Chapter 4: Vocal Displays, Voice Tone and Language Patterns

Interesting Fact: Many studies have shown the more a child is punished, the more likely they are to lie.

What we say might not be important as how we say it. Voice tone, vocal patterns and word choice are great clues for spotting lies and hidden emotions.

In a 2004 study researchers found that liars are much more talkative and use a third more words than people telling the truth. This is because liars tend to provide more and more detail to convince you of their lie. The most effective lie detection technique is to stay quiet and listen. You want to see if and how the other person fills the silence. And then continue to ask open-ended questions

Interesting Fact: 85% of college age couples lied about prior relationships. We intuitively know to ask open-ended questions and search for deeper meaning when we think we are being lied to. To test this point researchers had two groups of people participate in online chats.

In one group people were told the truth. In another people were told lies by the other person chatting with them. The group being lied to asked far more questions than the group hearing the truth. Somehow people knew there was

something fishy going on and kept digging deeper. This is exactly how you should behave in a situation where you want the truth—keep quiet until they stop talking and then continue to ask open-ended questions.

Phone calls and person-to-person interaction is where the most lies happen. A study conducted over a weeklong period found there were lies in:

37% of phone calls

27% of face to face

21% of IM chats

14% of emails

Researchers think this is because people do not like lying ‘on paper’ where it can be saved and re-shared. This is why it is always good to follow up in-person meetings with a summary email the subject can confirm.

There are a few things to look out for when speaking to someone on the phone or in person before following up in writing. Let’s review some of the verbal clues for deception in conversation.

Verbal Clues to Deception

1. Delayed Responses When people delay their response by repeating your question, or say things like “let me think about that,” they are often stalling for time to concoct their lie. They might also delay with parrot statements or by repeating your own previous words. Delayed responses might also avoid answering all together, “Is everyone having to answer this?” or “I’m so busy right now I don’t think I can get into this with you.” These are all avoidance answers and should be seen as red flags. They might also say, “Let me think” or “As far as I can recall.” These both delay the response. An honest person will want the truth out as soon as possible.

2. Answering with Generalizations Another way people delay their response to buy time to think about their lie is by answering with a sweeping

generalization. This is a way of avoiding having to flat out lie.
