Christine Lagarde, Managing Director of the International Monetary Fund (IMF) is captured here in a moment of true surprise. Sincere surprise is the most evanescent of all emotions, thus images of it are rarely captured. If surprise lasts longer than a second or two - there is usually a forced (feigned) component present. Surprise nearly always rapidly gives way to another emotion - very commonly, joy-laughter, anger, fear or embarrassment. Therefore, the lack of a second, quick, follow-up emotion - is another factor which should raise the suspicion of falsified surprise. Ms. Lagarde has all the facial components of surprise in this photo - the classic oval-round mouth opened with a dropped jaw, the contracted and elevated forehead (and thus has furrows across its entire width), raised eyebrows - and the most difficult to fake - widely opened eyelids. Many people will often insincerely try to express the emotion of surprise - however they rarely open their eyes in this "white and wide" manner.
