New researchers found out that liars often appear to telling the truth. They don't have trouble making a direct eye contact and even don't sweat more during the interview with cop. The guilty don't fidget. As a matter of fact, research indicates that innocent people tend to be more nervous when they are being questioned because they are very intent on proving that they didn't do it. The whole tenor of an encounter with police can make it harder for them to remember things accurately.

People telling the truth have no script because, basically, they lived the story. So they tend to recall unrelated details and often make mistakes. Liars come in with making up a story prepare an airtight, simple script that is easy to remember.

"A lot of different signs of anxiety are mistaken for signs of deception. In interrogation the whole goal is to convince somebody or trick them or coerce them whatever it takes to get them to confess to the crime." says Kevin Colwell, a forensic scientist at Southern Connecticut State University in New Haven.

Colwell is on the forefront of a movement to change that mindset and convince law enforcement and other interrogators that encounters with suspects are opportunities to get information, not just a moment to elicit a confession. The concern is that if an interviewer is already convinced that someone committed the crime they are investigating, interviewers stop searching for other answers. And that can lead to mistakes.

Seek Information, Not a Confession:
This approach, of seeking information rather than a confession, is already well entrenched in Britain. Back in the mid-1980s, after a raft of cases involving false confessions, British courts ruled that officers were no longer allowed to use aggressive techniques — such as lying about evidence — to goad suspects. Interrogations in Britain also have to be taped. This has changed the way UK officers interview a suspect. They chat them up, and start by asking questions to which they already know the answers. The police in Britain say this shift in strategy hasn't reduced the number of confessions.


Colwell and Hiscock-Anisman have been working on a system that draws that contrast more vividly. And they've been taking their theories out into the field. They are training police officers across the country to look for verbal patterns instead of fidgets.


Ask a Simple Question:
Basically the system asks an interviewer to pay attention to words and verbal cues rather than focusing on non-verbal communication. Hiscock-Anisman suggests interviewers begin with a non-threatening question. "For example, when I was living in Texas and I was running inmates for one of my studies we asked, 'what was the first day like for you in prison?'" she said. She chose that question for two reasons: it was a vivid memory, and it was very likely to get a truthful answer.

"There's no need to lie about your first day in prison, even if you're an inmate," she said.

The first question is designed to give interviewers a baseline of sorts. It gives them an idea of how much detail someone provides when they are telling a story truthfully. The research indicates that a person who is being honest tends to provide tons of little facts, anecdotal details that you only get from living a situation. Next, interviewers are supposed to ask the person to tell them about the event under investigation. Then they compare the two stories. Does the suspect use the same number of descriptive phrases? Is there the same kind of recall? All these things are very important when trying to turn a gut instinct about whether someone is lying, into something more rooted in specific patterns.

Then comes the harder question, which Hiscock-Anisman says often separates the liars from the truth-tellers. "I say, now what I want you to do is I want you to go back to that time and I want you to describe every single thing that happened but this time I want you to tell me what happened last and work all the way backwards," she said. She laughs. "A liar is going to have a hell of a time, right?"

Now he sees this approach as another tool for his interview toolbox.
