Even if you’re in a perfectly good mood, according to Gaspar and Schweitzer, an interpersonal situation itself can produce emotions that prompt lying. A friend talking about how much weight she has lost by dieting makes you feel envious because this is a goal you were, coincidentally, hoping to achieve as well. The feeling of envy that accompanies this situation leads you to tell the obvious untruth that you lost even more weight. In the moment, it was the painful comparison you made of yourself and the other person that cause you to lie. You can imagine this happening in other areas as well, such as grades, income, or honors and awards. As Gaspar and Schweitzer point out, you may also be motivated to lie by the emotion expressed by the other person. If your exaggerated claims are met with admiration, you’ll only want to go further. Having a gullible person to talk to is like emotional food for the liar.
