trivia

resting bitch face

is universal when an individual is unobserved, but, when in public, some, like the Japanese, mask negative expressions.

I tested this formulation in a series of studies that showed that when alone Japanese and Americans displayed the same facial expressions in response to seeing films of surgery and accidents, but when a scientist sat with them as they watched the films, the Japanese more than the Americans masked negative expressions with a smile. In private, innate expressions... in public, managed expressions.7 (Ekman 1999: 21)
