    J.J. Newberry was a trained federal agent, skilled in the art of deception detection. So when a witness to a shooting sat in front of him and tried to tell him that when she heard gunshots she didn't look, she just ran -- he knew she was lying.

    How did Newberry reach this conclusion? The answer is by recognizing telltale signs that a person isn't being honest, like inconsistencies in a story, behavior that's different from a person's norm, or too much detail in an explanation.

    While using these signs to catch a liar takes extensive training and practice, it's no longer only for authorities like Newberry. Now, the average person can become adept at identifying dishonesty, and it's not as hard as you might think. Experts tell WebMD the top 10 ways to let the truth be known.

    Tip No. 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," says Newberry. "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," says Newberry. "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?"
