Someone who’s disgusted wrinkles his or her nose and has narrowed eyes. Usually the mouth parts somewhat because of the nose wrinkling.
More to Watch Out For
Beyond microexpressions, there are a few telltale signs that someone’s not being genuine. For example, most real expressions last a few seconds—four or five, tops. If someone’s huge smile or scared look lasts longer than that, it’s suspect. Some also believe that eye movements during story-telling say something about truthfulness. Eyes moving upward and to the right when explaining something might mean the person’s searching through his or her brain bank for details, whereas looking up and to the left suggests a deceptive tale. (This would be reversed if he or she’s left-handed.)
According to Ekman, it’s better to look at the upper part of the face because it’s harder to control our impulsive facial expressions in that area, such as narrowed eyes or raised eyebrows. So if you’re watching someone’s face for signs revealing their inner thoughts, focus on that area first.
One Piece of the Puzzle
Even the most educated experts at lie detection can’t get it right every time and that’s because humans are complex creatures with a multitude of mannerisms that vary in meaning. We can learn to recognize facial expressions—and even to see the flashes of expressions that give away our inner thoughts—but that alone won’t tell us what’s behind the hidden emotions.
In other words, seeing a significant other’s half-second fearful look while they’re explaining why they were out so late is significant, but it doesn’t indicate that they’re lying. If anything, they might just be afraid you won’t believe the truth. Either way, you’ll know there’s an issue worth exploring. Reading faces may not be foolproof, but at least it gives us something to work with.
