Memorandum Date: 11/23/2011 To: From: Re: Informative Speech Outline 2 Topic: How to catch a liar Audience Analysis: Because people are dishonest and many members of my audience have difficulties intuitively picking up on dishonesty, I will offer behaviors that suggest deception. General Purpose: To inform Specific Purpose: To inform my audience on how to catch a liar. Thesis: Liars leak expressions that give clues to their deceit and knowing how to read these clues will assist in how best to handle any given situation. INTRODUCTION I. Story of my best friend lying to me about her pregnancy. II. We get lied to all the time.
People are dishonest out of politeness, to avoid punishment, to protect others, or for personal gain. Liars leak non-verbal information that slip out without being realized. III. Acknowledging these deceptive clues will help to determine the truth. IV. I will discuss several micro and suppressed expressions (genuine emotions that flash across someone’s face in one-fifth of a second) that suggest deceit. BODY I. Knowing the person’s baseline behavior and then evaluating their gesture cluster will benefit your search for the truth. A. Analyze any differences between the person’s current behavior and their normal behaviors.
B. Observe their gesture cluster; the person’s movements, postures, and actions. C. If you are not familiar with the person, be aware of their gesture cluster and make note of the following clues to help you determine if they are, in fact, lying. II. It’s likely the person is lying if you notice he/she experiencing: A. inconsistencies between what’s being said and his/her body language. B. an increased blink rate or eyelid flutter. C. a downward gaze after asserting innocence. D. shorter or less descriptive statements. E. a decrease in his/her gestures. F. fidgeting feet that shuffle, stretch, curl, or kick out.
G. face touching especially around the mouth and nose. I. discrepancies in timing e. g. quick or lengthy responses. J. dilated pupils. Roger Johnson November 23, 2011 Page 2 III. Drawbacks: A. There is no absolute signal for deception. However, these behaviors are signs of heightened anxiety, which most liars endure. B. These expressions can help to detect deceit. However, it does not give you the reason why or what the lie actually means. CONCLUSION I. While using these clues to catch a liar takes practice, it’s no longer only for authorities or professionals.
Now, the average person can become adept at identifying dishonesty. II. To recap: A. Notice inconsistencies between the person’s current and normal behavior. B. Observe the person’s non-verbal expressions. __________________________________________ Supporting Materials (Citations) Imprint Training Center. (2010, December 25). How to Catch a Liar.
