Dan Ribacoff has been a private investigator for over 23 years — he’s definitely encountered his fair share of liars. Now, Ribacoff is exposing all his PI secrets — everything from how to hunt down someone to protecting yourself from identity theft — in his new book “I Spy: How To Be Your Own Private Investigator.” Here, we share his best tips for how to tell if someone is lying.
They evade the truth. In his book, Ribacoff points out that people who feel guilty about lying won’t lie outright — they will just avoid answering the question. For example, if you ask your partner, “Did you cheat on me?” That person may answer, “Why would I do that? I have you!”
They have delayed responses with filler words. Ribacoff says if the person at hand uses a lot of "ums," "you knows" and "excuse mes," they are trying to stall to come up with a believable lie. Be on the lookout!
