In her review of Playing the Lying Game: Detecting and Dealing with Lies and Liars, from Occasional Fibbers to Frequent Fabricators by Gini Graham Scott, Ngoc Bui notes:
[F]orensic psychologists and clinical psychologists would be most interested in the last chapter of the text on deceiving and perceiving lies and what to do if one is lied to or caught lying, given that their work deals with helping others (e.g., individuals, spouses, friends, family, and police) detect lying. Scott cites Paul Ekman, an expert on lying research, who states that detecting lies among those who truly believe their lies or have good control over their body, face, and voice is very difficult. However, some telling clues include increased blinking or pupil dilation, blushing, blanching, or facial sweating…While psychologists have been concerned with detecting others' lies, whether in criminal interrogation or clinical therapy situations, little is said about the benefits of lying. Is it ever ethical or appropriate to teach people how to engage in some minimal or less serious lying as a way of improving their social skills? Could adding (minimal) lying to someone's social skill set be helpful to them in relationships with friends, family, or coworkers?
