With a focus on cheaters, this presentation covers the basics of the mechanics of lying and ways to break a liar.
Types of lies fall into four categories. The four categories are: omission - leaving something important out of the story; commission - fabricating a story; embellishment - adding a few "extras" to the story; and transference - co-opting pieces of someone else's story.
Let's focus on the first two types, which are what cheaters usually rely on.
Jessica (to her boyfriend Dan): "Where did you and Chad go last night after the movie?"
Dan: "We had a drink at Zola and then went home."
Dan omits the part where he met a sexy cocktail waitress and had a nightcap at her place after Zola closed.
Chad (to his girlfriend Jill): What did you and Jessica do after the concert?
Jill: "We were hanging out in the lobby and the bass guitarist stopped to talk to us as he was on his way out of the theater. Then she and I left, had a drink at Posh and then came home."
Jill actually went backstage and flirted with the bass guitarist, who took her out for a drink at Posh... for starters. Chad asked a very specific question that enabled an easy omission from Jill, but instead she invented a story.
Notice that both of these lies involved other people--keep that in mind later when we talk about breaking a liar.
Notice something else: These cheaters were ready with their lies; they were canned and ready to deliver. When we get into the mechanics of lying a little more, you will see how some of the more unprepared liars try to get away with their deceit.
