver from the biological adaptation, neuroscience, psychology, and communication perspectives. While deception is adaptive, it is constrained by the truth bias and the deceiver’s understanding of the target’s detection of deception. When deception occurs, multiple neuro-processes are activated in the brain. Those changes lead to cognitive and emotional loads that impair the deceiver’s ability to manage communication. Self-deception is an inevitable outcome of deception and, along with deception outcomes, alters the deceiver’s sense of self and sense of reality. These changes in the deceiver manifest in the interpersonal communication context.
