It's really difficult to figure out. And there are times when you'd like to know whether that manager is giving you the straight skinny or, well, prevaricating. Occasionally I meet someone who tells me he can always tell whether or not so and so is lying. Don't believe him. It's more than difficult to tell whether or not a person's spinning a line.
Because of my business in executive development, I interview from 10 - 20 colleagues of a client as part of the diagnostic process. Political reasons for an interviewee to be deceptive are not far below the surface, so assessing truthfulness is of high import.
The academic discipline of lie detection has a long history beginning in the 1960s with a number of research scholars including Paul Ekman and Wallace Friesen. Ekman has become a world famous specialist, teaching that the best way to identify a dissembler is through his/her face. In his earlier studies he identified a basic set of expressions that are similar throughout the world: anger, disgust, fear, surprise, happiness and sadness. Along the way, he's catalogued more than 7,000 micro-expressions, subtly different.
Ekman's basic premise for catching a liar is that you cozy up to him, become a friend, get him talking and wait for the facial cues of lying (that model works for more than deception.). As the interviewee talks, there's a fleeting and momentary expression that doesn't fit the information that he's giving. And there you have it: he's a liar. In contrast, truth-telling has no fleeting facial micro-expression, no subtle, momentary facial tic.
The problem with this approach is that you've got to be trained and supervised to become effective. And, of course, being a very smart academic, Ekman consults with law enforcement groups all over the world to high fees. (That's a swell personal brand.)
Today's Times describes research on honesty that focuses not on facial animation or other nonverbals, but on words. According to a number of behaviorists, the new method is a lot like the old "Columbo" show where the interviewer or interrogator pretends to be an idiot, but goes about gathering a lot of evidence.
In one survey, researchers found that less-confrontational interrogations resulted in a "higher likelihood of confession." (Wonder if Cheney would believe that?) Content, they've found is more accessible to information gathering than nonverbals like sweating, fidgeting, eye-contact, or facial responses.
Liars tend to concoct a story that is tight and lacks detail. Truth tellers have no script and tend to recall a lot of detail, including extraneous stuff, and may even make mistakes. "They are sloppier."
Two researchers found one consistent difference: "People telling the truth tend to add 20 to 30 percent more external detail than do those who are lying." And if you return to the question, asking them in a different format, they'll add more and more detail. Inevitably, liars stick to one story.
What this means for my hour-long interviews is that I can return to previous issues from a different perspective, question the previous issues in a different context, and hitchhike on the interviewees information to go at the same issue again.
For example, let's suppose I'm trying to find out about my client's people skills. There are any number of questions that I can drop into the interview regarding different subjects as the conversation proceeds over the hour. In the following list, my underlying objective is to identify my client's people skills, even though I'm digging for a lot of other data:
How effective is Jim at people skills? What examples can you give me? Why do you think that example gives you a lot of information on his relationships? On a scale of 1 - 10 in personal effectiveness, where would you place him--with 10 being extremely capable? How do people in the organization think about Jim's people skills? Have you seen him in a conflict with his colleagues? When he gets frustrated, what is he liable to do or say? In those settings, how consistent is he? Let's suppose one of his reports is having difficulty with a project? How will he handle that? How would he go about helping her?
I can't imagine going at these questions in sequence or even in a straight-forward manner. They appear as a result of other statements and issues, and are dropped into the conversation regarding all kinds of issues such as strategic thinking, technological expertise, managing people, network development or the ability to manage power constructively. It's all a matter of what I call conversational hitchhiking.
The most important skill for identifying truth-telling or deception, though, is active listening. Coincidentally, I was trained as a singer, and my coaches emphasized listening, teaching me to listen to nuance, tone, pitch, diction, lyricism, phrasing, sound formation, language and many other attributes. As I moved out of singing into counseling, and then into full-time coaching, I found that listening training was key for assessing and coaching clients.
Effective questioning is profoundly important for all kind of business settings, from client relationships to managing people or coaching. But questioning is slightly less important than listening, especially when you have concerns about deception.
How successful have you been at identifying deception? How do you go about it?
