Lying in popular culture, and patterns of deception in the face, gestures, posture, vocals, and verbal narrative
“Lie to Me” is the title of a now-defunct show wherein the main character, Cal Lightman (Tim Roth), attempts to determine fact from fiction, truth from fantasy. The show was based on real behavioral science; the scientific consultant for the show? None other than Dr Paul Ekman, whose name bears resemblance to the main character.
Of course, I have as many criticisms of the show as compliments. They should have broadened the scope of the show a bit to avoid the predictable scenes where facial expressions and pupil dilation are examined ad nauseum. Latter episodes avoided the science altogether to make the show a kind of dramatic soap opera. Instead, discussions of how expressions of emotion might be related to underlying cognition would make sense, factoring in individual behavioral patterns and psychopathological traits.
Not that the show should have used such jargon, or focused too heavily on the science aspect. That would be interesting only to a small subset of the population (i.e., people like me). The real science could be breezed over quickly, with enough verisimilitude to keep the “technical” people on board, but with the real focus on good story development, which “Lie to Me” lacked. The “structure” of the show was too chaotic, with episodes failing to properly build atop previous episodes, and melodrama replacing good character development. Cal Lightman’s character could have been better modeled after the main character in “House.” In “House,” the legendary diagnostician Gregory House is both impulsive and pensive, two seemingly contradictory characteristics that make him more profound and more interesting. In contrast, Cal Lightman was impulsive, but lacking the profundity and depth of the real Paul Ekman.
The focus on “lie detection” by the general public is, I think, a mistake. After all, what is a lie? Is a “white lie” whose intent is altruistic considered “deceptive"? What about benign lies, such as saying “Yes, it’s beautiful” when your spouse asks how her dress looks on her? Is that mendacity, or is it compassion? Are there times when telling a lie can be far more kind than speaking the truth? The answer is yes, I would say.
Although I think the zooming in on lie detection is itself a mistake, depriving one of seeing a larger emotional picture, I simultaneously (and somewhat contradictorily) find some level of fascination in it, perhaps because so many other people find it fascinating. First and foremost, there is no “magic” in this process. There is no single facial expression that determines that someone is lying. Instead of looking for a single “tell,” I believe it is more prudent to look at the whole emotional picture—the aggregate of all facial, gestural, postural, vocal, and verbal observations, coupled with context and a behavioral “baseline” of the person being evaluated. Following the preceding process allows one to not just determine “truth,” but to determine what is meant rather than merely what is said.
Direct and Indirect Deception
I categorize deception into two broad categories: direct and indirect. Excluded from lying or deception are false statements or implications that are made but that, in context, are obviously false. An example would be the “emotional lying” of actors. It is implicit that they are playing a role. A gray area might be a fortune teller: is fortune telling purposeful deception, or is it implied that they’re providing entertainment?
On direct deception, I make no sub-categories, and I define it in a very clear sense. It is a direct, untrue statement meant to deceive. For example, if someone who committed a crime flatly denies doing so, then he is making a direct lie. In contrast, if he dances around the issue, responding with statements that are, technically, true statements, but with intent to deceive, then he is making an indirect lie. Think of former US president Bill Clinton in this regard. When asked if he had had sexual relations with a White House intern, he persistently danced around the question, re-defining terms so as to avoid being caught in a direct lie. The clue in this case is the failure to directly answer the question that he clearly wished to avoid.
Are there general clues to deception—direct or indirect—that can be useful across a broad spectrum of the population? My response is yes, though it comes with the general proviso that “lie detection” shouldn’t be the sole goal. If the goal is to determine if someone is lying, then you are faced with a situation in which you must make a black and white choice between truth-teller or liar. It is rarely so simple in real life, and perhaps no less complex in the interrogation room. Further, it is too easy to be susceptible to pride (no one wants to be “fooled” by the liar) and confirmation bias (bias toward supporting one’s own beliefs on the matter).
With the aforementioned provisos in place, there are generalized patterns that one can discern to augment the belief that someone is being deceptive. Most are applicable to both direct and indirect lying, though indirect lying carries some additional clues. There are three particular affective states that might be applicable to someone trying to deceive. They are: apprehension, guilt, and enjoyment.
