Detecting Dishonesty


Tip 1: Inconsistencies

"When you want to know if someone is lying, look for inconsistencies in what they are saying," says Newberry, who was a federal agent for 30 years and a police officer for five.

When the woman he was questioning said she ran and hid after hearing gunshots—without looking—Newberry saw the inconsistency immediately.

"There was something that just didn't fit," Newberry says. "She heard gunshots, but she didn't look? I knew that was inconsistent with how a person would respond to a situation like that." So when she wasn't paying attention, he banged on the table. She looked right at him.

"When a person hears a noise, it's a natural reaction to look toward it," Newberry tells WebMD. "I knew she heard those gunshots, looked in the direction from which they came, saw the shooter and then ran."

Sure enough, he was right.

"Her story was just illogical," Newberry says. "And that's what you should look for when you're talking to someone who isn't being truthful. Are there inconsistencies that just don't fit?"
