As the text book mentioned, "We all lie" (Lilienfeld, 2010). What we called lie is not always serious as much as in the criminal justice system. It may not be true that there might be a person who never lied in his/her life. However, include me, many of people have had at least once of an experience of lying to someone. However, not all of us seriously rebuked in front of the law. I'm not saying that lie is good, but not always considered deeply as crime.
Lie as my personal definition, I defined as the violation of truthful saying against social norms and moral expectations as a small part. Thus, we do not apply polygraph test or other methods for detecting lies to everyone at a single time we have suspicions. Then what about the white lies? I raised this question for the whole time while I was reading the text book and some articles and posts about the program "Lie to me". No matter what they purposed for lie, people's physiological actions react on the lies which enables us to catch whether they are lying or not through polygraph. However, the white lies that mostly considered as telling the untruth intentionally to avoid hurting someone's feelings. (Miffin Company, 2009). For instance, in a restaurant you definitely heard "it will be served in a minute", but that often takes more than a time, sometimes people loss of their patient. But why do they say that all the time? Do they even feel a prick of conscience at what they said? In this case, if we apply polygraph test, based on the Pinocchio response, can we identify their lies?
I basically brought such ironic question to you not just because of my curiosity, but also kind of way to look at the subject in a diversity of aspects.
