Former CIA Polygraph Examiner Shares His Secrets to Believable Lying

Stop Lying About the Way Your Characters’ Lie

by Dan Crum


During my time in the CIA as a polygraph examiner and investigator I came across terrorists and criminals and learned one very important lesson…they are just like you and me.

The amazing thing about people is that we all are manufactured out of the same parts and our physiologies are primarily the same. Which means no matter where in the world you travel, no matter who you talk to we are all alike in the way we communicate sincerity and deception.

I teach people to know when someone is lying. Probably one of the most common questions I get asked is whether these skills work in reverse. Can I teach a person to appear sincere when they are actually being deceptive? The answer is complicated. The CIA has a course that teaches spies how to successfully deal with interrogations by foreign intelligence services. In the course they teach the spies what deception looks and sounds like so that they know what not to do or say. The challenge is translating what they learn to a real interrogation.

Even with a lot of practice it is very difficult to disguise non-verbal/physiological deception indicators. These are part of how we are made and we are fighting against millions of years of genetic engineering to overcome these habitual and automatic reactions to the stress we feel when we lie and fear detection.


Let me give you an example. Let’s say the person being questioned is sitting down. As they are sitting parts of their body are at rest (back and butt against the chair, arms on the arm rests, one foot on the floor, one leg crossed over the other). I call these “sleep points.” A major sign that someone is lying to you is when one or more sleep points wake up when they answer your question. What you may see is the person uncross their legs or lean forward. This is the person’s automatic reaction to the stress they feel about lying and potentially getting caught when answering your question. Remember, even well trained spies have difficulty keeping their sleep points from waking up when they lie.

One thing that I am very critical of is the dramatic liberties that authors take in describing bad guys and the way they lie, cheat and steal. My goal is for you to learn what deception looks and sounds like so that you describe it accurately. I provide many resources to help you on your journey, including consulting.

So you can gain value from reading this blog I have listed some key points to remember to make your dishonest characters seem believable to your readers:

· Everyone lies for what they mentally justify as a good reason

· No one wants to be called a liar or labeled as dishonest

· Liars have a difficult time keeping their story straight

· Truthful behavior can be faked and can make the liar appear honest

· You must look and listen in a focused manner to identify deception

· A minor verbal or physiological clue can indicate deception

· An interrogation can make an honest person appear as a liar

· There is a magic way to ask a question to trap the liar
