Micro Expressions and Detecting Lies

When it comes to detecting lies and deception, the more reliable information and training we have at our disposal, the more effective we will likely be. Based on several international studies, most people rely on eye movement to tell if someone is lying or not. The common belief is that when people look away - gaze aversion - they must be lying because "they couldn't look me in the eye!" Countless research studies failed to support this belief, and in fact, this belief is so widespread that many times the liar will make a point to look you dead in the eye, because he too believes if he looks away you may not believe his lie. This is called "impression management".  

The video below is a short clip on micro expressions with Paul Ekman. By having good training with investigative interviewing and criminal interrogations, knowing what to look for and how to apply it within the contex of the interview, and adding skills like understanding and reading emotions and micro expressions in people will provide you with the much needed edge in your interviews and interrogations and assessments of truthfulness and deception in people.



Complexities of Human Behavior

Human beings are complex. You don't have to be a scientist or an academic researcher of human nature to know that is a true statement, you just have to live amongst us humans for a period of time and you understand. Well, you understand that humans are complex...not necessarily understand human behavior!

The point is, no matter how long we live or how long we have been in a particular profession, or how many experiences we have or how much training we have taken, there is always more to learn. One of the things I was always surprised with as a police supervisor was that many officers take one course on "interview and interrogation", which may be anywhere from 1 to 5 days, and they believe they have all the training they need in that area. That is simply not true. There is SO much to learn, and after 25 years I am still learning!

Police officers have mandatory training they must take each year, from firearms training to domestic violence issues, to how to use the latest computer databases. That is all well and good, but one of the things that police officers do the most, from the rookie on patrol to the seasoned homicide detective, is TALK TO PEOPLE. And not just talk to people like in a social setting or a cocktail party, they have to talk to people in a way to elicit as much relevant information from them while assessing for signs of deception and truthfulness. And they have to talk to people who are under stress, who have just been traumatized, who are under the influence of drugs or alcohol, who have elevated levels of anger and hostility, who may have memory issues, and who may or may not want to cooperate and provide them information. There are many, many more factors and complexities that make the "simple" act of communicating with and obtaining information from people so complex for the law enforcement professional.

This is one of the main reasons that it is so important to continually update your skills relating to interview and interrogation, read the latest information on detecting deception studies, associate with professional organizations on and off-line, read professional trade magazines, and attend formal training courses and academic conferences. Humans are complex...keep learning more and more about them.


Detecting Deception

There is a lot of information on the web that may or may not be accurate relating to distinguishing between truthful information and deception. I came across this video on detecting deception today which covers a lot of common beliefs about when someone is lying. Detecting deception is not easy, and studies have shown that most people are roughly accurate between 45%-55% of the time. In essence, their "lie detector" may as well be a coin-toss!

The problem is that people can take a 10 minute video like this covering an incredibly complex subject matter, and then apply the information within their interpersonal relationships and cause more problems than they solve...and be wrong about 50% of the time! The other problem is that most people believe they are naturally good at detecting lies. I conducted an informal survey a while back and the majority of people rate themselves at or above 80% accurate when identifying if someone is lying, so their confidence is high but their accuracy is likely much lower.

The most important thing is to get the right training and information that is supported through academic research as well as having been applied successfully in the field within real-life interviews and interrogations.
