The names change but the faces stay the same….
The New York Times called Dan Hill, the president of Sensory Logic, a market-research firm in Minneapolis that uses facial expressions to quantify emotional response to explain the face that every politician makes when confessing they lied about something naughty. He explained:
Lips pursed and pulled tight is a sign of anger. Anger as an emotion typically means you feel like you’re not in control of circumstances. It arises from lack of progress, confusion, feelings that one’s being dealt with unfairly, i.e. resentment. These are powerful men used to being in charge. So it likely signifies feeling vulnerable (not in control).
The chin raiser, where the chin boss pushes upward, causing the lower lip to push upward, could also be called an upside-down smile. It’s a muscle movement implicated in expressions of anger, disgust and sadness.
Disgust is an emotion that relates back, in evolutionary terms, to “bad taste” or “bad smell.” The bad-taste version is as if to protect the mouth from taking in something that is poisonous. Clearly, these scandals are (sometimes fatally) poisonous to the politicians’ careers. It’s as if the whiff of scandal tastes bad to them.
Eyes and head down both correspond to sadness, i.e., disappointment in oneself. Regret. Like disgust, it’s a sign of withdrawal, as if to remove oneself from what has caused shame or embarrassment.
The basic package you’ve got here is anger, disgust and sadness.
